VTE Not Showing in Scrolled Window

Hello Everyone,

I am writing a 2.90 VTE Window in GTK 3 Scrolled Window. I have the Draw signal (on the scrolled window) to the following function. Any Help would be appreciated.

Thank You

Code:

void vte_draw_cb (gpointer data)
{
      GtkWidget *vte_window;
   
      char cmd[200];
      
      sprintf(cmd,"/home/myusername/bin/myscript");
   
      char** argv=NULL;   
      GError* Err=NULL;
      GtkWidget* term;

      term=vte_terminal_new();
      g_shell_parse_argv(cmd, NULL, &argv, NULL);
      vte_terminal_fork_command_full(VTE_TERMINAL(term), 0, NULL, argv, NULL, 0, NULL, NULL, NULL, &Err);

      gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW (vte_window), GTK_WIDGET (term));
      gtk_widget_show_all (term);
}

#1. You don't have the right prototype for the callback and the callback is completely disconnected from the original scrolled window.
The prototype is:

Code:

gboolean user_function(GtkWidget* widget, CairoContext* cr, gpointer user_data)

Widget represents the scrolled window, which should be used instead of declaring a new empty GtkWidget *vte_window;
#2. I really don't think this is the way you want to go about doing things. The draw signal is related to rendering and usually you'd only use cairo calls etc. At the moment you'd be continually adding widgets (that aren't getting destroyed) every time something changes in that region to cause the window to redraw. What is the more general aim of what you want to achieve?
