Randy,
My users are complaining that adding objects to the canvas is too
cumbersome. Currently, they have to drop the object within the visible
region and then drag and drop it to its final destination. Obviously, when
the visible region is fully populated, this becomes a challenge. Any ideas
here?
Thanks,
Felipe

Randy,
Here's a bit more info, in case I haven't made myself clear:
My users create their large diagrams in a step-down-and-to-the-right
fashion. The problem appears when they reach the bottom right hand corner of
their view. The area will already be populated and they have to drop the
object somewhere else and then reposition it by dragging it outside the
canvas where they can't see where it is going to fall (If this is not fully
clear I can create a movie of it and send it to you.)
It would be nice if when they reached the bottom right hand corner of the
screen, that the canvas would expanded itself and scrolled to show the newly
added space where they could add their object.
Also, as another issue, they expected to hold the mouse down while dragging
the object from the palette. This is what they are used to from other
similar programs. In our case, when we try that, an error message pops up
when you drop the object on the canvas.
Anyway, let me know if there is anything we can do here.
Thanks again,
Felipe

The simple solution would be to add a MarginBorder to the contents figure.
This margin would ensure that the scrollable region is always as large as
the diagrams contents, plus some amount. Combine this with existing
autoscroll function and you should be good to go.

Thanks Dan, I got it.
I tracked the problem to a missing handler in
LogicElementFactory::GetNewObject().
Much appreciated,
