Hi, I have two problems: 1)How can I open a file(such as text or image ) with default application? 2)How can I set my program as default application to open specific type of file? I wonder if GTK provide some function to carry out such operations? And what preference materials can I look for? (something like windows function ShellExecuteA(NULL, "open",.....)) Thanks advance! -- Sincerely, Alfred Young _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
