QSlider mouse direct jump

Instead of stepping when the user clicks somewhere on the qslider I want to make the slider jump to that position. How can this be implemented ?

Solution

  • Well, I doubt that Qt has a direct function for this purpose.

    Try to use custom widgets. This should work!

    Try the following logic

    class MySlider : public QSlider
{

protected:
  void mousePressEvent ( QMouseEvent * event )
  {
    if (event->button() == Qt::LeftButton)
    {
        if (orientation() == Qt::Vertical)
            setValue(minimum() + ((maximum()-minimum()) * (height()-event->y())) / height() ) ;
        else
            setValue(minimum() + ((maximum()-minimum()) * event->x()) / width() ) ;

        event->accept();
    }
    QSlider::mousePressEvent(event);
  }
};
