Hello Mirko,
Hi,
I was wondering if there is any way to tell OOo to stop loading a
document - i.e. XComponentLoader.loadComponentFromURL() - after starting
the operation?
I drive OOo from Java/Uno, but some documents can take a very long time
to load - see e.g.
http://www.openoffice.org/issues/show_bug.cgi?id=78118
and in some applications it would be better to cancel the operation
after a timeout and tell the user "sorry, this document is unsupported"
rather than make the user wait for several minutes.
You are right - it would be nice to have such feature in OOo ...
but currently OOo does not have such feature .-)
There are already interface supporting canceling of load requests.
css.frame.XFrameLoader and css.document.XFilter.
So it seams that only XComponentLoader needs some new functionality.
But - please dont forget that those cancel request must be supported
by the code implementing the interface. If e.g. the filter is blocked by
a system call nobody can cancel these request.
The only way I can think of is to terminate the OOo process. Anybody has
a better idea?
....
Solution a) XDesktop.terminate() wouldnt help. Because it finds the new
created frame used for the load request. And those frame hinder the
office on termination. So this API call will return "false".
Solution b) Kill the office hardly. Then you will trigger the mechanism
behind AutoRecovery and CrashSave. Also not an option to be used realy.
Seams you need the new interface
XComponentLoader2.cancelLoadComponentFromURL() .-)
Thanks
Mirko
Regards
Andreas
