[dsdp-tm-dev] RE: StructuredViewer.handleLabelProviderChanged(LabelProviderChangedEvent event)
|
Hi Dave,
my colleague Markus Schorn, CDT committer and Eclipse
wizard, said
that he knew about the performance issues related to that
method, but
had not heard about the workaround you suggest (overriding
the method
to do nothing).
He
thinks that in some situations (depending on viewer type), that
might
make
sense.
Cheers,

I haven't. I'm going to ask Uwe, he's been working in that
area.

StructuredViewer.handleLabelProviderChanged(LabelProviderChangedEvent
event)
Hi
Martin,
I'm
seeing a problem with eclipse calling this fairly regularly when we have a lot
of items in our trees and tables (i.e. over 10,000 items). I've found
that we can resolve performance issues by overriding this method to do
nothing. What I'm wondering is if this is an issue you've heard about.
Do you know of any issues with this one?
Thanks,
