I am playing around with a Motif program which allows
URLs document titles etc. to be dragged around a
drawing area (kind of a pre-cursor to some graphical
overview/concept map). I've connected successfully to
Mosaic using the C CCI API, and sent URLs OK.
However, a problem arises when I "turn on" MCCISendAnchor,
to enable my GUI client to add newly selected URLs to its
display (or whatever). Firstly, Mosaic insists on returning
URLs which my client has sent it. I suppose this is
understandable, and it at least enables me to know
that my CallBack function (registered in MCCISendAnchor)
does work. However, as soon as I select an anchor in
Mosaic things go wrong: I don't get the usual message
at my client terminal window from MCCIHandleAddOutput,
and my GUI "hangs" the next time I select a URL with it.
From then on, the Mosaic to client sending of anchors
works fine, but my GUI only recovers (and processes
outstanding events) when I tell Mosaic to stop listening.
Any ideas?
