<div class="WordSection1">
<p class="MsoNormal">Just trying to play around with creating custom Paraview-based applications. I have compiled the examples that come with Paraview itself. Focusing on the ‘DemoApp1’ project, this is what the constructor for the main window looks like:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">myMainWindow::myMainWindow(QWidget* parentObject,<o:p></o:p></p>
<p class="MsoNormal"> Qt::WindowFlags wflags) : Superclass(parentObject, wflags)<o:p></o:p></p>
<p class="MsoNormal">{<o:p></o:p></p>
<p class="MsoNormal"> Ui::myMainWindow ui;<o:p></o:p></p>
<p class="MsoNormal"> ui.setupUi(this);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Make a connection to the builtin server<o:p></o:p></p>
<p class="MsoNormal"> pqApplicationCore* core = pqApplicationCore::instance();<o:p></o:p></p>
<p class="MsoNormal"> core->getObjectBuilder()->createServer(pqServerResource("builtin:"));<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Create render view<o:p></o:p></p>
<p class="MsoNormal"> pqRenderView* view = qobject_cast<pqRenderView*>(<o:p></o:p></p>
<p class="MsoNormal"> pqApplicationCore::instance()->getObjectBuilder()->createView(<o:p></o:p></p>
<p class="MsoNormal"> pqRenderView::renderViewType(),<o:p></o:p></p>
<p class="MsoNormal"> pqActiveObjects::instance().activeServer()));<o:p></o:p></p>
<p class="MsoNormal"> pqActiveObjects::instance().setActiveView(view);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Set it as the central widget<o:p></o:p></p>
<p class="MsoNormal"> this->setCentralWidget(view->widget());<o:p></o:p></p>
<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This strictly brings up a 3D render view in the window, no menus whatsoever, etc. That’s what I was looking for to start with. I wanted to hardcode loading a file next. Digging around a bit, I thought this would do the trick:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Load a file<o:p></o:p></p>
<p class="MsoNormal"> QStringList fileList;<o:p></o:p></p>
<p class="MsoNormal"> fileList.append("D:/data/my_datafile.vtu");<o:p></o:p></p>
<p class="MsoNormal"> pqLoadDataReaction::loadData(fileList);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems to find the file alright but it cannot seem to find a proper reader for the file. It pops up a dialog with the readers it could use and the list is empty.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So it seems I am clearly missing something… documentation for vtkSMReaderFactory suggests configuration through XML files. Not too sure how to go about that at this point… Is pqLoadDataReaction::loadData() too ‘high-level’ to use in something
as barebones as this example? Is there a better alternative at that point? Or if it is appropriate to use, what else does it require to be set in order to properly load a file?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance for your reply,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Charles <o:p></o:p></p>
