KeyPressed Undefined #52

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Global Keyboard Listener example at official page
2. Any combination of pressed keys

The example will output "Key Pressed: Undefined" for any key that I press. Key 
Pressed and Key Released are ok.

I use JDK 1.7.0u10 64bit on Windows 7 64 bit

And I'm using the 1.1.4 release of JNativeHook.

Can you please be more specific?  Do you mean that keyText=Undefined for key 
typed events?  For example: 
"NATIVE_KEY_TYPED,keyCode=0,keyText=Undefined,keyChar='a',keyLocation=KEY_LOCATI
ON_STANDARD,rawCode=38"?

For sure. I implemented the following straightforward method to print the 
available output: 

public void nativeKeyTyped(NativeKeyEvent e) {
  System.out.println("Key Text "+NativeKeyEvent.getKeyText(e.getKeyCode()));
  System.out.println("Mod Text "+NativeKeyEvent.getModifiersText(e.getKeyCode()));
  System.out.println("Key Char "+e.getKeyChar());
  System.out.println("Key Code "+e.getKeyCode());
  System.out.println("Key Loc "+e.getKeyLocation());
  System.out.println("Raw Code "+e.getRawCode());
  System.out.println("Modif "+e.getModifiers());
}

I printed the output for some the keys in my "qwerty" keyboard. The output file 
is in attach.
Please, let me know if you need some additional data.
Thank you

This is more of a design choice than an issue.  Please see paragraph 4 of the 
documentation for NativeKeyEvent. 
(http://jnativehook.googlecode.com/svn/tags/javadoc-1.1/org/jnativehook/keyboard
/NativeKeyEvent.html)  "For NATIVE_KEY_TYPED events, the getKeyCode method 
always returns VK_UNDEFINED."  This is the same behavior you will get using 
Oracle/Sun's KeyEvent implementation.  
(http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html)  "For 
key pressed and key released events, the getKeyCode method returns the event's 
keyCode. For key typed events, the getKeyCode method always returns 
VK_UNDEFINED. The getExtendedKeyCode method may also be used with many 
international keyboard layouts."

If you have any questions, please let me know.

Thank you for the explanation: I was not aware of that! Honestly, I missed the 
whole class description and I only read the method doc. However, I suggest to 
update the description of the methods such that this fact is reported there. 
Regards, 
Roberto

No problem.  Yah I agree, there seems to be some confusion regarding that 
method from time to time.  I will add an additional verbiage to the callback 
method.
