I think Fl_Browser has the same issue for the same reason;
if the widget hasn't drawn itself yet, its internal variables
haven't yet been calculated.
Probably the thing to do is to split up the draw() code
so that the widgets internals can be pre-calculated
just before display()/show_item() run their effective code.
For now, I'd say you'd have to do what other apps do with
the other widgets that have this issue; wait until the widget
has been drawn before calling these methods.
There's a few ways to do this; timers, or making a small
event loop that calls Fl::wait() until the widget has been
draw()n, then you can make your calls to these methods
before returning to the regular event loop.
Perhaps the other devs can chime in on this,
as I can't remember all the ways this is normally handled.
