Enumeration Type Documentation

eGWL_PendingWindowActions

enum eGWL_PendingWindowActions

Enumerator
PENDING_WINDOW_FRAME_CONFIGURE	The state of the window frame has changed, apply the state from GWL_Window::frame_pending.
PENDING_OUTPUT_SCALE_UPDATE	The DPI for a monitor has changed or the monitors (outputs) this window is visible on may have changed. Recalculate the windows scale.
PENDING_OUTPUT_SCALE_UPDATE_DEFERRED	Workaround for a bug/glitch in WLROOTS based compositors (RIVER for e.g.). Deferring the scale update one even-loop cycle resolves a bug where the output enter/exit events cause the surface buffer being an invalid size. While these kinds of glitches might be ignored in some cases, this caused newly created windows to immediately loose the connection to WAYLAND (crashing from a user perspective).
PENDING_WINDOW_SURFACE_COMMIT	The surface needs a commit to run. Use this to avoid committing immediately which can cause flickering when other operations have not yet been performed - such as refreshing the window size.
PENDING_WINDOW_CURSOR_SHAPE_REFRESH	The window has gained focus and the cursor shape needs to be refreshed.

gwl_window_activate()

static void gwl_window_activate ( GWL_Window * win )

static

Unlike GHOST_WindowWayland::activate which responds to WAYLAND having set the window active. This function makes a request to WAYLAND for the window to become active.

Note

The request may be ignored and may not work on all compositors.

LIBDECOR support committing a window-configuration in the main-thread that was handled in a non-main-thread.

This is needed for proper order of operations as the commit needs to occur after the buffer is resized (something that can't be done from a non-main thread). Without this, the window-frame can get out of sync with its contents and resizing is slow.

Eventually LIBDECOR should support copying & freeing a configuration, even when it does, older versions of the library will to be supported and the workaround will need to be kept. See: https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/64 Queue configuration calls until a valid window frame size is available. This is needed because LIBDECOR has an issue where windows initialized with a zero size don't have a usable title bar. see #117583.
