i begin with swing and to get more experience, i begined a small project.
i would like to create a basic entity-relation program who will generate sql script...

on a canvas i draw some shape (entity, link)

when i click on it a panel open.... to change its property... when it's close i would like to refresh canvas...

AWT uses "paint", but Swing uses "paintComponent": http://java.sun.com/docs/books/tutorial/uiswing/painting/closer.html

the code of my canvas (where i draw the shape)



i have no problem to draw entitydrawable on the jcanvas... i can move it, draw...
the only problem is when i change property of the entity (name, code...) in the EntityPanel, the change done is not applied....

so i need to change paint by paintcomponent in :JCanvas,

in EntityDrawable, i use paint...
