propagate preferences to a plugin editor [message #306460]

Hello,

I would like to know how to propagate changes in color options to
editors that are already opened. I have created a
IPropertyChangeListener and asociated it with my preferenceStore. But
once I see that something has changed, how can I tell to the editor to
scan again the text in order to update the colors?

thanks

That's totally editor dependent ... for example, in source viewer based
editors (like the java editor) your invalidate the text presentation
which forces the editor to re-run the partitioning/reconciler code.

It's mentioned in the news groups, you should be able to find them.

Note that this is not needed if your editor extends AbstractTextEditor
or one of its subclasses. There is already a hook
(handlePreferenceStoreChanged(PropertyChangeEvent)) which is called when
preferences change.
