[maemo-developers] Word completion in Fremantle

[From: Felipe Erias Morandeira]

Hi,

take a look at set_preedit_buffer() in HildonIMContext:

https://stage.maemo.org/svn/maemo/projects/haf/trunk/hildon-input-method-framework/src/hildon-im-context.c

In a nutshell, the preedit text is set by emitting the "preedit-changed"
signal in the HildonIMContext (which extends GtkIMContext). You could
probably try to get a reference to the context and then either listen to
this signal or use gtk_im_context_get_preedit_string().

static void
set_preedit_buffer (HildonIMContext *self, const gchar* s)
{
  [...]

  if (s != NULL)
  {
    [...]

    self->show_preedit = TRUE;
    g_signal_emit_by_name(self,
                          "preedit-changed",
                          self->preedit_buffer->str);

    [...]
  }
  else
  {
    self->show_preedit = FALSE;

    if (self->preedit_buffer != NULL && self->preedit_buffer->len != 0)
    {
      g_string_truncate(self->preedit_buffer, 0);
      g_signal_emit_by_name(self,
                            "preedit-changed",
                            self->preedit_buffer->str);
    }
  }
}
