QTableView default selection

nammidd

By default, how to select the first row in QTableView with QFileSystemModel? When i use table->selectRow(0) it selects nothing, when i use QObject::connect(model, &QFileSystemModel::directoryLoaded, [&]{table->selectRow(0);}); it selects fourth row.
But if i use table->selectRow(0) in events (void keyPressEvent(QKeyEvent *event) for example), it works ok, what is the problem?

Hi,

Did you check the path returned by directoryLoaded ? Is it the one you expect ?

In any case, I'd use the model's index method to get the row corresponding to the loaded path.

table->selectionModel()->select(table->model()->index(0,0),QItemSelectionModel::ClearAndSelect);

@SGaist Hot to check the path returned by directoryLoaded? Where does it returns the path?
@VRonin It does not work. Selects nothing.

SGaist

It's given in parameter of the 'directoryLoaded' signal.

The problem is solved, it seems that QTableView performs sorting after directory loaded.
Is there a way to prevent sorting?

What about http://doc.qt.io/qt-5/qtableview.html#sortingEnabled-prop ?

@JonB This option only allows to change sorting order (from ascending to descending or vice versa), by clicking on the column header. But the sorting is done anyway, regardless of whether the option is turned on or off.

@nammidd ,
I think you can use setting false to setSortingEnabled.
For this you can use this link .
