Qt COM Objects and QApplication



  • I have a simple question. If I have several Qt Com Objects does each Qt COM object (created using QAxBindable & QAxAggregated) has its own QApplication instance or somehow they all relate to the same QApp object?
    If it is the later how can that be?


  • Qt Champions 2017

    There will be one QApplication for each Application. Even for COM components it will be same as Qt provides the container in the form QaxObject and QaxWidget. Every object looking for QApplcation access the same the qApp variable exposed to every object.
