Hi,

In java, when the list of proposals is displayed, if I typed in the '('
character, the current proposal (the highlighted one) from the list of
proposal is automatically chosen, and context info popup is shown. How
is that done in the Java editor? Thanks.

This is done by the content assistant framework: it asks the selected
proposal for its trigger characters and if they match the entered
character it will be inserted and context assist started.

Yeah, after debugging through the JDT's editor...It turns out that one's
completion proposal must implement the interface
ICompletionProposalExtension in order for Eclipse ask for the trigger
chars from the completion object.
