Drill down diagrams [message #208561]

Hello

I am looking to implement a drill-down editor where the figure on one
diagram represents a diagram at a lower level. When a drill-down control on
the figure is clicked, I want the current diagram to be replaced with the
diagram for the next level down.

I am very (very) new to GEF, are there any examples that illustrate this
functionality

Many thanks

Mike

The simplest way would be to create an edit policy that responds to the
RequestConstants.REQ_OPEN request and opens another GEF editor. This
request is sent when double-clicking on a target.

@see SelectEditPartTracker#performOpen (sends the request).

Another way: (plug for GMF :) ) would be to take a look at the animated zoom
support in GMF and when responding to the request, zoom into the figure and
dynamically display the children depending on the zoom-level.

@see org.eclipse.gmf.runtime.gef.ui.internal.editparts.Animatable ZoomManager

Thanks Steve

I like the multiple editor option. The zoom sounds very powerful, probably a
bit to sophisticated for this first project.

Cheers

There is a simpler way to show the objects based on which one is
double-clicked on and that is to override the what GetModelChildren of the
content edit returns. You could have a policy as suggested earlier that
manipulates certain model objects to only show what is required.
