Provides a choice of existing background colors.
When setting background colors, you have four possibilities:
Use the BACKGROUND-COLOUR-NAME attribute and leave the value at DEFAULT (0). The color will then be determined by your color settings in the operating system.
Use the BACKGROUND-COLOUR-NAME attribute and choose from one of the dialog editor's predefined colors. These are represented by the values 1 to 18.
Define your own color by using the BACKGROUND-COLOUR-VALUE attribute in a dialog editor attributes window. To do so, you must first set the BACKGROUND-COLOUR-NAME attribute to CUSTOM (50). A dialog box appears where you can set values for the red, green, and blue elements of your color (RGB model).
Set the color dynamically in event handler code by assigning a value to the attribute.
Note:
Due to consistency constraints imposed by Windows, the specified
setting may not be effective for particular dialog element types, depending on
the version of Windows in use and whether visual themes are enabled.
