[PySide] CustomButton alpha image

[Rémi Deletrain]

Hy everybody,

I try to make a customButton with alpha image.

The objectif is to change color of icon from alpha.

I have a code works but I have two probleme...

    - My picture does not have antialiazing, but my painter have flage.

    - It's impossible to scale image.

The code :

def paintEvent(self, qt_event):

        qt_painter = QtGui.QPainter(self)

        

        qt_color = QtGui.QColor(100, 200, 100, 255)

        qt_region = QtGui.QRegion(self._qt_pixmap.mask())

        qt_painter.setClipRegion(qt_region)

        qt_painter.setRenderHint(QtGui.QPainter.Antialiasing)

        qt_painter.setRenderHint(QtGui.QPainter.RenderHint.HighQualityAntialiasing)

        

        qt_painter.fillRect(self.rect(), qt_color)

        qt_painter.end()

My picture has a size 30px.

My widget has a size 90px.

If I set custom rect in "fillRect" nothing change... draw always have 30px 

Anyone have a solution ?
