QWidget setMask fully transparent.

[bunjee]

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.

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.

The setWindowOpacity is not a suitable solution because I need that behavior.
Then go ahead with setMask. :)
