I developed some monitoring application by using GEF frameworks.
But, there are some performance problem to refresh/resize main viewer.
* my test condition likes below.
- application has several viewer. (main viewer, thumbnail viewer and table viewer)
- main viewer draw and refresh 15,000 figures (nodes and connections)
my application is real-time monitoring tools, so response time is very important to me.
but, when i resize main viewer, there are some delays resize viewers and refresh figures.
I tried to customise my application. But It's stiil slow.
I think.. performance of drawing/refreshing large size figures is a limitation of GEF frameworks.
the bottle nack is lightweight system.
(lightweight system->deferred update manager (ControlResize<------ here))
lightweight system is GEF core source. so I don't know how to do.
am I develop my custom lightweight system?
It's not easy to me. please give me some idea.
