Lines in Gridlayout are incorrectly positioned

Hi,
I have the following code which supposed to create subsequent lines in a Dialog:

	QWidget *mainWidget = new QWidget(this);

 QScrollArea *scroll = new QScrollArea(this);
        scroll->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn);
        scroll->setVerticalScrollBarPolicy (Qt::ScrollBarAlwaysOn);
        scroll->setFixedSize (885,710);


   //viewport

        QWidget* viewport  = new QWidget(this);
        scroll->setWidget (viewport);
        scroll->setWidgetResizable (true);

       QLineEdit *lineedit1 = new QLineEdit;
       QLineEdit *lineedit2 = new QLineEdit;
       QLineEdit *lineedit3 = new QLineEdit;
       QLineEdit *lineedit4 = new QLineEdit;
       QLineEdit *lineedit5 = new QLineEdit;
       QLineEdit *lineedit6 = new QLineEdit;

       lineedit1->setText ("LineEdit1");
       lineedit2->setText ("LineEdit2");
       lineedit3->setText ("LineEdit3");
       lineedit4->setText ("LineEdit4");
       lineedit5->setText ("LineEdit5");
       lineedit6->setText ("LineEdit6");

       lineedit1->setMaximumWidth (100);
       lineedit2->setMaximumWidth (100);
       lineedit3->setMaximumWidth (100);
       lineedit4->setMaximumWidth (100);
       lineedit5->setMaximumWidth (100);
       lineedit6->setMaximumWidth (100);

  // Gridlayout

       QGridLayout *grid = new QGridLayout;

       grid->addWidget (lineedit1,0,0,Qt::AlignTop);
       grid->addWidget (lineedit2,0,1,Qt::AlignTop);
       grid->addWidget (lineedit3,0,2,Qt::AlignTop);
       grid->addWidget (lineedit4,0,3,Qt::AlignTop);
       grid->addWidget (lineedit5,1,0,Qt::AlignTop);
       grid->addWidget (lineedit6,1,1,Qt::AlignTop);

      scroll->setLayout (grid);

        int colcount = grid->columnCount ();
        qDebug() << "Column count: " << colcount;

        int rowcount = grid->rowCount ();
        qDebug() << "Row count: " << rowcount;

        int columnwidth = grid->columnMinimumWidth (0);
        qDebug() << "1st column width: " << columnwidth;

  // VBox Layout

        QVBoxLayout* mainLayout = new QVBoxLayout;
        mainLayout->addWidget(title);


        mainLayout->addWidget(scroll);
        mainWidget->setLayout(mainLayout);
        mainWidget->show ();
}

The code generates the following dialog:

I'm wondering why is the second line on the bottom of the page? How can I get the widgets in the line closer to each other?
Thank you for your help.

Hi,

There's one thing that's wrong, you should not put a layout on a QScrollArea but a widget. So the first thing to do is put your grid layout on a widget and then set that widget on the QScrollArea.

IIRC the grid layout (as QVBoxLayout) will use by default the available space to layout the widget evenly
