org.eclipse.jface.action
Interface IMenuManager

All Superinterfaces:

IContributionItem, IContributionManager

All Known Implementing Classes:

MenuManager, SubMenuManager

public interface IMenuManager

extends IContributionManager, IContributionItem

The IMenuManager interface provides protocol for managing contributions to a menu bar and its sub menus. An IMenuManager is also an IContributionItem, allowing sub-menus to be nested in parent menus.

This interface is internal to the framework; it should not be implemented outside the framework.

This package provides a concrete menu manager implementation, MenuManager.

Method Summary

void	addMenuListener(IMenuListener listener) Adds a menu listener to this menu.
IMenuManager	findMenuUsingPath(String path) Finds the manager for the menu at the given path.
IContributionItem	findUsingPath(String path) Finds the contribution item at the given path.
boolean	getRemoveAllWhenShown() Returns whether all items should be removed when the menu is first shown, but before notifying menu listeners.
boolean	isEnabled() Returns whether this menu should be enabled or not.
void	removeMenuListener(IMenuListener listener) Removes the given menu listener from this menu.
void	setRemoveAllWhenShown(boolean removeAll) Sets whether all items should be removed when the menu is first shown, but before notifying menu listeners.
void	updateAll(boolean force) Incrementally builds the menu from the contribution items, and does so recursively for all submenus.

Method Detail

addMenuListener

public void addMenuListener(IMenuListener listener)

Adds a menu listener to this menu. Has no effect if an identical listener is already registered.

Parameters:

listener - a menu listener

findMenuUsingPath

public IMenuManager findMenuUsingPath(String path)

Finds the manager for the menu at the given path. A path consists of contribution item ids separated by the separator character. The path separator character is '/'.

Convenience for findUsingPath(path) which extracts an IMenuManager if possible.

Parameters:

path - the path string

Returns:

the menu contribution item, or null if there is no such contribution item or if the item does not have an associated menu manager

findUsingPath

public IContributionItem findUsingPath(String path)

Finds the contribution item at the given path. A path consists of contribution item ids separated by the separator character. The path separator character is '/'.

Parameters:

path - the path string

Returns:

the contribution item, or null if there is no such contribution item

getRemoveAllWhenShown

public boolean getRemoveAllWhenShown()

Returns whether all items should be removed when the menu is first shown, but before notifying menu listeners. The default is false.

Returns:

true if all items should be removed when shown, false if not

isEnabled

public boolean isEnabled()

Returns whether this menu should be enabled or not.

Specified by:

isEnabled in interface IContributionItem

Returns:

true if enabled, and false if disabled

removeMenuListener

public void removeMenuListener(IMenuListener listener)

Removes the given menu listener from this menu. Has no effect if an identical listener is not registered.

Parameters:

listener - the menu listener

setRemoveAllWhenShown

public void setRemoveAllWhenShown(boolean removeAll)

Sets whether all items should be removed when the menu is first shown, but before notifying menu listeners.

Parameters:

removeAll - true if all items should be removed when shown, false if not

updateAll

public void updateAll(boolean force)

Incrementally builds the menu from the contribution items, and does so recursively for all submenus.

Parameters:

force - true means update even if not dirty, and false for normal incremental updating
