QtCS 2018: Wayland topics

Back to Qt contributors summit 2018 Program

General

• Deprecating old shells (xdg-shell v5, wl-shell, eventually xdg-shell v6)
• Subsurfaces

Client

• Making APIs public?
• Solving the backing store flickering problem (mostly on gnome-shell).
• QtBase popup model (tree) doesn't match xdg-shell (linear stack)
• Window decorations
  • Improving looks
  • Supporting server-side decorations
• Avoid unnecessary deletions of wl_surface/xdg_surface? (attaching null buffers)

Compositor

• Towards Qt 6
  • Use pointer handlers?
  • Remove sizeFollowsSurface
  • Change defaults:
    • autoCreatePopupItems: true
    • sizeFollowsWindow: true
    • windowSystemCursorEnabled: nested ???O
  • Make APIs for different shells source compatible (duck typing)?
• Support windowless compositor
  • Make window property optional in WaylandOutput?
• Move extensions to QML modules? e.g. import QtWaylandCompositor.XdgShell 1.0
• Support multiple client buffer integrations simultaneously
