    [quote author="Buggy" date="1372753860"]Based on my own experience I am kind of skeptical whenever those macros are involved. Have you tried to re-run qmake (Build - run qmake)? For me, this fixed an error I had been chasing for over an hour...[/quote]

    sure I did.
    I'm asking about the principle not fixing a problem.

      I'm still stick to this issue and couldn't find any way to fix it. I need metadata to be able to read plugin information before loading it which metadata offers it.

      P.S. I'm using Qt 5.1

        Hi,

        Did you dump the content of pluginLoader.metaData() ?

        I just tried with a simple plugin and got the value of name using:
        @pluginLoader.metaData().value("MetaData").toObject().value("name").toString();@

        Also don't forget to "touch" the plugin header file before rebuilding to take the json file modifications in account.

          As AGalst suggested, you forget the key "MetaData" if you want to get access the json file contents passed in the Q_PLUGIN_METADATA. Other information such as IID can be access through the key "IID" etc.

              You're welcome !

              From the ones I searched through, no, this call for an update to the documentation

                Usually I create wiki page for missing docs but because I haven't the suitable knowledge about Qt Plugins, May you please create a wiki page.

                  Correction to the doc would have a wider impact. Can you point me to your wiki entries so I can see what would be a good addition to the official documentation ?

                    I didn't write any entries I just suggested to add them by you.

                          Definately much appreciated. I was trying to use the new metadata interface for the same reasons, and found the same lack of details in the docs. I have my own implementation working properly now (thanks to this thread), but it would be nice to have some references in the docs about this metadata and json structure.
