disconnect siganls in qlistview header
Message 1 in thread
I want to disconnect all clicked signals coming from a Qheader and do
this:
QObject::disconnect(my_qlistview->header(), SIGNAL (clicked(int)), 0, 0
);
QObject::disconnect(my_qlistview->header(), SIGNAL (pressed(int)), 0, 0
);
QObject::disconnect(my_qlistview->header(), SIGNAL (released(int)), 0, 0
);
but when I press on a header, my list is still sorted, and that's
precisely what I want to forbid.
I know I can use setSorting(-1), but I don't want to do this because I
want to do the setSorting(...)
by myself in a PopupMenu.
Do I forgot something?

No, I want to (re)connect the click to open a PopupMenu.

You probably want something like
my_qlistview->header()->setClickEnabled( false );

I was really close to the correct answer. I use Qt2.3.2 and the right signal
to
disconnect is sectionClicked(int) which is supposed to be "obsolete" (see
Qt2.3.2 doc)
but which is used by a click on the header() of a QListView.
So many time lost for...
