How to change completion rule of QCompleter

[jungle]

After a lot of studying up on how this works, I've finally figured it out. I've implemented my own version as well, but I have a question.

My problem is that when the first letter entered into the editable combobox is actually the first letter of an entry, that entry is automatically selected. This bypasses completion of a single letter.

For example. The list is:
chicken broth
cinnamon
boneless chicken breast

I want "c" to show all of these as possible completions. However, "c" will cause the combobox to select "chicken broth" instead. I've looked, but I can't figure out how to disable this behavior. Any suggestions?

Thanks
Bill

edit: btw, hitting "c" will make the edittext read "chicken broth." And hitting backspace will remove all but the "c." Then it completes like i want it to. Obviously, I don't want to have to hit backspace every time.
