    Why not make them just Qt::ItemIsSelectable ?

    @SGaist said in Table Navigation with NoItemFlags:

    ItemIsSelectable

    because that does not work either. The behaviour stays the same as with NoItemFlags

      Can you provide a minimal compilable example that shows that behaviour ?

          @SGaist if you have the frozencolumn example in Qt Creator you can just add the following to main.cpp in order to make the last item non selectable:

          QStandardItem *newItem = new QStandardItem();
          newItem->setFlags(Qt::NoItemFlags);
          model->setItem(model->rowCount() - 1, model->columnCount() - 1, newItem);
          

          keep in mind that you have to have the item in the view to test this properly (maybe reduce the number of rows and cols to 3)

            Hi
            Try with
            newItem->setFlags( Qt::ItemIsSelectable|Qt::ItemIsEnabled );

              The problem here is that I don't want the selection.
              I just want the item to be ignored and the Home/End keys to work in that col/row

                Ok. well if last item on row is not at least Enabled it wont jump to last on end key.
                Home still works. ( to go back to first )
                It wont scan to find last that can be End key too, im afraid.
                So unless you can live with a tiny selection, im not sure you can make ignore them.

                  @mrjj hmm that's not really an option. If I was content with that I wouldn't have asked :)
                  I guess the complaining users just have to live with it, unless I work around that issue by overriding the whole navigation (which seems overkill for that)

                    Well the tiny selection rect is far less intrusive than full one. hence i asked.

                    You could try to fix the End key issue with scanning for
                    a new cell that can have focus. and handle that case your self and
                    else just call native keyhandling.

                      From what I can see in the code I would say Home is going to the first enabled + visible row but End or Ctrl+End goes simply to the last visible row / column without checking for enabled. Is this what you see?

                        Hi
                        Actually if last cell is not selectable and or enabled, then the end key do nothing.
                        Meaning it wont go to last cell (in row) that can have focus/ be selected.
