Changing DiskSuite Tool's Colors and Fonts

By default, DiskSuite Tool uses colors and fonts that are compatible with the OpenWindows^TM desktop applications. This section describes how to change these colors and fonts.

DiskSuite Tool and Colors

DiskSuite Tool uses a variety of colors:

• Standard foreground color - Determines the main colors used to display almost all of the application's elements. The standard background provides the default color for windows, buttons, and other controls.

• Standard background color - Provides the color value used to display information presented in windows, buttons, and other controls.

• Canvas background color - Provides the background color for data areas. For example, the display areas for the Editor, Disk View window, and scrolling lists all use the canvas background color.

• Mapping colors - Display the mappings from logical devices to their slices in the Disk View window. There are eight mapping colors, one for each of the DiskView mappings.

• Status colors - Highlight status information for objects needing attention. There are three status conditions requiring unique colors: Attention, Urgent and Critical.

The X Window System RGB (Red, Green, Blue) color specification mechanism enables you to specify a nearly infinite variety of colors. Of course, many of these colors will appear similar, varying only slightly in shade or intensity.

To aid in selecting and specifying colors, the X Window System provides a standard default set of colors that you can specify by name instead of RGB values. This "database" of color names can be examined using the standard X utility showrgb. It shows the RGB values and a corresponding descriptive alias. For example:

# showrgb
		199  21 133	medium violet red
		176 196 222	light steel blue
		102 139 139	paleturquoise4
		159 121 238	mediumpurple2
		141 182 205	lightskyblue3
		  0 238 118	springgreen2
		255 160 122	light salmon
		154 205  50	yellowgreen
		178  58 238	darkorchid2
		 69 139 116	aquamarine4
...
 		107 107 107	gray42
 		 71  71  71	gray28
 		 61  61  61	gray24
 		255 255 255	white
 		  0 205 205	cyan3
 		  0   0   0	black

You can also examine the default color name database by looking at the /usr/openwin/lib/X11/rgb.txt file.

Unfortunately, there are no standard applications for browsing colors. If you don't have access to a public domain color browser, experiment by trial and error.

DiskSuite Tool and Fonts

DiskSuite Tool uses four different fonts:

• Standard font - Displays almost all text in the tool, for example, in button labels, menus, and dialog boxes.

• Mono-spaced (fixed-width) font - Enables consistent columnar alignment, for example, in the various browsers and scrolling lists. This needs to be specified several times.

• Bold font - Distinguishes attribute names and labels from the actual attribute values. The names/labels in Information windows appear in the standard font and the corresponding values appear in the bold font. This font is used sparingly.

• Small font - Shows the physical devices at the 50 percent scaling level in the Disk View window.

Available Fonts in DiskSuite

The available fonts depend on which X Window System server you use to display the application. The standard X utility, xlsfonts(1), displays the available fonts on a server. For example:

# xlsfonts
--courier-bold-o-normal--0-0-0-0-m-0-iso8859-1
--courier-bold-r-normal--0-0-0-0-m-0-iso8859-1
--courier-medium-o-normal--0-0-0-0-m-0-iso8859-1
--courier-medium-r-normal--0-0-0-0-m-0-iso8859-1
--symbol-medium-r-normal--0-0-0-0-p-0--symbol
-symbol-medium-r-normal--0-0-0-0-p-0-sun-fontspecific
-adobe-courier-bold-i-normal--0-0-0-0-m-0-iso8859-1

Another helpful utility for displaying available fonts is xfontsel(1). Refer to the man pages for these utilities for more information.

DiskSuite Tool's Default Fonts

DiskSuite Tool's default fonts all come from the Lucida font family:

DiskSuite Tool uses the X Window System's resource database mechanism to determine which fonts to use. The default resource specifications are:
