I don't get expected output in text browser

[NewLegend]

I Declare input_events * ptr_ie as a private member in Mainwindow class and remove ptr_ie declarations from your get_info and print function.
But
Does not print all of the contents linked list

See

class input_events 
{
        typedef struct input ie;
 
        public:
                ie *l;
                ~input_events();
                input_events();
                void add_ie(ie *p);
                void gener_ie(); 
                friend class Trajectoire;
};

class input_events 
{
        typedef struct input ie;

        public:
                ie *l;
                ~input_events();
                input_events();
                void add_ie(ie *p);
                void gener_ie(); 
                friend class Trajectoire;
};

To copy to clipboard, switch view to plain text mode 

And

class MainWindow : public QMainWindow
{
    Q_OBJECT
 
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    Ui::MainWindow *ui;
 
private slots:
    void GetInfo();
    void print();
 
private:
    input_events * ptr_ie;
 
};

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    Ui::MainWindow *ui;

private slots:
    void GetInfo();
    void print();

private:
    input_events * ptr_ie;

};

^^^^^^^^^^^^^^^^^^^^^^^
See private



And this a function

void MainWindow::print()
{
    //input_events * ptr_ie;
    ie * ine;
 
 
   for(ine=ptr_ie->l; ine; ine = ine->suiv)
   {
       QString resultString = "";
       ui->textBrowser->setText( ui->textBrowser->toPlainText() + resultString.setNum(ine->id) + " ");
   }
}

void MainWindow::print()
{
    //input_events * ptr_ie;
    ie * ine;


   for(ine=ptr_ie->l; ine; ine = ine->suiv)
   {
       QString resultString = "";
       ui->textBrowser->setText( ui->textBrowser->toPlainText() + resultString.setNum(ine->id) + " ");
   }
}

The problem is that does not print ALL linked list
