QApplication::activeWindow() working incorrectly

[iddqd 0]

Hello everyone!

QMessageBox::information(QApplication::activeWindow(),"Error",
                    query.lastError().text(),QMessageBox::Ok);

When I use this construct, the QMESSAGEBOX returns an empty one with no message. The message is sent from another class that does not have widgets.

QMESSAGEBOX returns an empty one with no message

What does this mean?

@iddqd-0 What happens if you don't set parent? Setting parent or not should not have any influence on the content of the message box. What does query.lastError().text() return?

@Christian-Ehrlicher
instead of a window with an error message, I get just an empty window

What Qt version do you use? Is this called from the main thread?

@Christian-Ehrlicher I'm using version 6.0.2. Yes, in main thread

Ok, fine. Can you create a minimal example to reproduce the problem? It looks like a QMessageBox in main() should also trigger your issue.
