;;; Commentary:

;; This file implements a debugging toolbar for IDLWAVE.  It requires
;; Emacs or XEmacs with toolbar and xpm support.

;; New versions of IDLWAVE, documentation, and more information
;; available from:
;;                 http://idlwave.org


;;; Code:

(eval-when-compile (require 'cl))

(defun idlwave-toolbar-make-button (image)
  (if (featurep 'xemacs)
      (toolbar-make-button-list image)
    (list 'image :type 'xpm :data image)))

(defvar default-toolbar)
(if (not (or (and (featurep 'xemacs)                ; This is XEmacs
		  (featurep 'xpm)                   ; need xpm
		  (featurep 'toolbar))              ; ... and the toolbar
	     (and (not (featurep 'xemacs))          ; This is Emacs
		  (boundp 'tool-bar-button-margin)   ; need toolbar

		  (image-type-available-p 'xpm))    ; need xpm
