Making a chld widget semi transparent:works ony for full transparency.

[savaliya_ambani]

I am trying to make a child widget a semi-transparent, so that an image set for the parent widget,can be shine through. I mean the parent's image should be dull in the area,where a child occupied.

I have tried using the setStylesheet("background:transparent"); which makes a widget complete transparent. how do i make a child semi transparent on parent widget. Provide me some refrence if possible.

I have gone thorough this http://doc.trolltech.com/qq/qq16-background.html link, but i dont get what to use and which will be the easy way? i am using Qt-4.6.2.

Then set a semitransparent color. Or what exactly do you want?

Thanks.

i have one LCD of 480*800, i have kept an background-image, using setStylesheet on its widget of the LCD Size. Now, i want to put a Child widget. And it's geometry say (100,100,200,200). i should be able to see the parent's semi transparent background-image from this child widget.
Is there Any other way of setting background image on to widget?

I have tried to setStyleSheet("background:transparent"); ,but this shows complete transparent. i want to see slightly dull image . I mean semitransparent child.

And what value semitransparent color poses?

background-color: rgba(255,255,255,60);

background-color: rgba(255,255,255,60);

is a bit of white but one should see the image through.
