QLineEdit cursor lost when switching between layouts

[missoni]

Hello!

Programming with Qt 4.7.0 under Windows, I came across a very strange problem that i cannot solve. The code has now grown so big, that i cannot find the guilty excerpt to upload it here.

In my program, I allow the user to work with "projects". Each project consists of a few stages (compare to Adobe Lightroom, e.g.). I emulate switching between stages by changing program layout each times a user chages current stage. To the left of the program QMainWindow is the panel with stage buttons, to the right - the corresponding stage layout.

At the beginning everything works just fine. Now, when i switch between stages 2 and 1 qlineedits lose focus (?) and i cannot click them with my mouse any more. I can, however, access these QLineEdits with the TAB-key. The problem seems to be in that layout of stage 1 loses track of mouse cursor.

Does anybody have an idea what could be wrong?

Thank you!

Hello!

I'm afraid too big is not an option. You will have to do better than that and track your problem.

I would suggest, to temporarily put ALL your signal connections into comments and see if the problem still persists.

And rebuild your project and run qmake.

Good luck!
