I take it you mean mean overriding the setSorting method ?? No? How else does
one "catch header clicks"? Overriding the setSorting method worked but seems a
little cludgy.

I am have been comparing ktablistbox with qlistview. I have a few concerns
about features I would like to enhance ktablistbox with, but don't know if
qlistview supports them.

1) Is there a method that will scroll the list to show another item as
long as the currently selected item isn't scrolled out of view. (For when new
mail is added to the currently selected folder).

2) Is there a method to set a background pixmap for a QListView.
setBackgroundPixmap doesn't seem to work and is deprecated anyway. If it is
possible can the background pixmap be tiled?

3) Is there a method to show icons in the header columns? Well that's a loaded
question I've been playing with the undocumented setColumnText function that
allows you to place an icon before the text. It's okay but limiting (what if I
want the icon after the text?)

I've only spent an hour or two looking at qlistview so there my be other things
too.

BFN,
Don.
