public class QHBoxLayout
- extends QBoxLayout
The QHBoxLayout class lines up widgets horizontally.
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.
