Hullo from Greg Bennett who is running under Clozure "Version
I am using the code from the CLIM 2.2.2 User Guide to get a window
(*test-frame*) and its
associated pane (*test-pane*).
Now I'm trying to set the position of the pointer in that pane. Once
I've done this, I can them
do things such draw-line from this position to another one.
As far as I can see I need to use the material in CH 15: Manipulating
the pointer in CLIM.
So I have done this:
(setf pprt (port-pointer (port *test-pane*))) -> #<CLIM-CLX::CLX-POINTER
(setf zpt (make-point 100 100))
Currently (pointer-position pprt) -> NIL
P283-4 suggests I should be able to do something like the following:
(pointer-set-position pprt 100 100) -> Evaluation aborted on
telling me that pointer-set-position in undefined.
(setf (pointer-position pprt) zpt) also returns an error: no method for
setf on pointer-position.
I poked about in the CLIM Spec to no avail, perhaps because my approach
is a wrong one.
Thx for any and all advice and assistance.
