[Solved]How to calculate the border-width of a widget in the paintEvent?



  • I have a custom widget for which i have specified the stylesheet as

    @setStyleSheet("border: 5px solid red");@

    which can also be specified in a qss file like

    @#MyWidget
    {
    border: 10px solid red;
    }@

    Since its a QWidget so to make the styleSheet work i added in the paintEvent() fuction of MyWidget

    @void MyWidget::paintEvent(QPaintEvent *e)
    {
    QStyleOption opt;
    opt.init(this);
    QPainter p(this);
    style()->drawPrimitive(QStyle::PE_Widget, &opt, &p, this);
    }@

    The above code has the following output

    How can I calculate/get the border-width in the paintEvent() if the border is specified using stylesheet;



  • After working on this for few hrs i figured out that QWidget does not provide any information about the border-width. So instead of using QWidget i use QFrame.

    My requirement was to paint in the available area excluding the border for a widget.

    This is achieved by using QFrame that provide "frameWidth()":http://doc.qt.nokia.com/4.7-snapshot/qframe.html#frameWidth-prop and "contentsRect()":http:// for the same purpose.

    Thanks.
