The canvas gadget is the gadget equivilent of a blank piece of paper, using the canvas drawing commands (including drawLine, drawPoint, drawRect, drawEllipse, drawText and setDrawingColor) you can use it to create your custom gadgets or use it to display status info such as graphs.

In Rainbow you just place the canvas gadget and it will appear as a black rectangle, to make it useful you have to add drawing code in the DarkBASIC editor.

For an example, have a look at the Canvas example in the 'Simple Gadget' folder.
