COLOR CONSTANTS
apXXXX
Application palette constants.
These constants select the active application-level color palette. The selected value is stored in $appPalette and determines how logical color roles are mapped to actual screen attributes.
Constant Value Usage
apColor 0 Selects the color screen palette
apBlackWhite 1 Selects the black and white palette
apMonoChrome 2 Selects the monochrome screen palettecpXXXX
Color Palette constants
Except for cpColor, cpBlackWhite and cpMonoChrome, all of the color palette constants contain indices into their owner's palette. For cpColor, cpBlackWhite and cpMonoChrome, each entry contains an actual BIOS video color attribute byte.
You can use these color palette maps to determine what color a particular object or component will have when it appears on the screen. For example, if you place a TButton object into a TDialog object, you can trace through the color palettes to determine what color it will have. A normal button will have the attribute Text Normal shown in the first byte of the cpButton color palette. This color entry is an index into its owner's palette, cpDialog. Looking at the 10th entry of cpDialog, we see that this maps to entry 41 in the application-level palette. In the case of cpColor (color display in use), this corresponds to black lettering on a green background.
