When repaint() is called, does it simply redraw the current layer, or does
it try to redraw all layers?
In a BufferedMapBean application with multiple layers, does it make sense to
allow each layer to call repaint() as they change, or should one, single
repaint() be called after all layers are updated?
In reviewing EditableOMGraphic, it seems that when the object is moved:
- the entire map is marked dirty - map.setBufferDirty(true)
- all of the graphics are repainted - map.paintChildren(map.getGraphics())
Now, if a user is dragging an object around, they obviously cannot be
dragging around multiple objects, so maybe regerating the whole map during a
drag makes sense. However, what is the best way to manage repaint() in an
application with multiple graphics on multiple layers that are constantly
updated?
Thanks-
Chris
