filtering comboviewer on linux and mac [message #719203]

This is a pretty basic question but I could not find anything about it on the forum so I figured that I would ask. I have a comboviewer for which I implemented a auto-complete capability by adding a viewerfilter and a keylistener to it. What I mean by auto-complete is that as the user types in the combo, I want the choices in the combo's pull down to filter down to just the set that contains the string that I have typed. Using a ViewerFilter and KeyListener combination worked great on Windows to get this effect but when I tested the same solution on Linux and Mac the filtering seemed to be ignored.

My question is, should have using a viewerfilter and keylistener worked on these platforms? I just want to know whether I should be looking for a bug in my implementation or whether changing the combo choices once the combo is expanded is just not supported on these platforms and I need to consider using the AutoCompleteField or some other solution instead.

Thanks.

Hi Mark,

Assuming you mean an org.eclipse.jface.viewers.ComboViewer, you should
ask this on the eclipse.platform.jface newsgroup, since jface is not
part of swt.

Not sure if it's helpful or not, but for an example of doing something
somewhat similar (content assist) at the swt level see
http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet320.java
..

Hi Grant,

Yes, I did. I apologize for sending to the wrong group. I will try to be more careful in the future.

Thanks for forwarding me to the snippet. That does look helpful.
