Newt KeyEvent "typed" only produced on release and auto-repeat

While developing a small OpenGL/OpenCL game using JOGL and JOCL, we've run into a problem with newt KeyEvents.

As we target Windows (and other platforms), and want to support chat, we need to be able
to get correct key characters for different keyboard events.

(These tests are on oracle's java7 64 bit jvm on windows 7 using jogl 2.0-rc11)

Jogl NEWT KeyEvent typed events deliver the correct characters, HOWEVER:
The first typed event arrives with a significant delay, since the event is only
produced when the key is released (or when the first autorepeat kicks in).

This is problematic as it makes text input seem very sluggish.

Pressed-events are delivered instantly, however as documented, these do not give full character information.

Is there any known way to solve or work around this?
Is there any jogl beta where typed events get delivered faster on windows or where Pressed events contain character info?

Don't look for a "beta", we will try to find a clean solution. Wouldn't you have a similar problem with AWT?

You could use the key-code, which ofc would be a PIA for you - hmm.

But I see your point .. and I will look into this again and reply here
in a while ..

No AWT produces the typed event as soon as you hit the key - not on release.

I just tested it using:

package test;

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JFrame;

public class AwtTest {

public static void main(String[] args) {
final JFrame x = new JFrame();
x.setSize(400, 300);
x.setVisible(true);

x.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
x.dispose();
}
});

x.addKeyListener(new KeyAdapter() {
@Override
public void keyTyped(KeyEvent e) {
System.out.print(e.getKeyChar());
}
});
}

}

Ok, 2 threads? :). Should I write here or in the other thread?
In the meantime I think I'll just lazy in a JNA keyboard hook.

I read that in the documentation:

Key releases are not usually necessary to generate a key typed event, but there are some cases where the key typed event is not generated until a key is released

It seems to be possible to do the same.

There is only one thread now :) Please tell us which native functions you will call, it might be helpful.

Good NEWS:
https://jogamp.org/bugzilla/show_bug.cgi?id=678

I will implement this change now .. and notify you.

I see it is marked as "Fixed" here https://jogamp.org/bugzilla/show_bug.cgi?id=678 .

Which version is it implemented in? Where can I get it :). I'm currently in 2.0 rc-11 but if you point me to the beta with the fix I'll grab that ASAP.

Can get it as a beta release jar? I'd rather not have to build the native jogl on windows and package it in a jar..

BTW thanks a lot for the quick fix!

Sven, please can you make another autobuild? The latest one doesn't contain this fix.

Yup .. in progress.
I currently fix a OSX/Java7 node to our Jenkins, then I kick off the 'machine'
- incl. JOAL merge.

Any news yet on that build? ;)

Sorry for being impatient hehe. Thanks for your work!

Re: Newt KeyEvent "typed" only produced on key-up and auto-repeat

I saw a new release at http://jogamp.org/deployment/archive/master/gluegen_629-joal_396-jogl_903-jocl_741-signed/

But this did NOT fix the issue. Waiting for word from you when a new version will be out :).

The build I tried above gives the following results:

"typed" is still sent on key release,
however "pressed" now contains the same information as typed, so that is good.

BUT:
Both have many incorrect mappings. They procude the same values, but don't seem to match my keyboard layout properly.

For example Alt Gr + 'the button left of z' (Swedish keyboard) should produce | , the button itself should be < and with shift it should be >. However the events all give me < .

Reopen the former bug report or write a new one. Maybe consider writing another unit test to exhibit the problematic behaviour.

Bug 678 https://jogamp.org/bugzilla/show_bug.cgi?id=678
is fixed - the remaining issue reported,
key-code depends key layout, matches existing bug 668

types shall be sent after key release (NEWT KeyEvent spec)
and this is validated in fix of bug 678

Key-code or key-char ?

Probably related to bug 668 ?
https://jogamp.org/bugzilla/show_bug.cgi?id=668

How can we have a reliable unit test ?

Re: Newt KeyEvent "typed" only produced on key-up and auto-repeat

Ok let me make it clearer:

Pressed and Typed now produce the same key chars: GOOD!, thx!

However the keyChars for several combinations are incorrect.

For example on a swedish keyboard (with the layout in the image posted above),
ALT gr + "<" (< being the button left of z) should proce a "|"

Most combinations using Alt GR are incorrect (but not all)

It seems like a layout issue.

Thx .. I will tackle this again soon w/ bug 668,
trying to use such a keyboard layout.

Maybe you can add your findings w/ keyboard layout picture to bug 668.

Thank you, Sven
