I have a JTextPane
. I want my own behavior for Ctrl+Arrow
presses.
jTextEntryPane.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_UP, Toolkit.getDefaultToolkit ().getMenuShortcutKeyMaskEx()), Controls.UP_ACTION);
jTextEntryPane.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_DOWN, Toolkit.getDefaultToolkit ().getMenuShortcutKeyMaskEx()), Controls.DOWN_ACTION);
jTextEntryPane.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_LEFT, Toolkit.getDefaultToolkit ().getMenuShortcutKeyMaskEx()), Controls.LEFT_ACTION);
jTextEntryPane.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_RIGHT, Toolkit.getDefaultToolkit ().getMenuShortcutKeyMaskEx()), Controls.RIGHT_ACTION);
jTextEntryPane.getActionMap().put(Controls.UP_ACTION, new MoveAction(Controls.UP_ACTION, this));
jTextEntryPane.getActionMap().put(Controls.DOWN_ACTION, new MoveAction(Controls.DOWN_ACTION, this));
jTextEntryPane.getActionMap().put(Controls.LEFT_ACTION, new MoveAction(Controls.LEFT_ACTION, this));
jTextEntryPane.getActionMap().put(Controls.RIGHT_ACTION, new MoveAction(Controls.RIGHT_ACTION, this));
Ctrl+Up
and Ctrl+Down
work.
Ctrl+Left
and Ctrl+Right
do not, but instead are being used by the text field (to go to the beginning or end of the input field). I want to replace their behavior, but I do not want to change the regular arrow (left and right) behavior. How do I do this?
Ctrl+Up and Ctrl+Down are currently not defined as key bindings for the text field so you are just adding new bindings, which is why they work.
However, Ctrl+Left and Ctrl+Right are already defined as bindings for a JTextField. They are defined for the WHEN_FOCUSED
InputMap which has priority over the WHEN_IN_FOCUSED_WINDOW
InputMap.
jTextEntryPane.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW)....
You are using the wrong InputMap for all your bindings.
You should be using:
jTextEntryPane.getInputMap()....
which will use the WHEN_FOCUSED
InputMap.
This will allow you to replace the default Action.
See Key Bindings for a simple program that displays all the default bindings for each component.
Edit:
Tabbing is not handled by the Key Bindings. It is handled by the focus subsystem, so the event is intercepted before it gets to the text field. I believe the following should work:
textField.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, null);
textField.setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, null);
