Field Details

LONG_PRESS_INTERVAL

public static Style<Integer> LONG_PRESS_INTERVAL

An interval (in milliseconds) after which pressing and holding on a button will be interpreted as a "long press" and fire a clicked event. The button is then disarmed, so that when the button is released after a long press, a normal click event is not reported. Defaults to 1000ms.

Method Details

longPressed

public react.SignalView<Button> longPressed()

A signal that is emitted when this button is long pressed. See LONG_PRESS_INTERVAL.

longPress

public void longPress()

Programmatically triggers a long press of this button. This triggers the action sound, but does not cause any change in the button's visualization. Note: this does not check the button's enabled state, so the caller must handle that if appropriate.

onLongPress

public LongPressButton onLongPress(react.SignalView.Listener<? super Button> onLongPress)

A convenience method for registering a long press handler. Assumes you don't need the result of SignalView.connect(react.SignalView.Listener<? super T>), because it throws it away.
