Qt Designer: Unable to set default QToolBar area

Using the Qt Creator, it is impossible to specify the default tool bar area to be different from Qt::TopToolBarArea.

Steps to reproduce:

• Create new Qt Widgets application from Qt Creator
• Switch to designer
• Create one or more actions; drop them into the pre-generated tool bar
• Set allowed areas to Qt::LeftToolBarArea only (or Qt::LeftToolBarArea and Qt::RightToolBarArea only)

Result: the tool bar will still be in the top area when starting the application.

Details:

The UI compiler generates the following code:

toolBar->setAllowedAreas(Qt::LeftToolBarArea | Qt::RightToolBarArea);
toolBar->setOrientation(Qt::Vertical);
toolBar->setFloatable(false);
mainWindow->addToolBar(Qt::TopToolBarArea, toolBar);

I want to be able to specify the default area here, so that the last generated line can become something like:

mainWindow->addToolBar(Qt::LeftToolBarArea, toolBar);

Workaround

There is a workaround for this problem, which involves manual correction code from the main windows constructor:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    this->removeToolBar(ui->toolBar);
    this->addToolBar(Qt::LeftToolBarArea, ui->toolBar);
    ui->toolBar->show();
}
