Method AutomationObject():translateColor() Foundation
Translates a COM/ActiveX color value to an Xbase++ color and vice versa
:translateColor( <nColor>, <lIsOLEColor> ) --> nColor
The method returns the translated equivalent to the color value passed. Depending on the value contained in the <lIsCOMColor>parameter, the return either is a COM/ActiveX or an Xbase++ color value.
ActiveX object and controls use a different color format than Xbase++ does. To assign an Xbase++ color value to a COM/ActiveX property, the class method :translateColor() must be used to convert the color before it is assigned to the property. Likewise, if a color value is returned as the return value of a COM/ActiveX method, it must be converted before it can be assigned as the background color for an Xbase Part for example.
The color to be converted is specified in the <nColor> parameter. To translate an Xbase++ color value, the application may pass one of the colors defined in the file GRA.CH (GRA_CLR_xxx), a system color (see XBPSYSCLR_xxx in file XBP.CH), or it may use the GraMakeRGBColor() function to create an RGB-encoded color value. If an Xbase++ color is translated, :translateColor()returns the equivalent COM/ActiveX color value. This value can be used with AutomationObject:setProperty(), for example.
If a COM/ActiveX color value is translated and .T. is passed in parameter <lIsOleColor>, the function returns an Xbase++ color as an RGB-encoded color value. RGB-encoded color values can be used with the Graphics Engine and Xbase Parts. The function GraGetRGBIntensity()can be used to determine the intensities of the individual color guns.
