KeyEvent Handling

Question

Hello everyone.
I'm using Netbeans 5.0 to build a form project. I have a class that extends from JFrame and I wanted to make it a KeyListener. So I set on the design window the desired events I wanted my frame to handle, which were keyPressed, keyReleased and keyTyped. Netbeans has generated the following code:
addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyPressed(java.awt.event.KeyEvent evt) {
                formKeyPressed(evt);
            public void keyReleased(java.awt.event.KeyEvent evt) {
                formKeyReleased(evt);
            public void keyTyped(java.awt.event.KeyEvent evt) {
                formKeyTyped(evt);
        });and also generated the methods formKey<action> stated above. I wrote the methods and they work ok. But when I ran the project the key listening didn't work properly. Using Netbeans debugger, I found out that the following happens: in the code above, when the first method is called (formKeyPressed), the object evt is correctly set, with a valid key code. The program goes on because the key that I pressed is suposed to be treated in formKeyTyped. When formKeyTyped is invoked, however, object evt has its code set to 0, although its char is unchanged. Does anyone knows why it happens?

Answer 1

and the key handling code is built as follows
switch (evt.getKeyCode()){
              case KeyEvent.VK_MINUS:
               //code
               break;
              case KeyEvent.VK_UNDERSCORE:
               //code
               break;
}in all three methods
