Here's my solution for this, in case anyone's interested:
The header file:
#include <windows.h>
#include <dbt.h>
#include <QObject>
#include <QAbstractNativeEventFilter>
class DeviceEventFilter: public QObject, public QAbstractNativeEventFilter
{
Q_OBJECT
public:
DeviceEventFilter(QObject *parent);
bool nativeEventFilter(const QByteArray &eventType, void *message, long *result)
Q_DECL_OVERRIDE;
Q_SIGNALS:
void notify();
};
And the source file:
#include "eventfilter.h"
DeviceEventFilter::DeviceEventFilter(QObject *parent)
{
Q_UNUSED(parent)
}
bool DeviceEventFilter::nativeEventFilter(const QByteArray &eventType, void *message, long *result)
{
Q_UNUSED(eventType) // unneeded as long as we're only running on Windows
Q_UNUSED(result)
MSG *msg = (MSG *)(message);
if ((msg->message == WM_DEVICECHANGE)
&& (msg->wParam == DBT_DEVNODES_CHANGED))
{
emit notify();
}
return false;
}
