如何在 QTreeView 中删除选定的行？

Question

I tried to delete a selected row of a QTreeView with an event. This is the function:

bool TargetEventFilter::deleteselect(bool delete)
{
    auto select= examplemodel->selectionModel()->currentIndex();
    auto parent= select.parent();
    int row= select.row();
    bool remove = examplemodel->model()->removeRow(row, parent);
    return remove ;
}

So my problem is: The event is working (tried with the debugger).The Parent and the indext is always right. But the problem is that the selected row will not be deleted. In "return remove" i get a "false".

why you do not used CurrentIndex ?

 bool remove = examplemodel->model()->removeRow(row, select);
