RGB-VALUE function

Returns an integer that represents a combination of a red, green, and blue color value. This function allows you to define an arbitrary color, expanding beyond those colors defined in the color table.

Note: Does not apply to SpeedScript programming.

Syntax

RGB-VALUE ( redval , greenval , blueval )

redval, greenval, blueval

Identifies red, green, and blue color values which can be combined to define a unique color value.

Example

The following code fragment shows how to set the background color of an ActiveX control:

DEFINE VARIABLE hdlControl AS COM-HANDLE. /* Complete code to get a handle to a control in a control-frame.*/ . . . hdlControl:BackColor = RGB(128, 0, 256).

For detailed information on programming ActiveX Controls, see OpenEdge Development: Programming Interfaces manual.

Note

The RGB-VALUE function is generally most useful when it is used with ActiveX Controls.
