Wt

does not work:

WImage *img = new WImage("big.jpg");

WScrollArea *sc1 = new WScrollArea(root());

sc1->setMaximumSize(WLength("300px"), WLength("100px"));

sc1->setWidget(img);

WScrollArea *sc2 = new WScrollArea(root());

sc2->setMaximumSize(WLength("300px"), WLength("100px"));

sc2->setWidget(img);

WScrollBar::tie(sc1~~horizontalScrollBar(),sc2~~>horizontalScrollBar());
