get children of a listview

? Offline

I wrote:

 int numero_children = _listView->children().count();
                QList<QString> list;


                for (int i=0; i<numero_children; i++)

                {

                QModelIndex mi3 = index.child(i,0);
                QVariant data_child = _listView->model()->data(mi3);
                QString data_c = data_child.toString();
                list.insert(i,data_child.toString());



              }

but list is empty

Hope you are talking about QListView. What are looking for here as children of QListView ? What is the expectation ?

@dheerendra I click on a dir:

 QModelIndex index = _listView->currentIndex();

and then I want find out what there is inside the dir...how must I write?

@vale88 Did you at least check the value of numero_children?

@jsulm

Inside the dir there is this, numero_children is 7, because it counts also the file inside Nuova cartella, but I want to see only this 4 children

@vale88 What I wanted to know is the value of numero_children after executing this line of code

int numero_children = _listView->children().count();

If list is empty then the for loop was not executed.

@jsulm numero_children = 7
but numero_children must be 4, because inside I have a dir and 3 files, the for loop is executed, but I think I write bad this line:

QVariant data_child = _listView->model()->data(mi3);

because data_child is invalid

@vale88

in debug I have this

@vale88

int numero_children = _listView->children().count();

The only possibility is the numero_children equals 0, check your _listView->children().
I think you just debug with put breakpoint int for cycle.
If it's impossible condition, check your funcation stack.Is there a stack overflow?

@Crawl.W I just done it, no because numero_children = 7
