Commaseparated list with inline-completion with QLineEdit and QCompleter

Hello,

I'm currently developing a tagging-dialog for a media company using qt4 on their client software. The dialog has a QLineEdit where you is supposed to be able to enter a comma separated list of tags. A feature we have been looking to add to this is auto-completion of the tags.

This is the current code:

Code:

---

QCompleter *completer = new QCompleter(complist);
completer->setCaseSensitivity(Qt::CaseInsensitive);
completer->setCompletionMode(QCompleter::InlineCompletion);
ui.tagEdit->setCompleter(completer);
completer->setCompletionPrefix ( text.split(",").back().trimmed().toLower() );

It works ok for the first word, when you start writing on a empty line. But I also want it to work, as if it was a blank line, after a comma. ie. if you write "indie, roc" the last word should inline-complete to rock the sameway as if you only wrote "roc". Hope that make sens.

I have build
http://www.qt-apps.org/content/show....?content=59422

word completer from DB sqlite and grep word from text....

to insert comma separated word... replace Space and special sign by ##_## as example
and after iterate QTextDocument to replace the placeholder....

completer not like space...

Solved it. Thx :) If you want to see the result, download the Last.fm client v1.4 when it's released.

Here's a stupid simple solution. I like this one the best

This also seems to do the job for the most part. When you actually do a completion it replaces the text in the line edit so more work might be needed or special handling on the line edit side would have to be implemented

Code:

---

class QdTermCompleter(QtGui.QCompleter):
    def __init__(self, parent=None):
        QtGui.QCompleter.__init__(self, [], parent)
        self.terms = []
 
    def setTerms(self, terms):
        self.model().setStringList(terms)
 
    def splitPath(self, path):
        raw_values = str(path).split(",")
        values = [val.strip() for val in raw_values if val.strip()]
        if len(raw_values) != len(values):
            return [path]
        return [values[-1]]
