Hey guys,
I want to apply a fully transparent mask to a QWidget.
I tried the following:
setMask(QRect(0, 0, 0, 0)); // Doesn't work
and this:
setMask(QRect(-1, -1, 1, 1)); // Does work
How am I supposed to set a fully transparent mask to a widget ?
Thanks.

Use either full transparent .png image. Or use Qt::transparent. See the docs, this is very easy.
I think full transparent mask is of no use.
Use:
QWidget::setWindowOpacity ( qreal level );

Hi,
I need that behavior on a classic QWidget not a window.

Yes, that was for QWidget only.

Masked widgets receive mouse events only on their visible portions.
The setWindowOpacity is not a suitable solution because I need that behavior.
Thanks anyway.

Then go ahead with setMask. :)
