Not sure how that would be possible from the QgsCollapsibleGroupBox
class, since the custom groupbox could be placed anywhere, not just in
a scroll area. What Leyan is suggesting (I think) would have to be
some slot in the dialog's class that catches the signal when one of
its children collapsible groupboxes is expanded, then figures the
current scroll position of the groupbox and how much of it is hidden,
then scrolls appropriately to expose the whole groupbox.

This would be somewhat similar to toolbox behavior, though without the
horrible 'hide everything else' aspect of that widget. A nice feature
to have, but probably a pain to add to many dialogs... unless we
create a custom Designer plugin scroll area class with such a slot so
that the signal of every collapsible groupbox it contains could be
assigned to it in Designer. The QgsCollapsibleGroupBox class would
also have to be a QtDesigner plugin, which Etienne has already worked
on.

Regards,

Larry
