How do you instantiate the message boxes? It seems as your are creating modeless message boxes instead of modal ones.

Why do you use this way at all? Just use breakpoints for your debugger to step through your code.

You have to use mode dialogs to block the ui thread. However, I would use a real debugger or a qDebug() set of messages instead of that boring technique.

If you really want to do it this way, use the static functions API of QMessageBox. They are easy to use and block until the box is dismissed.

sums up,

1. Try the debug tools like dbx on unix,gdb on linux first
2. Try qDebug(”(%s,%d), your debug message”, FILE, LINE); or std::cout….
3. use QMessageBox::information(NULL, “Debug Information”, QString(”%1,$2…Your debug message”).arg().arg()…);

Thank you all for the replies. Will be trying the style I wanted initially and then probably break points followed by qDebug.

Cheers
