Chapter 7: Configuring the Debugger
Setting X Resources
Setting X Resources
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 controls an element of appearance or behavior in an X
application. For example, one resource controls the text in action key
pushbuttons as well as the action performed when the pushbutton is clicked.
By modifying resource settings, you can change the appearance or behavior of
certain elements in the graphical interface.
Where resources are defined
When the graphical interface starts up, it reads resource specifications from a
set of configuration files. Resources specifications in later files override those
in earlier files. Files are read in the following order:
1
2
3
4
234
The application defaults file,
$HP64000/lib/X11/app-defaults/HP64_Debug.
The $XAPPLRESDIR/HP64_Debug file. (The XAPPLRESDIR
environment variable defines a directory containing system-wide custom
application defaults.)
The server's RESOURCE_MANAGER property. (The xrdb command
loads user-defined resource specifications into the
RESOURCE_MANAGER property.)
If no RESOURCE_MANAGER property exists, user defined resource
settings are read from the $HOME/.Xdefaults file.
The file named by the XENVIRONMENT environment variable.
If the XENVIRONMENT variable is not set, the $HOME/.Xdefaults-host
file (typically containing resource specifications for a specific remote host)
is read.
