status bar question

Still fooling around with sample code to see how wx works.

I've created a panel by subclassing wx.Panel. The panel is populated
with various controls that trigger events. The events are handled in
methods that are members of my panel subclass.

Then I instantiate a new app. I create a frame and call the frame's
CreateStatusBar() method.

Question: how do I pass text info from the panel's event handler methods
to the frame's status bar?

Thanks in advance!

Here's some code:

class Form1(wx.Panel):
  def __init__(self, parent, id):
    wx.Panel.__init__(self, parent, id)

    # button
    self.button = wx.Button(self, 10, "Save", wx.Point(200, 325))
    wx.EVT_BUTTON(self, 10, self.OnClick)

  def OnClick(self,event):
    self.logger.AppendText(" Click on object with Id %d\n" %event.GetId())
    
    # --> this doesn't work <--
    sbar = wx.StatusBar(None)
    sbar.SetStatusText('EvtRadioBox: %d\n' % event.GetInt())

app = wx.PySimpleApp()

# set frame parent, id, title, pos, size
frame = wx.Frame(None, -1, "Our first control", wx.Point(200, 100), wx.Size(600, 400))
frame.CreateStatusBar()

# add panel, Form1, to frame
Form1(frame, -1)

# show frame & run main loop
frame.Show(1)
app.MainLoop()
