    Default Resetting a QSlider with double click

    Hello!

    I have several QSliders scattered around on a quite complex GUI. All of them should be able to reset to 0 when double clicked. Unfortunately QSliders don't have a doubleClicked() signal that I connect to some slot. So what's the best way to implement this?

    Thanks

    QSlider is a QWidget, thus you can use QWidget::mouseDoubleClickEvent(). Simple subclass something like
    Qt Code:
    1. class MySlider : public QSlider
    2. {
    3. protected:
    4. void mouseDoubleClickEvent(QMouseEvent *event);
    5. }
    6.  
    7. MySlider::mouseDoubleClickEvent(QMouseEvent *event)
    8. {
    9. setValue(0);
    10. QSlider::mouseDoubleClickEvent(QMouseEvent *event);
    11. }
    To copy to clipboard, switch view to plain text mode 

    Or install an event filter.
