Field Detail

keys

public KeyStroke[] keys

Successive keystroke. They must be pressed in the order they are stored in the array in order to invoke the associated action.

Constructor Detail

MultiKeyBinding

public MultiKeyBinding()

Constructor for serialization

MultiKeyBinding

public MultiKeyBinding(KeyStroke[] keys,
                       String actionName)

Constructor for assigning keystroke sequence to action

Parameters:

keys - successive keystroke that must be pressed in order to invoke action

actionName - action that will be invoked. Action is resolved from name by calling kit.getActions() after the kit is constructed

MultiKeyBinding

public MultiKeyBinding(KeyStroke key,
                       String actionName)

Compatibility constructor

MultiKeyBinding

public MultiKeyBinding(JTextComponent.KeyBinding kb)

Constructor for existing KeyBinding

Method Detail

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

updateKeyBindings

public static void updateKeyBindings(JTextComponent.KeyBinding[] target,
                                     JTextComponent.KeyBinding[] changes)

Add or replace key bindings array by changes given in the second bindings array

Parameters:

target - target list of bindings

changes - list of changes to apply: binding containing the non-null keystroke(s) and non-null action will add the binding or replace the old binding with the same keystroke(s) in the target array, binding of the non-null keystroke(s) and null action removes the binding for that keystroke from the target array (if it existed) binding containing null keystroke and non-null action adds or replaces default action
