First Draw2D

You need draw2d.jar of GEF and swt.jar to run below program.


At first it's need to create FigureCanvas.
FigureCanvas connect Components and Figures.
Besides that there are LightweightSystem

FigureCanvas canvas = new FigureCanvas(shell);

Next ,it need to create Panel of Draw2D which is one of Figures. And set FlowLayout as Layout. On Draw2D figure is set as tree ,So it's need root Figure. And Method setContens() set root Figure .

Panel panel=new Panel(); panel.setLayoutManager(new FlowLayout(false)); canvas.setContents(panel);
Finally,it add labels of Draw2D. On Draw2D,there are no need to add a parent Figure argument,because it add a children figure to a parent Figure directly.

for(int i=0;i<3;i++){
Label label=new Label("draw2d "+i);
panel.add(label);
