Ok, rather than fetching the vtkTable's data directly I read out the "Row
Id" of the selected row in my SpreadSheetView. This is done by connecting to
the "pqView::selected (pqOutputPort* opp)" signal to my slot "pqMyPanel::
selectionChanged(pqOutputPort* opp)". The slot read the specific "IDs":
void pqMUDIIPanel::selectionChanged(pqOutputPort* opp)
{
if (opp)
{
vtkSMSourceProxy *activeSelection = opp->getSelectionInput();
if(activeSelection)
{
vtkSMVectorProperty* vp =
vtkSMVectorProperty::SafeDownCast(
activeSelection->GetProperty("IDs"));
QList<QVariant> ids = pqSMAdaptor::getMultipleElementProperty(vp);
if(!strcmp(activeSelection->GetXMLName(),
"CompositeDataIDSelectionSource"))
{
this->SelectedRowId = ids.at(2).toInt();
}
}
}
}
The "Row Id" can be used to work within the table on pure VTK-level via
proxy properties. Hope this could help someone with a similar question.
Cheers,
Stephan

Betreff: Fetching selection from SpreadSheet
Hello,
I use the SpreadSheetView to visualize a vtkTable. Now I want to fetch the
data of the row which is currently selected.
Right now I can connect to a selection event but have no idea to obtain the
slected data row.
pqSpreadSheetView *ssv = qobject_cast<pqSpreadSheetView*>(view);
QWidget *widget = ssv->getWidget();
QObject::connect(
ssv->getViewModel(), SIGNAL(selectionChanged(const QItemSelection&)),
this, SLOT(spreadSheetSelectionChanged(const QItemSelection&)));
When my slot is called, QItemSelection is empty.
Cheers,
Stephan
