Hi all,
I'm developing an Eclipse graphical form editor (an XML file) with GEF.=20
I think I set the right properties of the GraphicalViewer but I don't =
see the grid.
How can I set the step of my grid?
Thank in advance,
Paolo.
Here's some code snippets...
protected void createGraphicalViewer(Composite parent) {
=20
IEditorSite editorSite =3D getEditorSite();
GraphicalViewer viewer =3D new =
GraphicalViewerCreator(editorSite).createViewer(parent);
GraphicalViewerKeyHandler handler=3Dnew =
GraphicalViewerKeyHandler(viewer);
KeyHandler parentKeyHandler =3D =
handler.setParent(getCommonKeyHandler());
viewer.setKeyHandler(parentKeyHandler);
getEditDomain().addViewer(viewer);
this.graphicalViewer=3Dviewer;
getSite().setSelectionProvider(viewer);
viewer.setContents(form);
loadProperties();
}
protected void loadProperties() {
=20
// Snap to Geometry property
=
getGraphicalViewer().setProperty(SnapToGeometry.PROPERTY_SNA P_ENABLED,Boo=
lean.TRUE);
=20
// Grid properties
=
getGraphicalViewer().setProperty(SnapToGrid.PROPERTY_GRID_EN ABLED,Boolean=
..TRUE);
=20
// We keep grid visibility and enablement in sync
=
getGraphicalViewer().setProperty(SnapToGrid.PROPERTY_GRID_VI SIBLE,Boolean=
..TRUE);
=20
}

Thanks a lot Andreas,
I set not opaque the topmost figure of my hierarchy and I saw the grid.
But the figure didn't catch the move request of its children (it did
before), so I subclass the RootEditPart of my viewer changing the order of
layers creation like this:
public class DeServerRootEditPart extends FreeformGraphicalRootEditPart {
protected GridLayer createGridLayer() {
return new DeServerGridLayer();
}
protected void createLayers(LayeredPane layeredPane) {
layeredPane.add(getPrintableLayers(), PRINTABLE_LAYERS);
layeredPane.add(new FreeformLayer(), HANDLE_LAYER);
layeredPane.add(new FreeformLayer(), FEEDBACK_LAYER);
layeredPane.add(new GuideLayer(), GUIDE_LAYER);
layeredPane.add(createGridLayer(), GRID_LAYER);
}
}
Now it goes but, in my opinion, the best way to do it is to display the grid
in the topmost figure of my hierarchy.
What do you think about it?
Thanks in advance,
Paolo.
