Detailed Description
This class is used to construct horizontal 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"); QHBoxLayout *layout = new QHBoxLayout; layout->addWidget(button1); layout->addWidget(button2); layout->addWidget(button3); layout->addWidget(button4); layout->addWidget(button5); window->setLayout(layout); window->show();
First, we create the widgets we want in the layout. Then, we create the QHBoxLayout object and add the widgets into the layout. Finally, we call QWidget::setLayout() to install the QHBoxLayout object onto the widget. At that point, the widgets in the layout are reparented to have window
as their parent.
