back to virtual keyboard stuff, I'm wondering how could a non-gtk entry (mozilla password html form in this case) could hide the inputed text (after showing for a short period of time - default behaviour), like if I set gtk_entry_set_visibility of a GtkEntry to FALSE. I've been looking over the GtkEntry source code (at http://maemo.org/lxr/source/gtk%2B/gtk/gtkentry.c) and its way seems to be to gtk_gobject dependent. Is there any workaround ? Aaron ? :)

First off, vte is just another Gtk widget, and it uses a Gtk input method.
It just so happens that vte is the widget that provides most of the
functionality for xterm. You can examine the source code for vte for more
information.
There is no "delete" key on the virtual keyboard, so I would have to
assume that you are getting that from your keyboard. When the virtual
keyboard is used to send a backspace, it will result in a key-press and
key-release event (since there is no simple way to represent this
character using the GtkIMContext's "commit" event). So, you'll need to
handle these special keys in your key-press and key-release event
handlers. Basically, if the GtkIMContext doesn't handle the key-press or
key-release in the calls to gtk_im_context_filter_keypress(), then you may
want to handle certain key events or just blindly handle all that get
through the filter.
You can build vncviewer in debug mode (use ./configure --help to determine
the proper option) and debug it to see how it handles a virtual keyboard
backspace.
And finally, I will again refer you to the GtkEntry class, which is a
relatively simple class that demonstrates how to properly use input
methods. In getting input methods working properly in vncviewer, I
studied the source code of xterm, vte, GtkEntry, and other input-driven
widgets.
