Re: [Paraview] pqViewManager in Clone2
I'm using Clone2 as a base for the application and it has:
...
...
PVMAIN_WINDOW_INCLUDE myMainWindow.h
GUI_CONFIGURATION_XMLS
${CMAKE_CURRENT_SOURCE_DIR}/ParaViewSources.xml
${CMAKE_CURRENT_SOURCE_DIR}/ParaViewFilters.xml
${CMAKE_CURRENT_SOURCE_DIR}/ParaViewReaders.xml
${CMAKE_CURRENT_SOURCE_DIR}/ParaViewWriters.xml
SOURCES ${ParaView_SOURCE_FILES}
)
in the CMakeLists.txt file. I want to use the open file routine used to
open any legal file type, but in code.
Thanks

That's because you haven't registered any readers with the reader
factory.
Look at:
http://www.paraview.org/Wiki/Writing_Custom_Applications#ParaViewReaders:_Reader_Factory_Configuration
You need to specify an XML with the names of the readers that your
applications wants to expose in the build_paraview_client() function
call.

There are no reader options available.
The program will need to load multiple file types so I want to use a
module
that can load any valid file type. Are the reader options loaded
automatically from ParaViewReader.xml? Is pqLoadDataReaction the correct
class for loading files?
Thanks!

Hello,
If you are creating a custom application which always has 4 render
windows, then I'd suggest not even using the pqViewManager.
Simply create the 4 views yourself and pack them into a QWidget using
a QGridLayout. For example, the following code can be used after a
server connection has been made to set up the 4 views.
QWidget* centralWidget = new QWidget();
mainWindow-setCentralWidget(centralWidget);
QGridLayout* gl = new QGridLayout(centralWidget);
for (int xx=0; xx 2; xx++)
{
for (int yy=0; yy 2; yy++)
{
pqRenderView* view = qobject_castpqRenderView*(
ob-createView(pqRenderView::renderViewType(), server));
gl-addWidget(view-getWidget(), yy, xx);
}
}

Is
this assumption correct?
I reference the pqViewManager with the following code:
this-Internals-MultiViewManager
the active view (I'm guessing the only view at this point is):
pqView* view =
this-Internals-MultiViewManager-getActiveView();
This problem is there are no public methods to split the frame in
pqViewManager. It is possible to get the pqMultiViewFrame:
pqMultiViewFrame * multiViewFrame =
this-Internals-MultiViewManager-getFrame(view);
I've tested this by:
multiViewFrame-setTitle(HELLO WORLD!);
and it works, but I've tried multiple tries to get the frame to split
without success. Any insight will help.
Thanks!

[Paraview] Application using Paraview library in C++
Hi all,
I am attempting to use paraview's library to visualize medical volumes in
an application I am building from scratch. The program is written in C++.
I am having a hard time finding adequate documentation (forums and examples)
that shows how to build an application that uses paraview's library in C++.
I have ran the example program BasicApp.cxx and it works, but it uses a
SphereSource. I am loading dicom images or .vtk images. When I edit the
code for BasicApp.cxx to load .vtk files I get an error after setting the
representation to volume. From reading similar problems on forums, I think
the problem pertains to colormaps and scalars, but I cannot find
documentation on how to fix this in C++. I'm including my code below. I
may be over complicating this, but any help is appreciated.
Thanks for your time!
using namespace std;
// our main window
class MainWindow : public QMainWindow
{
public:
MainWindow()
{
// automatically make a server connection
pqApplicationCore* core = pqApplicationCore::instance();
pqObjectBuilder* ob = core-getObjectBuilder();
pqServer* server = ob-createServer(
pqServerResource(builtin:));
// create a graphics window and put it in our main window
this-RenderView =
qobject_castpqRenderView*(ob-createView(pqRenderView::renderViewType(),
server));
this-setCentralWidget(this-RenderView-getWidget());
// create source and elevation filter
pqPipelineSource* source;
pqPipelineSource* elevation;
source = ob-createSource(sources, SphereSource, server);
// updating source so that when elevation filter is created, the
defaults
// are setup correctly using the correct data bounds etc.
vtkSMSourceProxy::SafeDownCast(source-getProxy())-UpdatePipeline();
QStringList files;
files.push_back(../brain.vtk);
pqPipelineSource *reader;
pqObjectBuilder *builder = core-getObjectBuilder();
reader = builder-createReader(QString(internal_sources),
QString(legacyreader), files, server);
pqDataRepresentation *repr =
ob-createDataRepresentation(reader-getOutputPort(0), this-RenderView);
if(repr){
vtkSMPropertyHelper(repr-getProxy(),
Representation).Set(vtkSMPVRepresentationProxy::VOLUME);
pqDisplayPolicy pqDisplayP = core-getDisplayPolicy();
repr-getProxy()-UpdateVTKObjects();
}
//elevation = ob-createFilter(filters, ElevationFilter, source);
// put the elevation in the window
//ob-createDataRepresentation(elevation-getOutputPort(0),
this-RenderView);
// zoom to sphere
this-RenderView-resetCamera();
// make sure we update
this-RenderView-render();
}
QPointerpqRenderView RenderView;
