A key with CRTL pressed on a Control (Table), for example 'A'+CTRL.
KeyReleased gets a KeyEvent.
Checking e.stateMask & SWT.CONTROL shows that the CTRL was pressed,
but in e.character could not get the right character.

I report on Bugzilla, but it seams that they did not understand the problem
Here is an example that shows the problem.
It happen for other controls such as Text, not only for Table
package com.ibm.hrl.lds.local.ui;
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.events.*;
public class TableKeyBug {
Shell shell;
public TableKeyBug () {
shell = new Shell (new Display (), SWT.CLOSE | SWT.TITLE);
shell.setText ("Table Key Bug ");
shell.setLayout (new FillLayout ());
Table table = new Table (shell, SWT.V_SCROLL | SWT.H_SCROLL |
SWT.BORDER | SWT.MULTI | SWT.FULL_SELECTION | SWT.WRAP);
table.setSize (100,100);
table.addKeyListener (new KeyAdapter () {
public void keyReleased (KeyEvent e) {
if ((e.stateMask & SWT.CONTROL) == SWT.CONTROL) {
System.out.println ("keyReleased CONTROL");
}
// in case of CTRL+character, don't get it in e.character !!!!!
System.out.println ("keyReleased Character = "+e.character);
}
});
}
public Shell getShell () {
return shell;
}
public static void main (String [] args) {
TableKeyBug table = new TableKeyBug ();
Shell shell = table.getShell ();
Display display = shell.getDisplay ();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ())
display.sleep ();
}
display.dispose ();
}
}
