Only one Q_EXPORT_PLUGIN macro per library is allowed. But you can put multiple custom widgets into a single plugin, from http://doc.qt.nokia.com/4.7-snapshot/qtdesigner-components.html#creating-custom-widget-plugins : "If you want to include several custom widget plugins in the same library, you must in addition subclass QDesignerCustomWidgetCollectionInterface" An example how that works would e.g. be the custom widget collection we have for Qt Creator development: https://qt.gitorious.org/qt-creator/qt-creator/trees/master/src/tools/qtcreatorwidgets Br, Eike -- Eike Ziller Principal Software Engineer Nokia, Qt Development Frameworks Nokia gate5 GmbH Firmensitz: Invalidenstr. 117, 10115 Berlin, Germany Registergericht: Amtsgericht Charlottenburg, Berlin: HRB 106443 B Umsatzsteueridentifikationsnummer: DE 812 845 193 Geschäftsführer: Dr. Michael Halbherr, Karim Tähtivuori _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
