Hello,
I have a problem reported by my MAC/OS testers with the brand new 530
official release. As it seems, there is a problem with
QMessageBox::show() which seems to be blocking eventLoop.
The sequence is like that:
qWarning()<<"step 1";
waitBox = new
QMessageBox(QMessageBox::Information,tr("testing"),
tr("Please wait..."));
qWarning()<<"step 2";
waitBox->setStandardButtons(QMessageBox::NoButton);
qWarning()<<"step 3";
waitBox->show();
qWarning()<<"step 4";
QApplication::processEvents();
qWarning()<<"step 5";
parent->getMainWindow()->stopTimer();
qWarning()<<"step 6";
If I run this under 530/MacOS, I see only up to "step 4" in the console.
If I remove processEvents() it continues, but I have problems later for
instance doing deleteLater() which never calls the destructor. As it
seems to me the event loop is locked.
Note that if I remove
waitBox->setStandardButtons(QMessageBox::NoButton);
and actually clicks on the OK button, then all is doing fine... If I
don't click I stay locked on the step 4, a bit like if I was using
exec() instead of show().
Under 521/Mac no problems with the same sequence. Under other platforms
and latest 530 no problem so far, so the case seems related to mac
release.
Can anyone confirm this?
