[wxPython-users] (Yet another) sizer question

It may be an overkill but, if you handle the wx.EVT_SIZE of your frame (calling event.Skip() at the end!!!) and the EVT_MOVE and you store the position and the size of your frame, you may be able to detect which action the user has done. For example:

def OnSize(self, event):

	newpos = self.GetPosition()
	newsize = self.GetSize()

	if newsize.x == self.storedsize.x:  # nothing changed in x
		event.Skip()
		return

	if self.storedposition.x == newpos.x:
		if newsize.x > self.storedsize.x:
			# user has dragged the right hand border
			# and the frame is bigger
		elif newsize.x < self.storedsize.x:
			# user has dragged the right hand border
			# and the frame is smaller
	elif self.storedposition.x < newpos.x:
		if newsize.x > self.storedsize.x:
			# user has dragged the left hand border
			# and the frame is bigger
	else:
		if newsize.x < self.storedsize.x:
			# user has dragged the left hand border
			# and the frame is smaller

	self.storedsize = newsize
	self.storedposition = position

	event.Skip()


def OnMove(self, event):

	self.storedposition = event.GetPosition()
	event.Skip()


You may want to triple-check (quadruple or more) what I have wrote, I have not tested it and there may be some other case missing in the if switches. I am not sure it will work, but you can try it ;-)

Andrea.
