Detailed Description▲
This class is used to construct vertical box layout objects. See QBoxLayout for details.
The simplest use of the class is like this:
QWidget *window = new QWidget;
QPushButton *button1 = new QPushButton("One");
QPushButton *button2 = new QPushButton("Two");
QPushButton *button3 = new QPushButton("Three");
QPushButton *button4 = new QPushButton("Four");
QPushButton *button5 = new QPushButton("Five");
QVBoxLayout *layout = new QVBoxLayout(window);
layout->addWidget(button1);
layout->addWidget(button2);
layout->addWidget(button3);
layout->addWidget(button4);
layout->addWidget(button5);
window->show();First, we create the widgets we want to add to the layout. Then, we create the QVBoxLayout object, setting window as parent by passing it in the constructor; next we add the widgets to the layout. window will be the parent of the widgets that are added to the layout.
If you don't pass a parent window to the constructor, you can at a later point use QWidget::setLayout() to install the QVBoxLayout object onto window. At that point, the widgets in the layout are reparented to have window as their parent.
