Hallo! Zusammen,
habe schon einiges hier gelesen über das Flackern nur hat es mich eher verwirrt als mir geholfen.
Die angebotenen Lösungen beziehen sich meist auf Spiele einerseits und andererseite taucht immer wieder der Begriff doubleBuffering auf ( was Swing aber von hausaus machen sollte).
Im grunde habe ich nichts anderes gemacht als einmal ganz einfach nach rezept OpenOffice eingebunden.
Funktioniert auch wunderbar nur wenn man die Fenstergröße mit der Maus ändert, dann flackerts.
Kann mir bitte jemand einen link oder code posten?
Danke!
