Most of the time, while the cursor position is good, the
insertion point does not match the cursor position. If this
apply to what you really want, then you should use the
<TT
CLASS="LITERAL"
>gtk_text_set_point()</TT
> function. If you want
to set the insertion point at the current cursor position, use
the following:</P
><TABLE

BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="PROGRAMLISTING"
> gtk_text_set_point(GTK_TEXT(text),
gtk_editable_get_position(GTK_EDITABLE(text)));</PRE
></TD
></TR
></TABLE
><P
>If you want the insertion point to follow the cursor at
all time, you should probably catch the button press event,
and then move the insertion point. Be careful : you'll have to
catch it after the widget has changed the cursor position
though. Thomas Mailund Jensen proposed the following
code:</P
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="PROGRAMLISTING"
>static void
insert_bar (GtkWidget *text)
{
/* jump to cursor mark */
gtk_text_set_point (GTK_TEXT (text),
gtk_editable_get_position (GTK_EDITABLE (text)));
gtk_text_insert (GTK_TEXT (text), NULL, NULL, NULL,
"bar", strlen ("bar"));
}
int
main (int argc, char *argv[])
{
GtkWidget *window, *text;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
text = gtk_text_new (NULL, NULL);
gtk_text_set_editable (GTK_TEXT (text), TRUE);
gtk_container_add (GTK_CONTAINER (window), text);
/* connect after everything else */
gtk_signal_connect_after (GTK_OBJECT(text), "button_press_event",
GTK_SIGNAL_FUNC (insert_bar), NULL);
gtk_widget_show_all(window);
gtk_main();
return 0;
