Re: [gtk-list] How to invoke Xclient?

["Shawn T . Amundson" <amundson gimp org>]

The function required by the "activate" signal is different
than that of system().

So, you do not want to invoke system() directly.  You want to do 
something like this: (I'm tired so this may not be 100% typed 
correctly.)

void
sys_callback (GtkMenuItem *menuitem, gpointer data)
{
  gchar *command;
  command = (gchar*) data;

  system(command);
}

gtk_signal_connect (GTK_OBJECT(menuitem), "activate",
                    GTK_SIGNAL_FUNC (sys_callback), (gpointer)"kterm &");

You can determine the correct prototype for a signal function by looking
at the widget's class.  For menu item that is GtkMenuItemClass, which has:

  void (* activate)      (GtkMenuItem *menu_item);

(This is from gtkmenuitem.h.)

Append gpointer to that and you have the prototype.
