[Qt-interest] Call slot with default argument

[Justus Best]

Hi folks,

After some google-research I came across an old list entry
http://lists.trolltech.com/qt-interest/2003-06/thread00306-0.html
from 2003.
My question is if there is an solution for that Problem by now. I can't
find anything like that in the docs, but maybe I'am only looking for the
wrong terms.

To give a minimal explanation of my Problem without reading the old list
entry; I have two actions to sort a ListWidget ascending and descending
and I don't want to maintain two differnent slots for this. So I have a
slot like void sortList( Qt::SortOrder order ) which calls the Lists
sortItems function. If I now try to connect the triggert signal of my
action with this slot it fails because of unmatching parameters. It
would be easy to call connect with
action1...SLOT(sortList(Qt::AscendingOrder)) and action2 with
SLOT(sortList(Qt::DescendingOrder)). But that isn't possible so I have
to implement either two sort slots like sortListAsc and sortListDes, or
if the sortList slot is more complex I have to add two wrapper slots to
which call sortList with the right parameter.

My question is if there is a better solution for Problems like that.
