,MenuButton
,ToggleButton
Base class for button-like UI Controls, including Hyperlinks, Buttons,
ToggleButtons, CheckBoxes, and RadioButtons. The primary contribution of
ButtonBase is providing a consistent API for handling the concept of button
"arming". In UIs, a button will typically only "fire" if some user gesture
occurs while the button is "armed". For example, a Button may be armed if
the mouse is pressed and the Button is enabled and the mouse is over the
button. In such a situation, if the mouse is then released, then the Button
is "fired", meaning its action takes place.

armed
Indicates that the button has been "armed" such that a mouse release will cause the button's action to be invoked. This is subtly different from pressed. Pressed indicates that the mouse has been pressed on a Node and has not yet been released.arm

-
onAction
The button's action, which is invoked whenever the button is fired. This may be due to the user clicking on the button with the mouse, or by a touch event, or by a key press, or if the developer programmatically invokes thefire()
method.

arm
public void arm()Arms the button. An armed button will fire an action (whether that be the action of aButton
or toggling selection on aCheckBox
or some other behavior) on the next expected UI gesture. Note: This function is intended to be used by experts, primarily by those implementing new Skins or Behaviors. It is not common for developers or designers to access this function directly. -
disarm
public void disarm()Disarms the button. Seearm()
. Note: This function is intended to be used by experts, primarily by those implementing new Skins or Behaviors. It is not common for developers or designers to access this function directly. -
fire
public abstract void fire()Invoked when a user gesture indicates that an event for thisButtonBase
should occur.If invoked, this method will be executed regardless of the status of
arm()
