I just solved my "MetalLookandFeel-Problem": in the rt.jar of jdk1.2 there is still com.sun.java.swing.... Donīt know why.. You have just to add an "import com.sun.java.swing.*" to your java files. But in my case I then get: willi:/home/projects/swing # java SwingSet Error loading L&F: java.lang.IllegalArgumentException: Raster ShortInterleavedRaster: width = 64 height = 64 #numDataElements 1 is incompatible with ColorModel DirectColorModel: rmask=7c00 gmask=3e0 bmask=1f amask=0 Exception in thread "main" java.lang.NullPointerException at java.util.Hashtable.get(Compiled Code) at javax.swing.UIDefaults.get(Compiled Code) at javax.swing.MultiUIDefaults.get(Compiled Code) at javax.swing.UIDefaults.getUIClass(Compiled Code) at javax.swing.UIDefaults.getUI(Compiled Code) at javax.swing.UIManager.getUI(Compiled Code) at javax.swing.JPanel.updateUI(Compiled Code) at javax.swing.JPanel.<init>(Compiled Code) at javax.swing.JPanel.<init>(Compiled Code) at javax.swing.JRootPane.createGlassPane(Compiled Code) at javax.swing.JRootPane.<init>(Compiled Code) at javax.swing.JFrame.createRootPane(Compiled Code) at javax.swing.JFrame.frameInit(Compiled Code) at javax.swing.JFrame.<init>(Compiled Code) at SwingSet.main(Compiled Code) Someone told me that there is a bug with 24bit color depth. But I have only 16. And with 8 it didnīt work also. Someone who has a hint for me: Many thanks! willi ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
