Returns a whole number representing an RGB color value.
RGB (red, green, blue)
The RGB function syntax has these named arguments:
|
Part |
Description |
|
red |
Number in the range 0 to 255, inclusive, that represents the red component of the color. |
|
green |
Number in the range 0 to 255, inclusive, that represents the green component of the color. |
|
blue |
Number in the range 0 to 255, inclusive, that represents the blue component of the color. |
Application methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed.
The value for any argument to RGB that exceeds 255 is assumed to be 255.
The following table lists some standard colors and the red, green, and blue values they include:

QBColor Function.
This example shows how the RGB function is used to return a whole number representing an RGB color value. It is used for those application methods and properties that accept a color specification. The object MyObject and its property are used for illustration purposes only. If MyObject does not exist, or if it does not have a Color property, an error occurs.
Red = RGB(255, 0, 0) ' Return the value for Red.= 75 ' Initialize offset.= RGB(I, 64 + I, 128 + I) ' Same as RGB(75, 139, 203)..Color = RGB(255, 0, 0) ' Set the Color property of
' MyObject to Red.
