A common
A common mistake when designing user interfaces with \QD is overlooking the
top level widget's layout. Unlike sub-layouts, which \QD displays with a
red border, top level layouts have no graphical representation. Layouts are
necessary for top level widgets, in this case QWidget, to ensure that when
the window is resized, the widgets on the form will resize accordingly. You
can try this out by pressing \key{Ctrl+R} now. To correct it, simply click
anywhere on the form and select \gui{Lay out Horizontally} or
\gui{Lay out Vertically}. The output will be the same. Now your widgets
will resize correctly.
