I am trying to set grid of Graphical Viewer to look like dot style.
something like this:

.. . . . . . .
.. . . . . . .
The goal is when figures are dropped in the view and got connected with
relation, user can simply select the figures and relation and click on
Align button. The result will be that all selected figures are Aligned
to this dots.
Currently my viewer properties look like this:
viewer.setProperty(SnapToGrid.PROPERTY_GRID_VISIBLE,
new Boolean(true));
viewer.setProperty(SnapToGrid.PROPERTY_GRID_ENABLED,
new Boolean(true));
viewer.setProperty(SnapToGrid.PROPERTY_GRID_SPACING, new Dimension (22,22));
.... Any ideas how I can do that?
I hope I was clear in my question…
Thanks

Override GridLayer#paintGrid(Graphics g) to paint the grid differently.
Then specify your custom layer in createGridLayer() of your RootEditPart.

You also need to be sure that you answer a SnapToHelper class in
getAdapter on your diagram edit part.
After that, snapping should "just work" when new parts are created. The
users shouldn't have to click any manual alignment action.
