Method Detail

default Registration addClickListener(ComponentEventListener<ClickEvent<T>> listener)

Adds a click listener to this component.

Parameters:

listener - the listener to add, not null

a handle that can be used for removing the listener

addClickShortcut

default ShortcutRegistration addClickShortcut(Key key,
                                              KeyModifier... keyModifiers)

Adds a shortcut which 'clicks' the Component which implements ClickNotifier interface. The shortcut's event listener is in global scope and the shortcut's lifecycle is tied to this component.

Use the returned ShortcutRegistration to fluently configure the shortcut.

By default, the returned ShortcutRegistration allows browser's default behavior, unlike other ShortcutRegistrations. This is used to make sure that value synchronization of input fields is not blocked for the shortcut key (e.g. Enter key). To change this behavior, call ShortcutRegistration.setBrowserDefaultAllowed(boolean).

Parameters:

key - primary Key used to trigger the shortcut. Cannot be null.

keyModifiers - KeyModifiers that need to be pressed along with the key for the shortcut to trigger

Returns:

ShortcutRegistration for configuring the shortcut and removing
