How can we create custom slider?
I want to create a slider which contain a custom slider handle and i want to paint it according to slider handle position.
you could subclass QAbstractSlider and do all on your own or derive from QSlider. Just check, how much you have to change...
can we paint some portion of slider and change it according to requirement?
If the docs do notstate it, not.
You could use style sheets for that, there you can change the handle etc.
Also using a custom style would be possible, as all parts of the slider are drawn by the style.
I did something that maybe is also for you.
I subclassed QAbstactSlider and reimplemented paint event to draw a custom handler and a buffer progress under it like when you watch videos on the web.
