Hi all,
I've some problems in rendering a graph with an huge amount of edges and
nodes. When I start the drawing of a graph of 30000 edges and nodes, even
using correctly rcp thread support (i.e. Jobs classes or asyncexec, syncexec
Display methods), the screen freezes for 8 sec and then the graph is
displayed. By means of Tptp profiling tools I've noticed that the recursive
method addChild of AbstractEditPart notifies the graph element addition to
every children recursively, and it takes about 5 sec to do that starting
from root editpart. Is there any solution to prevent screen freezing,
considering that addChild event notification is a time consuming task,
embedded inside a class that does UI operations (AbstractEditPart)? Any
suggestions and help is welcome :-)
Thank you very much in advance,
