QDialog with fixed size

[gde23]

Hello,

I've come upon this problem several times:
I have a class that inherits from QDialog and I just want to make it lets say 500x500 pixels in size, no matter on if the widgets on it need that space or not.

I've tried:

• dialog->setFixedSIze();
• dialog->window()-setFixedSize();
• Reimplementing sizeHint() and minimumSizeHint()
• window()->layout()->setSizeConstraint( QLayout::SetFixedSize ); then resize or rezise and then set contraints

nothing works, so what am I missing?

What I used as work around some times it so resize the widgets in the dialog to push it out, but that cannot be the right method.

Hi,

Can you post a minimal compilable sample code that shows the behaviour ?

Which version of Qt are you using ?
On which platform ?

Setting up the minimal example brought me to the solution :)

I had

main_layout->setSizeConstraint(QLayout::SetFixedSize);

in the constructor from copy pasting from another dialog.
Removing it fixed it.

Thanks
