Comment #17 on issue 163 by [email protected]: PSwing doesn't draw
dynamic JComponent properly
http://code.google.com/p/piccolo2d/issues/detail?id=163
Rats. This is still broken. I've been developing and testing on a very fast
MacBook
Pro. One of my colleagues ran TestPSwingDynamicComponent on a slower
Windows
machine, and when that app starts up, none of the Swing stuff outside the
PSwingCanvas is drawn. See attached screenshot, no-draw.png. When he
mouses over
areas of the frame outside the canvas, JComponents are drawn.
Looking into PSwingCanvas, I see that the Swing repaint manager is replaced
by
PSwingRepaintManager. The javadoc for
PSwingRepaintManager.addInvalidComponent
indicates that it's called by component.revalidate, and it in turn calls
PSwing.updateBounds. So what I've done by calling component.revalidate in
updateBounds is to introduce an infinite loop: component.revalidate ->
PSwingRepaintManager.addInvalidComponent -> PSwing.updateBounds ->
component.revalidate -> ... Putting a System.out.prinln at the first line
of
PSwing.updateBounds confirms this.
On my speedy Mac, everything still manages to get redraw. But on a slow
machine, the
event dispatch queue is hammered, and some things don't draw.
Back to the drawing board.
