Hi,
I have a model which contains a hierarchy structure of nodes. Everything
works fine if I create
all the node objects in the method
AbstractEditorPage#createGraphicalViewer() and the GEF
EditPartFactory#createEditorPart() will eventually be invoked to create the
edit part for all the
nodes.
But the diagram is so complex, I would like to only create the first level
of nodes and let the
user click on a specific node and expand it to show all the children nodes.
In this case, I do
not create all the nodes in the AbstractEditorPage#createGraphicalViewer(),
and only add
those children nodes to the diagram when the parent node is expanded.
I only call GraphicalViewer.setContents(diagram) in
AbstractEditorPage#createGraphicalViewer()
when the editor page is first loaded. How do I added those new children
nodes to my diagram
and invoke the EditPartFactory#createEditorPart() to create the
editparts/figures for those new
nodes? By the way, I am not using any palette at all.
Thanks
slam

getModelChildren() should return an empty list when the node is collapsed,
and the actual children when the node is expanded. You'll have to invoke
refreshChildren() when a node is collapsed/expanded.
