Hello everyone,     I'm starting to learn graphics with the Java 1.3 Beta, Swing, and Java2D.  Could someone please tell me if it still makes sense to derive classes from java.awt.Canvas to make animated surfaces that I can add to a layout manager?     Also, lets say I have some animation going that is being refreshed with the graphics context of the surrounding component (the component is having its paint method called repeatedly).  First, does it make sense to have the paint method called for this?  (I'm using a Timer by way of actionPerformed for this.)     Second, what if its set up like this and the user pulls down menu over the animation.  Wouldn't the animation paint over the menu (since the component below the menu is being redrawn, not the whole program be redrawn)?  If so, what's the best way to handle this?  Repaint everything, everytime?!   Thanks in advance!!
