| This is a color conversion chart. PowerBuilder help gives the RGB values for the standard 16 colors and then proceeds to take long values as input everywhere in the system.
Using the long values is also faster than using the RGB function, since PowerBuilder does not have to multiply the RGB numbers to calculate the long value. It will also save you a few bytes. Color Red Green Blue Long Black 0 0 0 0 White 255 255 255 16777215 Gray 192 192 192 12632256 Dark Grey 128 128 128 8421504 Red 255 0 0 255 Dark Red 128 0 0 128 Green 0 255 0 65280 Dark Green 0 128 0 32768 Blue 0 0 255 16711680 Dark Blue 0 0 128 8388608 Magenta 255 0 255 16711935 Dark Magenta 128 0 128 8388736 Cyan 0 255 255 16776960 Dark Cyan 0 128 128 8421376 Yellow 255 255 0 65535 Brown 128 128 0 32896 System Colors: Windows Text 2^25 = 33554432 Button Face 2^26 = 67108864 Scrollbar 2^27 = 134217728 Application Workspace 2^28 = 268435456 Transparent 2^29 = 536870912 Windows Background 2^30 = 1073741824 The formula to generate the long value is: (65536 * Blue) + (256 * Green) + (Red) Note on system colors: When you assign a system color to an object and export it, the value is adjusted to your current display properties. Also, not every system color is fully supported by PowerBuilder. ---- [email protected]
