Hi,

I want to use the "ToggleSnapToGeometryAction" in my ActionBarContributor
...but the ToggleSnapToGeometryAction needs a 'GraphicalViewer' in the constructor.

I don't know how to retrieve this in my ActionBarContributor.

Is there a common way to enabel/disable the Grid in my GEF Editor?

Hi Andreas!

I did it this way!
Create the Action in your editor class in the configureGraphicalViewer
method:

protected void configureGraphicalViewer()
{
super.configureGraphicalViewer();
IAction action = new ToggleSnapToGeometryAction(getGraphicalViewer());
getActionRegistry.registerAction(action);
getSelectionActions().add(action.getId());
}

Create a ToggleSnapToGeometryRetargetAction:

public class ToggleSnapToGeometryRetargetAction extends RetargetAction
{
public ToggleSnapToGeometryRetargetAction()
{
super(null, null, IAction.AS_CHECK_BOX);
setText("Snap to geometry");
setId(GEFActionConstants.TOGGLE_SNAP_TO_GEOMETRY);
setToolTipText("Snap to geometry");
setActionDefinitionId(GEFActionConstants.TOGGLE_SNAP_TO_GEOM ETRY);
}
}

In your ActionBarContributor class:

protected void buildActions()
{
addRetargetAction(new SnapToGeometryRetargetAction());
}

public void contributeToMenu(IMenuManager menubar)
{
super.contributeToMenu(menubar);
MenuManager myMenu = new MenuManager("My Menu");
myMenu.add(getAction(GEFActionConstants.TOGGLE_SNAP_TO_GEOME TRY));
menubar.insertAfter(IWorkbenchActionConstants.M_WINDOW, myMenu);
}

If you use a MultiPageEditor things are a bit more complicate.
Hope this helps.

Hi,

thanks a lot!!!

I have changed the RetargetAction constructor to:

public class ToggleSnapToGeometryRetargetAction extends RetargetAction
{
public ToggleSnapToGeometryRetargetAction()
{
super(GEFActionConstants.TOGGLE_SNAP_TO_GEOMETRY,
GEFMessages.ToggleSnapToGeometry_Label, IAction.AS_CHECK_BOX);
setToolTipText(GEFMessages.ToggleSnapToGeometry_Label);
setImageDescriptor(JacobDesigner.getImageDescriptor("alignGeometry.png "));
}
}

and it works fine. I have add an image for the toolbar too.

Thanks!!

Andreas
