Hi all,

I a m trying to use the Zoom capability provided by draw2d. I found some
examples in the GEF examples plugin. It works fine but i still have a
problem. In these example no ScalabledLayerdPane are used. Instead of this
a ZoomContainerFigure is created and ovveride the paintClientArea method
to take into account a zoom factor using a scaled graphic.

I tried to use instead of this the provided class ScalableLayeredPane but
using this figure i can't get anything displayed.

Does anybody used it and have you a sample program showing how to use it ??

Thanks

Manu

Hi Manu,

i found this in the LogicExample:

LogicEditor line 407:

[...]
protected void configureGraphicalViewer() {
super.configureGraphicalViewer();
ScrollingGraphicalViewer viewer =
(ScrollingGraphicalViewer)getGraphicalViewer();

ScalableFreeformRootEditPart root = new ScalableFreeformRootEditPart();

List zoomLevels = new ArrayList(3);
zoomLevels.add(ZoomManager.FIT_ALL);
zoomLevels.add(ZoomManager.FIT_WIDTH);
zoomLevels.add(ZoomManager.FIT_HEIGHT);
root.getZoomManager().setZoomLevelContributions(zoomLevels);

IAction zoomIn = new ZoomInAction(root.getZoomManager());
IAction zoomOut = new ZoomOutAction(root.getZoomManager());
getActionRegistry().registerAction(zoomIn);
getActionRegistry().registerAction(zoomOut);
getSite().getKeyBindingService().registerAction(zoomIn);
getSite().getKeyBindingService().registerAction(zoomOut);
[...]

hope this is of any help to you ;)

cheers

Oliver

Thanks Oliver,

I also founded this piece of code in the logic Example this morning and
solved my problem.

Thanks

Is your zoom combo box enabled?

Mine isn't (I've also copied from the logic Example today).

But I did succeed in getting the zoom in and zoom out toolbuttons.

I've now successfully enabled the zoom combo box.

I had to implement the ERDiagramEditor#getAdapter() method,
as defined in the IBM "Using the Graphical Editor Framework
and the Eclipse Modeling Framework", on page 146/147 (and in the
LogicEditor of the example, for that matter. But the redbook actually
_explains_ it...:-) ).

The redbook can be found at:
