In Linux, how can I use QT to detect that the USB flash disk has been inserted and mount and umount can be automatically copied when an automatic USB flash disk is inserted, and the USB flash disk must be formatted before the replication starts.
If you want Linux to format the USB flash disk first, then load the USB flash disk. After loading the disk, copy the disk and uninstall it automatically. Solution: Use the q6. the connection is as follows: Code When a device is inserted, you can call the slotdeviceadded function. Copy code
Qdbusconnection: systembus (). Connect ("org. freedesktop. Hal ",
"/Org/freedesktop/hal/manager ",
"Org. freedesktop. Hal. Manager ",
"Deviceadded ",
This,
Slot (slotdeviceadded (qstring )));
