qtreeview item's data

[Pawello]

Hi,
I have a problem with QTreeView. I want to read QString from selected cell, or (starting) index of this cell but I dont know how to do it. I've tried to use currentIndex(), but it shows position in current View- no matter which item is on first place in window after sorting or filtering it's index is always 0,0.

Did you use QAbstractItemModel::data?

[Pawello]

this could help, but I dont know how can I use it to extract int value from e.g. 5. cell of selected row.

[spirit]

Using QVariant::toInt.

I've found this, but how to get data from e.g 5th. cell of the row.
E.g. No matter if I choose item at x,0 or x,1 I want to read data from x,5



And one more question: how can I make one header column invisible?

Use QAbstractItemModel::index to get necessary index. Then you can use it for getting data:

...
qDebug() << Q_FUNC_INFO << model->data(model->index(0, 5));
...

...
qDebug() << Q_FUNC_INFO << model->data(model->index(0, 5));
...

To copy to clipboard, switch view to plain text mode

See QHeaderView::hideSection.

I dont'understand what do you mean. I suppose that

data(model->index(0, 5))

data(model->index(0, 5))

To copy to clipboard, switch view to plain text mode 

will always give me data from index 0,5
My problem is that I want to use current index' row and set index column as 5- only column must be constant, row depends on the chosen cell.

See QHeaderView::hideSection.

Thanks, I used QTreeView::setColumnHidden

Did you try this?

...
QVariant value = model->data(model->index(view->currentIndex().row(), 5));
...

...
QVariant value = model->data(model->index(view->currentIndex().row(), 5));
...

It still doesn't work.
I have:

QTreeView tab;
QStandardItemModel model;
...
int s=tab->currentIndex().row();
int a=model->data(model->index(s,5)).toInt();
...

QTreeView tab;
QStandardItemModel model;
...
int s=tab->currentIndex().row();
int a=model->data(model->index(s,5)).toInt();
...

To copy to clipboard, switch view to plain text mode 

Working code, which needs selecting items in 5th column :

QTreeView tab;
QStandardItemModel model;
...
int a=tab->currentIndex().data().toInt();
...

QTreeView tab;
QStandardItemModel model;
...
int a=tab->currentIndex().data().toInt();
...

That's because the current index == (0, 0) or invalid.

So what should I do? I don't see any difference between my code and code posted by you previously, but it doesn't work properly.
