AccessibleStates

Remarks

Named after .NET's own System.Windows.Forms.AccessibleStates and populated from ARIA's state attributes — aria-checked, aria-expanded, aria-selected, aria-readonly, aria-required, aria-invalid, aria-busy, aria-modal, aria-multiselectable, aria-multiline, aria-pressed. The four with no ARIA attribute behind them — Focused, Focusable, Editable and Expandable — are AT-SPI2 state names, because ARIA expresses those three by omitting an attribute and an in-process tree has to be able to say them.

⚠ Expandable is separate from Expanded because aria-expanded has three values and a flag has two. Absent means "this does not expand"; false means "it does and it is closed". Folding them would make every button in the document report itself as a collapsed disclosure.

⚠ Checked and Pressed are not the same state and the difference is not cosmetic. A checkbox is aria-checked; a toggle button in a toolbar is aria-pressed, and a screen reader says "pressed"/"not pressed" for one and "ticked"/"unticked" for the other. Both are Checked in the cascade, which is why the accessible state is computed by the control rather than read off the style flags.
