 114 wxPython offers quite a few general purpose dialogs for useful data input from
 115 the user; they are all based on the wx.Dialog class, which you can also subclass
 116 to create custom dialogs to suit your needs.
 117
 118 The Dialog class, in addition to dialog-like behaviors, also supports the full
 119 wxWindows layout featureset, which means that you can incorporate sizers or
 120 layout constraints as needed to achieve the look and feel desired. It even supports
 121 context-sensitive help, which is illustrated in this example.
 122
 123 The example is very simple; in real world situations, a dialog that had input
 124 fields such as this would no doubt be required to deliver those values back to
 125 the calling function. The Dialog class supports data retrieval in this manner.
 126 <b>However, the data must be retrieved prior to the dialog being destroyed.</b>
 127 The example shown here is <i>modal</i>; non-modal dialogs are possible as well.
 128
 129 See the documentation for the <code>Dialog</code> class for more details.
