Question

I don’t want to get called events during the render or update step, but before them. I also don’t want to only redraw when an event has occurred, but as soon as possible, so I need a loop in my program.

• poll events – call functions to associated listeners
• update – may be merged with draw
• draw

How can I accomplish this?

I don’t really understand your problem, but if you want to draw continuously, then you should make a main loop. This thing cannot be made with swing components, but only if you design an event or use a predefined event. In that event, redraw the whole canvas, using validate() when you add a new component and repaint() or paint() when you just want to update the image.

If you don’t want to render continuously then just render when “something” happens, such as when an event triggers.
