[Qt-interest] Modal Question Dialogs in event handler?

[Malyushytsky, Alex]

I have not had such problems, but I did not have slots with message box connected to QTabWidget::currentChanged signal.
I would be surprised if it was a problem though. Problem is mostly likely in the other code you executing in your slot.
You can try to use Qt::QueuedConnection in your connect, so your slot is called after all current events are handled.

Subject: [Qt-interest] Modal Question Dialogs in event handler?

Hello All,

I was wondering if anyone knows of any issues with showing a modal QMessageBox::question dialog from within an event handler (slot). I have a slot that is responding to the QTabWidget::currentChanged signal and when I show the QMessageBox::question dialog the widgets in the QTabWIdget all disappear. Then when I close the dialog and hover over the widgets they reappear as I hover over each one. As soon as I click on a tab in the QTabWidget, the application crashes. Does anyone know if there is a known issue with this? Or has anyone experienced any similar problems?

Thank You,
Eric
