QWidget* widget = new QWidget(this); QVBoxLayout* layout = new QVBoxLayout(this); layout->addWidget(widget); setLayout(layout);
QWidget* widget = new QWidget(this); QHBoxLayout* layout = new QHBoxLayout(this); layout->addWidget(widget); layout->setAlignment(Qt::AlignCenter); setLayout(layout);
QWidget* widget = new QWidget(this); QHBoxLayout* layout = new QHBoxLayout(this); layout->addWidget(widget); setLayout(layout); ... layout->removeWidget(widget);In this example, we create a QHBoxLayout layout and add a QWidget to it using addWidget(). Then, we remove the widget from the layout using removeWidget(). Overall, QLayoutItem is a class that helps with managing the layout of widgets in Qt-based applications, and is part of the QtGUI module.
