/**
* How it works.
* KActionCollection is an organizing container for KActions.
* KActionCollection keeps track of the information necessary to handle
* configuration and shortcuts.
*
* Focus Widget pointer:
* This is the widget which is the focus for action shortcuts.
* It is set either by passing a TQWidget* to the KActionCollection constructor
* or by calling setWidget() if the widget wasn't known when the object was
* initially constructed (as in KXMLGUIClient and KParts::PartBase)
*
* Shortcuts:
* An action's shortcut will not not be connected unless a focus widget has
* been specified in KActionCollection.
*
* XML Filename:
* This is used to save user-modified settings back to the *ui.rc file.
* It is set by KXMLGUIFactory.

/*
Three actionCollection conditions:
1) Scope is known on creation and KAccel object is created (e.g. KMainWindow)
2) Scope is unknown and no KAccel object is available (e.g. KXMLGUIClient)
a) addClient() will be called on object
b) we just want to add the actions to another KXMLGUIClient object
The question is how to do we incorporate #2b into the XMLGUI framework?
We have a KCommandHistory object with undo and redo actions in a passed actionCollection
We have a KoDoc object which holds a KCommandHistory object and the actionCollection
We have two KoView objects which both point to the same KoDoc object
Undo and Redo should be available in both KoView objects, and
calling the undo->setEnabled() should affect both KoViews
When addClient is called, it needs to be able to find the undo and redo actions
When it calls plug() on them, they need to be inserted into the KAccel object of the appropriate KoView
In this case, the actionCollection belongs to KoDoc and we need to let it know that its shortcuts
have the same scope as the KoView actionCollection
KXMLGUIClient::addSubActionCollection
Document:
create document actions
View
create view actions
add document actionCollection as sub-collection
A parentCollection is created
Scenario 1: parentCollection has a focus widget set (e.g. via KMainWindow)
A KAccel object is created in the parentCollection
A KAction is created with parent=parentCollection
The shortcut is inserted into this actionCollection
Scenario 1a: xml isn't used
done
Scenario 1b: KXMLGUIBuilder::addClient() called
setWidget is called -- ignore
shortcuts are set
Scenario 2: parentCollection has no focus widget (e.g., KParts)
A KAction is created with parent=parentCollection
Scenario 2a: xml isn't used
no shortcuts
Scenario 2b: KXMLGUIBuilder::addClient() called
setWidget is called
shortcuts are inserted into current KAccel
shortcuts are set in all other KAccels, if the action is present in the other KAccels
