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