Hi, EFL developers.
ATM, edje entry doesn't display the style of preedit string such as
underline, reverse, and Highlight.
It's because XIM module doesn't provide the style attribute.
This patch is made for providing the style attibute information to entry or
other editable widget.
edje_test.patch.txt is for verifying this patch. (This patch is written by
Woohyun and Woohyun will commit edje_entry patch with edc patch)
Would you please review ecore_imf_xim_attribute.patch.txt file?
Thanks.
