QPushButton Icon opacity/transparency

[d_stranz]

I think you will need to design your icons with an alpha channel. That is how Qt controls transparency. So when you want your button's icon to be transparent, you will either have to change the alpha for the icon or load a new icon with the correct alpha.

Thanks for a quick reply. I have already looked into creating semi-transparent icons for buttons and using that.

Here is what I have done so far. (see attched image) opacity.png

I have created QWidget subclass "ControlButtons" with window opacity set to .3, and when running this widget by itself it semi-transparent. All objects in this widget are transparent including buttons and button icons. But when adding this subclass widget into a parent widget, all opacity settings are lost.

ControlButtons *cb = new ControlButtons(this);
cb->setGeometry(10,10,cb->width(),cb->height());

ControlButtons *cb = new ControlButtons(this);
cb->setGeometry(10,10,cb->width(),cb->height());

To copy to clipboard, switch view to plain text mode 

Is there a way to set opacity to child widget and leave parent widget opacity by default?
