Thanks Peter for the reply!
To reproduce the problem on your e-text reader in newlisp I had:

1) Commented the lines

# LEONARDO (GTK:gtkp "gtk_text_view_set_editable" entry 0)
# LEONARDO (GTK:gtkp "gtk_text_view_set_cursor_visible" entry 0)

2) Added the line

(GTK:gtkp "gtk_server_connect" entry "focus-out-event Trial")

To reproduce the problem you can:

1) Place the focus in the textview (I also wrote some text)
2) Try to load a file

I think the problem is in the blinking cursor..... so if it's not visible
the issue doesn't show up.
I have only one GTK version on my computer and the gtk_check_version say:

Gtk+ version too new (major mismatch)

I really don't know what's happening.
I have Gtk 2.6.7 and I verified this version number with the Gtk Demo
I have checked my path and in my harddisk I have found only one
I will try on linux and let you know the results.

Thanks again and compliments for your e-text application.

Hi Leonardo,

Unfortunately I cannot reproduce your problem. The system I use is Win2000,
server 2.0.5 and GTK 2.6.8-1.

In my e-text reader, which I programmed with newLisp, I can connect the
out-event' signal to the TextView widget without any warnings. My code looks
like this:

(GTK:gtkp "gtk_server_connect" entry "focus-out-event Trial")

The variable 'entry' contains the pointer to the TextView widget. It is the
last line in my TextView definitions. The logfile shows:

SCRIPT: gtk_settings_get_default
SERVER: 15617320
SCRIPT: gtk_widget_set_name 15696056 textview
SCRIPT: gtk_server_connect 15696056 focus-out-event Trial
SCRIPT: gtk_frame_new NULL
SERVER: 15779744

The bug-report you mention concerns GTK 2.0.x, so I assume it is not valid
your GTK 2.6.x.

So it appears you suffer from a GTK 2.0.x problem. You can check your
GTK version with the command "gtk_check_version".

Please make sure you have only one GTK installation on your machine, and
you have the correct GTK DLL's in your path. If this is the case, maybe you
could try to upgrade to the latest GTK environment, which is downloadable

If all this does not work out, you could try to perform a 'grabfocus'
on the TextView first.

Also you could try to use my e-text viewer with newLisp and add the same
signal, to see if the problem occurs again.

The GTK-server currently connects additional signals with
the 'g_signal_connect' command. So connecting additional signals with
the 'g_signal_connect_after' command cannot be performed (yet).

Please let me the outcome of this problem.

Best regards
