River window management

This request indicates that the client no longer wishes to receive events on this object.

The Wayland protocol is asynchronous, which means the server may send further events until the stop request is processed. The client must wait for a river_window_manager_v1.finished event before destroying this object.

This request should be called after the finished event has been received to complete destruction of the object.

If a client wishes to destroy this object it should send a river_window_manager_v1.stop request and wait for a river_window_manager_v1.finished event. Once the finished event is received it is safe to destroy this object and any other objects created through this interface.

This request indicates that the client has made all changes to window management state it wishes to include in the current manage sequence and that the server should atomically send these state changes to the windows and continue with the manage sequence.

After sending this request, it is a protocol error for the client to make further changes to window management state until the next manage_start event is received.

See the description of the river_window_manager_v1 interface for a complete overview of the manage/render sequence loop.

This request ensures a manage sequence is started and that a manage_start event is sent by the server. If this request is made during an ongoing manage sequence, a new manage sequence will be started as soon as the current one is completed.

The client may want to use this request due to an internal state change that the compositor is not aware of (e.g. a dbus event) which should affect window management or rendering state.

This request indicates that the client has made all changes to rendering state it wishes to include in the current manage sequence and that the server should atomically apply and display these state changes to the user.

After sending this request, it is a protocol error for the client to make further changes to rendering state until the next manage_start or render_start event is received, whichever comes first.

See the description of the river_window_manager_v1 interface for a complete overview of the manage/render sequence loop.

Create a new shell surface for window manager UI and assign the river_shell_surface_v1 role to the surface.

Providing a wl_surface which already has a role or already has a buffer attached or committed is a protocol error.

This event indicates that window management is not available to the client, perhaps due to another window management client already running. The circumstances causing this event to be sent are compositor policy.

If sent, this event is guaranteed to be the first and only event sent by the server.

The server will send no further events on this object. The client should destroy this object and all objects created through this interface.

This event indicates that the server will send no further events on this object. The client should destroy the object. See river_window_manager_v1.destroy for more information.

This event indicates that the server has sent events indicating all state changes since the last manage sequence.

In response to this event, the client should make requests modifying window management state as it chooses. Then, the client must make the manage_finish request.

See the description of the river_window_manager_v1 interface for a complete overview of the manage/render sequence loop.

This event indicates that the server has sent all river_node_v1.position and river_window_v1.dimensions events necessary.

In response to this event, the client should make requests modifying rendering state as it chooses. Then, the client must make the render_finish request.

See the description of the river_window_manager_v1 interface for a complete overview of the manage/render sequence loop.

This event indicates that the session has been locked.

The window manager may wish to restrict which key bindings are available while locked or otherwise use this information.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event indicates that the session has been unlocked.

This event will be followed by a manage_start event after all other new state has been sent by the server.

A new window has been created.

This event will be followed by a manage_start event after all other new state has been sent by the server.

A new logical output has been created, perhaps due to a new physical monitor being plugged in or perhaps due to a change in configuration.

This event will be followed by river_output_v1.position and dimensions events as well as a manage_start event after all other new state has been sent by the server.

A new seat has been created.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This request indicates that the client will no longer use the window object and that it may be safely destroyed.

This request should be made after the river_window_v1.closed event or river_window_manager_v1.finished is received to complete destruction of the window.

Request that the window be closed. The window may ignore this request or only close after some delay, perhaps opening a dialog asking the user to save their work or similar.

The server will send a river_window_v1.closed event if/when the window has been closed.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Get the node in the render list corresponding to the window.

It is a protocol error to make this request more than once for a single window.

This request proposes dimensions for the window in the compositor's logical coordinate space.

The width and height must be greater than or equal to zero. If the width or height is zero the window will be allowed to decide its own dimensions.

The window may not take the exact dimensions proposed. The actual dimensions taken by the window will be sent in a subsequent river_window_v1.dimensions event. For example, a terminal emulator may only allow dimensions that are multiple of the cell size.

When a propose_dimensions request is made, the server must send a dimensions event in response as soon as possible. It may not be possible to send a dimensions event in the very next render sequence if, for example, the window takes too long to respond to the first proposed dimensions. In this case, the server will send the dimensions event in a future render sequence. The window will not be displayed until the first dimensions event is received and the render sequence is finished.

Note that the dimensions of a river_window_v1 refer to the dimensions of the window content and are unaffected by the presence of borders or decoration surfaces.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Request that the window be hidden. Has no effect if the window is already hidden. Hides any window borders and decorations as well.

Newly created windows are considered shown unless explicitly hidden with the hide request.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

Request that the window be shown. Has no effect if the window is not hidden. Does not guarantee that the window is visible as it may be completely obscured by other windows placed above it for example.

Newly created windows are considered shown unless explicitly hidden with the hide request.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

Tell the client to use client side decoration and draw its own title bar, borders, etc.

This is the default if neither this request nor the use_ssd request is ever made.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Tell the client to use server side decoration and not draw any client side decorations.

This request will have no effect if the client only supports client side decoration, see the decoration_hint event.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

This request decorates the window with borders drawn by the compositor on the specified edges of the window. Borders are drawn above the window content.

Corners are drawn only between borders on adjacent edges. If e.g. the left edge has a border and the top edge does not, the border drawn on the left edge will not extend vertically beyond the top edge of the window.

Borders are not drawn while the window is fullscreen.

The color is defined by four 32-bit RGBA values. Unless specified in another protocol extension, the RGBA values use pre-multiplied alpha.

Setting the edges to none or the width to 0 disables the borders. Setting a negative width is a protocol error.

This request completely overrides all previous set_borders requests. Only the most recent set_borders request has an effect.

Note that the position/dimensions of a river_window_v1 refer to the position/dimensions of the window content and are unaffected by the presence of borders or decoration surfaces.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

Inform the window that it is part of a tiled layout and adjacent to other elements in the tiled layout on the given edges.

The window should use this information to change the style of its client side decorations and avoid drawing e.g. drop shadows outside of the window dimensions on the tiled edges.

Setting the edges argument to none informs the window that it is not part of a tiled layout. If this request is never made, the window is informed that it is not part of a tiled layout.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Create a decoration surface and assign the river_decoration_v1 role to the surface. The created decoration is placed above the window in rendering order, see the description of river_decoration_v1.

Providing a wl_surface which already has a role or already has a buffer attached or committed is a protocol error.

Create a decoration surface and assign the river_decoration_v1 role to the surface. The created decoration is placed below the window in rendering order, see the description of river_decoration_v1.

Providing a wl_surface which already has a role or already has a buffer attached or committed is a protocol error.

Inform the window that it is being resized. The window manager should use this request to inform windows that are the target of an interactive resize for example.

The window manager remains responsible for handling the position and dimensions of the window while it is resizing.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Inform the window that it is no longer being resized. The window manager should use this request to inform windows that are the target of an interactive resize that the interactive resize has ended for example.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

This request informs the window of the capabilities supported by the window manager. If the window manager, for example, ignores requests to be maximized from the window it should not tell the window that it supports the maximize capability.

The window might use this information to, for example, only show a maximize button if the window manager supports the maximize capability.

The window manager client should use this request to set capabilities for all new windows. If this request is never made, the compositor will inform windows that all capabilities are supported.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Inform the window that it is maximized. The window might use this information to adapt the style of its client-side window decorations for example.

The window manager remains responsible for handling the position and dimensions of the window while it is maximized.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Inform the window that it is unmaximized. The window might use this information to adapt the style of its client-side window decorations for example.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Inform the window that it is fullscreen. The window might use this information to adapt the style of its client-side window decorations for example.

This request does not affect the size/position of the window or cause it to become the only window rendered, see the river_window_v1.fullscreen and exit_fullscreen requests for that.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Inform the window that it is not fullscreen. The window might use this information to adapt the style of its client-side window decorations for example.

This request does not affect the size/position of the window or cause it to become the only window rendered, see the river_window_v1.fullscreen and exit_fullscreen requests for that.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Make the window fullscreen on the given output. If multiple windows are fullscreen on the same output at the same time only the "top" window in rendering order shall be displayed.

All river_shell_surface_v1 objects above the top fullscreen window in the rendering order will continue to be rendered.

The compositor will handle the position and dimensions of the window while it is fullscreen. The set_position and propose_dimensions requests shall not affect the current position and dimensions of a fullscreen window.

The compositor will clip window content, decoration surfaces, and borders to the given output's dimensions while the window is fullscreen. The effects of set_clip_box and set_content_clip_box are ignored while the window is fullscreen.

If the output on which a window is currently fullscreen is removed, the windowing state is modified as if there were an exit_fullscreen request made in the same manage sequence as the river_output_v1.removed event.

This request does not inform the window that it is fullscreen, see the river_window_v1.inform_fullscreen and inform_not_fullscreen requests.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Make the window not fullscreen.

The position and dimensions are undefined after this request is made until a manage sequence in which the window manager makes the propose_dimensions and set_position requests is completed.

The window manager should make propose_dimensions and set_position requests in the same manage sequence as the exit_fullscreen request for frame perfection.

This request does not inform the window that it is fullscreen, see the river_window_v1.inform_fullscreen and inform_not_fullscreen requests.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Clip the window, including borders and decoration surfaces, to the box specified by the x, y, width, and height arguments. The x/y position of the box is relative to the top left corner of the window.

The width and height arguments must be greater than or equal to 0.

Setting a clip box with 0 width or height disables clipping.

The clip box is ignored while the window is fullscreen.

Both set_clip_box and set_content_clip_box may be enabled simultaneously.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

Clip the content of the window, excluding borders and decoration surfaces, to the box specified by the x, y, width, and height arguments. The x/y position of the box is relative to the top left corner of the window.

Borders drawn by the compositor (see set_borders) are placed around the intersection of the window content (as defined by the dimensions event) and the content clip box when content clipping is enabled.

The width and height arguments must be greater than or equal to 0.

Setting a box with 0 width or height disables content clipping.

The content clip box is ignored while the window is fullscreen.

Both set_clip_box and set_content_clip_box may be enabled simultaneously.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

The window has been closed by the server, perhaps due to an xdg_toplevel.close request or similar.

The server will send no further events on this object and ignore any request other than river_window_v1.destroy made after this event is sent. The client should destroy this object with the river_window_v1.destroy request to free up resources.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event informs the window manager of the window's preferred min/max dimensions. These preferences are a hint, and the window manager is free to propose dimensions outside of these bounds.

All min/max width/height values must be strictly greater than or equal to 0. A value of 0 indicates that the window has no preference for that value.

The min_width/min_height must be strictly less than or equal to the max_width/max_height.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event indicates the dimensions of the window in the compositor's logical coordinate space. The width and height must be strictly greater than zero.

Note that the dimensions of a river_window_v1 refer to the dimensions of the window content and are unaffected by the presence of borders or decoration surfaces.

This event is sent as part of a render sequence before the render_start event.

It may be sent due to a propose_dimensions request in a previous manage sequence or because a window independently decides to change its dimensions.

The window set an application ID.

The app_id argument will be null if the window has never set an application ID or if the window cleared its application ID. (Xwayland windows may do this for example, though xdg-toplevels may not.)

This event will be followed by a manage_start event after all other new state has been sent by the server.

The window set a title.

The title argument will be null if the window has never set a title or if the window cleared its title. (Xwayland windows may do this for example, though xdg-toplevels may not.)

This event will be followed by a manage_start event after all other new state has been sent by the server.

The window set a parent window. If this event is never received or if the parent argument is null then the window has no parent.

A surface with a parent set might be a dialog, file picker, or similar for the parent window.

Child windows should generally be rendered directly above their parent.

The compositor must guarantee that there are no loops in the window tree: a parent must not be the descendant of one of its children.

This event will be followed by a manage_start event after all other new state has been sent by the server.

Information from the window about the supported and preferred client side/server side decoration options.

This event may be sent multiple times over the lifetime of the window if the window changes its preferences.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event informs the window manager that the window has requested to be interactively moved using the pointer. The seat argument indicates the seat for the move.

The xdg-shell protocol for example allows windows to request that an interactive move be started, perhaps when a client-side rendered titlebar is dragged.

The window manager may use the river_seat_v1.op_start_pointer request to interactively move the window or ignore this event entirely.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event informs the window manager that the window has requested to be interactively resized using the pointer. The seat argument indicates the seat for the resize.

The edges argument indicates which edges the window has requested to be resized from. The edges argument will never be none and will never have both top and bottom or both left and right edges set.

The xdg-shell protocol for example allows windows to request that an interactive resize be started, perhaps when the corner of client-side rendered decorations is dragged.

The window manager may use the river_seat_v1.op_start_pointer request to interactively resize the window or ignore this event entirely.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request that a window menu be shown, for example when the user right clicks on client side window decorations.

A window menu might include options to maximize or minimize the window.

The window manager is free to ignore this request and decide what the window menu contains if it does choose to show one.

The x and y arguments indicate where the window requested that the window menu be shown.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request to be maximized.

The window manager is free to honor this request using river_window_v1.inform_maximize or ignore it.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request to be unmaximized.

The window manager is free to honor this request using river_window_v1.inform_unmaximized or ignore it.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request that they be made fullscreen and allows them to provide an output preference.

The window manager is free to honor this request using river_window_v1.fullscreen or ignore it.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request to exit fullscreen.

The window manager is free to honor this request using river_window_v1.exit_fullscreen or ignore it.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The xdg-shell protocol for example allows windows to request to be minimized.

The window manager is free to ignore this request, hide the window, or do whatever else it chooses.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event gives an unreliable PID of the process that created the window. Obtaining this information is inherently racy due to PID reuse. Therefore, this PID must not be used for anything security sensitive.

Note also that a single process may create multiple windows, so there is not necessarily a 1-to-1 mapping from PID to window. Multiple windows may have the same PID.

This event is sent once when the river_window_v1 is created and never sent again.

This request indicates that the client will no longer use the decoration object and that it may be safely destroyed.

This request sets the offset of the decoration surface from the top left corner of the window.

If this request is never sent, the x and y offsets are undefined by this protocol and left up to the compositor.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

Synchronize application of the next wl_surface.commit request on the decoration surface with rest of the state atomically applied with the next river_window_manager_v1.render_finish request.

The client must make a wl_surface.commit request on the decoration surface after this request and before the render_finish request, failure to do so is a protocol error.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request indicates that the client will no longer use the shell surface object and that it may be safely destroyed.

Get the node in the render list corresponding to the shell surface.

It is a protocol error to make this request more than once for a single shell surface.

Synchronize application of the next wl_surface.commit request on the shell surface with rest of the rendering state atomically applied with the next river_window_manager_v1.render_finish request.

The client must make a wl_surface.commit request on the shell surface after this request and before the render_finish request, failure to do so is a protocol error.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request indicates that the client will no longer use the node object and that it may be safely destroyed.

Set the absolute position of the node in the compositor's logical coordinate space. The x and y coordinates may be positive or negative.

Note that the position of a river_window_v1 refers to the position of the window content and is unaffected by the presence of borders or decoration surfaces.

If this request is never sent, the position of the node is undefined by this protocol and left up to the compositor.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request places the node above all other nodes in the compositor's render list.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request places the node below all other nodes in the compositor's render list.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request places the node directly above another node in the compositor's render list.

Attempting to place a node above itself has no effect.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request places the node directly below another node in the compositor's render list.

Attempting to place a node below itself has no effect.

This request modifies rendering state and may only be made as part of a render sequence, see the river_window_manager_v1 description.

This request indicates that the client will no longer use the output object and that it may be safely destroyed.

This request should be made after the river_output_v1.removed event is received to complete destruction of the output.

This event indicates that the logical output is no longer conceptually part of window management space.

The server will send no further events on this object and ignore any request (other than river_output_v1.destroy) made after this event is sent. The client should destroy this object with the river_output_v1.destroy request to free up resources.

This event may be sent because a corresponding physical output has been physically unplugged or because some output configuration has changed.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The wl_output object corresponding to the river_output_v1. The argument is the global name of the wl_output advertised with wl_registry.global.

It is guaranteed that the corresponding wl_output is advertised before this event is sent.

This event is sent exactly once. The wl_output associated with a river_output_v1 cannot change. It is guaranteed that there is a 1-to-1 mapping between wl_output and river_output_v1 objects.

The global_remove event for the corresponding wl_output may be sent before the river_output_v1.remove event. This is due to the fact that river_output_v1 state changes are synced to the river window management manage sequence while changes to globals are not.

Rationale: The window manager may need information provided by the wl_output interface such as the name/description. It also may need the wl_output object to start screencopy for example.

This event indicates the position of the output in the compositor's logical coordinate space. The x and y coordinates may be positive or negative.

This event is sent once when the river_output_v1 is created and again whenever the position changes.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The server must guarantee that the position and dimensions events do not cause the areas of multiple logical outputs to overlap when the corresponding manage_start event is received.

This event indicates the dimensions of the output in the compositor's logical coordinate space. The width and height will always be strictly greater than zero.

This event is sent once when the river_output_v1 is created and again whenever the dimensions change.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The server must guarantee that the position and dimensions events do not cause the areas of multiple logical outputs to overlap when the corresponding manage_start event is received.

This request indicates that the client will no longer use the seat object and that it may be safely destroyed.

This request should be made after the river_seat_v1.removed event is received to complete destruction of the seat.

Request that the compositor send keyboard input to the given window.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Request that the compositor send keyboard input to the given shell surface.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Request that the compositor not send keyboard input to any client.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Start an interactive pointer operation. During the operation, op_delta events will be sent based on pointer input.

When all pointer buttons are released, the op_release event is sent.

The pointer operation continues until the op_end request is made during a manage sequence and that manage sequence is finished.

The window manager may use this operation to implement interactive move/resize of windows by setting the position of windows and proposing dimensions based off of the op_delta events.

This request is ignored if an operation is already in progress.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

End an interactive operation.

This request is ignored if there is no operation in progress.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

Define a pointer binding in terms of a pointer button, modifiers, and other configurable properties.

The button argument is a Linux input event code defined in the linux/input-event-codes.h header file (e.g. BTN_RIGHT).

The new pointer binding is not enabled until initial configuration is completed and the enable request is made during a manage sequence.

Set the XCursor theme for the seat. This theme is used for cursors rendered by the compositor, but not necessarily for cursors rendered by clients.

Note: The window manager may also wish to set the XCURSOR_THEME and XCURSOR_SIZE environment variable for programs it starts.

Warp the pointer to the given position in the compositor's logical coordinate space.

If the given position is outside the bounds of all outputs, the pointer will be warped to the closest point inside an output instead.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

This event indicates that seat is no longer in use and should be destroyed.

The server will send no further events on this object and ignore any request (other than river_seat_v1.destroy) made after this event is sent. The client should destroy this object with the river_seat_v1.destroy request to free up resources.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The wl_seat object corresponding to the river_seat_v1. The argument is the global name of the wl_seat advertised with wl_registry.global.

It is guaranteed that the corresponding wl_seat is advertised before this event is sent.

This event is sent exactly once. The wl_seat associated with a river_seat_v1 cannot change. It is guaranteed that there is a 1-to-1 mapping between wl_seat and river_seat_v1 objects.

The global_remove event for the corresponding wl_seat may be sent before the river_seat_v1.remove event. This is due to the fact that river_seat_v1 state changes are synced to the river window management manage sequence while changes to globals are not.

Rationale: The window manager may want to trigger window management state changes based on normal input events received by its shell surfaces for example.

The seat's pointer entered the given window's area.

The area of a window is defined to include the area defined by the window dimensions, borders configured using river_window_v1.set_borders, and the input regions of decoration surfaces. In particular, it does not include input regions of surfaces belonging to the window that extend outside the window dimensions.

The pointer of a seat may only enter a single window at a time. When the pointer moves between windows, the pointer_leave event for the old window must be sent before the pointer_enter event for the new window.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The seat's pointer left the window for which pointer_enter was most recently sent. See pointer_enter for details.

This event will be followed by a manage_start event after all other new state has been sent by the server.

A window has been interacted with beyond the pointer merely passing over it. This event might be sent due to a pointer button press or due to a touch/tablet tool interaction with the window.

There are no guarantees regarding how this event is sent in relation to the pointer_enter and pointer_leave events as the interaction may use touch or tablet tool input.

Rationale: this event gives window managers necessary information to determine when to send keyboard focus, raise a window that already has keyboard focus, etc. Rather than expose all pointer, touch, and tablet events to window managers, a policy over mechanism approach is taken.

This event will be followed by a manage_start event after all other new state has been sent by the server.

A shell surface has been interacted with beyond the pointer merely passing over it. This event might be sent due to a pointer button press or due to a touch/tablet tool interaction with the shell_surface.

There are no guarantees regarding how this event is sent in relation to the pointer_enter and pointer_leave events as the interaction may use touch or tablet tool input.

Rationale: While the shell surface does receive all wl_pointer, wl_touch, etc. input events for the surface directly, these events do not necessarily trigger a manage sequence and therefore do not allow the window manager to update focus or perform other actions in response to the input in a race-free way.

This event will be followed by a manage_start event after all other new state has been sent by the server.

This event indicates the total change in position since the start of the operation of the pointer/touch point/etc.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The input driving the current interactive operation has been released. For a pointer op for example, all pointer buttons have been released.

Depending on the op type, op_delta events may continue to be sent until the op is ended with the op_end request.

This event is sent at most once during an interactive operation.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The current position of the pointer in the compositor's logical coordinate space.

This state is special in that a change in pointer position alone must not cause the compositor to start a manage sequence.

Assuming the seat has a pointer, this event must be sent in every manage sequence unless there is no change in x/y position since the last time this event was sent.

This enum is used to describe the keyboard modifiers that must be held down to trigger a key binding or pointer binding.

Note that river and wlroots use the values 2 and 16 for capslock and numlock internally. It doesn't make sense to use locked modifiers for bindings however so these values are not included in this enum.

This request indicates that the client will no longer use the pointer binding object and that it may be safely destroyed.

This request should be made after all initial configuration has been completed and the window manager wishes the pointer binding to be able to be triggered.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

This request may be used to temporarily disable the pointer binding. It may be later re-enabled with the enable request.

This request modifies window management state and may only be made as part of a manage sequence, see the river_window_manager_v1 description.

This event indicates that the pointer button triggering the binding has been pressed.

This event will be followed by a manage_start event after all other new state has been sent by the server.

The compositor should wait for the manage sequence to complete before processing further input events. This allows the window manager client to, for example, modify key bindings and keyboard focus without racing against future input events. The window manager should of course respond as soon as possible as the capacity of the compositor to buffer incoming input events is finite.

This event indicates that the pointer button triggering the binding has been released.

Releasing the modifiers for the binding without releasing the pointer button does not trigger the release event. This event is sent when the pointer button is released, even if the modifiers have changed since the pressed event.

This event will be followed by a manage_start event after all other new state has been sent by the server.
