The 'color' properties of controls remember whether you set them to a
named color, or to an RGB triple.
what is the point of the 'effective' in
effective backgroundColor
If a control's *color property is empty it will inherit from the first
non-empty ancestor. Using effective means you see the concrete value.
e.g.
group 1 -- backgroundColor == red
field 1 -- empty backgroundColor
put the backgroundColor of field 1 -- empty
put the backgroundColor of group 1 -- red
put the effective backgroundColor of field 1 -- red
Um: set the backgroundPixel of someObject to the backgroundPixel of
someObject
boy-O-boy: was somebody feeling bloody-minded the day that 'thing' was
implemented :)
Getting the backgroundPixel will encode any named color as RGB values,
and setting the backgroundPixel will end up setting the backgroundColor
to a non-named color with the derived RGB tripe - which is why you can
use that line of code to convert named colors to their RGB counterparts.
Of course, one could argue there should be a more obvious way :)
Warmest Regards,
Mark.
