Qt – Auto-expanding layout with Qt-Designer

layoutqtqt-designer

I'm using the Qt Designer.

I want to create a QVBoxLayout which will automatically expand to fill the whole window.

The layout of the QVBoxLayout remains fixed.

How can I cause the QVBoxLayout to expand and fill the entire window through the designer?

After creating your QVBoxLayout in Qt Designer, right-click on the background of your widget/dialog/window (not the QVBoxLayout, but the parent widget) and select Lay Out -> Lay Out in a Grid from the bottom of the context-menu. The QVBoxLayout should now stretch to fit the window and will resize automatically when the entire window is resized.

Qt Layout on QMainWindow

If you want to do it with code instead of using QtCreator, you could set the layout in a QWidget and then set the QWidget as the central widget of the main window like this:

#include <QtGui>
#include <QWidget>
#include <QHBoxLayout>
#include "mainwindow.h"

MainWindow::MainWindow() {  

        // Set layout
        QHBoxLayout *layout = new QHBoxLayout;
        layout->addWidget(myWidget1);
        layout->addWidget(myWidget2);

        // Set layout in QWidget
        QWidget *window = new QWidget();
        window->setLayout(layout);

        // Set QWidget as the central layout of the main window
        setCentralWidget(window);

}
