I've built a GEF-based editor with an EMF-based model to support it.
The editor is being displayed inside an RCP application perspective.
When I launch the editor, I can see the palette, but there is nothing
displayed on my editor canvas. I'm expecting to see two node figures,
because I've hacked my editor input to contain a sample model.
I've compared my code to the Shapes example, and it seems that I have
all the right hooks in place. Below are the methods that I've been
focusing on as part of my troubleshooting. Can anyone point me to other
places that I should be checking for missing pieces?
From ScenarioEditor.java:
protected void setInput(IEditorInput input)
{
super.setInput(input);
ScenarioEditorInput scenarioInput =
((ScenarioEditorInput) input);
// scenario is set to a sample model instance
scenario = scenarioInput.getScenario();
setPartName(scenarioInput.getName());
}
public void createPartControl(Composite parent)
{
SashForm sashForm = new SashForm(parent, SWT.HORIZONTAL);
sashForm.setBackground(parent.getBackground());
paletteViewer = createPaletteViewer(sashForm);
graphicalViewer = createGraphicalViewer(sashForm);
sashForm.setWeights(new int[] { 30, 70 });
}
private GraphicalViewer createGraphicalViewer(Composite parent)
{
// create graphical graphicalViewer
GraphicalViewer viewer = new ScrollingGraphicalViewer();
viewer.createControl(parent);
// configure the graphicalViewer
viewer.getControl().setBackground(ColorConstants.white);
viewer.setRootEditPart(new ScalableFreeformRootEditPart());
viewer.setEditPartFactory(getEditPartFactory());
// hook the graphicalViewer into the EditDomain
getEditDomain().addViewer(viewer);
getSite().setSelectionProvider(viewer);
// initialize the graphicalViewer with input
viewer.setContents(getContent());
return viewer;
}
From ScenarioNodeEditPart.java:
protected ScenarioNodeFigure getNodeFigure(){
return (ScenarioNodeFigure) getFigure();
}
protected void refreshVisuals() {
getNodeFigure().setName( getScenarioNode().getName() );
getNodeFigure().setLocation(
getScenarioNode().getLocation());
getNodeFigure().setSize( getScenarioNode().getSize());
}
From ScenarioNodeFigure.java:
public class ScenarioNodeFigure
extends Ellipse
implements IScenarioNodeFigure
.....
public ScenarioNodeFigure() {
// XYLayout lays out the components using the
// layout constraints as defined by each component.
layout = new XYLayout();
setLayoutManager( layout );
setBackgroundColor( ColorConstants.red );
setOpaque(true);
incomingConnectionAnchor = new EllipseAnchor(this);
outgoingConnectionAnchor = new EllipseAnchor(this);
label = new Label(" ");
add(label);
}
Thanks much.
Ben
