[SAIL-Dev] Re: Preview project not working

[Aaron Unger]

What OTrunk displays depends on what is returned in the getComponent() method in the view associated with an OTObject. OTrunk will automatically call getComponent() on the first child of the otrunk/root element in the otml. It is up to that element's view to render/ignore any children OTObjects. The view <-> object relationships are defined in the otml -- in this case, since the root OTObject is an OTPasProject, the view that will be displayed is the OTPasProjectView.  It looks like this view is set to instantiate the PasProject object via the controller, and then display a new JLabel("Loading Pas project, " + pasProject.getTitle())... which is what you're seeing. I just checked in a change to the view to where it grabs the frame from the PasProject, calls showFrame(), and then hides the frame that pops up. It then grabs the main contentPane from the frame and returns that. This seems to work, but it seems kludgey to have to render/hide the PasFrame (it wouldn't show anything without doing that). It will give you a starting point at least. Update your pas-otrunk project and give it a shot. :-) -- Aaron Geoffrey Kwan wrote: Awesome, I've made a little bit of progress using your help. I now run the code below and the popup window displays and the text within it says "Loading Pas project, Project Title". The window just stays like that and never changes though. Clicking in the window does nothing.         PasProject pasProject = (PasProject) rootBean;         otViewerHelper.loadOTrunk(otDb, pasProject.getProjectFrame());         JDialog popup = new JDialog();         JPanel panel=new JPanel(new BorderLayout(5, 5));         OTViewContainerPanel otPanel = null;         OTFrameManager frameManager =             (OTFrameManager) viewContext.getViewService(OTFrameManager.class);         otPanel = new OTViewContainerPanel(frameManager);         otPanel.setTopLevelContainer(true);         OTViewFactory viewFactory = viewContext.createChildViewFactory();         otPanel.setOTViewFactory(viewFactory);                 panel.setLayout(new BorderLayout());         otPanel.setCurrentObject(otrunkRoot);         panel.add(otPanel, BorderLayout.CENTER);         popup.add(panel);         popup.setVisible(true); Is there something else I need to call to get it moving along past the "Loading Pas project, Project Title" screen?

The jpanel passed in is just used so that popup error messages are correctly centered on which ever jpanel the caller prefers. To actually display something you will need to do a few more steps. If you look at the getComponent method of the OTrunkStep you can see the remaining steps.  That method is doing other stuff to so I'll try to pick out just what you need.  It would be really nice to have an example class that does just these steps inside of the OTrunk project somewhere.  This code doesn't deal with loading in learner data or setting up a view mode. ----------- JPanel panel=new JPanel(); OTDatabase otDB = viewerHelper.loadOTDatabase(getAuthoredDataURL()); viewerHelper.loadOTrunk(otDB, panel); OTObject root = viewerHelper.getRootObject(); OTViewContainerPanel otPanel = viewerHelper.createViewContainerPanel(); panel.setLayout(new BorderLayout()); panel.add(otPanel, BorderLayout.CENTER); otPanel.setCurrentObject(root); ---------- Scott Geoffrey Kwan wrote: > I still can't get preview project to display any content. > > In OTrunkCurnit.java I have tried calling > >         otViewerHelper.loadOTrunk(otDb, pasProject.getProjectFrame()); > > and also subsequently tried > >         otViewerHelper.loadOTrunk(otDb, > pasProject.getProjectFrame().getContentPane()); > > and then tried calling > >         pasProject.getProjectFrame().setVisible(true); >         pasProject.getProjectFrame().getContentPane().setVisible(true); > > Then when I click on the preview button and this code above runs, a > new window opens up that is meant to display the project but nothing > shows up in the window.
