Hi every body,
I have got one question, still about my very large number of draw2D
figures. is it possible, using Draw2D, to reuse an already drawn figure in
an other location into the same parent figure. In other words, is it
possible with only one figure instance into the JVM to draw this figure 2
or more times into my panel??
for example:
myPanel.add(myFigure, new Rectangle(10,10,10,10);
myPanel.add(myFigure, new Rectangle(50,50,10,10);
Thanks
Manu

Yes, you can simply ask a figure to paint on a Graphics. You may have to
translate the graphics to get the desired placement, and most figures
require a parent, which can simply be set to some figure in the diagram.
If you need to alter the figure before it paints, slightly more is involved.
You may have to validate() it.

Thanks every body,
I was just thinking about using the flying pattern to reduce the number of
draw2d figures in my chart. But i think it is impossible to do it using
the classic Draw2D figures wich implements the Figure class. Isn't it ??
Shoul i have to implement my own figures by implementing the IFigure like
Steven said interface or is there an other easier way to do this ??
Thanks.
PS : If someone has already used the flyweight pattern with Draw2D please
can you send me a piece of code wich explain how in more details.
