State Comments
$GUI_CHECKED (1) Radio, Checkbox, MenuItem or ListViewItem will be checked.
$GUI_INDETERMINATE (2) Checkbox having the tristate attribute will be greyed.
$GUI_UNCHECKED (4) Radio, Checkbox, MenuItem or ListViewItem will be unchecked.
$GUI_DROPACCEPTED (8) Control will accept drop action : from file or from a drag of another control. See remarks.
$GUI_SHOW (16) Control will be visible. On Tabitem control will select the first tab to be displayed.
$GUI_HIDE (32) Control will not be visible.
$GUI_ENABLE (64) Control will be enabled.
$GUI_DISABLE (128) Control will be greyed out.
$GUI_FOCUS (256) Control will be given input/selected focus.
$GUI_DEFBUTTON (512) Control will be set as the default button on the window. See remark about TreeviewItems.
$GUI_EXPAND (1024) TreeViewItem will expand its child items.
$GUI_ONTOP (2048) Control will be have the ontop attribute for the window (zOrdering).
$GUI_NODROPACCEPTED (4096) Control will not accept drop action.
$GUI_NOFOCUS (8192) Listview control will loose focus.
$GUI_AVISTART (0) Avi control will start playing.
$GUI_AVISTOP (1) Avi control will stop playing.
$GUI_AVICLOSE (2) Avi control will stop playing and release resource.

State values can be summed up as for example $GUI_DISABLE (128) + $GUI_HIDE (32) sets the control in an disabled and hidden state.

If an AVI control has to be hidden with $GUI_HIDE (32) it should be closed with $GUI_AVICLOSE (1).

State of a "contextmenu" control cannot be changed.
State of a "listviewitem" control can be changed if the associated "listview" control has been created with an extended style $LVS_EX_CHECKBOXES. $GUI_FOCUS (256) and $GUI_NOFOCUS (8192) can be used on specific listviewitem provided listview control style allows to display it : $LVS_SHOWSELALWAYS.
State of a "menu or a ""menuitem" control cannot be hidden.

! Important information for $GUI_EXPAND: this state is only used for TreeViewItems. If you want to use this 'action' then at least 1 Sub-TreeViewItem has to exist/created under this item !
If you want to select another item in a TreeView then you can use $GUI_FOCUS (256) - the parent TreeView gets the window focus and the specified item is marked as selected.
If you want to set a treeview item as a default item which means painting it bold you can use $GUI_DEFBUTTON (512) - to turn it off just use another value but $GUI_DEFBUTTON (512), for instance 0. This state will not be returned by GUICtrlGetState().

If $GUI_DROPACCEPTED (8) is set to a visible control a drag & drop can be taken in account. The edit/input control will be set with the filename.
For other controls on reception of $GUI_EVENT_DROPPED, @GUI_DragId will return the controlID from where the drag start (-1 if from a file, @GUI_DragFile contain the filename being dropped) and @GUI_DropId returns the controlID of the dropped control.
Only dragging a ListviewItem will start the drag & drop process. The @GUI_DragId will be the ListView controlID.
