If I'm not mistaken, in "doRotate" you should be able to refer to the
to-be-closed dialog via
self.frameRotate
Now if you change the "sliderUpdate"-code to store that angle instead of
just letting it fall out of scope, you could access that value through
frameRotate:
def sliderUpdate(self, event):
angle=self.slider.GetValue()
ROTATION_ANGLE=angle
self.angle = angle
self.Destroy()
def doRotate(self,event):
"""Rotating image"""
print self.frameRotate.angle
