Currently we use the value of spinner as it's `UIA_NamePropertyId` when a11y client application requests for it. Ideally we should use the text set by `Node.setAccessibleText()` as the `UIA_NamePropertyId`. For other controls such as Slider, ListView we use the text set by setAccessibleText() API.
Fix: Use the text set by `Node.setAccessibleText()` as the `UIA_NamePropertyId`. This means, when a11y client requests `UIA_NamePropertyId`, which is mapped to AccessibleAttribute.TEXT attribute, we shall return the accessible text. So we need another way to read out the VALUE of the Spinner. - For this we need to implement `IValueProvider` pattern for Spinner control - IValueProvider requests the value of the control using it's API `get_ValueString()` - It required to introduce a new AccessibleAttribute `VALUE_STRING` - IValueProvider also reads out if the control is editable or not, hence added `EDITABLE `case in `Spinner.queryAccessibleAttribute()` ------------- Commit messages: - Add attribute VALUE_STRING for Spinner Changes: https://git.openjdk.org/jfx/pull/1291/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1291&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8284544 Stats: 52 lines in 3 files changed: 44 ins; 4 del; 4 mod Patch: https://git.openjdk.org/jfx/pull/1291.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1291/head:pull/1291 PR: https://git.openjdk.org/jfx/pull/1291
