Hello,

I've created a short example
<https://github.com/ik5/libnotify-fpc/blob/master/tests/test_notify.lpr>  to
display how to use libnotify in Pascal.
The problem is that I'm getting the following exception:

(process:7633): GLib-CRITICAL **: g_variant_new_string: assertion
`g_utf8_validate (string, -1, NULL)' failed
(process:7633): GLib-CRITICAL **: g_variant_new_string: assertion
`g_utf8_validate (string, -1, NULL)' failed
(process:7633): GLib-CRITICAL **: g_variant_new_string: assertion
`g_utf8_validate (string, -1, NULL)' failed

The text as you can see, is pure "ASCII", so what am I missing or doing
wrong here ? 

Ido
 

Forgot to call gtk_init?


That's create now gibrish as text :(

The original code that I tested was in C:
#include <libnotify/notify.h>
void main () {
  notify_init ("Hello world!");
  NotifyNotification * Hello = notify_notification_new ("Hello world", "This
is an example notification.", "dialog-information");
  notify_notification_show (Hello, NULL);
  notify_uninit ();
}

And after compiling it as follows:
gcc -o notify `pkg-config --cflags --libs libnotify` notify.c

It properly display the text, however the Pascal code does not, even with
gtk_init(@argc, @argv) :(


 

AFAIK, the use of constref for cdecl parameters is wrong in libnotify.pas.
