Event Translation Customization from DirectFB to Gtk+

["Sharma Nitin-A21652" <nitinsharma motorola com>]

Hi All,

 

I have Gtk+ on top of DirectFB setup for an arm device.

The specific device I am using does not have a mouse.

The keyboard it supports, has only a limited set of keys.

 

I want to dynamically map the custom key symbols ( that I am generating from my limited keypad ) to

GDK_Up and GDK_Down

or

GDK_TAB.

The purpose of this mapping is to use the in-build functionality of Gtk+ for jumping between the widgets or use widget default behavior.

I believe this will make application development easier. 

 

For that I have added a map  in gdk_directfb_translate_key_event to provide the translation based on the application context.

The fields I am modifying are

+++++++++++++++++++++++++++++++

event->hardware_keycode

event->keyval

event->string

 event->length

+++++++++++++++++++++++++++++++

By this modification, I am trying create the GDK event as that, which would have got created for keyboard up_key.

 

I am receiving the event in the application with the same details as if up_key on keyboard is pressed. But the default behavior of the keyboard does not take place on the widget under focus.

 

Has anyone experienced a similar issue while porting Gtk to their devices?

 

Thanks and regards,

Nitin
