I would think the best way to do this is to have 3 editable labels with 2
separator labels as a complex figure. For instance, create a subclass of
Figure, called DateLabel (see below). I haven't tried this, so I'm not sure of
the minor details. You may want to stop the inner labels from being selected
but I'm not sure how that affects the direct edit.

import org.eclipse.draw2d.*;
import org.eclipse.draw2d.Figure;
import org.eclipse.draw2d.Label;
public class DateLabel extends Figure {
private Label monthLabel = new Label("MM"); //$NON-NLS-1$
private Label dayLabel = new Label("DD"); //$NON-NLS-1$
private Label yearLabel = new Label("YYYY"); //$NON-NLS-1$
public DateLabel() {
setLayoutManager(new FlowLayout());
add(monthLabel);
add(new Label("/")); //$NON-NLS-1$
add(dayLabel);
add(new Label("/")); //$NON-NLS-1$
add(yearLabel);
}
}

If we make a simple change in GEF (SelectEditPartTracker), Hal could use
this figure with a single editpart. The change would be to make "direct
edit" a LocationRequest. Hal could just take the Request and compare its
location to the location of the 3 labels.
However, both of these solution only work with the mouse. You would still
have to figure out how to switch between the 3 CellEditors with the
keyboard.

Point where = ((LocationRequest)request).getLocation(); //Returns the
location on the Canvas
getMonthLabel().translateToRelative(where); //You could use any of the
3 labels for this translation
if (getMonthLabel().containsPoint(where)){
performMonthDirectEdit();
} else if ...
//etc.

Hi, Randy
I support your suggestion to make "direct edit" a LocationRequest. This
allows a larger container EditPart to handle direct edit more
intelligently. The alternatively to be to create many small EditPart
like the LogicLabelEditPart.
To me, I'd like to keep the number of classes and object creations to a
minimum. As it is, I'm already starting to worrry about the number of
objects being created in a typical edit session. Just count the number
of EditPart in realatively large diagram. Add the number of edit
policies (average 2-3 per editpart) and the number really starts to
escalate.
Hope this LocationRequest thing gets implemented.
Cheers,
Edison

Thanks. Isn't it true that I need to create a LogicLabel, LogicLabelEditPart
(like in logic editor example) in order to support DirectEdit? In your
example below, I am not sure how to initialize cell editor value with the
correct label content.
Thank you.

Yeah, you're right. If you went this route, you'd have to have the DateEditPart
mirror the DateLabel's hierarchy (i.e. a DateEditPart would need 3 child
EditParts -- one for month, one for day, and one for year). I think Randy's
idea of making the direct edit request a LocationRequest is much easier.
