Drawing a Continuous Line with a Mouse with wxPython

I am trying to make a "whiteboard" application in wxPython. I am trying to figure out how to draw a line that follows the mouse when the user is clicking down.

def __init__(self, parent):
    wx.Frame.__init__(self, parent, title="White Board")
    self.Bind(wx.EVT_LIST_BEGIN_DRAG, self.OnDrag)

def OnDrag(self, e):
    print "drag"

The first step is trying to get the mouse coordinates while the user is dragging the mouse, but I am unable to get the word "drag" to print no matter what I do and don't understand why it isn't working.

The mouse event, wx.EVT_MOTION, will give you continuous updates as the mouse moves. Then determine whether the button is down, and also get the X and Y positions, using, say, wx.MouseState.

wx.EVT_LIST_BEGIN_DRAG won't work because: 1) it's a list control event; 2) it only fires when you begin to drag, not the entire time.
