Can't move and resize QDialog
-
I have a BaseClass derived from QDialog and a ChildClass derived from BaseClass.
I create an instance of ChildClass und call child.exec();
In the BaseClass I override the showEvent. There I call:
this->setGeometry(QRect(20, 20, 200, 200)); QDialog::showEvent(event);I can do what ever I want, the Dialog shows always maximized.
I'm completely stumped.
What is wrong with the code? -
Hi,
What version of Qt ?
On what platform ?
Why are you setting the geometry inshowEvent?
What else are you doing with that dialog ? -

showEvent?What do you mean, is this no good idea to do it there?

It is a simply information dialog for the user, such like a message box. It is not necessary to show it as a maximized (full screen) window

Based on Qt 5.11.1 (Clang 8.0 (Apple), 64 bit)That's the version of Qt used to build Qt Creator not the one you are using to build your application.
While the QtWidgets module can be used on iOS, it's not designed for it. You will have better results with QtQuick.
That said, why are you setting the geometry of the dialog ? They usually handle their size pretty well.
