The Choice control is a means to allow the user to make a single selection from a list of possible selections. It does this by displaying the currently-selected choice and offering the list of other possible choices in a pop-up when the control is clicked on by the user. This makes it very efficient in its use of screen space.
To see how the Choice control works, we will make a simple Panel that has a Choice control with three choices in it:
class ChoicePanel(wx.Panel):
def __init__(self, parent):
super(ChoicePanel, self).__init__(parent)

sizer.Add(self.choice, 1,
wx.EXPAND|wx.ALL, 20)
self.SetSizer(sizer)
# Event Handlers
self.Bind(wx.EVT_CHOICE, self.OnChoice)
