Accessibility is not implemented for JavaFX dialogs. This change is to implement the accessibility on windows platform. Without this fix : On Windows platform, content of Dialog are not read by Windows Narrator or JAWS. With this fix: 1. Windows narrator reads the dialog correctly 2. JAWS fails to read the header text. : This will be handled separately 3. Behavior of VoiceOver on MacOS remains unchanged : This will be handled separately.
Verification: 1. Run HelloAlert toy app, with fix. 2. Start Windows Narrator 3. Click on the different buttons to show different Dialogs => Observe that Narrator reads all the content correctly. ------------- Commit messages: - unit test - Add DIALOG role Changes: https://git.openjdk.org/jfx/pull/873/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=873&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8087557 Stats: 36 lines in 5 files changed: 34 ins; 1 del; 1 mod Patch: https://git.openjdk.org/jfx/pull/873.diff Fetch: git fetch https://git.openjdk.org/jfx pull/873/head:pull/873 PR: https://git.openjdk.org/jfx/pull/873
