The line:
QLabel* mylabel = new QLabel( "Hello world" );

should actually be:
QLabel* mylabel = new QLabel( "Hello world", 0 );

(It's correct in the examples.tar file though)

The QTScribble project (and I presume others) won't compile under QT

An addition to the discussion of setStretchableWidget()

(insert the following after the first paragraph): If you don't
want one of your widgets stretched, but still want the toolbar
to occupy the whole width of the main window, you can add a
dummy QLabel with no text or image and make this the
stretchable widget. It will have no visual appearance of its
own but occupy the remaining space.
