MacOSX: problem with stucked mouse with modal forms
-
Yes, I know that I can report it to the bugtracker, but just want to know if someone else got this problem. Besides that I'm pretty busy with my job and need some time to create quality example which triggers that bug without huge explanations. Thanks for your answer.

Then, lets try to summarize it: if you open a modal dialog from a modal dialog, the bug triggers ?
-
@SGaist: As i can see it depends how modal window is closed and what it does after closing. This triggers bug every time (thi is how it is my application):
1.Open modal window (w1).
2.Open another modal window from that window (w2) (PrintPreview)
3.Open another modal window from w2 (w3) (My own print dialog)
Now:
If you close w3 on close button -> that's fine - works ok, but if you press button OK some slot which does some operation after closing (eg. put sleep(100) or printing in my case) when button OK is pressed ) then w2 is stucked. App does not respond to mouse clicks.
Escape key is mapped to all forms so I'm closing w2 with Escape. W1 also does not respond to mouse clicks, ok Escape again. Main app window does not respond to clicks also, now by keyboard I start w1 again , and guess what: mouse clicks works. That's why I'm suspicious about QApplicationPrivate::leaveModal_sys(QWidget *widget) which does not reset some internal state, but it's done when QApplicationPrivate::enterModal_sys and qt_modal_stack is created, in case when closed modal form is doing some job before deleting itself.
NOTE: with Qt-4.7.4 (Carbon) everything works fine. -
Sorry, for the late reply
Can you post a minimal code sample to reproduce this ? Just to ensure the same setup is used

Here is example of problem (always reproducible)
http://holobit.homelinux.com:38180/downloads/modalWindowsQtCocoaBug.tar.gzHowto reproduce (best way): start modalWins.app (open modalWins.app or by dbl click in Finder).
Click "Create modal form" button, then click "New dialog", in New dialog form click "New Dialog" , so you have at least 2 dialogs + modal form opened.
Click OK to close dialog. Click OK again to close second dialog.
Now try to click anything in modal form ? Can you ? I guess not.
Ok, now press ESC, so modal form is closed and only QMainWindow is opened. Can you click any button ? No. -

The application itself is not deployed so it won't run.
Anyway, it's reproducible on 10.8.
You should check the "bug report system":http://bugreports.qt.io to see if you find something similar

Yes, something similar is here https://bugreports.qt.io/browse/QTBUG-40585 (I've attached this example here), but there's more similar bugs (3-4 at least) about modal windows on MacOSX.
I hope that someone will fix it before 4.8.7 is out. This really makes Qt 4.8.6 unuseable under mac cocoa. -

You should submit your patch through gerrit and make it reviewed for inclusion in Qt

I know, but first I must make heavy tests for my patch.Already found one more bug, but that bug exists without my patch too ... yes also about modal windows. Now modal windows works, but cannot when I try to close modal window via close button in title bar it does not work.
