#920 Focus problem

[Vaclav Kulakovsky]

Focus problem.

Problem is simulated on default config 1.3.8.

1. start icewm
2. open two terminals (ctrl+alt+t , ctrl+alt+t)
3. switch to second desktop (ctrl+alt+2)
4. open one window (ctrl+alt+t)
5. return to first desktop (ctrl+alt+1)
6. switch focus between two windows (alt+tab,alt+tab)
7. switch to desktop 2 (ctrl+alt+2)
8. open new window (ctrl+alt+t)
9. close this window (alt+f4)

now no window on desktop 2 has focus.

I've tried to debug the problem. When window is closing (item 9 above) method YFrameWindow *YFrameWindow::findWindow(int flags) is called from YFrameWindow destructor and it returns currently destroing window (itself).

Several focus bugs have been fixed in the icewm from https://github.com/bbidulock/icewm/
