QWebView not resizing correctly
===

I have a QMainWindow with a horizontal layout as central widget. The horizontal layout contains three widgets.
Here is the code:

    this.navigationTree=new NavigationTree();
    Browser browser = new Browser();
    this.clusteringPlot=new ClusteringPlot();
    QWidget centralWidget=new QWidget();
    QHBoxLayout layout=new QHBoxLayout();
    layout.addWidget(navigationTree);
    layout.addWidget(clusteringPlot);
    layout.addWidget(browser);
    centralWidget.setLayout(layout);
    this.setCentralWidget(centralWidget);`

where Browser is a QWebView.

Whenever I resize the main window Browser does not get resized while clusteringPlot(extends QWidget) and navigationTree(extends QTreeWidget) do.

How can I change my code so that also Browser get resized? I took a look at similar questions but I could not find a solution to my problem.

Thanks a lot in advance
