29.21 X Resources

Function: x-get-resource attribute class &optional component subclass

The function x-get-resource retrieves a resource value from the X Windows defaults database.

Resources are indexed by a combination of a key and a class. This function searches using a key of the form `instance.attribute' (where instance is the name under which Emacs was invoked), and using `Emacs.class' as the class.

The optional arguments component and subclass add to the key and the class, respectively. You must specify both of them or neither. If you specify them, the key is `instance.component.attribute', and the class is `Emacs.class.subclass'.

Variable: x-resource-class

This variable specifies the application name that x-get-resource should look up. The default value is "Emacs". You can examine X resources for application names other than "Emacs" by binding this variable to some other string, around a call to x-get-resource.

See section `X Resources' in The GNU Emacs Manual.
