109overview = """\
110wxPython offers quite a few general purpose dialogs for useful data input from
111the user; they are all based on the wx.Dialog class, which you can also subclass
112to create custom dialogs to suit your needs.
113
114The Dialog class, in addition to dialog-like behaviors, also supports the full
115wxWindows layout featureset, which means that you can incorporate sizers or
116layout constraints as needed to achieve the look and feel desired. It even supports
117context-sensitive help, which is illustrated in this example.
118
119The example is very simple; in real world situations, a dialog that had input
120fields such as this would no doubt be required to deliver those values back to
121the calling function. The Dialog class supports data retrieval in this manner.
122<b>However, the data must be retrieved prior to the dialog being destroyed.</b>
123The example shown here is <i>modal</i>; non-modal dialogs are possible as well.
124
125See the documentation for the <code>Dialog</code> class for more details.
