Chapter 8: X Resources and the Graphical Interface
X Resources and the Graphical Interface
This chapter helps you to understand how to set the X resources that control
the appearance and operation of the debugger's graphical interface. This
chapter:

The debugger's graphical interface is an X Window System application which
means it is a client in the X Window System client-server model.
The X server is a program that controls all access to input devices (typically a
mouse and a keyboard) and all output devices (typically a display screen). It is
an interface between application programs you run on your system and the
system input and output devices.
An X resource is user-definable data
A resource is a user-definable piece of data that controls the operation or
appearance of an X Windows application. A resource may apply to an
application (application-specific resources) or it may apply to the objects
called widgets from which the application is constructed. That is particularly
true of standard widget resources that control the appearance of an
application. For example, most widgets have a standard resource that allows
the user to specify the font used to display text on objects like buttons, menus,
and labels.
An application-specific resource is defined by the application developer and
may control such things as the mode of operation of an application. For
example, you can use an application-specific resource for the debugger's
graphical interface to control whether to start the interface with the command
line on or the command line off.
A resource specification is a name and a value
Each resource in an application has a name and a value. Because an X
Window System application is constructed from widgets, a resource name is
closely associated with the names of the widgets that make up the application.
Each application begins with a top-level widget that is the parent of all other
