The mouse->CreateCursor function pointer will always be null if checked before the video backend is initialized, so a dummy default cursor with null internal structures was being created in all cases, not just for backends lacking cursor functionality. Move the check to after the video subsystem is initialized, when the function pointer check is valid.
Passing this dummy cursor with null internal structures to the Wayland backend would cause a crash, as it requires the internal cursor structures to be valid in order to store cursor backing data, even for default system cursors.
In the event that the compositor sends window dimensions of (0,0), use the last requested compositor dimensions for fullscreen windows as opposed to trying to guess the target dimensions from the output, which can be null if no outputs are present, or wrong in the case of multi-display setups. Fullscreen windows must respect the maximum dimensions reported by the compositor, or a protocol violation can result.
This also prevents possible crashes if the compositor sends a config event with dimensions of (0,0) before a display has been added and/or finalized.
main features:
- No more sdl-build-options/sdl-shared-build-options/sdl-global-options
- Dependency information is stored on SDL3-collector for sdl3.pc
- Use helper functions to modify the SDL targets;
- sdl_sources to add sources
- sdl_glob_sources to add glob soruces
- sdl_link_dependency to add a link dependency that might also
appear in sdl3.pc/SDL3Config.cmake
- sdl_compile_definitions to add macro's
- sdl_compile_options for compile options
- sdl_include_directories for include directories
They avoid repeated checks for existence of the SDL targets
- A nice feature of the previous is the ability to generate
a sdl3.pc or SDL3Config.cmake that describes its dependencies
accurately.
various:
- remove duplicate libc symbol list
- add CheckVulkan
- remove unused HAVE_MPROTECT
- add checks for getpagesize
Adds the SDL_EVENT_WINDOW_OCCLUDED events and the window flag SDL_WINDOW_OCCLUDED to report when the window occlusion state has changed, so that the application can take appropriate measures, as it may wish to suspend drawing, throttle, or otherwise behave in a more energy efficient manner when the window is not visible. When the window is no longer occluded, the SDL_EVENT_WINDOW_EXPOSED event is sent and the occlusion flag is cleared.
This is handled on macOS via the window occlusion state event (available as of 10.9), and via the xdg-shell protocol on Wayland (version 6, wayland-protocols 1.32, passed through in libdecor 0.1.2).
Currently, SDL_CLIPBOARDUPDATE events are only sent when an SDL window
has its selection cleared. This change sends the event anytime the
XFixesSelectionNotify event is raised, and when the selection is either
the clipboard or the primary selection.
The xdg_activation token requires specifying the surface that is the source of the activation request, not the surface of the target window. Setting this to the target window was causing raise requests to be blocked by the compositor, as if the surface noted as the origin of the request didn't currently have focus, it appeared to the compositor as though it was trying to 'steal' focus.
Keyboard focus was being passed to the child window being shown if SDL_HINT_WINDOW_ACTIVATE_WHEN_SHOWN is false and keyboard focus was not being passed to the child window being activated in WIN_RaiseWindow.
- Windows created minimized are shown with SW_SHOWMINNOACTIVE which does not send WM_SHOWWINDOW leaving the window visible (but minimized)
on desktop but still with the SDL_WINDOW_HIDDEN flag set. Now the hidden flag is cleared in this case but noted that this means it's not currently possible
to create a window that is initially hidden that then is minimized once shown.
video(wayland): use both --icon and --icon-name for Zenity
Many distros ship an older version of Zenity that supports GTK3, while some distros ship newer version of Zenity which uses libadwaita.
This command tries to use --icon and fall back to --icon-name when it fails.
Use the implicit grab serial, which includes keyboard key, mouse button, touch, and tablet tool events, for setting the clipboard and primary selection data, as these are all considered valid originating event serials.
This will simplify the X11 and Wayland implementations, which were doing that under the hood, and makes application interaction between the two APIs consistent.
The destination rectangle passed to SDL_BlitSurface() and SDL_BlitSurfaceScaled() is non-const and filled in with the final destination rectangle after clipping, and now documented as such.
