[Iup-users] IupMatSetAttribute

[Merick]

How do I change the background color of a matrix cell?

color_mat = iup.matrix{numcol=8, numlin=32, numcol_visible=8, 
numlin_visible=8, widthdef=5, alignment = "ACENTER"}
iup.matsetattribute (color_mat, "BGCOLOR", 1,1, "255 255 255")

Basically, what I'm trying to do is use the matrix as a custom color 
palette with the callbacks set so that a left click will insert the 
color codes into text buffer, and a right click will open the built-in 
color selector to let the user edit the color for that cell
