Work breakdown

The following is a rough breakdown of work needed to create a functional native Wayland toolkit.

	Graphics
1	✅	Basic drawing support using shared memory
2	✅	CPU rendering
3	✅	Unaccelerated VolatileImage support
4	❌	Accelerated rendering support (VolatileImage)
5	✅	GraphicsEnvironment/GraphicsDevice/etc, including multiple screen support
6	✅	HiDPI
7	❌	Top-level window transparency
8	❌	Image formats (native 64bits?), HDR / color profiles?
9	❌	Color blending with transparency support	alpha, pre-multiplied?
10	❌	AlphaComposite support on client side ?	main Porter-Duff rules like CLR, SRC_OVER or more?
	Input
11	✅	Mouse	Only 3-button mice with vertical scrolling is supported
12	✅	Keyboard
13	❌	Touch (hi-resolution scrolling, gestures)
14	❌	Input methods
	GUI
15	✅	Frame decorations	Basic title bar decorations, "native" look-and-feel is a separate task
16	✅	Interactive resize/drag/minimize/maximize
17	✅	Modal and non-modal dialogs
18	❌	Correct Z-order for complex window hierarchies with modal dialogs
19	✅	Fullscreen support	~~But can't specify the device yet~~
20	❌	Tooltips, menus, comboboxes, etc
21	❌	GTK support (making GTKLookAndFeel work)
22	❌	Splash screen support
23	❌	toFront/toBack support	toFront can be implemented through an activation token (as if the window just appeared); toBack can be implemented through a synthesized gesture on the title bar (also needs mouse serial). See GTK implementation.
24	❌	AWT components (java.awt.Button, java.awt.Checkbox, etc)
25	❌	AWT File dialogs/Print dialogs
	Robot support
26	✅	For testing	No input support yet
27	❌	Full support in a production environment	Probably not feasible in full
	Misc
28	❌	Clipboard support
29	❌	Drag-n-drop support
30	❌	Taskbar/tray support

Legend:

✅ - feature is functional at the basic level (for example, mouse support means 3-button mice, nothing fancy)
❌ - task not started yet
⏳ - task is being worked on
