  1. POWhy KeyTyped event does not show under Linux when typing unicode?
    text
    copied!<p>I have a Swing Application running under Linux, that has problems to display accented characters.</p> <p>Looking into the application, I tracked the problem to the Keyboard. I added a new EventQueueManager to intercept all events received. </p> <p>I typed the "[dead acute] [a]" sequence on both systems.</p> <p>In windows I get:</p> <pre><code>D 090116 100330.015000 AWT-EventQueue-1 [HotKeyManager.java : 133 - handleAWTEvent] java.awt.event.KeyEvent[KEY_PRESSED,keyCode=129,keyText=Dead Acute,keyChar='´',keyLocation=KEY_LOCATION_STANDARD] on frame0 D 090116 100330.109000 AWT-EventQueue-1 [HotKeyManager.java : 133 - handleAWTEvent] java.awt.event.KeyEvent[KEY_PRESSED,keyCode=65,keyText=A,keyChar='a',keyLocation=KEY_LOCATION_STANDARD] on frame0 D 090116 100330.109000 AWT-EventQueue-1 [HotKeyManager.java : 133 - handleAWTEvent] java.awt.event.KeyEvent[KEY_TYPED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar='á',keyLocation=KEY_LOCATION_UNKNOWN] on frame0 D 090116 100330.125000 AWT-EventQueue-1 [HotKeyManager.java : 133 - handleAWTEvent] java.awt.event.KeyEvent[KEY_RELEASED,keyCode=129,keyText=Dead Acute,keyChar='´',keyLocation=KEY_LOCATION_STANDARD] on frame0 D 090116 100330.203000 AWT-EventQueue-1 [HotKeyManager.java : 133 - handleAWTEvent] java.awt.event.KeyEvent[KEY_RELEASED,keyCode=65,keyText=A,keyChar='a',keyLocation=KEY_LOCATION_STANDARD] on frame0 </code></pre> <p>Under Linux I get:</p> <pre><code>D 090116 151026.380000 AWT-EventQueue-0 [HotKeyManager.java : 132 - handleAWTEvent] java.awt.event.KeyEvent[KEY_RELEASED,keyCode=0,keyText=Unknown keyCode: 0x0,keyChar='?',keyLocation=KEY_LOCATION_UNKNOWN] on frame0 </code></pre> <p>So it seems that there is some difference in the way the keyboard is handled. Maybe some type of character encoding issue?</p>
