qtreeview item's data

[Pawello]

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 

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();
...

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.

What does "it doesn't work" mean? At this point no one can do anything for you beyond playing guessing games.

By the way, row and column numbering is 0-based, so if you are interested in the 5th column you will should use model->data(model->index(view->currentIndex().row(),4)).

[Pawello]

I know about starting numeration from 0.
When I'm using second code program works well and read pointed cell's info, no matter if view was sorted, filtered... but when I use first code it shows number depending on position of item in current view, not information from 5th column. It use current index of item instead of value from 5th column.

Try to debug your app. Or provide complete compilable code.
