Connecting QApplication event with QMainWindow instance

[xtingray]

Hi,
I found this interesting example in the Qt documentation:

#include <QApplication>
#include <QFileOpenEvent>
#include <QtDebug>

class MyApplication : public QApplication
{
public:
    MyApplication(int &argc, char **argv)
        : QApplication(argc, argv)
    {
    }

    bool event(QEvent *event)
    {
        if (event->type() == QEvent::FileOpen) {
            QFileOpenEvent *openEvent = static_cast<QFileOpenEvent *>(event);
            qDebug() << "Open file" << openEvent->file();
        }

        return QApplication::event(event);
    }
};

Now, in my case I have a QMainWindow instance that I want to connect with the QFileOpenEvent. Either MyApplication object and the QMainWindow object are defined in the main.cpp file.

What is the best way to connect those objects when MyApplication::event() method is triggered?

Thanks!

@xtingray
Did you try an EventFilter on either of those objects?

@kenchan Reading the documentation you shared with me I found an easy solution adding this line inside the event() method of MyApplication:

        QApplication::sendEvent(mainWindow, event);

Thanks!
