QSlider mouse direct jump

Question

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 ?

Answer 1

Here is a simple implementation in python using QStyle.sliderValueFromPosition():

class JumpSlider(QtGui.QSlider):

    def mousePressEvent(self, ev):
        """ Jump to click position """
        self.setValue(QtGui.QStyle.sliderValueFromPosition(self.minimum(), self.maximum(), ev.x(), self.width()))

    def mouseMoveEvent(self, ev):
        """ Jump to pointer position while moving """
        self.setValue(QtGui.QStyle.sliderValueFromPosition(self.minimum(), self.maximum(), ev.x(), self.width()))
