RE: clipboard pasted text highlighting broken?

["Dugas, Alan" <alan dugas analog com>]

Hmm,,, I see what your saying.  However, if I understand you correctly, I
may have found a hack that works but shouldn't.  If I insert the following
line;

> > /* Creating entry widget to input search string */
> > entry = gtk_entry_new();
> > gtk_signal_connect(GTK_OBJECT(entry), "activate",
> > 			GTK_SIGNAL_FUNC(find_string), GTK_WIDGET(entry));
> > gtk_box_pack_start(GTK_BOX(vbox), GTK_WIDGET(entry), FALSE, FALSE, 0);
> > gtk_editable_paste_clipboard(GTK_EDITABLE(GTK_ENTRY(entry)));
> 
gtk_entry_append_text(GTK_EDITABLE(GTK_ENTRY(entry)), " ");

> > gtk_editable_select_region(GTK_EDITABLE(GTK_ENTRY(entry)), (gint) 0,
> (gint) -1);
> > gtk_widget_show(entry);
> 
all of the text in the gtkentry gets selected/highlighted properly!?!?!?
But wouldn't that mean it's somehow forcing the conditions mentioned below.
Havoc/Owen, does this hack make sense to either of you?
