[Paraview-developers] Custom Applications / Manual Selection

[Mathieu Westphal]

Hello

I'm trying, in my custom application, to track selection in a specific view
and select point on another view consequently.
By "selecting" i mean : render it in a different color in renderview,
highligth it in spreadsheet view and display it in FindData widget "current
selection" field

I'm able to catch selected signal and extractt the selected cells numbers.
However i am not able to manually select anything.

I have try to copy the code used in the FindData widget and i've come up
with the following code , wich is suposed to select the cell with id==0,
how ever it is not working,
it clears the current selection but doesn't select anything :
[code]
    //!!!!!!!!!!!!!!!!!!!! SELECTION ? NOT WOKRING !!
    // Find the proper Proxy manager
    vtkSMSessionProxyManager* pxm =

vtkSMProxyManager::GetProxyManager()->GetActiveSessionProxyManager();

    // Create a new selection source
    vtkSMProxy* selSource = pxm->NewProxy("sources",
            "SelectionQuerySource");

    vtkSMPropertyHelper(selSource, "FieldType").Set( vtkSelectionNode::CELL
);

    selSource->UpdateVTKObjects();

    QString query;
    query = "%1 == %2";
    query = query.arg("id", "0");
    vtkSMPropertyHelper(selSource,
"QueryString").Set(query.toAscii().constData());
    printf("query : %s \n",query.toAscii().constData());
    selSource->PrintSelf(std::cout, vtkIndent(0));


this->reader->getOutputPort(0)->setSelectionInput(vtkSMSourceProxy::SafeDownCast(selSource),
0);
    pqSelectionManager * selman =
qobject_cast<pqSelectionManager*>(pqApplicationCore::instance()->manager("SELECTION_MANAGER"));
    selman->select(this->reader->getOutputPort(0));
    this->reader->getOutputPort(0)->renderAllViews( true );
[/code]

any idea or pointer about how to achieve that ?

Thanks

Mathieu
