You can create a theme that makes highlighted widget look equally as
non-highlighted.
Here is a quick hack using gtk event filtering. It blocks all activation
events. It works well, but probably blocks more that you
want - for example tap to menu bar and moving stylus over different
menus does not work, as it needs notify signals as well. It needs some
experimenting and improvement.
Maybe it should not block enter/leave signals if button is pressed
(stylus is on the screen) and generate leave signal if button is
released (stylus was lifted). Maybe use g_signal_handler_block() applied
on "enter" and "leave" signals. Maybe use gtk_get_event_widget() in the
filter and block events only for selected widget.
#include <gtk/gtk.h>
static void
filter (GdkEvent *event, gpointer data)
{
if (event->type != GDK_ENTER_NOTIFY && event->type != GDK_LEAVE_NOTIFY)
gtk_main_do_event (event);
}
void
gtk_module_init (gint *argc, gchar ***argv)
{
gdk_event_handler_set (filter, NULL, NULL);
}
Please let me know your result. I am thinking about improvement of libgtkstylus.
