[jbosstools-dev] VPE editor

[Snjezana Peco]

Hi,

I have two suggestions for improving performance in the VPE editor:

- lazy Visual Editor update
The Visual editor is updated on every keystroke. I propose to postpone 
the update for some time. This means - if a user enters a few keys 
quickly, the Visual editor will be updated only once. There is the 
org.eclipse.wst.sse.ui.sourcevalidation extenison point within the 
Webtools project that can be used for adding this feature. It is also 
possible to implement this feature using the code I added when fixing 
http://jira.jboss.com/jira/browse/JBIDE-1479 (we could use 400 ms during 
editing; this is the default value for the sourcevalidation extenison 
point).

- adding the Link (Synchronize) action to the Visual editor next to the 
Preferences, Refresh, Page Design Options actions.
This action would be a check box similar to the "Link with editor" in 
the Package Explorer view. It would be checked/enabled by default. In 
that case, the VPE would behave as it does now. If the user disables the 
action, the VPE wouldn't be updated (VpeController.notifyChanged() 
wouldn't be called). This would be very useful when editing large JSP 
files. The user could always call Refresh (or check Link) to show the 
visual part of the editor.

These features are easy to implement and don't require a lot of changes 
in the code.
