HELP SHOWPALETTE                      Chris Thornton, May 25  1994


This procedure can be used to set up interactive colour palettes under X
on a colour screen.

   showpalette('mypalette')

This will set up a default palette called 'mypalette' and return a
one-element vector. This vector always contains the current, selected
colour. To select colours from the palette you click on them, usually
with the left mouse button. The colour and its name or RGB value are
then shown in the selection area at the bottom of the palette. To
unselect a colour you click on it where it appears in the selection
area. To redisplay the palette (eg. after resizing its window) click
close to the bottom, right corner of the window.

   showpalette('mypalette', [red green blue pink])

This will set up a palette showing the specified colours and return a
one-element vector which always contains the current selection.

   showpalette('mypalette', [red green blue pink], 3)

This will set up a palette showing the specified colours and return a
three-element vector which always contains the current selections.

   showpalette('mypalette', [red yellow blue pink], {red blue})

This will set up a palette showing the specified colours and return a
two-element vector which always contains the current selections and
which is initialised to contain `red' and `blue'.
