Hi all,

i am doing with a program to parser the xml file, which include the
geographic information of the maps, and try to show the nodes and ways
with diagram. i used RCP and Draw2D in eclipse. unforturnaly there are not
many articles about the development with Draw2D. now i have a problem:
i drawed all the nodes and ways of the maps with draw2D sucessfuly in a
RCP viewer, how can i scale the figures? like zooming the map.
if i want to scale the figures, must i use the ScalableFreeformLayeredPane
in draw2D? are there some example source code about scaling?
by the way, where can i find some good texts about the using with draw2D,
like scale, drag and drop the figures.

thanks

Juewei

Download example codes from Eclipse cvs, full path is
:pserver:anonymous@dev.eclipse.org :/cvsroot/tools/org.eclipse.gef/examples/org.eclipse.draw2d. examples.

There's a demo named ZoomExample.
