# wx.RichMessageDialog¶

Extension of wx.MessageDialog with additional functionality.

This class adds the possibility of using a checkbox (that is especially useful for implementing the “Don’t ask me again” kind of dialogs) and an extra explanatory text which is initially collapsed and not shown to the user but can be expanded to show more information.

Notice that currently the native dialog is used only under MSW when using Vista or later Windows version. Elsewhere, or for older versions of Windows, a generic implementation which is less familiar to the users is used. Because of this it’s recommended to use this class only if you do need its extra functionality and use wx.MessageDialog which does have native implementation under all platforms otherwise. However if you do need to put e.g. a checkbox in a dialog, you should definitely consider using this class instead of using your own custom dialog because it will have much better appearance at least under recent Windows versions.

To use this class, you need to create the dialog object and call ShowCheckBox and/or ShowDetailedText to configure its contents. Other than that, it is used in exactly the same way as wx.MessageDialog and supports all the styles supported by it. In particular, ShowModal return value is the same as for wx.MessageDialog. The only difference is that you need to use IsCheckBoxChecked to examine the checkbox value if you had called ShowCheckBox.

Here is a simple example:

def ShowDialog(self):

if dont_show:
return

dlg = wx.RichMessageDialog(self, "Welcome to my wonderful program!")
dlg.ShowCheckBox("Don't show welcome dialog again")
dlg.ShowModal() # return value ignored as we have "Ok" only anyhow

if dlg.IsCheckBoxChecked():
# ... make sure we won't show it again the next time ...
dont_show = True


New in version 2.9.2.
