Problem with layout & size

[rubykhanh]

//GLOBAL VAR
QVBoxLayout *mainLayout = new QVBoxLayout();
//

ToDoList::~ToDoList()
{
}

ToDoList::ToDoList(QWidget *parent)
    : QMainWindow(parent)
{
    QWidget *centralWidget = new QWidget();
    setCentralWidget(centralWidget);
    // Layout 1b
    QHBoxLayout *bottomLayout = new QHBoxLayout();
    QTextEdit *textTask = new QTextEdit();
    QPushButton *newButton = new QPushButton("+");
    bottomLayout->addWidget(textTask,5);
    bottomLayout->addWidget(newButton,1);
    // Layout 0
    QVBoxLayout *centralLayout = new QVBoxLayout();
    centralWidget->setLayout(centralLayout);
    centralLayout->addLayout(mainLayout,10); // Layout 1a
    centralLayout->addLayout(bottomLayout,1); // Layout 1b
    //Size Policy Bottom Layout Widget
    //CONNECT
    connect(newButton, SIGNAL(clicked()), this, SLOT(newTask()));
}

void ToDoList::newTask()
{
    QGroupBox *groupBox = new QGroupBox();

    QTextEdit *text = new QTextEdit();
    QPushButton *doneButton = new QPushButton("V");
    QPushButton *removeButton = new QPushButton("X");
    QHBoxLayout *groupLayout = new QHBoxLayout();

    groupBox->setLayout(groupLayout);
    groupLayout->addWidget(text);
    groupLayout->addWidget(doneButton);
    groupLayout->addWidget(removeButton);

    mainLayout->addWidget(groupBox);
    //CONNECT
    connect(removeButton, SIGNAL(clicked()), this, SLOT(delTask()));
}

My problem:

• When i click newButton to add a groupBox, it will appear in center of mainLayout.
  If i add 2 groupBox, they will divide in 2part; 3groupBox will be 3 part.
• If i add groupBox by using newButton more than 5 times, my app will be split out of screen.

Help me :

• How to set groupBox position in layout as a listwidget
• How to add scrollbar to mainLayout.

What do you mean by "as a list widget"?

and have you tried QScrollArea? https://doc.qt.io/qt-5/qscrollarea.html

Hi and welcome to devnet,

Why do you have a global layout variable ?
