Why does Swing in my Java Applet flicker on fast mouse over?

问题

I made a Java Applet with some Standard GUI Components on it. I used the MigLayout Manager.

If I move the mouse slowly over the various GUI Components everything appears to be fine, but if I move the mouse fast, it flickers.

What could make that nasty ugly redraw? (Core 2 Duo 6300, 2GB Ram, Windows XP)

回答1:

One thought would be to check your code (and/or the MigLayout code) for unnecessary repaint() operations.

Custom UIs and layouts can cause weird problems sometimes...

回答2:

you could use double buffering in java applet to improve screen refreshing speed. ask more if details needed..

回答3:

I found the bugger: I used a custom ClosableTabbedPaint Class.
