[Java-gnome-developer] signal questions

[Lars W. <la...@di...>]

Hi everyone!

Two questions related to signals/listeners:

1) What am I supposed to do if I want to get notified of position
changes of the handle in a Paned widget?  Connecting handlers to the
check_resize, move_handle or accept_position signals in Glade doesn't
seem to work here and neither does adding a ContainerListener that tests
for CHECK_RESIZE events.

2) For TreeSelections, does anyone know of a clean way to get more
detailed information on what kind of user action changed the selection
(that is, in addition to the fact *that* it changed)?  The problem is
that I'd like to differentiate between replace actions (simple click)
and add/remove actions (Ctrl-click).  (Comparing the selection after
each change wouldn't always work since I need to differenciate the two
actions even in situations where there was previously no item selected.)
Is manually testing whether the Control-key was pressed during selection
the only/correct way to do it?

Thanks in advance for any suggestions!

Regards,
Lars
