Constructors

Modifier	Constructor	Description
	JMenuItem()
protected	JMenuItem(com.vaadin.flow.component.Component peer)	Protected (Component peer) ctor — D_peer_ctor_injection seam.

Method Summary

Modifier and Type	Method	Description
void	addMenuDragMouseListener(MenuDragMouseListener l)
void	addMenuKeyListener(MenuKeyListener l)
KeyStroke	getAccelerator()
AccessibleContext	getAccessibleContext()
Component	getComponent()	Returns a real object only because MenuElement is ported: against the JDK interface this had to be typed java.awt.Component, which a JMenuItem is not, so it could only return null (R_no_vaadin_in_api limb 1).
MenuDragMouseListener[]	getMenuDragMouseListeners()
MenuKeyListener[]	getMenuKeyListeners()
MenuElement[]	getSubElements()
String	getUIClassID()
void	menuSelectionChanged(boolean isIncluded)
void	processKeyEvent(KeyEvent e, MenuElement[] path, MenuSelectionManager manager)
void	processMouseEvent(MouseEvent event, MenuElement[] path, MenuSelectionManager manager)
void	removeMenuDragMouseListener(MenuDragMouseListener l)
void	removeMenuKeyListener(MenuKeyListener l)
void	setAccelerator(KeyStroke keyStroke)	JDK fires "accelerator" PCE; the rebuild then walks to find this item's MenuNode and re-installs the UI-scoped shortcut on the new keystroke (or skips install when the keystroke is unmappable).
void	setActionCommand(String command)
void	setEnabled(boolean enabled)	Enables the component and its model, which is what gates AbstractButton.doClick() and a click.

JMenuItem

public JMenuItem(Action a)

JMenuItem

protected JMenuItem(com.vaadin.flow.component.Component peer)

Protected (Component peer) ctor — D_peer_ctor_injection seam. JMenuItem is non-leaf (JMenu / JCheckBoxMenuItem / JRadioButtonMenuItem subclass it), so the seam carries through. User-code subclasses passing a custom peer get a JMenuItem whose peer is unreachable from the rendered DOM (the actual Vaadin MenuItem is built per rebuild) — acceptable per D_menu_tree (the migrator's intent for JMenuItem subclassing is server-side state + listeners, not custom Vaadin chrome).

JMenuItem

protected <P extends com.vaadin.flow.component.Component>
JMenuItem(Class<P> peerType,
 Supplier<? extends P> peerFactory)

The lazy form: see Component(Class, java.util.function.Supplier).

Method Details

setText

public void setText(String text)

Overrides:

setText in class AbstractButton

setIcon

public void setIcon(Icon icon)

Overrides:

setIcon in class AbstractButton

setActionCommand

public void setActionCommand(String command)

Overrides:

setActionCommand in class AbstractButton

setEnabled

public void setEnabled(boolean enabled)

Description copied from class: AbstractButton

Enables the component and its model, which is what gates AbstractButton.doClick() and a click.

Overrides:

setEnabled in class AbstractButton

getAccelerator

public KeyStroke getAccelerator()

setAccelerator

public void setAccelerator(KeyStroke keyStroke)

JDK fires "accelerator" PCE; the rebuild then walks to find this item's MenuNode and re-installs the UI-scoped shortcut on the new keystroke (or skips install when the keystroke is unmappable).

getSubElements

public MenuElement[] getSubElements()

Specified by:

getSubElements in interface MenuElement

getComponent

public Component getComponent()

Returns a real object only because MenuElement is ported: against the JDK interface this had to be typed java.awt.Component, which a JMenuItem is not, so it could only return null (R_no_vaadin_in_api limb 1).

Specified by:

getComponent in interface MenuElement

Returns:

this — the JDK's own answer, a menu item being its own Component representation.

menuSelectionChanged

public void menuSelectionChanged(boolean isIncluded)

Specified by:

menuSelectionChanged in interface MenuElement

processKeyEvent

public void processKeyEvent(KeyEvent e,
 MenuElement[] path,
 MenuSelectionManager manager)

Specified by:

processKeyEvent in interface MenuElement

processMouseEvent

public void processMouseEvent(MouseEvent event,
 MenuElement[] path,
 MenuSelectionManager manager)

Specified by:

processMouseEvent in interface MenuElement

getUIClassID

public String getUIClassID()

Overrides:

getUIClassID in class JComponent

updateUI

public void updateUI()

Overrides:

updateUI in class AbstractButton

getAccessibleContext

public AccessibleContext getAccessibleContext()

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Component

addMenuKeyListener

public void addMenuKeyListener(MenuKeyListener l)

removeMenuKeyListener

public void removeMenuKeyListener(MenuKeyListener l)

getMenuKeyListeners

public MenuKeyListener[] getMenuKeyListeners()

addMenuDragMouseListener

public void addMenuDragMouseListener(MenuDragMouseListener l)

removeMenuDragMouseListener

public void removeMenuDragMouseListener(MenuDragMouseListener l)

getMenuDragMouseListeners

public MenuDragMouseListener[] getMenuDragMouseListeners()
