[Pythoncard-users] fullscreen on monitor 2?

I'm trying to open a child window as fullscreen on monitor 2. I'm able
to launch a child window on monitor 2, and I'm able to go fullscreen
on monitor 1, but not fullscreen on monitor 2.

Here's the code I'm using to launch a child window on monitor 2:

import minimal
self.viewerWindow = model.childWindow(self, minimal.Minimal)

# 0 is monitor one, 1 is monitor two
display = wx.Display(1)
geometry = display.GetGeometry()

w, h = geometry.GetSize()
self.viewerWindow.size = (w, h)

x = geometry[0]
y = geometry[1]
self.viewerWindow.position = (x, y)


Adding this line makes it go fullscreen, but only on monitor 1:

self.ShowFullScreen(True)

Does anyone have any tricks to make it go fullscreen on monitor 2?
