The BonoboViewFrame is the container side control interface
for its attached remote BonoboView. The view frame can be
used to set the zoom factor on the embedded view using the
bonobo_view_freame_set_zoom_factor
function.
This function either covers or uncovers the View embedded in a
BonoboViewFrame. If the View is covered, then the embedded widgets
will receive no Gtk events, such as mouse movements, keypresses,
and exposures. When the View is uncovered, all events pass through
to the BonoboView's widgets normally.
view_frame :
A BonoboViewFrame object whose embedded View should be
either covered or uncovered.
covered :
TRUE if the View should be covered. FALSE if it should
be uncovered.
