org.eclipse.ui.IActionBars

All known Subclasses:   org.eclipse.ui.SubActionBars,
IActionBars
public interface IActionBars (Code)
Used by a part to access its menu, toolbar, and status line managers.

Within the workbench each part, editor or view, has a private set of action bars. This set, which contains a menu, toolbar, and status line, appears in the local toolbar for a view and in the window for an editor. The view may provide an implementation for pre-existing actions or add new actions to the action bars.

In a workbench window there are a number of actions which are applicable to all parts. Some common examples are CUT, COPY and PASTE. These actions, known as "global actions", are contributed to the workbench window by the window itself and shared by all parts. The presentation is owned by the window. The implementation is delegated to the active part.

To participate in the global action design an IWorkbenchPart should register a handler for each global action which is implemented by the part. This can be done by calling setGlobalActionHandler. For convenience, the standard global actions are defined in org.eclipse.ui.IWorkbenchActionConstants.

Additional work is required for the Delete global action. In this case the accelerator is defined in the menu item text but is not hooked on the window. This is to support text editors where the Delete key is functional even when the Delete action is disabled (no text is selected). An implementation for this accelerator must be defined locally, in each part, by listening for Delete key events.

A part may also contribute new actions to the action bars as required. To do this, call getMenuManager, getToolBarManager, or getStatusLineManager as appropriate to get the action target. Add the action(s) to the target and call update to commit any changes to the underlying widgets.

This interface is not intended to be implemented by clients.





Method Summary
public  voidclearGlobalActionHandlers()
     Clears the global action handler list.
public  IActiongetGlobalActionHandler(String actionId)
     Returns the global action handler for the action with the given id.
public  IMenuManagergetMenuManager()
     Returns the menu manager.
public  IServiceLocatorgetServiceLocator()
     Returns the service locator for these action bars.
public  IStatusLineManagergetStatusLineManager()
     Returns the status line manager.
public  IToolBarManagergetToolBarManager()
     Returns the tool bar manager.
public  voidsetGlobalActionHandler(String actionId, IAction handler)
     Sets the global action handler for the action with the given id.
public  voidupdateActionBars()
     Updates the action bars.



Method Detail
clearGlobalActionHandlers
public void clearGlobalActionHandlers()(Code)
Clears the global action handler list.

Note: Clients who manipulate the global action list are responsible for calling updateActionBars so that the changes can be propagated throughout the workbench.




getGlobalActionHandler
public IAction getGlobalActionHandler(String actionId)(Code)
Returns the global action handler for the action with the given id.
Parameters:
  actionId - an action id declared in the registry an action handler which implements the action id, ornull if none is registered
See Also:   IWorkbenchActionConstants
See Also:   IActionBars.setGlobalActionHandler(String,IAction)



getMenuManager
public IMenuManager getMenuManager()(Code)
Returns the menu manager.

Note: Clients who add or remove items from the returned menu manager are responsible for calling updateActionBars so that the changes can be propagated throughout the workbench.

the menu manager



getServiceLocator
public IServiceLocator getServiceLocator()(Code)
Returns the service locator for these action bars. The locator is found by looking locally, and then ascending the action bar hierarchy. The service locator; never null.
since:
   3.2



getStatusLineManager
public IStatusLineManager getStatusLineManager()(Code)
Returns the status line manager.

Note: Clients who add or remove items from the returned status line manager are responsible for calling updateActionBars so that the changes can be propagated throughout the workbench.

the status line manager



getToolBarManager
public IToolBarManager getToolBarManager()(Code)
Returns the tool bar manager.

Note: Clients who add or remove items from the returned tool bar manager are responsible for calling updateActionBars so that the changes can be propagated throughout the workbench.

the tool bar manager



setGlobalActionHandler
public void setGlobalActionHandler(String actionId, IAction handler)(Code)
Sets the global action handler for the action with the given id.

Note: Clients who manipulate the global action list are responsible for calling updateActionBars so that the changes can be propagated throughout the workbench.


Parameters:
  actionId - an action id declared in the registry
Parameters:
  handler - an action which implements the action id, ornull to clear any existing handler
See Also:   IWorkbenchActionConstants



updateActionBars
public void updateActionBars()(Code)
Updates the action bars.

Clients who add or remove items from the menu, tool bar, or status line managers should call this method to propagated the changes throughout the workbench.
