Transulcent widget ignore click

rfringuello89

Hi, using QT 4.8 I have 2 windows (2 different QT applications). They are overlapped and the application on top is a QWidget with the attribute @Qt::WA_TranslucentBackground @
I want to make the background of this widget (NOT the children like QPushButtons) transparent to click because I need to interact with the other window which is behind this.

Any suggestion?

Thanks guys ;)

set widget background color using rgba code (255,255,255,0);
where a should be 0 if u want that there should be clicked behind the widget.

otherwise a put 1 to 10 any value.
a represents here opacity

I solved the problem splitting my main widget in several widgets.. in this way I don't need the widget to be transparent in the middle.
Anyway if I try the following in the widget's constructor:

@this->setStyleSheet("QWidget{background:rgba(0,0,0,0);}");@

I only obtain a full black widget and not a transparent widget

I think following properties should be set for making a widget transparent:

setWindowFlags (Qt::FramelessWindowHint);
this->setAttribute(Qt::WA_TranslucentBackground, true);

and one more thing:

It works on windows platform. I m not sure about other platform that it will work or not.
