Hi - I have: (eval-when (:compile-toplevel :load-toplevel :execute) (defparameter *tcl-bindings* nil) (defun make-binding (tcl-event tcl-command-string) (let ((tcl-binding (conc$ "bind . " tcl-event " " tcl-command- string))) (pushnew tcl-binding *tcl-bindings*)))) (defun apply-bindings (&optional (bindings *tcl-bindings*)) (loop for binding in bindings do (format *debug-io* "Celtk: Applying binding ~S.~%" binding) (tk-format-now binding))) (defmacro defbinding (tcl-event tcl-command-string) `(eval-when (:compile-toplevel :load-toplevel :execute) (make-binding ,tcl-event ,tcl-command-string))) (defmacro define-binding-and-command (command tcl-event tcl-command- string) `(progn (defcommand ,command) (defbinding ,tcl-event ,tcl-command-string))) (define-binding-and-command double-click-1 "<Double-ButtonPress-1>" "{do-double-click-1 %W %K; break}") (define-binding-and-command double-click-2 "<Double-ButtonPress-2>" "{do-double-click-2 %W %K; break}") (define-binding-and-command double-click-3 "<Double-ButtonPress-3>" "{do-double-click-3 %W %K; break}") and have extended #'run-window to call #'apply-bindings. Trace output shows that the bindings are actually executed as expected. I also extended class tk-object to have appropriate slots: (defmodel tk-object (model) ((.md-name :cell nil :initform (gentemp "TK") :initarg :id) (tk-class :cell nil :initform nil :initarg :tk-class :reader tk- class) (timers :owning t :initarg :timers :accessor timers :initform nil) (on-command :initarg :on-command :accessor on-command :initform nil) (on-key-down :initarg :on-key-down :accessor on-key-down :initform nil :documentation "Long story. Tcl C API weak for keypress events. This gets dispatched eventually thanks to DEFCOMMAND") (on-key-up :initarg :on-key-up :accessor on-key-up :initform nil) (on-double-click-1 :initarg :on-double-click-1 :accessor on-double- click-1 :initform nil) ;; <<< --- here (on-double-click-2 :initarg :on-double-click-2 :accessor on-double- click-2 :initform nil) ;; <<< --- and here (on-double-click-3 :initarg :on-double-click-3 :accessor on-double- click-3 :initform nil) ;; <<< --- and here (user-errors :initarg :user-errors :accessor user-errors :initform nil) (tile? :initform t :cell nil :reader tile? :initarg :tile?)) (:documentation "Root class for widgets and (canvas) items")) From the code I am reading that if any of the slots on-double- click-1 ... is assigned a function this function gets called as soon as a double-click-n is received... Yet Celtk always delivers a normal ButtonPress event ... Do I need to extend #'widget-event-handle of Celtk to make this work? Kenny, did this ever work for you? Any ideas ? Thx!
