Hi,

The Gallery seems to swallow/prevent normal ESC key handling when you add
it to a Wizard Dialog. Is this a known thing? I can't see any bugs raised
for this. Or maybe I've not spotted some setX() that's required?!

Thanks,
Justin

Hi Justin,

This is strange. To cancel normal key handling, Gallery should set
event.doit=false somewhere. Currently this is only done if you use the
scrolling smoother and only for mouse wheel events.

Please check you don't have the same problem with a Canvas instead of a
Gallery. If the problem still occurs with Canvas, open a bug on SWT,
else, open a bug on Gallery and attach a snippet showing the problem.

Thanks,

Hi Nicolas,

Yes, I couldn't see anywhere in the source that's causing this, very odd.

Tried replacing the gallery with a blank canvas, and Esc is handled
correctly. I've changed my wizard, adding a ListViewer before the gallery
- this initially has focus & Esc is ok. However tabbing into the gallery
then stops Esc working...

My version of the source is a little old; will try this again once I've
refreshed.
