How to set the cut/copy/paste keybindings ?
Juancho
I'm using the Motif look and feel, but I'd like to keep the win32
cut/copy/paste keybindings.
Does anyone know any way to do this in JTextComponent ?
I've been trying to set them like:
c.getInputMap().put(KeyStroke.getKeyStroke('X',
java.awt.Event.CTRL_MASK), "cut");
But with no sucess.
On the other hand, I tried to copy them from the Win LnF:
LookAndFeel win = UIManager.getLookAndFeel();
...
UIManager.put("TextArea.keyBindings",
win.getDefaults().get("TextArea.keyBindings"));
Again, with no sucess.
Any solution would be really welcome.
Thanks in advance,
- Juancho

I have thought it would be the same for all three, via Ctrl+X, but
possibly it is Shift-X on Motif, I don't remember it right now. In
DefaultEditorKit cutAction is registered as "cut-to-clipboard",thus
IMO it should work if you change the InputMap then with this as the
actionMapKey in InputMap.put() and then with textComponent.cut();.
KeyStroke key = KeyStroke.getKeyStroke("ctrl X");
c.getInputMap().put(key, "cut-to-clipboard");
c.getActionMap().put("cut-to-clipboard", new AbstractAction() {
public void actionPerformed(ActionEvent ae) {
c.cut();
}
});
Or as you have had that via:
c.getInputMap()
.put(KeyStroke.getKeyStroke('X', java.awt.Event.CTRL_MASK),
"cut-to-clipboard");
for example - hope this helps

^^^^^
Who said it was called like that?
Use DefaultEditorKit.cutAction (which is "cut-to-clipboard").

Too little context to say what it wrong.

Whay I'm trying to do is:
When the application starts (so the standard windows look and feel
is selected), store it into a variable.
LookAndFeel win = UIManager.getLookAndFeel();
And them, after setting the motif look and feel, retrieve the old
key bindings.
Ex.
UIManager.put("TextArea.keyBindings", win.getDefaults().get
("TextArea.keyBindings"));
This -at least the way I'm doing it- doesn't work.
I've been browsing the help in the sun site, and I found how to set
normal key bindings, but no info about how to hook them to the usual
clipboard commands.

But why should it be called "win"?
You don't know which LookAndFeel is set then.

It only works for JTextAreas create after that line.

Just the WINdows look and feel..

The problem is that it doesn't work at all..

No, you don't know which LookAndFeel is set then, unless there is a
line
UIManager.setLookAndFeel(new WindowsLookAndFeel());
just above, in which case that line is pointless.

You should have provided a compilable example, which would have
been very easy in this case.
In 1.4, the magic defaults key is name "TextArea.focusInputMap" instead.
import javax.swing.*;
import javax.swing.plaf.metal.MetalLookAndFeel;
import com.sun.java.swing.plaf.windows.WindowsLookAndFeel;
import com.sun.java.swing.plaf.motif.MotifLookAndFeel;
import java.util.Hashtable;
public class T
{
public static void main(String[] args)
throws Exception
{
LookAndFeel from = new WindowsLookAndFeel();
from.initialize();
Hashtable defaults = from.getDefaults();
copy(defaults, "TextArea.keyBindings");
copy(defaults, "TextArea.focusInputMap");
from.uninitialize();
UIManager.setLookAndFeel(new MotifLookAndFeel());
JTextArea t = new JTextArea();
JFrame f = new JFrame();
f.getContentPane().add(new JScrollPane(t));
f.pack(); f.show();
}
private static void copy(Hashtable from, String key)
{
Object value = from.get(key);
if (value != null)
UIManager.put(key, value);
}
}
[
Funny sidenote, WindowsLookAndFeel does the following for me in 1.4:
Exception in thread "main" java.lang.NumberFormatException: multiple points
at java.lang.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1073)
at java.lang.Float.valueOf(Float.java:186)
at com.sun.java.swing.plaf.windows.WindowsLookAndFeel.initialize(WindowsLookAndFeel.java:108)
at T.main(T.java:16)
because it actually tries to parse the system property "os.version" as
a float.
]
So better use MetalLookAndFeel as a source for the keybindings if you
want your code to work on all OSes.

Christian, thank you for help !
I've completly solved the problem now. I'm also starting to
understand how key binding really works.
