How to specify trigger key for content assit in Eclipse RCP editor?

Question

There is a method getCompletionProposalAutoActivationCharacters in ContentAssistProcessor that can return characters which trigger the completion proposals. For example I can return new char[] { '.' } return new char[] { '.' } so that each time I type dot in the editor the word completion proposal shows up.

I thought that there should be a simular way to specify shortcut key stroke to trigger content assist such as Alt + / , but actually that's different.

What is the best way to do this? I personally don't want to hard code a key listener for this.

Answer 1

JDT does that. They have a command+handler+keybinding to invoke the content assist.
See org.eclipse.jdt.internal.ui.text.java.JavaContentAssistHandler for the implementation.
You can do similar one
