How to zoom with zest?

Question

I use RCP and ZEST to create a graph visualization application. My question is: is it possible to scale the graph drawn on ZEST (any ZEST or RCP api or plugin)?

Thanks in advance -rajit

Answer 1

I looked at the ZestZoomContributionViewItem and it seems to have posted a drop-down list with an indication of "page width" and 200% of the zoom options. I wanted to be able to use the mouse wheel to increase and decrease my graph.

The following code will close the zoom level to 500% on your Zest graph and give you fine grain control (it is a bit outdated, since these are internal eclipse classes.)

Graph myGraph = new Graph(parent, SWT.NONE);
ZoomManager zoomManager = new ZoomManager(
    graph.getRootLayer(), 
    graph.getViewport() );
zoomManager.setZoomAsText("500%");
