Qt - QTableView - Clickable button in table row


I require a button/link within a table row of a QTableView. This is to open a dialog to allow that row to be edited more efficiently.

After hours of looking on the web I am yet to find a decent example.

I am aware that this is likely to be done using a QItemDelegate, but I am unsure how to have a functional widget within the row without forcing the item into edit mode first.

Any help would be greatly appreciated.


Solution

  • You could emulate the functionality of a link by underlining the clickable text, then capturing the cell click via the cellClicked(row, col) signal and check that col == editColumn. Then row would correspond to which item you are editing.

    For example,

    Data Name | Value 1 | Value 2 | Edit

    connect (tableWidget, SIGNAL(cellClicked(int,int)), this, SLOT(editSlot(int, int)));
    
    ...
    
    void ClassName::editSlot(int row, int col){
      if (col == 3) {
        doWork(row);
      }
    }
