There are a number of ways to handle this. You could just bind the
parent to the handler. Something like this:
self.Bind(wx.EVT_BUTTON, self.onStop)
This will bind all button presses to the onStop handler. You could
also do something like this:
self.Bind(wx.EVT_BUTTON, self.onBtnStop)
def onBtnStop(self, event):
#do something
event.Skip()
By calling the Skip() method, it will propagate the event and look for
another handler, which in this case would be the onStop handler. On
Windows, you will most likely need to make a wx.Panel be the parent of
the rest of the widgets to have this effect.
My complete test code is below.
<code>
import wx
class Closer(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, title='Test Frame')
panel = wx.Panel(self, -1)
sizer = wx.BoxSizer(wx.VERTICAL)
btn1 = wx.Button(panel, wx.ID_ANY, 'Button 1')
btn2 = wx.Button(panel, wx.ID_ANY, 'Button 2')
btn3 = wx.Button(panel, wx.ID_ANY, 'Button 3')
sizer.Add(btn1)
sizer.Add(btn2)
sizer.Add(btn3)
self.Bind(wx.EVT_BUTTON, self.onDone)
self.Bind(wx.EVT_BUTTON, self.onStop, btn1)
panel.SetSizer(sizer)
def onStop(self, event):
print 'Stop!'
event.Skip()
def onDone(self, event):
print 'Done!'
if __name__ == '__main__':
app = wx.PySimpleApp()
Closer().Show()
app.MainLoop()
</code>
FYI: There is an excellent wxPython group that you can join over on
the wxPython.org website.
