Listing the Key Bindings in a JTextComponent Keymap</h3>
A text component has an additional list of key bindings that is
searched after its input maps. This additional list is called a
keymap. The input map mechanism is newer but keymaps were left in
place for backwards compatibility.
<pre>
JTextArea component = new JTextArea();
Keymap map = component.getKeymap();
while (map != null) {
KeyStroke[] keys = map.getBoundKeyStrokes();
for (int i=0; i<keys.length; i++) {
// This method is defined in <a href="../javax.swing/Key2Str.html" class="eglink"><font size="-1"><b>e858</b> Converting a KeyStroke to a String</font></a>
String keystrokeStr = <font color="#0066ff"><i> </i></font>keyStroke2String(keys[i]);
// Get the action name bound to this keystroke
Action action = (Action)map.getAction(keys[i]);
}
// The default action is invoked if a character is typed
// and no key binding exists in the component's InputMap or Keymap.
Action defAction = map.getDefaultAction();
// Process all parent keymaps as well
map = map.getResolveParent();
}
