X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d021434cbe84b79e7d4d74404ab79f79e832677;p=profile%2Fivi%2Fweston-ivi-shell.git

downstream: ivi-shell: Implement ivi_layout_get_keyboard_focus_surface_id

This commit implements the function
ivi_layout_get_keyboard_focus_surface_id.

Note: This function is not used by wayland-ivi-extension's
ivi-controller, so it has not been tested for correct behaviour,
only that it seems correct and compiles successfully.

original patch backported to upstream Weston ivi-shell:
79e4a00 by Jonathan Maw <jonathan.maw@codethink.co.uk> on 15 of Aug 2014
