> No Accessible description :

I think this was fixed by issue 140161 (part of tree table view component).

The button for setting columns is not supposed to have a mnemonic - it has no text.
The Close button does not need mnemonic - Esc key can be used to close the dialog. The Evaluate button does not need it
either because it becomes the default button when editing the expression (so invoked by Enter). Buttons tied to
Esc/Enter don't need mnemonics.

This is reachable by TAB for me in today build (press TAB in Expression field); maybe fixed by 140161.

These are reachable but in a bit strange way. When the focus is switched away from the results table (via TAB) it goes
back to Expression field - while one would expect the focus will go to the Evaluate button. If Ctrl+TAB is used, the
focus switches properly to the buttons. This should be investigated. But all the buttons can also be invoked without
having focus, so this is a minor problem.

> Class    javax.swing.JEditorPane { | text/x-java }

This is the Expression field - I can switch to it via TAB without problems.

> Class    javax.swing.JScrollPane { Expression: | The expression to evaluate } 

This is probably the hidden scrollpane in which the editor component representing the Expression field is enclosed. No
reason why it should be reachable by TAB.

> Class    org.openide.explorer.view.TreeTable { N/A | N/A } 

The results view can be reached by TAB - two TABs from the Expression field, works for me in today build. The tree table
view does not paint the focus in any way if it has no content or nothing is selected. But the focus is there.

Evaluate button has no mnemonic. Alt+E is used to get to the Expression field. I don't know why I would type it again if
I am already in the Expression field.

> The expression to evaluate scroll pane is not scrollable via arrow keys nor with mousewheel.

I don't see any scroll pane in the expression field. It is supposed to be one line - scroll pane makes no sense here.


So I think the only (minor) issue is to find out why TAB moves focus from results table back to Expression field instead
of to Evaluate button.

What I found an accessible problem not reported here is that I can't expand the combo box and choose something from it
via keyboard. It's probably because the arrow keys are consumed by the editor component which theoretically can contain
more lines of code.

Well the combo problem isnt here because i showed it to mentlicher in person :)

Focus can be moved from results table to Evaluate button by pressing Ctrl+TAB.

Evaluate Expression dialog will probably be changed in NB 7.0.

Evaluate dialog is gone, therefore this is fixed. ;-)

cool fix :)
