Prevent QDialog from hiding

krzysieklfc

Hello,

How can I prevent QWidget::hide from being called from within done? I want to implement fade in/out animation when the widget is created/destroyed, and right now it's being hidden immediately.

void QDialog::done(int r)
{
    Q_D(QDialog);
    d->hide(r);
    d->finalize(r, r);
}

Hi
It's virtual so you can just override it.

@mrjj Thanks. Also I had to override QDialog::open instead of overriding QDialog::exec, otherwise it wouldn't return until hide is called.

Hi
Thanks you for updating.
What will you use for the animation? (if i may ask)
Q animation classes and setWindowOpacity ?
There is also QGraphicsOpacityEffect.

@mrjj I'm using QPropertyAnimation on a windowOpacity property.
I shared the code in the answer here. I also added dark overlay effect.
