Perl/Tk saves your favourite tools

One of the most important widgets is the Canvas, which is used to draw on just like the canvas of a painting.

By the way:

   $canvas->createLine(...)

   $canvas->create('line', ...);

Actions on canvas items are not via the common configure interface, because they are no objects: the canvas stores the information of items internally. For items, you have to use $canvas->itemconfigure.

Furthermore, there are complex canvas functions like move. Those functions work on single items or on groups of items which share the same tag.
