5. A new look and feel drawing panel with reversed colors

        Make your graph drawing CAD like.

    If you need to draw white shapes on a totally black background, you'll get trouble in former version of JFDraw. But now you need only to turn off or turn on the reverse switch, there is almost no other things need to do!

         Sample codes of a reversed color DrawCanvas.

//Action: create a draw panel
//Desc: A DrawPane object packaged a vertical ruler, a horizontal ruler and a drawing canvas
DrawPane panel =new DrawPane();

//Action: get the draw canvas which is inside of a DrawPane object.
//Desc: A DrawCanvas object is used to draw all of the shapes
DrawCanvas canvas =panel.getDrawCanvas();

//set current canvas into a reverse color
canvas.setReverse(true);
