[cdt-dev] React on debug view visibility changes

[Raphael Zulliger <zulliger@xxxxxxxx>]

Hi

I should probably ask this question in a different Eclipse list, but I 
thought to ask here first because someone of you guys may have come up 
with a solution for the following problem already.

Background information: I'm developing some plugins that extend CDT/DSF 
to deal with a slightly customized GDB version (suitable for our own 
hardware).

The simple question: When debugging, I need to be aware of which tasks 
are 'expanded' in the debug view. Or, in other words, which stack frames 
are visible in the debug view. More precisely: I need to get notified 
whenever the stack frames are either expanded or collapsed. How can I do 
that?

I tried to find a way of doing what I need, but did not come up with a 
usable solution. According to my investigation:
 - There is no CDT support for getting notified whenever the stack 
frame visibility changes
 - There is no special support from Eclipse to get notified about the 
visibility of elements in the debug view (IDebugUIConstants.ID_DEBUG_VIEW)
 - There *is* a possibility to get notified about TreeExpansionEvent 
(treeExpanded and treeCollapsed) events. BUT: these events are not 
generated when the tree gets expanded programmatically (which is done by 
DSF upon certain thread-events (such as breakpoint hit)).

Again, my question: Is anybody out there who had to be aware of such 
'visibility events' in the past and who could give me some hints? Any 
ideas about a possible solution? Would it be better to ask the Eclipse 
folks which are responsible for the debug view?


Any input would be highly appreciated.

Thanks,
Raphael
