The current Linux egalax driver locates: drivers/input/touchscreen/egalax_ts.c (you can get it from Linux-next git)
When I disable multitouch in the egalax driver to let it work on single touch mode, the window of QT apps can be closed by clicked window "X" button at up-right region.

The single touch mode report "BTN_TOUCH" event comparing with multi-touch.
How to explain it ?
