 |
|
Is it possible for TColorBox to return selected colors as RGB numberic
values instead of clBlack etc, so ofcourse for black it would be
0.0,0.0,0.0
also can i set a custom defined selection of colors at design or
runtime for the user to select ??
any help appreciated

I'm not sure what you mean by that.
TColorBox::Selected returns a TColor and TColor is just an enunmerated
type defined as:
enum TColor {clMin=-0x7fffffff-1, clMax=0x7fffffff};
That is to say it takes any numeric value in that range. 'clBlack' is
just a convenient constant that at compile time gets converted into a
numeric value in the above range.
If you want to allow the user to select any colour then set Style to
'cbCustomColor'.
If you want to convert a TColor to RGB values use ColorToRGB()

Have a look at the ColorToRGB() function.
