HighQualityAntialiasing

[blanchoir]

When drawing a rounded rectangle then applying it as the windows shape using


def resizeEvent(self, event):
pixmap = QtGui.QPixmap(self.size())
pixmap.fill(QtCore.Qt.transparent)
painter = QtGui.QPainter(pixmap)
painter.setBrush(QtCore.Qt.black)
painter.drawRoundedRect(pixmap.rect(), 8, 8)
painter.end()

self.setMask(pixmap.mask())

It comes out very poor quality, and it seems that I should be using OPENGl or is there is a way to have it set to HighQualityAntialiasing

You can set antialiasing modes in the painter. Check the documentation.
