NVDA does not announce the number of child items

[anOolamr]

NVDA does not announce the number of child items

• a collapsed node is expanded
• the keyboard focus navigates to an expanded node

See also bug report #13386.

Steps to reproduce:

1. If not available, download the SwingSet2 Demonstration Program from: https://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html#swingset2

2. Start NVDA.

3. Launch SwingSet2.jar with an up-to-date Java JRE.
   -> The SwingSet2 application window appears.

4. Navigate with arrow right key to the "JTree demo" radio button and press spacebar to select it.

5. Press Tab key twice to navigate to the JTree control.
   -> NVDA announces the "Tree" role of the JTree control.

6. Press arrow down key once to select the root node.
   -> NVDA announces the name "Music", some state information ("selected, expanded, editable") and the position ("1 of 1, level 1") of the root node.
   -> Missing announcement: number of its child items ("3 items").

7. Press arrow down key once to select the first child item of the root node.
   -> NVDA announces the level ("level 2"), the name "Classical", some state information ("selected, collapsed, editable") and the position ("1 of 3") of the node.

8. Press arrow right to expand the "Classical" tree node.
   -> NVDA announces nothing. NVDA should announce the name and the state change ("expanded") of the node and the number of its child items ("3 items").

Note: The missing expand/collapse announcement is already described in bug report #13623.

Actual behavior:

NVDA does not announce the number of child items.

level 5 No. 1 - C selected, editable 1 of 5

Expected behavior:

NVDA announces also the number of child items when

• a collapsed node is expanded
• the keyboard focus navigates to an expanded node

level 5 No. 1 - C selected, editable 1 of 5 3 child items

I don't think I have ever had these announcements for any treeview with NVDA. So do we want to expand this enhancement for other types of treeview other than Java Swing JTree? My feeling if this is done then we should look at making it more general than just Java.

Is the reasoning for this the same as #13892?

[Adriani90]

This is indeed not needed because it adds extra unneeded verbosity. When you expand an item and press down arrow key, you already will hear the number of the child elements. Closing as won't fix.
