PowerBuilder Colors

RGB

Deriving RGB values. The formula for combining primary color values into a number is:

256*256*blue + 256*green + red = number

where the amount of each primary color is specified as a value from 0 to 255. For example, to specify cyan, substitute 255 for blue, 255 for green, and 0 for red. The result is 16776960.

The table below lists the blue, green, and red values you can use in the formula to specify other colors.

Blue	Green	Red	Number	Color
0	0	255	255	Red
0	255	0	65280	Green
0	128	255	32768	Dark Green
255	0	0	16711680	Blue
0	255	255	65535	Yellow
0	128	128	328896	Brown
255	255	0	16776960	Cyan
192	192	192	12632256	Light gray
255	255	192		Pale yellow
100	100	100		Dark Gray

System Colors

The current frameworks have a data color service to fetch the various system colors. To make use of this, call inv_datacolors.

long ll_selected_text

IF NOT IsValid(gnv_cst_app_object.inv_datacolors) THEN
   gnv_cst_app_object.of_SetDataColors(True)
END IF

ll_selected_text = gnv_cst_app_object.inv_datacolors.of_SelectedColor()
this.textcolor = ll_selected_text

The function calls are:

• gnv_cst_app_object.inv_datacolors.of_SelectedColor( ) // Selected background
• gnv_cst_app_object.inv_datacolors.of_EnterableColor( ) // window text
• gnv_cst_app_object.inv_datacolors.of_ReadOnlyColor( ) // buttonface
• gnv_cst_app_object.inv_datacolors.of_SelectedTextColor // Selected text color

You can also hard code an RGB like value for various system colors. These are handy for using in datawindow expressions. Sorry, no Selected or Selected Text colors that I am aware of.
