/**
* How it works.
* TDEActionCollection is an organizing container for TDEActions.
* TDEActionCollection 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 TDEActionCollection 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 TDEActionCollection.
*
* 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 TDEAccel object is created (e.g. TDEMainWindow)
	2) Scope is unknown and no TDEAccel 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 TDEAccel 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 TDEMainWindow)
	A TDEAccel object is created in the parentCollection
	A TDEAction 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 TDEAction 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 TDEAccel
		shortcuts are set in all other TDEAccels, if the action is present in the other TDEAccels
*/

/*
shortcut may be set:
	- on construction
	- on plug
	- on reading XML
	- on plugAccel (deprecated)

On Construction: [via initShortcut()]
	insert into TDEAccel of m_parentCollection,
		if tdeaccel() && isAutoConnectShortcuts() exists

On Plug: [via plug() -> plugShortcut()]
	insert into TDEAccel of m_parentCollection, if exists and not already inserted into
