|
|
* 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
