Hi,
I have a problem, which seems really easy but which I can´t solve.
the situation:
I have a tree-like model, a root-Element (e.g. ContentElement) with
NodeElements under it. NodeElements can contain other NodeElements as
well. Now I want to visualize it.
First I overwrote the getModelChildren()-method of the
ContentsElementEditPart like this
public List getModelChildren(){
//returns the direct child nodes of the ContentsNode
return model.getChildren();
}
the result is, that only the children of the ContentsElement will
visualized.
So I overwrote the getModelChildren()-method of the
NodeElementEditParts. The result is, that all nodes of the tree are
created, but they are visualized within the parent ElementNodes. I would
like to have them as children of the ContentElement, so I can visualize
a tree with connections and fancy decorators (based on informations
within the ElementNodes).
Not satisfied I tried something else:
I overwrote the getModelChildren-method of the ContentsElementEditPart
again and collected all child nodes recursivly into a List.
(Construction of connections and decorators is done here later, too.)
The getModelChildren-method of the ElementNodes has been removed. Now
all nodes are visualized within the figure of the ContentsElementEditPart.
So finally I reached the goal, but it seems not to be that clean.
Perhaps someone could give me a hint how it could be done more
"professional".
I did not find an example, where model elements include elements of the
same type (or I did not recognize it :-( )
Many regards
Andreas
