PulldownMenus all have names of the form button_n. The other alternative is to use the more advanced methods of

menu creation that are described in Chapter 15, Menus.

The MainWindow provides a few other resources that control different visual attributes: -XmNshowSeparator,

resources specify the width and height of the MainWindow's margins. Generally, these resources should not be set by

the application, but left to the user to specify. For example:

*XmMainWindow.showSeparator: True
