Hi.
I am desperately trying to make snap to grid work in containers, and
containers in these containers, and so on...
My intention is to make a document designer where you can drag and drop
texts, images, lines, boxes etc, etc,
from the palette. I have some properties on the document saying what size
the top, bottom, left, and right margins
should be. My bottom figure in the editor is only used as a background, gray
in color. The first child figure of the
bottom figure is representing the blank sheet (A4 for now), and I call it
the 'sheetFigure'. This figure has a content
figure with the size of the 'sheetFigure' figure minus the margins. It is in
this figure I want to have my first grid !!
If I put a box in that figure I want that box to have its own grid, and so
on.
I have turned the logic example inside-out, and I still don't understand how
to put the grid into child containers of
the bottom FreeformGraphicalRootEditPart which is the root edit part of my
ScrollingGraphicalViewer. The logic
example puts the grid in the bottom figure belonging to the
LogicDiagramEditPart. That class implements the getAdapter
method from the org.eclipse.core.runtime.IAdaptable interface. I have done
the same in my 'SheetEditPart', but I don't
even get a call to that method. Now I feel like I have run out of options.
Thanks in advance!
/Stefan

LayeredPane).
2. Make them using local coordinates (override useLocalCoordinates to return
true).
3. Add two layers - one for grid and one for content:
public ContainerFigure() {
add(new GridLayer(), LayerConstants.GRID_LAYER);
add(new MainLayer(), LayerConstants.PRIMARY_LAYER);
}
And that should work - if I hadn't forgotten anything...
Best regards,
Eugene

I've finally had a break through. I missed implementing the 'LayerConstants'
interface in the edit parts
that are supposed to have a grid. It works now !
Now I have another problem. I can't get the grid to become visible...??!! I
set the appropriate properties
in the viewer according to the logic example,
getGraphicalViewer().setProperty(SnapToGrid.PROPERTY_GRID_VI SIBLE,
new Boolean(true));
getGraphicalViewer().setProperty(SnapToGrid.PROPERTY_GRID_EN ABLED,
new Boolean(true));
and when I debug my code I can see that those properties are actually set to
true. Still , I can't see any grid. I have
also installed the 'SnapFeedbackPolicy' on the edit parts in question, and
that works just fine.
Anyone?

Thanks Eugene!!
This really helped me. If you could bare another question from me, I'd be
more than greatful.
I use a pretty fine grid, 2x2 pixels, and when I add edit parts to that
container, the grid is drawn
above them. I have laborated with the setOpaque() method both on the edit
part and on the grid layer
itself but without any success, and it seems as if I have run out of options
again.
Thanks in advance.

Check that the grid layer is below the content layer (see my example).
I forgot to mention that you should override the getContentPane method in
your container edit part like:
public IFigure getContentPane() {
return ((LayeredPane)
getFigure()).getLayer(LayerConstants.PRIMARY_LAYER);
}

And that's exactly what I did, and it works just fine :-) !!!
Again, thank you, Eugene.
