Part Identifier Constants

NOT RECOMMENDED WITH THE APPEARANCE MANAGER

When the Appearance Manager is available and you are using standard windows, all the fields of the window color table structure are ignored except the part identifier constant wContentColor in the value field of the ColorSpec structure, which produces the background color for the window's content region.

If you are creating your own custom windows, the window color table structure and all its part identifier constants can still be used.
