control open apps

This protocol allows clients such as a taskbar to request the compositor to preform typical actions on open toplevels. The compositor is in all cases free to ignore the request.

destroy()
destroy the zcosmic_toplevel_manager_v1

This request indicates that the client has finished using the zcosmic_toplevel_manager_v1 object and that it can be safely destroyed.

Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be closed

If the compositor honors this request, the zcosmic_toplevel_handle_v1.closed event will be sent.

activate(toplevel: object<zcosmic_toplevel_handle_v1>, seat: object<wl_seat>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
seatobject<wl_seat>
request that a toplevel be activated

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

set_maximized(toplevel: object<zcosmic_toplevel_handle_v1>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be maximized

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

unset_maximized(toplevel: object<zcosmic_toplevel_handle_v1>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be unmaximized

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

set_minimized(toplevel: object<zcosmic_toplevel_handle_v1>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be minimized

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

unset_minimized(toplevel: object<zcosmic_toplevel_handle_v1>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be unminimized

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

set_fullscreen(toplevel: object<zcosmic_toplevel_handle_v1>, output: object<wl_output>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
outputobject<wl_output>allow null
request that a toplevel be fullscreened

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state and potentially the zcosmic_toplevel_handle_v1.output_enter/output_leave events will be sent.

The output parameter a hint to the compositor and may be ignored. A value of NULL indicates that the compositor should choose the target output, if it honors the fullscreen request.

unset_fullscreen(toplevel: object<zcosmic_toplevel_handle_v1>)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
request that a toplevel be unfullscreened

If the compositor honors this request, the zcosmic_toplevel_handle_v1.state event will be sent.

set_rectangle(toplevel: object<zcosmic_toplevel_handle_v1>, surface: object<wl_surface>, x: int, y: int, width: int, height: int)
Argument
Type
Description
toplevelobject<zcosmic_toplevel_handle_v1>
surfaceobject<wl_surface>
xint
yint
widthint
heightint
designate a rectangle to represent a toplevel

If a client using this protocol displays UI elements corresponding to toplevels, it may use this request to inform the server about such a relation. This information may be used by the server, for example as the target for a minimize animation.

If the client sets more than one rectangle, only the most recently set rectangle is considered.

The dimensions are given in surface-local coordinates.

Setting width=height=0 removes the current rectangle if one was set.

move toplevel to workspace

Move window to workspace, on given output.

capabilities(capabilities: array)
Argument
Type
Description
capabilitiesarray
array of 32-bit capabilities
compositor capabilities

This event advertises the capabilities supported by the compositor. If a capability isn't supported, clients should hide or disable the UI elements that expose this functionality. For instance, if the compositor doesn't advertise support for closing toplevels, a button triggering the close request should not be displayed.

The compositor will ignore requests it doesn't support. For instance, a compositor which doesn't advertise support for closing toplevels will ignore close requests.

Compositors must send this event once after creation of an zcosmic_toplevel_manager_v1 . When the capabilities change, compositors must send this event again.

The capabilities are sent as an array of 32-bit unsigned integers in native endianness.
