QDialog* dialog = new QDialog(); QVBoxLayout* layout = new QVBoxLayout(dialog); QLabel* label = new QLabel("Hello World!", dialog); layout->addWidget(label);
QDialog* dialog = new QDialog(); QFormLayout* layout = new QFormLayout(dialog); QLineEdit* lineEdit = new QLineEdit(dialog); QSpinBox* spinBox = new QSpinBox(dialog); layout->addRow("Name:", lineEdit); layout->addRow("Age:", spinBox);This code creates a new QDialog window, sets its layout to a QFormLayout, creates a new QLineEdit widget and a new QSpinBox widget, adds the widgets to the layout, and labels them with "Name:" and "Age:" respectively. Overall, the QDialog layout is a powerful tool for designing and arranging widgets in QDialog windows in Qt. By using this layout manager, developers can easily create custom dialogs that match the look and feel of their applications.
