load gif into QMovie object from data (no file)

Question

I have read through many questions, most of which not on this site, and they all mention QMovie must be called with a file name, like this

anim = QtGui.QMovie(\"         


        

Answer 1

The QMovie constructor can take a QIODevice as first argument, so the gif data can be loaded via a QBuffer:

a = QtCore.QByteArray(data)
b = QtCore.QBuffer(a)
b.open(QtCore.QIODevice.ReadOnly)
m = QtGui.QMovie(b, 'GIF')
