I'm making a program that make calculation and try to integrate some Paraview
stuff, every things goes fine, I have my render from the server, but when I use
pqColorScaleEditor, the dialog show himself, I can change color depending on
scale but when I check the legend checkbox, the application crash and I have no
idea why ...
Part of my code :
void Widget3D::show_color_editor(){
scaleEdit = new pqColorScaleEditor(m_RenderView->getWidget());
pqDataRepresentation* repr = m_input->getRepresentation(m_RenderView);
scaleEdit->setRepresentation(repr);
scaleEdit->show();
}
void Widget3D::createView(){
if(m_server){
// create a graphics window and put it in our main window
this->m_RenderView = qobject_cast<pqRenderView*>(
m_object_builder->createView(pqRenderView::renderViewType(),
m_server));
if(m_RenderView){
m_layout_v->insertWidget(0,this->m_RenderView->getWidget());
}else{
//NLog::globalLog()->addError("Problem when creating a
RenderView.");
}
}else{
//NLog::globalLog()->addError("Cannot create RenderView if no
paraview server connection is set.");
}
}
void Widget3D::showRender()
{
if(m_source){
m_input = m_source;//m_filter2;
m_object_builder->createDataRepresentation(m_input->getOutputPort(0),
this->m_RenderView);
changeStyle();
pqDataRepresentation* repr =
m_input->getRepresentation(m_RenderView);
this->m_color->setRepresentation(m_input->getRepresentation(m_RenderView));
//this->scaleEdit->setRepresentation(m_input->getRepresentation(m_RenderView));
qDebug() << repr->getLookupTable();
//m_RenderView->get
qDebug() << repr->getLookupTableProxy();
// zoom to object
this->m_RenderView->resetCamera();
// make sure we update
this->m_RenderView->render();
}else{
//NLog::globalLog()->addError("There is no file to render.");
}
}
Widget3D::Widget3D(QWidget *parent) :
QWidget(parent)
{
// automatically make a server connection
m_core = pqApplicationCore::instance();
m_object_builder = m_core->getObjectBuilder();
// Register ParaView interfaces.
m_plugin_manager = m_core->getPluginManager();
// adds support for standard paraview views.
m_plugin_manager->addInterface(new
pqStandardViewModules(m_plugin_manager));
createView();
showRender();
connect(m_show_color_palet,SIGNAL(released()),this,SLOT(show_color_editor()));
}
You'll notice that I use client - server paraview architecture. What is strange
is that I have no problem seting color on my mesh but the legend make the
application crash.
I tryed different things like :
scaleEdit = new pqColorScaleEditor(m_RenderView->getWidget());
scaleEdit->show();
=> it show me that there is no map ta set the legend... So I think it
found the map
Maybe the problem is that the rendering is made in server side, but I did not
have problems with "pqDisplayColorWidget" that also use pqDataRepresentation.
Thanks for any idea, if you need the full code I can provide it.
