[Interest] QGridLayout does not update

[Etienne Sandré-Chardonnal]

Ah, I think I got an idea from the docs.
Apparently, one cannot modify the layout of a widget after it has been set
as a QScrollArea content. Damned... this prevents me from dynamically
changing the content of the dock without recreating everything at each
update

Etienne

void QScrollArea::setWidget (
QWidget<qthelp://com.trolltech.qt.481/qdoc/qwidget.html>
 * *widget* )

Sets the scroll area's *widget*.

The *widget* becomes a child of the scroll area, and will be destroyed when
the scroll area is deleted or when a new widget is set.

The widget's autoFillBackground<qthelp://com.trolltech.qt.481/qdoc/qwidget.html#autoFillBackground-prop>
 property will be set to true.

If the scroll area is visible when the *widget* is added, you must
show()<qthelp://com.trolltech.qt.481/qdoc/qwidget.html#show>
 it explicitly.

Note that You must add the layout of *widget* before you call this
function; if you add it later, the *widget* will not be visible -
regardless of when you
show()<qthelp://com.trolltech.qt.481/qdoc/qwidget.html#show>
 the scroll area. In this case, you can also
notshow()<qthelp://com.trolltech.qt.481/qdoc/qwidget.html#show>
 the *widget* later.

*See also *widget<qthelp://com.trolltech.qt.481/qdoc/qscrollarea.html#widget>
().
