Hi, I am new to ltk and am trying to create rectangles of different colors on a canvas. I would like to specify the value of the :fill option with a variable for example (itemconfigure canvas rectangle :fill :some-var-val) , but I am not sure how to do that; any help would be greatly appreciated. Also what are the acceptable formats for specifying a color? I know there are words like 'red' and 'black' and there is also hexadecimal #RRBBGG are there others? Thanks again. -Irvin H.
