Update statusIcon gtk pixbuf

[SomeIrishGuy]

private StatusIcon trayIcon;

in the constructor i have

Constructor
{
this.trayIcon = new StatusIcon(getStatusIconPixbuf());
......
}


private Pixbuf getStatusIconPixbuf() // returns a generated pixbuf
{
.......
}




this works fine, but i would like to be able to change the pixbuf
icon in the statusmenu at periodical intervals using a timer

i seems to cause havok though, as the menu no longer draws correctly and the pixbuf just goes blank

i presume i've done something to the main thread (cross invocation exception), but i cant find any documentation on how to invoke a change managed by a delegate for this event.

Thanks.
Dave.

Use Application.Invoke with a delegate that sets the status icon.

in Elapsed event of timer you must do :

Gtk.Application.Invoke(delegate{
        //change your icon here
});
