Maximize Graph Width to View Width [message #843659]

Hello!

i try to write a view which contains a graph (which should fit to 100% of width of the view -> if the view gets increased the graph shall increase its size too.

i tried to create an EditPart which uses this code

	@Override
	protected IFigure createFigure() {
		Figure figure = new FreeformLayer();
		figure.setBorder(new MarginBorder(3));
		figure.setLayoutManager(Utils.getLayout(1));
		contentPane = new Panel();
		figure.add(contentPane, new GridData(GridData.FILL_BOTH));
		contentPane.setLayoutManager(new XYLayout());
		return figure;
	}

	public IFigure getContentPane() {
		return contentPane;
	}

this does not resize as i expected it to do.

its also not possible to gain the width of the control itself (from the figure)

super.getParent().getViewer().getControl().getBounds();

UPDATE: i also tried:

	public Dimension getViewSize() {
		ScrollingGraphicalViewer viewer = (ScrollingGraphicalViewer) super.getParent().getViewer();
		return ((FigureCanvas)viewer.getControl()).getViewport().getSize();
	}

so... how can i get those dimensions i need?
thanks in advance!

If you put the graphical viewer into a ViewPart, and set the FillLayout on the view's root composite (the graphical viewer's control parent). Then the graphical viewer itself should be automatically resized upon view resizing.

Thats not The problem
It's to scale the graph inside to fill the full view

Then you can use the zoom manager if your root edit part is either instance of the ScalableRootEditPart or the ScalableFreeformRootEditPart:

ZoomManager zoomManager = (ZoomManager) EditPartViewer.getProperty(ZoomManager.class.toString());
zoomManager.setZoomAsText(ZoomManager.FIT_ALL);
