Detailed Description

The CollapsingToolBar will change the QToolButton::toolButtonStyle of all added QToolButtons (via QAction or directly) depending on the total available width.

It was originally written as an answer to a StackOverflow question, and is not very sophisticated. Here is the usage example/test given in the SO question (find a suitable image file to use for an icon).

class MainWindow : public QMainWindow
{
    Q_OBJECT
  public:
    MainWindow(QWidget *parent = nullptr)
      : QMainWindow(parent)
    {
      QToolBar* tb = new CollapsingToolBar(this);
      tb->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
      tb->setAllowedAreas(Qt::TopToolBarArea | Qt::BottomToolBarArea);
      QIcon icon = QIcon(QPixmap(info_xpm));  // need an image here
      for (int i=0; i < 6; ++i)
        tb->addAction(icon, QStringLiteral("Action %1").arg(i));
      addToolBar(tb);
      show();
      // Adding another action after show() may collapse all the actions if the new toolbar preferred width doesn't fit the window.
      // Only an issue if the toolbar size hint was what determined the window width to begin with.
      //tb->addAction(icon, QStringLiteral("Action After"));
      // Test setting button style after showing (comment out the one above)
      //tb->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
      // Test changing icon size after showing.
      //tb->setIconSize(QSize(48, 48));
      // Try this too...
      //tb->setMovable(false);
    }
};
int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  //QApplication::setStyle("Fusion");
  //QApplication::setStyle("windows");
  MainWindow w;
  return app.exec();
