    Hi folks, I just wrote a basic report viewer and I would like to open file from my main application with it.
    This viewer has a QMdiArea, hence I would it to have a correct behavior.

    • When closed and called from main app: run the application and open the report
    • When already running and called: do not start a new instance and open a new tab instead.

    Do you guys have any example I could look at to handle this?
    Thanks a lot

      There is a "Qt Solution":http://doc.qt.nokia.com/solutions/4/qtsingleapplication/index.html for that.

      I guess the "code":https://qt.gitorious.org/qt-solutions can still be found in Gitorious.

        Thanks for the hint.
        Some of those old Qt Solutions have been merged with Qt. Are you sure this one has not?

          Quite sure this one has not. Or do you see a QSingleApplication class in your QAssistant?

            AFAIK it was not merged. But it's pretty easy to use and works like a charm... :-)
