I didn't mention this in my last e-mail, but you'll also need to setup a
signal handler for the GtkIMContext object's "commit" signal.
I have it (the 'commit' signal) already connected and also its callback defined as it is in your post at http://maemo.org/pipermail/maemo-developers/2006-January/002337.html - cool !!! ... But problem begins after creating the IM_Context object and associating it with the GdkWindow of my GtkMozEmbed object : the mozilla_engine stop recognizing any input from the vkb, except if I press 'backspace' ...
bwt, in 'commit_cb' method, it prints what I type at the console but doesn't add nothing at the HTML form (detail: it does with no context associated or if I type from the physical keyboard) ...
static gboolean gtk_moz_embed_im_context_commit_cb (GtkIMContext *ctx, const gchar *str, GtkMozEmbed *aEmbed) { gunichar uChar = 0; guint keyval = 0; gchar *text2 = (gchar *) str;
printf ("\n [GTK_MOZ_EMBED] it gets here '%s' \n", str); // the string is in UTF-8 format--iterate through the characters while (*text2) { uChar = g_utf8_get_char(text2); keyval = gdk_unicode_to_keyval(uChar); // // do something with the character here // text2 = g_utf8_next_char(text2); } }
ps: again, I'm able to pop up / hide the vkb, but not to typing into it ...
many thanks for you attention
