[Qt-interest] QMessageBox auto close...

[OSProg]

Hi,

In the winEvent() I catch DBT_DEVICEARRIVAL and DBT_ROMOVECOMPLETE when my USB device is pluged or unpluged.
I'd like to pop-up a QMessageBox when the USB device is removed and to close the box when it is connected again.
>From the winEvent I'm calling a slot from my communication class where the QMessageBox is created and I connect its close slot to a signal from DBT_ROMOVECOMPLETE. It works fine ... almost. The problem is that when the message appears, the DBT_ROMOVECOMPLETE event is received about a minute after the USB device is connected. When I comment out the QMessageBox creation code, this message is received after 2 seconds.
Why is this delay? How can I solve that?

Regards,
Nikolay
