public abstract class SystemBaseSubMenuAction

Our framework is designed to allow actions to be added to popup menus. Sometimes, we want an expandable or cascading menu item for an action. That is what this class is designed for. It represents a populated submenu.

Method Detail

setMenuID

public void setMenuID(
String Id)
Set the menu ID. This is important to allow action contributions via the popupMenus extension point.


setCreateMenuEachTime

public void setCreateMenuEachTime(boolean eachTime)
Call this if the submenu should be created on-the-fly every time, versus creating and populating it only on the first usage.


setPopulateMenuEachTime

public void setPopulateMenuEachTime(boolean eachTime)
Call this if the submenu should be populated on-the-fly every time, versus populating it only on the first usage. This only makes sense to be true if setCreateMenuEachTime is false.


setTest

public void setTest(boolean testMode)
Set test mode on


populateSubMenu

public abstract 
IMenuManager populateSubMenu(
IMenuManager menu)
Must be overridden

Example of this:


  menu.add(new MyAction1());
 

Parameters:
menu - The cascading menu, which is created for you. Add your actions to it.
Returns:
The given menu if you just populated it, or a new menu if you want to create the menu yourself.

getSubMenu

public 
IMenuManager getSubMenu()
Return the MenuManager object. It is this that is added to the primary popup menu.


createStandardGroups

protected void createStandardGroups(
IMenuManager menu)
Creates the standard groups for the context sub-menu.


getActions

public 
IAction[] getActions()
Return the actions currently in the menu. Never returns null, but may return an empty array.


createMnemonicsListener

protected 
ISystemViewMenuListener createMnemonicsListener(boolean setMnemonicsOnlyOnce)
Overridable method that instantiates the menu listener who job is to add mnemonics.

Parameters:
setMnemonicsOnlyOnce - true if the menu is static and so mnemonics need only be set once. False if it is dynamic
Since:
3.0 replaced SystemViewMenuListener by ISystemViewMenuListener

setShell

public void setShell(
Shell shell)
Sets the parent shell for this action. This is an override of our parent's method so we can cascade it to each sub-action.

Specified by:
setShell in interface ISystemAction
Overrides:
setShell in class SystemBaseAction

setSelection

public void setSelection(
ISelection selection)
This is called by the framework to set the selection input, just prior to showing the popup menu. We cascade this down to all of the actions added to this submenu.

Specified by:
setSelection in interface ISystemAction
Overrides:
setSelection in class SystemBaseAction
See Also:
SystemBaseAction.selectionChanged(SelectionChangedEvent event)

setViewer

public void setViewer(
Viewer v)
This is called by the framework to set the selection input, just prior to showing the popup menu. We cascade this down to all of the actions added to this submenu.

Specified by:
setViewer in interface ISystemAction
Overrides:
setViewer in class SystemBaseAction

getShell

public 
Shell getShell()
Return the shell. If not set locally, queries it from the submenu, which is where it is set by the RSE framework

Specified by:
getShell in interface ISystemAction
Overrides:
getShell in class SystemBaseAction

getSelection

public 
IStructuredSelection getSelection()
Return the selection. If not set locally, queries it from the submenu, which is where it is set by the RSE framework

Specified by:
getSelection in interface ISystemAction
Overrides:
getSelection in class SystemBaseAction

getViewer

public 
Viewer getViewer()
Return the viewer. If not set locally, queries it from the submenu, which is where it is set by the RSE framework

Specified by:
getViewer in interface ISystemAction
Overrides:
getViewer in class SystemBaseAction

setInputsFromSubMenuManager

public void setInputsFromSubMenuManager(
Shell shell,
                                        
Viewer v,
                                        
ISelection selection)
Special method called by our submenu manager when from its setInputs method. No need to cascade as the menu manager will do it for us.


setInputs

public void setInputs(
Shell shell,
                      
Viewer v,
                      
ISelection selection)
An optimization for performance reasons that allows all inputs to be set in one call. Intercept of parent so we can cascade to sub-actions. Note however this won't really ever get called. This is because for cascading menu actions we don't put this action object into the menumanager ... we put the SystemSubMenu object so that is what the SystemView will call.

Specified by:
setInputs in interface ISystemAction
Overrides:
setInputs in class SystemBaseAction

cascadeAllInputs

protected void cascadeAllInputs()
Called when actions added dynamically


setEnabled

public void setEnabled(boolean enable)
Enable/disable this menu action. This amounts to enabling/disabling the associated sub menu. Unfortunately, there is no way to do this!

Specified by:
setEnabled in interface IAction
Overrides:
setEnabled in class Action
