Description Milian Wolff 2010-04-14 11:41:40 UTC 
Related to bug 204332 which shows the error in the code completion which is kate-only-code.

This bug also triggers, at least in kde 4.3.4 / Qt 4.5.x, when you request the context menu on the DUChain popup. Afaik I could not reproduce that with KDE 4.4.x / Qt 4.6.x.

The cause for this bug should be the same, i.e. that the context menu get's the focus and hence the popup gets deleted triggering the race.

Imo a quite severe bug, any ideas on how to fix it would be greatly appreciated.
Comment 1 Milian Wolff 2010-04-14 12:25:04 UTC 
Damn I cannot reproduce in valgrind (maybe because everything is too slow then...), but I bet it's the same reason as in the above mentioned kate bug. Here's the GDB bt for now:

Comment 2 Milian Wolff 2010-04-14 12:35:16 UTC 
This would fix the issue, but I find it rather hackisch. Any better ideas?

Comment 3 Andreas Pakulat 2010-04-14 12:44:13 UTC 
How about installing an event filter on all child widgets (in the constructor, or wherever they're added) and eating right-click events in it? That would at least make it clearer why this happens (as opposed to a 3 line hack in some painting-related function).
Comment 4 Andreas Pakulat 2010-04-14 12:45:58 UTC 
Or how about this: Make the tooltip a real widget as soon as the mouse enters. That way a context menu popup would actually work and not try to hide/delete the "tooltip".

PS: Thats what eclipse does and it seems to work pretty well (doesn't get in my way when using the keyboard and is useful when I use the mouse to navigate the tooltip)
Comment 5 David Nolden 2010-04-17 20:10:20 UTC 
I cannot reproduce this here 

It is a real widget. But at some point you have to decide when you hide it again, for example when you switch to another app, and that's the problem here.

I remember that I've fixed this issue by walking the "QObject::parent" chain of the context-menu and see whether it's a child of the tool-tip (see ActiveToolTip::insideThis and ActiveToolTip::eventFilter). We should find out why it doesn't work in some cases.
Comment 6 Milian Wolff 2010-04-17 21:37:37 UTC 
afaik only reproducibly with KDE 4.3 / Qt 4.5 - which we still support in KDevelop 4.0.

But I cannot reproduce with KDE 4.4. / Qt 4.6 - so maybe close nevertheless? I don't want to spent time on fixing it for 4.3 :-/

SVN commit 1115977 by zwabel:

Completely disable the context-menu within the navigation widget. It is completely useless there, and can lead to crashes in the completion-list and navigation-tooltip due to the focus-change.
