: value sets the current resource to value. Since most resources have mixed case, you should enclose any resource name in quotes. Resource names are the Motif names with the XmN prefix removed. Some resources can only be set before the widget is created. For efficiency, set as many resources as you can before creation.
scalar_value? returns the value of the current resource whose type is integer.
string_value? returns the value of the current resource whose type is string.
pointer_value? returns the value of the current resource whose type is a pointer of any kind.
create! creates an instance of the widget. Any resources that have been specified prior to the create! will be set. An id? message also sends a create!.
on! realizes the widget. Realizing a widget creates its windows and displays it when it is managed.
