gtkimmodule question about focus_in method.

[hector lee <hector jeanann gmail com>]

HI all,

I am working about gtk im module. I found a method called foucs_in() in
GtkImContext class, I think this method will runing when your cusor focus in an
editable widget, it works well in all application execpt firefox. when
I open firefox the
 focus_in method run frequently even in none editable widget, example
when I open
a new tab focus_in will run but there is no edit line or edit view?
what should I do to
jude the focus widget is editable?
Thank you in advance.

BR,

Hector.
