Chapter 17: X Resources and the Graphical User Interface
X Resource Specifications
Class Names or Instance Names Can Be Used
When specifying resource names, you can use either instance names or class names.
For example, a "Done" pushbutton may have an instance name of "done" and a
class name of "XmPushButton". To set the background color for a hypothetical
"Done" pushbutton, you can use:
Application.form.row.done.background: red
Or, you can use:
Application.form.row.XmPushButton.background: red
Applications also have class and instance names. For example, an application may
have an instance name of "applic1" and a class name of "Application". To set the
background color for a hypothetical "Done" pushbutton only in the "applic1"
application, you can use:
applic1.form.row.done.background: red
Note that instance names are more specific than class names. That is, class names
may apply to many instances of the widget.
The class and instance names for the widgets in the Graphical User Interface can be
displayed by choosing Help→X Resource Names and clicking on the "All names"
pushbutton.
Wildcards Can Be Used
A wildcard may be used to match a resource specification to many different
widgets at once. For example, to set the background color of all pushbuttons, you
can use:
Application*XmPushButton.background: red
Note that resource names with wildcards are more general than those without
wildcards.
