It looks like ScalableFreeformRootEditPart has GridLayer() in it but it
doesn't display.

How to make it work? Do I need to override some methods?

Take a look at how ToggleGridAction does it.

Is it enought to initiate class in order to make Grid visible?

What should be the moment to do that?

Greg, as Martijn suggested, look at ToggleGridAction to see how to turn the
grid on and off. You can see how the logic example uses this. You can set
the grid enablement properties on the viewer in your editor's
configureGraphicalViewer() method. If the grid's still not visible you
probably have an opaque layer (such as your primary layer) above the grid
layer that's preventing it from being seen. If that is the case, snapping
to grid should still work (although the grid itself won't be visible). Just
ensure that you're not invoking setOpaque(true) on any of the layers.

I'm adding these two lines to my Editor:

ToggleGridAction grid = new ToggleGridAction(graphicalViewer);
getActionRegistry().registerAction(grid);

and I'm not setting any of layers by myself. I'm using
ScalableFreeformRootEditPart which seems to be seting Layers by itself.

Grid is still not visible. Do I need to use this registered action
somewhere in order to turn the GRID on??

Gregory

Ps. Sorry that my questions are so LAME :)

The action is to turn the grid on or off. Creating that action doesn't turn
the grid on. You need to set the grid properties for that. The logic
editor does that in its loadProperties() method. The ToggleGridAction
toggles those properties in its run method. So you should look at either
one of those to see what properties you need to set.

Well that was good enought :)

Thank You Pratik.

It's shame there's no book that will say in order to provide "this" with
GEF do "that" :)

Java DOC doesn't explain a lot of simple actions in order to provide
simple functionality.
