Nesting Layouts

[gabor53]

Hi,
I have the following layout in a QScrollArea:

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

    QLabel *spacer = new QLabel;
    QLabel *test = new QLabel("Test");


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

    QFormLayout *layout = new QFormLayout(this);
    viewport->setLayout (layout);
    QHBoxLayout *boxlayout = new QHBoxLayout(this);

    layout->addRow (Title);//Adding the Title
    layout->addRow(spacer,spacer);
    layout->addRow(spacer,spacer);
    layout->addRow(spacer,spacer);
	boxlayout->insertItem (5,test); 

    layout->addRow (Label_ID,ID_Display); //Adding ID number
    layout->addRow (Label_Name,LineEdit_Name);//Adding Name

    QFormLayout *dialog_flayout = new QFormLayout(this);
    this->setLayout (dialog_flayout);
    this->layout ()->addWidget (scroll);
    this->show();

Where the line
boxlayout->insertItem (5,test);
is I need to add 4 widgets to the line instead of 2. How can I nest a QHBoxLayout into this row?
Thank you for your help.

QFormLayout::addRow() has an overload that accepts other QLayouts.

// Set up your horizontal layout of 4 widgets
auto rowOfFour = new QHBoxLayout;
rowOfFour->addWidget(new QLabel("One"));
rowOfFour->addWidget(new QLabel("Two"));
rowOfFour->addWidget(new QLabel("Three"));
rowOfFour->addWidget(new QLabel("Four"));

// Add the horizontal layout to your main layout
auto topLevelLayout = new QFormLayout;
topLevelLayout->addRow(rowOfFour);
