More completitions per lineedit?

[jiveaxe]

I'm asking if it is possible to call multiple times a completer on a QLineEdit after inserting a separator character. Let me explain with an example:

Let's say we have


QStringList wordList;
wordList << "alpha" << "omega" << "omicron" << "zeta";

QLineEdit *lineEdit = new QLineEdit(this);

QCompleter *completer = new QCompleter(wordList, this);
completer->setCaseSensitivity(Qt::CaseInsensitive);
lineEdit->setCompleter(completer);

typing on the lineedit pops the completer; I choose one of the entry in the list, then type a delimeter character like ',' and start typing again triggering again the completer; here a mockup

I dunno if a similar implementation was already adopted by any app; if so, please tell me which one.

Very thanks

You need a hierarchical model containing all permutations of the words and reimplement splitPath() using the separator of your choice.

Since my list will contain ~4K elements, do you think that the method you suggest is still applicable?

Thanks

Yes, it's applicable. Of course you have to generate the combinations on the fly instead of statically inserting all elements into the model.
