How to determine the trigger for Content Assist! [message #325504]

Can anyone tell me if it is possible to determine what triggered a content
assist?
I have my completion processor and most things work fine but I have a
problem where I need
to obtain the char (or sequence of chars) that triggered the Content Assist.

Basically my problem is that in my editor the user enters '(' like the
Content Assist for
Java I want to display content assist - this works fine and when the user
enters a ')' I want to
terminate or not show any more proposals - I am implementing this by looking
for a ')' in the Document
and if I find one just return empty proposals.

BUT: If the user hits ctrl+space then I want to display the proposals - this
is where I am having my
problem! At the moment, nothing will happen if there is already a ')' in the
Document so I was hoping to look for
the trigger that invoked Content Assist and if it was Ctrl+Space then I
would go ahead and get proposals.

Does this make sense??

Since 3.4 the content assist event tells you whether auto-activation
happened or not. If yes, you could get the trigger char from the viewer.
