How to animated QProgressbar

[Toocold]

When I draw the PrimitiveElement PE_IndicatorProgressChunk, I want to use QMovie to play a gif/webp. What should I do?

@Toocold Can you please explain better?
In the title you write you want to animate QProgressBar, but then you're talking about QMovie.
So, what do you want to do?

@jsulm I want the PE_IndicatorProgressChunk is a animation, like QMovie or QPropertyAnimation. Qt had implemented a animated QProgressbar in windowsvista QStyle(The ProgressChunk has a streaming light animatin), I want to implement it in my custom QStyle.
