  11
  12     Extension of wxMessageDialog with additional functionality.
  13
  14     This class adds the possibility of using a checkbox (that is especially
  15     useful for implementing the "Don't ask me again" kind of dialogs) and an
  16     extra explanatory text which is initially collapsed and not shown to the
  17     user but can be expanded to show more information.
  18
  19     Notice that currently the native dialog is used only under MSW when using
  20     Vista or later Windows version. Elsewhere, or for older versions of
  21     Windows, a generic implementation which is less familiar to the users is
  22     used. Because of this it's recommended to use this class only if you do
  23     need its extra functionality and use wxMessageDialog which does have native
  24     implementation under all platforms otherwise. However if you do need to put
  25     e.g. a checkbox in a dialog, you should definitely consider using this
  26     class instead of using your own custom dialog because it will have much
  27     better appearance at least under recent Windows versions.
  28
  29     To use this class, you need to create the dialog object and call
  30     ShowCheckBox() and/or ShowDetailedText() to configure its contents.
  31     Other than that, it is used in exactly the same way as wxMessageDialog and
  32     supports all the styles supported by it. In particular, ShowModal() return
  33     value is the same as for wxMessageDialog. The only difference is that you
  34     need to use IsCheckBoxChecked() to examine the checkbox value if you had
  35     called ShowCheckBox().
  36
  37     Here is a simple example:
  38     @code
  39     void MyFrame::ShowDialog()
  40     {
  41         if ( ... shouldn't show this dialog again ... )
  42             return;
  43
  44         wxRichMessageDialog dlg(this, "Welcome to my wonderful program!");
  45         dlg.ShowCheckBox("Don't show welcome dialog again");
  46         dlg.ShowModal(); // return value ignored as we have "Ok" only anyhow
  47
  48         if ( dlg.IsCheckBoxChecked() )
  49             ... make sure we won't show it again the next time ...
  50     }
  51     @endcode
