This protocol provides additional events and requests for special DE clients like panels, docks, etc. It is meant as an addition for protocols like wlr-layer-shell. Represents a single output. Each output is managed independently from the others. Emitted when a window gets fullscreened on the given output. In this mode, windows in the TOP layer are not visible. There will be no two consecutive enter_fullscreen calls, i.e. if fullscreen mode is entered it will be exited before going into this mode again. Emitted when the output is no longer in fullscreen mode. Each leave_fullscreen has a corresponding enter_fullscreen before it. Request the compositor to not render the output, so the output usually is cleared to black color. To enable output rendering again, call inhibit_output_done. Stop inhibiting the output. This must be called as many times as inhibit_output was called to actually uninhibit rendering. The inhibit/inhibit_done requests can be called multiple times, even from different apps, so don't assume that a call to inhibit_done would always mean actually starting the rendering process. A hotspot on the output is an edge or a corner region of the output where the mouse or touch point has been residing for a given amount of time. The hotspot can be used for example for autohiding panels, where the panel is shown when the input hovers on the edge of the output for a specific amount of time. Means that the mouse and/or touch finger was inside the indicated hotspot for the given amount of time. Emitted at most once for each entry of the input inside the hotspot. This event indicates that the mouse or touch point has left the hotspot area. Emitted only once after each enter.
