ActionUpdateThreadAware
that implicitly state the deprecated and costly ActionUpdateThread.OLD_EDT
mode.
When an action or an action group defines its own update
method, IntelliJ Platform tries to mimic
the old synchronous way of calling update
and getChildren
methods in the UI thread and
supply it with all the data in AnActionEvent.dataContext
.
To do that, it caches all the possible data on a background thread beforehand even if it is not needed.
Provide one of the two new modes ActionUpdateThread.EDT
or ActionUpdateThread.BGT
by overriding the getActionUpdateThread
method.
See ActionUpdateThread
documentation for more information.
