Description

The list of methods to do Swing Key Action are organized into topic(s).

Method

voidescapeKeyAction(JComponent component, javax.swing.AbstractAction abstractAction)
escape Key Action 
component.getRootPane().getActionMap().put(ESC_ACTION_KEY, abstractAction);
component.getRootPane().getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT)
        .put(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), ESC_ACTION_KEY);
StringformatKeyStroke(final KeyStroke keyStroke)
pretty print a keystroke. 
final String keyModifiersText = KeyEvent.getKeyModifiersText(keyStroke.getModifiers());
final String keyText = KeyEvent.getKeyText(keyStroke.getKeyCode());
return keyModifiersText.length() == 0 ? keyText : keyModifiersText + "+" + keyText;
StringgetActionID(final Action a)
Tries to find an ID for the passed action from its Action#getValue(String) properties . 
Object actionID = a.getValue(Action.ACTION_COMMAND_KEY);
if (actionID == null)
    actionID = a.getValue(Action.NAME);
return actionID == null ? null : actionID.toString();
StringgetActionInstanceName(Action delegate)
get Action Instance Name 
Object commandKey = delegate.getValue(Action.ACTION_COMMAND_KEY);
String id;
if (commandKey != null && !commandKey.toString().isEmpty()) {
    id = commandKey.toString();
} else {
    id = delegate.getClass().getName();
id = id.replace('/', '-').replace('.', '-').replace('$', '-');
...
KeyStrokegetEscapeKeystroke()
get Escape Keystroke 
return KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0);
KeyStrokegetKeyStroke(int i0, int i1)
get Key Stroke 
if ((i1 & KeyEvent.META_MASK) != 0) {
    if (!onMac) {
        i1 = i1 - KeyEvent.META_MASK + KeyEvent.CTRL_MASK;
KeyStroke ks = KeyStroke.getKeyStroke(i0, i1);
if (debug) {
    Exception ex = new Exception();
...
KeyStrokegetKeystroke(int keyevent)
Returns a cross-platform keystroke that enables the platform behave natively. 
return KeyStroke.getKeyStroke(keyevent, Toolkit.getDefaultToolkit().getMenuShortcutKeyMask());
KeyStrokegetKeyStrokeCopy()
get Key Stroke Copy 
return KeyStroke.getKeyStroke(KeyEvent.VK_C, ActionEvent.CTRL_MASK, false);
StringgetKeyStrokeRepresentation(KeyStroke ks)
Returns a String representation for the given KeyStroke for display, in the following format:
modifier+modifier+...+key

For example, KeyStroke.getKeyStroke(KeyEvent.VK_C, InputEvent.CTRL_MASK|InputEvent.ALT_MASK) will return Ctrl+Alt+C.

return ks.toString().replaceFirst("(released )|(pressed )|(typed )", "");
StringgetKeyStrokeText(KeyStroke ks)
get Key Stroke Text 
StringBuilder sb = new StringBuilder();
String modifierText = KeyEvent.getKeyModifiersText(ks.getModifiers());
sb.append(modifierText);
String keyText = KeyEvent.getKeyText(ks.getKeyCode());
if (!keyText.isEmpty() && !modifierText.contains(keyText)) {
    if (sb.length() > 0) {
        sb.append('+');
    sb.append(keyText);
return sb.toString();
