Augmenting the basic layout

The creation of the layout is again deferred to a method called augment_layout. We keep the layout as simple as possible. We create a panel for the acquired video frame and draw a row of buttons below it.

The idea is to then click one of the six radio buttons to indicate which facial expression you are trying to record, then place your head within the bounding box, and click the Take Snapshot button.

So, let's have a look at how to build the six buttons, and correctly place them on a wx.Panel object. The code for this is shown in the following block:

    def augment_layout(self):        pnl2 = wx.Panel(self, -1)        self.neutral = wx.RadioButton(pnl2, -1, 'neutral', (10, 10),                                      style=wx.RB_GROUP) self.happy = wx.RadioButton(pnl2, ...
