Usage

From source file:Main.java

/**
 * A helper for creating and updating key bindings for components with
 * mnemonics. The {@code pressed} action will be invoked when the mnemonic
 * is activated and the {@code released} action will be invoked when the
 * mnemonic is deactivated./*w w  w  .  j a va 2 s.c o  m*/
 * <p>
 * TODO establish an interface for the mnemonic properties, such as {@code
 * MnemonicEnabled} and change signature to {@code public static <T extends
 * JComponent & MnemonicEnabled> void updateMnemonicBinding(T c, String
 * pressed, String released)}
 * 
 * @param c
 *            the component bindings to update
 * @param pressed
 *            the name of the action in the action map to invoke when the
 *            mnemonic is pressed
 * @param released
 *            the name of the action in the action map to invoke when the
 *            mnemonic is released (if the action is a toggle style, then
 *            this parameter should be {@code null})
 * @throws NullPointerException
 *             if the component is {@code null}
