public Class ButtonBehavior<C extends ButtonBase>

Class Inheritance

extends BehaviorBase<C extends ButtonBase>

java.lang.Object
com.sun.javafx.scene.control.behavior.BehaviorBase
com.sun.javafx.scene.control.behavior.ButtonBehavior

Known Direct Subclasses

com.sun.javafx.scene.control.behavior.MenuButtonBehaviorBase, com.sun.javafx.scene.control.behavior.ToggleButtonBehavior

Imports

com.sun.javafx.PlatformUtil, com.sun.javafx.scene.control.inputmap.KeyBinding, .InputMap, javafx.beans.InvalidationListener, .Observable, javafx.scene.control.ButtonBase, javafx.scene.input.KeyEvent, .MouseButton, .MouseEvent

All of the "button" types (CheckBox, RadioButton, ToggleButton, and Button) and also maybe some other types like hyperlinks operate on the "armed" selection strategy, just like JButton. This behavior class encapsulates that logic in a way that can be reused and extended by each of the individual class behaviors.

focusListener	back to summary
private InvalidationListener focusListener

keyDown	back to summary
private boolean keyDown Indicates that a keyboard key has been pressed which represents the event (this could be space bar for example). As long as keyDown is true, we are also armed, and will ignore mouse events related to arming. Note this is made package private solely for the sake of testing.

Annotations

@Override

keyPressed	back to summary
protected void keyPressed(KeyEvent e) This function is invoked when an appropriate keystroke occurs which causes this button to be armed if it is not already armed by a mouse press.

keyReleased	back to summary
protected void keyReleased(KeyEvent e) Invoked when a valid keystroke release occurs which causes the button to fire if it was armed by a keyPress.

mouseEntered	back to summary
protected void mouseEntered(MouseEvent e) Invoked when the mouse enters the Button. If the Button had been armed by a mouse press and the mouse is still pressed, then this will cause the button to be rearmed.

mouseExited	back to summary
protected void mouseExited(MouseEvent e) Invoked when the mouse exits the Button. If the Button is armed due to a mouse press, then this function will disarm the button upon the mouse exiting it.

mousePressed	back to summary
protected void mousePressed(MouseEvent e) Invoked when a mouse press has occurred over the button. In addition to potentially arming the Button, this will transfer focus to the button

mouseReleased	back to summary
protected void mouseReleased(MouseEvent e) Invoked when a mouse release has occurred. We determine whether this was done in a manner that would fire the button's action. This happens only if the button was armed by a corresponding mouse press.
