QScrollArea with Qwt3dPlot

[locke]

Hi,

I know that there are a lot of threads related to QScrollArea, but I'm can't find the solution to my problem. I want to show a QWt3DPlot (SurfacePlot) inside a Dock. In way that if you zoom the graph, then the scroll bars are shown, and let you move through the graph.

The code is:



SurfacePlot *my3dPlot = new SurfacePlot(this);

QVBoxLayout * m_layoutForWidget = new QVBoxLayout(my3dPlot);
m_layoutForWidget->setAlignment(Qt::AlignTop);

QScrollArea * myscroll3d = new QScrollArea;

myscroll3d->setWidgetResizable(true);
myscroll3d->setWidget(my3dPlot);

//my3dDock was previously defined and initilized
my3dDock->setWidget(myscroll3d);


But It doesn't work, any idea please??

Thanks!
