;; qlset.lsp - example initialization of QLEADER settings
;; Frank Whaley Autodesk, Inc.
;; Two functions are included in this file:
;;
;; (acet-ql-get)
;; Returns an association list containing the current QLEADER
;; settings from the Named Object Dictionary.
;;
;; (acet-ql-get <alist>)
;; Sets the specified values for QLEADER settings from the given
;; association list. Returns an association list containing the
;; new values.
;;
;; These functions can be used to examine the current QLEADER
;; settings, or to initialize the setting before using the QLEADER
;; command. For example, to use splined leaders and framed text:
;;
;; (acet-ql-set '((65 . 1)(72 . 1)))
;;
;; Both functions use the following group codes to identify QLEADER
;; settings:
;;
;; 3: user arrowhead block name (default="")
;; 40: default text width (default=0.0)
;; 60: annotation type (default=0)
;; 0=MText
;; 1=copy object
;; 2=Tolerance
;; 3=block
;; 4=none
;; 61: annotation reuse (default=0)
;; 0=none
;; 1=reuse next
;; 62: left attachment point (default=1)
;; 63: right attachment point (default=3)
;; 0=Top of top line
;; 1=Middle of top line
;; 2=Middle of multiline text
;; 3=Middle of bottom line
;; 4=Bottom of bottom line
;; 64: underline bottom line (default=0)
;; 65: use splined leader line (default=0)
;; 66: no limit on points (default=0)
;; 67: maximum number of points (default=3)
;; 68: prompt for MText width (word wrap) (default=1)
;; 69: always left justify (default=0)
;; 70: allowed angle, first segment (default=0)
;; 71: allowed angle, second segment (default=0)
;; 0=Any angle
;; 1=Horizontal
;; 2=90deg
;; 3=45deg
;; 4=30deg
;; 5=15deg
;; 72: frame text (default=0)
;; 170: active tab (default=0)
;; 0=Annotation
;; 1=Leader Line & Arrow
;; 2=Attachment
;; 340: object ID for annotation reuse
