[directfb-users] Problem with DWET_BUTTONDOWN in df_window

[Tu Duong Manh]

Hi, 

i've modified the code of df_window, after every outcommenting, i've compiled 
and tried to start the program again.
The only important change is that i use for every window an own ID. My problem 
is, that DWET_BUTTONDOWN doesn't
work.  "evt.window_id == id1" is working, i've controlled it. 
Thanks for reading and help.

int main( int argc, char *argv[] )
