Scrolling diagram nodes into view [message #730694]

I would like to select a particular diagram node - respectively potentially multiple nodes - and then scroll them into the user's visible field on a best effort approach. I.e. if there is only one node or the selected nodes are conveniently close, the view is scrolled and centred on the cluster and the user indeed can see all selected nodes. Otherwise, it does something default like e.g. always scrolling to the first node.

Main question is: Does anyone know if this functionality or something similar is already existing in the GMF framework somewhere?
If not, where would be a good point to insert this or start from?

Thanks,
Thomas

Hi,

you need two things 1) Your DiragramEditor (editor) and 2) The edit part (editPart) you want to scroll to. Then do the following:

editor.getDiagramGraphicalViewer().select(editPart);
editor.getDiagramGraphicalViewer().reveal(editPart);

Hi Ralph,

Thanks for the reply. I managed to do in the following lines of code:

GraphicalViewer gv = (GraphicalViewer)editor.getAdapter(GraphicalViewer.class);
FigureCanvas figureCanvas = (FigureCanvas) gv.getControl();
figureCanvas.scrollTo(coordinatesRectangle.x,coordinatesRectangle.y);

where the editor is the DiagramEditor and the x and y are the new values the scroll should take place.

Hope this helps to somebody else also.
