Syntax

Visual Basic (Declaration)

expression.GetBackgroundColorAsInt( _
   ByVal attr As TextColorMappingAttribute _
) As Integer

where expression is a variable that represents a ThemeColor Object

Return Value

The integer value that the background color of the specified attribute is mapped to in the color map.

Remarks

In Open Systems sessions, screen colors are mapped to integer values in a color map. Although you can select from only one of 16 colors, you can change the actual screen colors to any RGB values by changing the RGB values of the color map.

For example, if the screen foreground color of normal text is mapped to 0 in the map (which has a default color of Black), you can change the default RGB value mapped to 0 to another RGB value.

You can use this approach to change the actual screen foreground and background colors to any RGB colors. Use this method to get the integer value the background color is mapped to. Then use the SetColorRGB Method method to change that color to any RGB value.

You can view the theme color map in the user interface by clicking Color Map, under Text Color Mapping in the Modify Theme dialog box.

The default color mapped to each integer value is shown below.
