* Object events
*
* The system AND apps generate these. The system generates these for

* apps generate them, apps put the has-meaning-to-the-app-only ID value
* in dwParam2.
* For all events, if you want detailed accessibility information, callers
* should
* * Call AccessibleObjectFromWindow() with the hwnd, idObject parameters
* of the event, and IID_IAccessible as the REFIID, to get back an
* IAccessible* to talk to
* * Initialize and fill in a VARIANT as VT_I4 with lVal the idChild
* parameter of the event.
* * If idChild isn't zero, call get_accChild() in the container to see
* if the child is an object in its own right. If so, you will get
* back an IDispatch* object for the child. You should release the
* parent, and call QueryInterface() on the child object to get its
* IAccessible*. Then you talk directly to the child. Otherwise,
* if get_accChild() returns you nothing, you should continue to
* use the child VARIANT. You will ask the container for the properties
* of the child identified by the VARIANT. In other words, the
* child in this case is accessible but not a full-blown object.
* Like a button on a titlebar which is 'small' and has no children.
*/
/*
* For all EVENT_OBJECT events,
* hwnd is the dude to Send the WM_GETOBJECT message to (unless NULL,
* see above for system things)
* idObject is the ID of the object that can resolve any queries a
* client might have. It's a way to deal with windowless controls,
* controls that are just drawn on the screen in some larger parent
* window (like SDM), or standard frame elements of a window.
* idChild is the piece inside of the object that is affected. This
* allows clients to access things that are too small to have full
* blown objects in their own right. Like the thumb of a scrollbar.
* The hwnd/idObject pair gets you to the container, the dude you
* probably want to talk to most of the time anyway. The idChild
* can then be passed into the acc properties to get the name/value
* of it as needed.
*
* Example #1:
* System propagating a listbox selection change
* EVENT_OBJECT_SELECTION
* hwnd == listbox hwnd
* idObject == OBJID_WINDOW
* idChild == new selected item, or CHILDID_SELF if
* nothing now selected within container.
* Word '97 propagating a listbox selection change
* hwnd == SDM window
* idObject == SDM ID to get at listbox 'control'
* idChild == new selected item, or CHILDID_SELF if
* nothing
*
* Example #2:
* System propagating a menu item selection on the menu bar
* EVENT_OBJECT_SELECTION
* hwnd == top level window
* idObject == OBJID_MENU
* idChild == ID of child menu bar item selected
*
* Example #3:
* System propagating a dropdown coming off of said menu bar item
* EVENT_OBJECT_CREATE
* hwnd == popup item
* idObject == OBJID_WINDOW
* idChild == CHILDID_SELF
*
* Example #4:
*
* For EVENT_OBJECT_REORDER, the object referred to by hwnd/idObject is the
* PARENT container in which the zorder is occurring. This is because if
* one child is zordering, all of them are changing their relative zorder.

*

/*
* NOTES:
* There is only one "focused" child item in a parent. This is the place
* keystrokes are going at a given moment. Hence only send a notification
* about where the NEW focus is going. A NEW item getting the focus already
* implies that the OLD item is losing it.
*
* SELECTION however can be multiple. Hence the different SELECTION
* notifications. Here's when to use each:
*
* (1) Send a SELECTION notification in the simple single selection
* case (like the focus) when the item with the selection is
* merely moving to a different item within a container. hwnd + ID
* is the container control, idChildItem is the new child with the
* selection.
*
* (2) Send a SELECTIONADD notification when a new item has simply been added
* to the selection within a container. This is appropriate when the
* number of newly selected items is very small. hwnd + ID is the
* container control, idChildItem is the new child added to the selection.
*
* (3) Send a SELECTIONREMOVE notification when a new item has simply been
* removed from the selection within a container. This is appropriate
* when the number of newly selected items is very small, just like
* SELECTIONADD. hwnd + ID is the container control, idChildItem is the
* new child removed from the selection.
*
* (4) Send a SELECTIONWITHIN notification when the selected items within a
* control have changed substantially. Rather than propagate a large
* number of changes to reflect removal for some items, addition of
* others, just tell somebody who cares that a lot happened. It will
* be faster an easier for somebody watching to just turn around and
* query the container control what the new bunch of selected items
* are.
*/
#define EVENT_OBJECT_STATECHANGE 0x800A // hwnd + ID + idChild is item w/ state change

* Examples of when to send an EVENT_OBJECT_STATECHANGE include
* * It is being enabled/disabled (USER does for windows)
* * It is being pressed/released (USER does for buttons)
* * It is being checked/unchecked (USER does for radio/check buttons)
*/
#define EVENT_OBJECT_LOCATIONCHANGE 0x800B // hwnd + ID + idChild is moved/sized item

* Note:
* A LOCATIONCHANGE is not sent for every child object when the parent
* changes shape/moves. Send one notification for the topmost object
* that is changing. For example, if the user resizes a top level window,
* USER will generate a LOCATIONCHANGE for it, but not for the menu bar,
* title bar, scrollbars, etc. that are also changing shape/moving.
*
* In other words, it only generates LOCATIONCHANGE notifications for
* real windows that are moving/sizing. It will not generate a LOCATIONCHANGE
* for every non-floating child window when the parent moves (the children are
* logically moving also on screen, but not relative to the parent).
*
* Now, if the app itself resizes child windows as a result of being
* sized, USER will generate LOCATIONCHANGEs for those dudes also because
* it doesn't know better.
*
* Note also that USER will generate LOCATIONCHANGE notifications for two
* non-window sys objects:
* (1) System caret
* (2) Cursor
