Creating custom components in Java AWT -

i trying create custom component using java awt or swing rectangle number of components inside of it, including other rectangles. this:

╔══════╗ ║  ┌┐  ║ ║  ├┘  ║ ║      ║ ╚══════╝ 

and needs component can preferably draw 1 instruction. myframe.add(new mycomponent()).

what best way this? there way can using rectangle, or should go jpanel or swing?

i recomend extending jpanel , overriding it's paintcomponent() method. see another answer of mine on that.

basically, when rectangle 'drawn' on panel, want save member of jpanel. then, in paintcomponent method, draw of rectangles have saved in jpanel.

this how implement 'draw' method:

list<rectangle> recs; list<stroke> strokes; list<color> colors; public void drawrectangle(rectangle newr, stroke stroke, color c){     recs.add(newr);     strokes.add(stroke);     colors.add(c); } 

and, paint component similar to:

protected void paintcomponent(graphics g){     super.paintcomponent(g);     (int = 0; < recs.size(); ++) {         g.setcolor(colors.get(i));         g.setstroke(strokes.get(i));         g.drawrectangle(recs);     } }
