public class ActionBarAdvisor extends Object
Public base class for configuring the action bars of a workbench window.An application should declare a subclass of
ActionBarAdvisor
and override methods to configure a window's action bars to suit the needs of the particular application.The following advisor methods are called at strategic points in the workbench's lifecycle (all occur within the dynamic scope of the call to
PlatformUI.createAndRunWorkbench
):fillActionBars
- called afterWorkbenchWindowAdvisor.preWindowOpen
to configure a window's action bars
- Since:
- 3.1

ActionBarAdvisor
public ActionBarAdvisor(IActionBarConfigurer configurer)
Creates a new action bar advisor to configure a workbench window's action bars via the given action bar configurer.- Parameters:
configurer
- the action bar configurer
-
-
Method Detail
-
getActionBarConfigurer
protected IActionBarConfigurer getActionBarConfigurer()
Returns the action bar configurer.- Returns:
- the action bar configurer
-
fillActionBars
public void fillActionBars(int flags)
Configures the action bars using the given action bar configurer. Under normal circumstances,flags
does not includeFILL_PROXY
, meaning this is a request to fill the action bars of the corresponding workbench window; the remaining flags indicate which combination of the menu bar (FILL_MENU_BAR
), the tool bar (FILL_COOL_BAR
), and the status line (FILL_STATUS_LINE
) are to be filled.If
flags
does includeFILL_PROXY
, then this is a request to describe the actions bars of the given workbench window (which will already have been filled); again, the remaining flags indicate which combination of the menu bar, the tool bar, and the status line are to be described. The actions included in the proxy action bars can be the same instances as in the actual window's action bars. CallingActionFactory
to create new action instances is not recommended, because these actions internally register listeners with the window and there is no opportunity to dispose of these actions.This method is called just after
WorkbenchWindowAdvisor.preWindowOpen()
. Clients must not call this method directly (although super calls are okay). The default implementation callsmakeActions
ifFILL_PROXY
is specified, then callsfillMenuBar
,fillCoolBar
, andfillStatusLine
if the corresponding flags are specified.Subclasses may override, but it is recommended that they override the methods mentioned above instead.
- Parameters:
flags
- bit mask composed from the constantsFILL_MENU_BAR
,FILL_COOL_BAR
,FILL_STATUS_LINE
, andFILL_PROXY
-
makeActions
protected void makeActions(IWorkbenchWindow window)
Instantiates the actions used in the fill methods. Useregister(IAction)
to register the action with the key binding service and add it to the list of actions to be disposed when the window is closed.- Parameters:
window
- the window containing the action bars
-
register
protected void register(IAction action)
Registers the given action with the key binding service (by callingIActionBarConfigurer.registerGlobalAction(IAction)
), and adds it to the list of actions to be disposed when the window is closed.In order to participate in key bindings, the action must have an action definition id (aka command id), and a corresponding command extension. See the
org.eclipse.ui.commands
extension point documentation for more details.- Parameters:
action
- the action to register, this cannot benull
- See Also:
IAction.setActionDefinitionId(String)
,disposeAction(IAction)
-
getAction
protected IAction getAction(String id)
Returns the action with the given id, ornull
if not found.- Parameters:
id
- the action id- Returns:
- the action with the given id, or
null
if not found - See Also:
IAction.getId()
-
fillMenuBar
protected void fillMenuBar(IMenuManager menuBar)
Fills the menu bar with the main menus for the window.The default implementation does nothing. Subclasses may override.
- Parameters:
menuBar
- the menu manager for the menu bar
-
fillCoolBar
protected void fillCoolBar(ICoolBarManager coolBar)
Fills the cool bar with the main toolbars for the window.The default implementation does nothing. Subclasses may override.
- Parameters:
coolBar
- the cool bar manager
-
fillStatusLine
protected void fillStatusLine(IStatusLineManager statusLine)
Fills the status line with the main status line contributions for the window.The default implementation does nothing. Subclasses may override.
- Parameters:
statusLine
- the status line manager
-
isApplicationMenu
public boolean isApplicationMenu(String menuId)
Returns whether the menu with the given id is an application menu of the given window. This is used during OLE "in place" editing. Application menus should be preserved during menu merging. All other menus may be removed from the window.The default implementation returns false. Subclasses may override.
- Parameters:
menuId
- the menu id- Returns:
true
for application menus, andfalse
for part-specific menus
-
dispose
public void dispose()
Disposes this action bar advisor. Called when the window is being closed. This should dispose any allocated resources and remove any added listeners.The default implementation calls
disposeActions()
and releases menu manager. Subclasses may extend.
-
disposeActions
protected void disposeActions()
Disposes all actions added viaregister(IAction)
usingdisposeAction(IAction)
.
-
disposeAction
protected void disposeAction(IAction action)
Disposes the given action.The default implementation checks whether the action is an instance of
ActionFactory.IWorkbenchAction
and calls itsdispose()
method if so. Subclasses may extend.- Parameters:
action
- the action to dispose
-
saveState
public IStatus saveState(IMemento memento)
Saves arbitrary application-specific state information for this action bar advisor.The default implementation simply returns an OK status. Subclasses may extend or override.
- Parameters:
memento
- the memento in which to save the advisor's state- Returns:
- a status object indicating whether the save was successful
- Since:
- 3.1
-
restoreState
public IStatus restoreState(IMemento memento)
Restores arbitrary application-specific state information for this action bar advisor.The default implementation simply returns an OK status. Subclasses may extend or override.
- Parameters:
memento
- the memento from which to restore the advisor's state- Returns:
- a status object indicating whether the restore was successful
- Since:
- 3.1
