Hello,
I wonder if there is an easy way to convert a 6-digit HEX RGB value String
to TColor?
Thanks in advance,
SZ

AnsiString HexColor = "0x99DDFF";
TColor C = (TColor)HexColor.ToIntDef(0);

Re:Converting Hex to TColor

Hello,
Thanks for the reply but the below code does not work here. I enter
"0xFF0000" which should be red but the colordialog displays blue! When I
append "00" more, (making the string "0xFF000000") it displays pink.
Regards,
SZ

As it should be.
The hexadecimal value is so formed: 0xBBGGRR.
Where BB = blue, GG = green and RR = red.
If it doesn't work for you, please show your actual code.

Re:Converting Hex to TColor

Ok. So what confused me was it being bbggrr istead of rrggbb the usual way.
;(
Thanks a lot!

Re:Converting Hex to TColor

I suppose that you know for the functions:
ColorToString()
StringToColor()
...which handles both descriptive (clRed) and value
based colors ("0xbbggrr00")
