Providing extra tips on usage

ToolTips are small, transient pop-up windows that are automatically displayed when the mouse cursor is hovered over a window. These popups can be used to provide context-sensitive help messages about what changing the state of a control might do or what a field in a dialog is for. Nearly every control type can have a ToolTip associated with it. This recipe shows how to add ToolTip text to windows in your application.

How to do it…

1. First, let's define a Panel subclass with some controls on it through the following code:

   class MyPanel(wx.Panel):
       def __init__(self, parent):
           super(MyPanel, self).__init__(parent)
   
           self._timer = wx.Timer(self)
           self._countDown = 10
           
           self._msg = wx.StaticText(self, label="")
           self._go = wx.Button(self, label="Go")
           tip = "Start a countdown to exit the application."
           self._go.ToolTipString = tip
           self._stop = wx.Button(self, label="Stop")
           self._stop.Enable(False...
