Hi,
I have an application in both RAP and RCP that its views are updated from background threads, this is accomplished with the display.syncExec(...) mechanism and this work fine for both of them.

But in RAP the performance drops, when a view is sort of complex or with several widgets, it could take 6 seconds or more to the application to render the changes to the view. While in RCP this doesn't even takes a second.

Does any body knows how to optimize this?

Hi Jesus,
it depends on the widgets in the view. Do you have any "fat" tables or
trees in this view? Are they virtual? How many items do you have in them?
Best,
Ivan

Well, the view has around 70 single widgets (texts, combos, ..), and contains 9 tables but they are not fat or virtual but they all have cell editors.
The widgets are distributed in the view by TabItems.

After doing some tests I found that the widgets that are creating the delay are the tables with the table editors. So any ideas to improve this?

Hi Jesus,
as I asked you previously, how many items do you have in the Table? How
many columns? Is the table virtual? If not make it virtual.
Best,
Ivan
