QTableView Getting Selected Rows According To Selection Order
-
Hi all,
I have a question. I am using selectedrows method of the selection model of the QTableView.
However, selectedrows() does not return the selected row indexes in order.
For example, when I do multiselection with mousepress, at first I am selecting row 5, then row 4,3 and 2. However the method returns indexes like 2,3,4,5. I have to get the rows in 5,4,3,2.
I tried to use selectedindexes metod too, but I am getting an error like "Asert p in qsortfilterproxymodel.cpp in line 190". (Maybe there is a mapping problem in my custom model I do not know).
Is there anyone knowing the solution?

If by "selected row indexes in order" you mean "the order I actually did the selection clicks" then I'm pretty sure Qt infrastructure will not have recorded that --- why should it? If you really want that you'll have to write your own code to record the order. But that would be unusual --- I cannot think of an application which does so, the user can select-click in any order, all that matters is which rows end up selected.I tried to use selectedindexes metod too, but I am getting an error like "Asert p in qsortfilterproxymodel.cpp in line 190". (Maybe there is a mapping problem in my custom model I do not know).
That will be some error in your own code.

Thanks
So I implemented my custom ordering now as you suggested.
It would be good if Qt did this recording but no matter. It takes only 5 mins.
