FocusIn/Out on Composites [message #1219914]

I have some complex composites that I would like to include in the tab sequence e.g.

Text1
Button
Text2
ScrolledComposite
--- CompositeLvl1
--- --- CompositeLvl2
--- --- --- Label
--- --- --- Label
--- --- CompositeLvl2
--- --- --- Label
--- --- --- Label

I am happy for the CompositeLvl1 to be in the tab sequence, then once this has focus, I will use key listeners to navigate through the Lvl2 Composites using arrow keys.

So, the TAB sequence would simply be Text1->Button->Text2->CompositeLvl1.

ScrolledComposite is included in the Shell's TabList. CompositeLvl1 is included in the ScrolledComposite's TabList. All CompositeLvl2s are included in CompositeLvl1's TabList. All child Labels are included in their owning CompositeLvl2's TabList... i.e. everything has all its direct children defined in their TabLists!

The strucutre is much like a Grid where the Lvl2 Composites are cells in the grid.

I have this working ok in SWT by placing FocusIn and FocusOut listeners on CompositeLvl1, as well as a KeyDown.

However, in RAP, I don't seem to get any FocusIn/FocusOut events triggered on CompositeLvl1... is this because those types of events simply are not implemented in RAP, or is it possible I've found a bug?

Didn't want to waste huge amounts of time on this if only to discover that FocusIn/FocusOut are not available in RAP!

Thanks, John

Hi John,
focus listeners are working fine in RAP. Are you sure that focus in/out
events are fired on Composite in SWT? I think that Composite is a
non-focusable control.
Best,
Ivan
