Custom editor content assist tab behavior [message #779947]

Hello, I've been dinking around with making a custom editor for a few days, primarily going off the Java Editor example and am trying to put the finishing touches on.

One of my completion processors is based on Templates, and I can't figure out how to enable tab highlighting after entry.

For example, typing method =>
[public] [void] [methodName]([paramlist]) {
//TODO implement
[functionbody]
}

where it highlights public first and then on a tab highlights the next phrase in brackets, and so on.

I managed to find the Java Editor that Eclipse uses but when I looked at that it didn't even seem to be using the same org.eclipse.jface.text.contentassist constructs.

I overrode an implementation of ICompletionProposal.getSelection and can use that to select the first word I want, but don't know where to go from there.

Any suggestions?

Are you talking about the highlighting once the template/code is
inserted? If so, what you want to look at is the linked mode UI. Take a
closer look at
org.eclipse.jdt.internal.ui.text.template.contentassist.TemplateProposal.apply(ITextViewer,
char, int, int).
