Constructor Detail

ContextMenu

public ContextMenu()

ContextMenu

public ContextMenu(MnemonicSolver solver)

Creates an instance of ContextMenu that will automatically resolve mnemonic conflicts.

Parameters:

solver - an instance of the MnemonicSolver class. This instance will be used to resolve mnemonic conflicts between context menu items.

Method Detail

add

public void add(java.awt.Component child)

Description copied from class: MenuManager

Appends a component into the MenuManager's GUI.

Overrides:

add in class MenuManager

Parameters:

child - the child to add.

add

public void add(java.awt.Component child,
                float sectionId)

Add the specified child to the end of this context menu.

Overrides:

add in class MenuManager

Parameters:

child - menu item to add.

sectionId - floating point number used to group commands by section. Each section is automatically surrounded with JSeparators.

add

public void add(java.awt.Component child,
                float sectionId,
                boolean fixed)

Add the specified child to the end of this context menu.

Parameters:

child - menu item to add.

sectionId - floating point number used to group commands by section. Each section is automatically surrounded with JSeparators.

fixed - indicates that the mnemonics used by the specified child should be respected by any active MnemonicSolver.

addContextMenuListener

public void addContextMenuListener(ContextMenuListener l)

Adds a context menu listener. Context menu listeners listen for notification of when the menu is about to become visible or invisible.

Parameters:

l - the context menu listener.

addContextMenuListener

public void addContextMenuListener(ContextMenuListener l,
                                   java.lang.Class cls)

Adds a ContextMenuListener that is called when the type of the data represented by the current Context is assignable to a variable whose type is of the specified Class.

Parameters:

l - the ContextMenuListener to add.

cls - if non-null, the ContextMenuListener will only be notified if the current Context's data object type is assignable to a variable whose type is of the specified Class.

removeContextMenuListener

public void removeContextMenuListener(ContextMenuListener l)

Removes a context menu listener. Context menu listeners listen for notification of when the menu is about to become visible or invisible.

Parameters:

l - the context menu listener.

getContextMenuListeners

public java.util.List<Pair<java.lang.Class,ContextMenuListener>> getContextMenuListeners()

Returns a list of ContextMenuListener registered with this ContextMenu.

Returns:

an immutable list of ContextMenuListeners, each ContextMenuListener will only be notified if the current Context's data object type is assignable to a variable whose type is of the specified Class.

getGUI

public java.awt.Container getGUI(boolean create)

Creates the actual popup menu. Callers should store the returned value for use when calling the show method.

unwrapDecoratedElement

public static Element unwrapDecoratedElement(Element elem)

Returns the undecorated Element, when the ElementAttributes.DECORATES_DATA_ELEMENT attribute is set.

addMenuFilter

public final void addMenuFilter(MenuFilter menuFilter)

This implementation adds a menu filter only to the context menu. If you want to add a menu filter to all menus, use Ide.getMenubar().addMenuFilter().
