I solved this by creating a Panel to which I only add 1 element, the
wxCanvas in a boxsizer. In a sense, you can hide the wxCanvas from the
wxPython by adding it to a Panel in this way. No other code needs to
know that the panel contains a pyglet window.
This was useful for other reasons, such as separating the canvas
drawing code from the editor input code: In MainEditorPanel.PostInit()
I bind events on the canvas to callbacks on the panel.
Here is a cut-down version of my code. It doesn't run or anything, but
you could probably compare it to your own. Note that I use XRC
resources for constructing the actual window layout, so just ignore
the PrePanel() and PostCreate() stuff if you are not.
class EditorCanvas(WxCanvas):
def __init__(self, parent, id=-1, config=None, context=None):
canvas.WxCanvas.__init__(self, parent, id, config, context)
def on_draw(self):
pass
def on_resize(self,w2,h2):
pass
def redraw(self):
self.Refresh(True)
class MainEditorPanel(wx.Panel):
def __init__(self):
pre = wx.PrePanel()
self.PostCreate(pre)
self.Bind(wx.EVT_WINDOW_CREATE, self.OnCreate)
def OnCreate(self, event):
self.Unbind(wx.EVT_WINDOW_CREATE)
wx.CallAfter(self._PostInit)
event.Skip()
return True
def _PostInit(self):
# Do all init here
self._canvas = EditorCanvas(self)
self.sizer = wx.BoxSizer()
self.sizer.Add(self._canvas,1,wx.EXPAND)
self.SetSizer(self.sizer)
self.SetAutoLayout(1)
self.sizer.Fit(self)
self._canvas.Bind(wx.EVT_LEFT_DOWN, self.OnLeftDown)
self._canvas.Bind(wx.EVT_MOTION, self.OnMouseMotion)
self._canvas.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow)
self.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown)
