public class QVBoxLayout
The QVBoxLayout
class lines up widgets vertically. 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");First, we create the widgets we want in the layout. Then, we create the
QVBoxLayout layout = new QVBoxLayout(); layout.addWidget(button1); layout.addWidget(button2); layout.addWidget(button3); layout.addWidget(button4); layout.addWidget(button5); window.setLayout(layout); window.show();
QVBoxLayout
object and add the widgets into the layout. Finally, we call QWidget::setLayout()
to install the QVBoxLayout
object onto the widget. At that point, the widgets in the layout are reparented to have window as their parent. QHBoxLayout
