Have a look at the following program -
----------------------------------------------------------------------
class MyFrame(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title)
MyPanel(self)
class MyPanel(wx.Panel):
def __init__(self,frame):
wx.Panel.__init__(self,frame,-1)
self.frame = frame
b = wx.Button(self,-1,'Close')
b.Bind(wx.EVT_BUTTON,self.onClose,id=b.GetId())
def onClose(self,evt):
self.frame.Close()
evt.Skip()
class MyApp(wx.App):
def OnInit(self):
frame = MyFrame(None, -1, "Test")
frame.Show(True)
self.SetTopWindow(frame)
return True
app = MyApp(0) # Create an instance of the application class
app.MainLoop() # Tell it to start processing events
----------------------------------------------------------------------
The essential point is that you save a reference to the frame when you
create the panel. Then when the button is clicked you can use the
reference to call the frame's Close method.
