Mosaic User's Guide

# Setting X Resources

X resources are usually set in a personal `.Xdefaults` file (in the user's home directory). Since the class name for the Mosaic application is Mosaic (with a capital M), entries in an `.Xdefaults` file look something like this:

      Mosaic*defaultHeight: 700
      Mosaic*fancySelections:  True
      Mosaic*personalAnnotationDirectory: misc/.mosaic-personal-annotations
      Mosaic*visitedAnchorColor: red

Note that if you alter your `.Xdefaults` file while Mosaic is running, the changes will not take effect until you quit and re-run Mosaic. On most systems, you also need to use the command:

      xrdb .Xdefaults

to cause the `.Xdefaults` file to take effect.

You will notice that this documentation describes X resources by their name, followed by a colon (:), followed by the resource data type. For example, if the resource type is integer, then the word integer should be replaced by a whole number. Here is a brief list of resource data types:

integer
  A whole number, for example:
  Mosaic*defaultHeight: 700
Boolean
  Either True or False, for example:
  Mosaic*fancySelections: True
string
  A character string, for example:
  Mosaic*personalAnnotationDirectory: misc/.mosaic-personal-annotations
color
  The name (or number) of a color, for example:
  Mosaic*visitedAnchorColor: red
  Mosaic*Foreground: #000000000000
font
  The name of a font, see example `.Xdefaults` file for examples.

For more help, see this example `.Xdefaults file.`
