How to add stretchable spacer in Qtoolbar?

I want some of my toolbar actions appear left-bound and some right-bound. I Gtk I remember adding a stretchable (expandable) separator. How do I achieve that in Qt?

I use Qt Creator but I am not afraid of editing source, so either solution is greatly appreciated.

You can use an empty widget with automatic expanding, it works like the spacers you can use in Qt Designer:

tb = my_toolbar;

QWidget* empty = new QWidget();
empty->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Preferred);
tb->addWidget(empty);

tb->addWidget(otherWidget);
