This function is discussed here: https://developer.tizen.org/development/guides/native-application/user-interface/efl/hardware-input-handling/grabbing-hardware-key-events

In this page, it says that this function is supported since wearable 2.3.1 (I’m on wearable 2.3.2, so that’s the only thing I’m interested at).

Also here: https://developer.tizen.org/development/api-references/native-application?redirect=https://developer.tizen.org/dev-guide/3.0.0/org.tizen.native.wearable.apireference/group__EFL__EXTENSION__HARDWARE__KEYEVENT__GROUP.html

This says that it is supported since Tizen 3.0. However in my Tizen Studio’s copy of the same Doxygen doc, it says it is being supported since Tizen 2.4.

I did “grep -RF keygrab” on my platform’s rootstraps. It returned nothing.

So I assume it is not supported, since this function is not declared in any header files or in any shared libraries. So, is there any other function I can use to achieve the same function? I need to hook the “Back” button without getting my app to quit.

Thank you.
