[zest] Network with pre-defined coordinates [message #247595] Wed, 04 March 2009 15:12 Go to next message

Hi,

is it possible to position nodes with Zest based on pre-defined
coordinates?

I have objects which represents physical locations and which have a name,
a longitude and a latitude. Can I place these locations via zest on their
positions?

If yes, can you point me to a small example on how to do this?

Best regards, Lars

Update:

I see that I can set the location via:

new GraphNode(g, SWT.NONE, "Test").setLocation(10,10);

Which layout manager would keep the position?

Unfortunately I cannot find any information on zest in

Best regards, Lars

Hi,

after removing the automatic layout manager I can control the points
there the nodes are placed. My question is therefore solved.

Best regards, Lars

Thanks Lars,

note, a user can likely still drag a node. Is this a problem for you?

cheers,

Hi Ian,

Thank you for the answer. No dragging a node is actually I very nice
feature.

Best regards, Lars
