Hello,

I am trying to use CMUCL Motif interface to get a 'label gadget' to
display an image or a Pixmap.

I am trying the following

	(create-label-gadget
		parent
		"myLabelWithImage"
		:label-type :pixmap
		:label-pixmap
		(xlib:read-bitmap-file "filename.xbm"))

In this case I get a toolkit error like: IMAGE type not handled.
Fine, I then try

	(create-label-gadget
		parent
		"myLabelWithImage"
		:label-type :pixmap
		:label-pixmap
		(xlib:image-pixmap
		 (widget-window main-window)
		 (xlib:read-bitmap-file "filename.xbm")))

But, in this case I two kinds of error: the lisp side signals an error
like "Unknown type Pixmap", while the C side may signal "Warning: unknown
resource labelType".

Using 'set-values' does not seem to solve the problem either.

Has anybody tried anything similar?

Apologies for the informal description of the problem. My impression
is that the CMUCL/Motif interface does not handle at all images and
pixmaps (at least in the case of the label-gadget). But I do not have
too much time to track the problem down.

Thanks in advance for any help

Marco

   But, in this case I two kinds of error: the lisp side signals an error
   like "Unknown type Pixmap", while the C side may signal "Warning: unknown
   resource labelType".

The two errors are actually "Pixamp not handled" (Lisp side) and
"Unknown resource: labeType". The unknown resource can probably be
removed, but the bulk of the problem remains.

Thanks for any help
