Colours may be created from their X11 names. The X11 name-table is in
<pcehome>/lib/rgb.txt
. In the Windows API,
all colours described as RGB (Red, Green,
Blue) tuples. This is no problem as XPCE also
provides RGB colours. Note however that Win32 intensity is ranged
0..255, where the XPCE intensity is ranged
0..65535. This is true on all XPCE's platforms.
To provide access to the window-system colours as they can be
obtained using the Win32 API function GetSysColor(), XPCE
binds these colours to named colour objects. These colour objects are
normally used in the XPCE resource file (<pcehome>/Defaults
)
to colour
XPCE's controller objects according to the user's
preferences.
If the name of the Windows API colours are COLOR_SOMETHING, the XPCE
name is win_something
. The full list is in table
10.
