Accessing the first data item from a IndexList.

[Bonafide]

Once again, that doesn't work..

Now, I'm getting a runtime error, as seen in the picture below. The selectedRows() function, doesn't return the complete row of the index selectd in the model (unless you select multiple columns in a specific row, and then just gets the first data item from the first selected cell), so I'm not sure if that has something to do with the error.

I've been trying to get this to work for quite some time today, but it's proving futile! I do appreciate the help, though, so don't think I don't!

The model that is being utilized in the program is named "model."

QVariant target;
 
 
    selectionModel = ui->taskView->selectionModel();
    QModelIndexList editIndex = selectionModel->selectedRows();
 
    target = model->data(model->index(editIndex.first().row(), 0));

QVariant target;


    selectionModel = ui->taskView->selectionModel();
    QModelIndexList editIndex = selectionModel->selectedRows();

    target = model->data(model->index(editIndex.first().row(), 0));

Edit: If I select the ENTIRE row, the code works, but that's not what I'm aiming for.

Will this work?

QModelIndexList QItemSelectionModel::selectedIndexes () const

QModelIndexList QItemSelectionModel::selectedIndexes () const

No, I tried that. selectedIndexes() only returns the index of the currently selected cell I believe, at least that's what I've assumed from testing it.

But if you have the index of the currently selected cell, you can get it's row, so it looks like "target = model->data(model->index(editIndex.first().row(), 0));" would then work.

Edit: Glad you got it working.

The problem was, selectedRows() or selectedIndexes() only returned the value of the selected cell(s); it does not return the indexes of all values in the row. So the QModelIndexList editIndex would only recieve the data from "NOTES" if it was the only cell selected. It would only work properly if the entire row was selected, thus returning the correct index and it's data. Otherwise, it only returned the data of the first index in editIndex, which may or may not of been what I wanted, and the rest of the code would then look for a value that never existed.

With what I did, I simply got the index of the the cell, then from that index, get the row value of the index (passed in the "row" parameter of model-index(row, column), and then specificied the column I wanted.

But once again, thanks for getting me on the right track. Your usage of of the index() function of model and .row(), got the juices flowin'.

Eureka!

This code successfully selects the first column of a row from any selected cell in said row, and returns it to a variable.

QVariant target;
 
selectionModel = ui->taskView->selectionModel();
 
QModelIndex in = selectionModel->currentIndex();
 
target = model->data(model->index(in.row(), 0));

QVariant target;

selectionModel = ui->taskView->selectionModel();

QModelIndex in = selectionModel->currentIndex();

target = model->data(model->index(in.row(), 0));

Many thanks, norobro, for getting me on the right track! You will be "thanked!"
