Hi again,
I wrote this example program, but it does not seem to work. The filter is
never hit on Windows even though I copied the qwindow.dll to the platforms
directory of my build tree. Do you know this would not work on Windows? The
filter is hit on Mac and Linux. Thanks.
Kind regards,
László
#include <QAbstractNativeEventFilter>
#include <QApplication>
#include <iostream>
class MyMSGEventFilter : public QAbstractNativeEventFilter
{
public:
bool nativeEventFilter(const QByteArray &eventType, [[maybe_unused]]
void *message, long *) override
{
std::cout << eventType.toStdString() << std::endl;
#ifdef Q_OS_WIN
if (eventType == "windows_generic_MSG") {
MSG *msg = static_cast<MSG *>(message);
} else if (eventType == "windows_dispatcher_MSG") {
MSG *msg = static_cast<MSG *>(message);
}
#endif
return false;
}
};
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyMSGEventFilter filterObject;
app.installNativeEventFilter(&filterObject);
return app.exec();
}
