colors in pixmap

[Marco Lettere <lettere di unipi it>]

hello everyone,

suppose I've a pixmap with a color which I want to modify with 3 slider
widgets for RGB.
The way I'm performing it now is to destroy the old pixmap, change the xpm
C structure and then recreate the pixmap with the new data.
Isn't there a better way (less expensive) of performing this operation
I'm thinking about something like

gtk_pixmap_update_color(Gtkpixmap* pix,int colorIndex,GdkColor* newColor);

thanx,
M.
