Hello Eric

Sorry, I don't have time right now to test this, but you might. Does it 
send the event when selecting via Shitf+Right/Left Arrow?

It *could* be related to the post selection feature, but not sure (in that 
case I would expect that Shift+Right/Left Arrow also doesn't send the 
event). Someone would have to debug this and figure out whether it is the 
intended behavior or simply a bug.

Please cc me if you open a bug report.

Dani

events
Sent by:        platform-dev-boun...@eclipse.org



Hello,

I am not sure about certain behaviour in the Eclipse Java editor so I am 
writing to this list for clarification.

I am dealing with an issue where StyledText is not sending SWT.Selection 
events when doing selecting text in a certain way while using the 
Eclipse Java editor. Specifically, StyledText.sendSelectionEvent() is 
not being triggered.

For example:
1) Open any Java file in the IDE
2) Press Ctrl + Home
3) Press Shift + End

This will select an entire line, but StyledText.sendSelectionEvent() is 
not called. If I hit the down arrow (moving the caret one line down and 
clearing the selection), I see the method being called. But doing Shift 
+ End on any line is not triggering it at all.

Is this expected behaviour? Using pure SWT StyledText snippets shows 
that Shift + End is indeed triggering the sendSelectionEvent() method, 
but for some reason the Eclipse Java editor is not doing that.

Thoughts?
