CListCtrl中的向上和向下图标

Question

I have a CListCtrl with multiple columns, all of which are able to be sorted by. I would like to add up and down icons so that it is clear which column is currently sorted upon, and in which direction; much like Windows Explorer. My thought was to add a solid up/down arrow to the column name. I tried using the extended ASCII chars 30/31; but instead of showing the arrows, I got boxes (the "character not found" character); and using the unicode version, I got a question mark instead of the character.

Any suggestions as to how I could accomplish this?

Answer 1

You can use the newer CMFCListCtrl class or the CMFCHeaderCtrl class. There, you can set the sort column and the sort direction.

Try

myListCtrl.SetSortColumn(nCol, bAscending);

or

CMFCHeaderCtrl &headerCntrl = myListCtrl.GetHeaderCtrl();
headerCntrl.SetSortColumn(nCol, bAscending);
