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.
