Regarding GTK Entry keys

[AshokKumar G <ashok sysprogrammer gmail com>]

Hi,
         I am new to GTK+ programming. I have created a test application
with GtkEntry on embedded system based on ARM and backend target is
DirectFB-1.2.9. I am able to enter the text into GtkEntry field. But when I
use BackSpace, Delete, Arrow Keys (left or right for navigation), no action
is taken. In my test application I have registered call back key-press-event
to verify whether event is coming or not, when I press backspace the event
is coming and I am returning FALSE from that call back function. But no
character is getting deleted on backspace/delete key press.
         But when I run my same test application on PC GTK+same version with
backend target X11, then all the actions are performing as expected.
         Could some one help me on this?

Thanks & Regards,
