#includeIn this example, we create a new QVBoxLayout object to represent a vertical layout. We then create a QLineEdit object and assign the text "Type something here" to it. Finally, we add the line edit to the layout using the addWidget() function. Both of these examples are using the Qt library package.#include QVBoxLayout *layout = new QVBoxLayout; QLineEdit *lineEdit = new QLineEdit("Type something here"); layout->addWidget(lineEdit);
