Appendix D. User Interface Configuration

Data Explorer provides its own set of resources for customizing the user interface in addition to the standard X-window and Motif resources. These resources (see table) can be specified in the .Xdefaults resource file, and a majority can be invoked as command line switches or options. For example:

DX*noImagePrinting: true
DX*restrictionLevel: maximum

dx -image -noImagePrinting -restrictionLevel maximum

The command line switch for a Boolean resource (e.g., -noImagePrinting) toggles the default value.
