NAME

       minput_filter - Filter an input key.

SYNOPSIS

       int minput_filter (MInputContext * ic, MSymbol key, void * arg)

DESCRIPTION

       Filter an input key. The minput_filter() function filters input key key according to input
       context ic, and calls callback functions corresponding to Minput_preedit_draw,
       Minput_status_draw, and Minput_candidates_draw if the preedit text, the status, and the
       current candidate are changed respectively.

       To make the input method commit the current preedit text (if any) and shift to the initial
       state, call this function with Mnil as key.

       To inform the input method about the focus-out event, call this function with
       Minput_focus_out as key.

       To inform the input method about the focus-in event, call this function with
       Minput_focus_in as key.

       To inform the input method about the focus-move event (i.e. input spot change within the
       same input context), call this function with Minput_focus_move as key.

RETURN VALUE

           If key is filtered out, this function returns 1. In that case, the caller should
           discard the key. Otherwise, it returns 0, and the caller should handle the key, for
           instance, by calling the function minput_lookup() with the same key.
