Greetings Ruby Community: Question: How do I effectively erase a filled rectangle to reveal the RubyTk canvas’ background “color” beneath it? I’m having a tough time trying to "remove’ all traces of the filled widgets that I’ve drawn. Details: I created a TkcRectange on a TkCanvas using a fill option color of, say, ‘antique white’. I then needed to “remove” the rectangle, but when I wrote over it without the fill option specified, thinking that that would “erase” the original rectangle, it didn’t and instead left the first rectangle’s color in place, inferring that the background “color” is transparent. So I have temporarily been using color ‘grey83’ to overwrite my rectangles to get as close as possible to the background grey of the canvas. And, hey, nobody wants to embody their ignorance in code! I am using Ruby 1.8.2 under Windows 2000 Professional. Note: I am new to Ruby, but I have been thumbing through the pickaxe book, and reading through various Ruby web resource pages, (for a few days now, I am almost embarrassed to admit (:\>) ), all to no avail. So far, I have not as yet been able to figure out how I can reveal that oddish grey color of the RubyTk canvas after I write over it with various widgets. Any help or direction on this problem will be greatly appreciated.
