; NAME:
;	qImage_cw_state__define
; PURPOSE:
;	Defines the state structure for the qImage_cw compound widget
; CATEGORY:
;	Compound widget qImage_cw
; CALLING SEQUENCE:
;	state = {qImage_cw}
; INPUTS:
;	parent			scalar; type: long integer
;						ID of the parent widget
; OUTPUTS:
;	(state structure)
; INCLUDE:
	@compile_opt.pro			; On error, return to caller
; PROCEDURE:
;	The fields in the state structure are explained in href=qImage_cw= (compound widget)
; MODIFICATION HISTORY:
;	JAN-2000, Paul Hick (UCSD/CASS)
;	JAN-2003, Paul Hick (UCSD/CASS)
;		Changed structure elements img_size and img_offset from short to long integer.
;		The short integer caused problems for large zoom factors: zoom*img_size gets very big.
;		Added wid_smeimask.
;	NOV-2003, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
;		Added wid_corner
;-

; State structure
; The state structure is stored as user value to the first child widget.
; If the ID of the root widget is known the state can be retrieved by
;
;	wid_child = widget_info( id_root, /child)
;	widget_control, wid_child, get_uvalue=state
;
; The state consits of:
;	- the widget id of all widgets making up the compound widget
