Orderless completion in QCompleter

[dheerajshenoy]

Hi. I would like to implement orderless completion for my QCompleter. Let's say I have a QStringList with items item-one, item-two, item-three. If I type three item (notice the space in between) the popup should show item-three. I did implement QSortFilterProxy to split all the items in the QStringList by hyphen. But even after playing around with splitPath method of QCompleter I cannot get it to work.

What you describe does not sound like "orderless", but more like "match any substring".

What if you set filterMode to Qt::MatchContains?!
This will match anything that contains "item" and "three", so you will probably end up with your desired result.

It works for the most part. The problem is that when I start typing the word and press space, the completion popup hides and is not shown.

I think this is because the completer treats it as new match/word then.
Can't tell how to change this (or how to match a result that contains multiple, by whitespace separated, words)

Maybe looking into the file path handling helps:
The input is separated by slash or backslash and split into the single layers of the tree
