Function to execute a program

[Pisanu Prasertnopakun]

Hi all, I'm a newbie gtk-programmer and wanna ask something. Which function in gtk-library is use to run a program such as "xterm" or "xclock"? I design myself a simple program with a simple button and want to run an execute program after button click. Here i want to pack it in my "xclock" function. Please help..  My simple code..   /* Begin test1.c */ #include<gtk/gtk.h> /* Function: xclock  *  * Abstract: This is a callback function for hello  *  * Return: NN  */ static void xclock ( GtkWidget *widget,       gpointer data) { // HERE i find a function to run a simple program like xclock!! // i should ! be "run(xclock);" or something like that..  have somebody an idea? } /* Function: delete_event  *  * Abstract: This is a function for delete event.  *  * Return: TRUE  - you don't want the window to be destroyed.  *         FALSE - GTK will emit the destroy signal.  */ static gboolean delete_event( GtkWidget *widget,          GdkEvent *event,          gpointer data) {   g_print ("delete evernt occured ");   return TRUE; } /* Function: destroy  *  * Abstract: This a callback function for destroy.  *  * Return: NN  */ static void destroy( GtkWidget *widget,        gpointer data) {   gtk_main_quit(); } int main( int argc, char *argv[]) {   Gtk! Widget *window;   GtkWidget *button1;   gtk_init (& amp;argc, &argv);   /* create a new window */   window = gtk_window_new (GTK_WINDOW_TOPLEVEL);   g_signal_connect (G_OBJECT (window), "delete_event",       G_CALLBACK (delete_event), NULL);   gtk_container_set_border_width (GTK_CONTAINER (window), 10);   button1 = gtk_button_new_with_label ("XCLOCK");   /* When the button receives the "clicked" signal, it will call    * the function xclock() passing NULL as its argument. The xclock()    * signal could come from here, or the window manager.    */   g_signal_connect (G_OBJECT (button1), "clicked",       G_CALLBACK (xclock), NULL);   /* This will cause the window to be destroyed by calling    * gtk_widget_destroy(window) when "clicked". Again, the destroy    * signal could come from here, or the window manager. */  ! ; g_signal_connect_swapped (G_OBJECT (button1), "clicked",        G_CALLBACK (gtk_widget_destroy),        G_OBJECT (window));   gtk_container_add (GTK_CONTAINER (window), button1);   gtk_widget_show (button1);   gtk_widget_show (window);   gtk_main ();     return 0; } /* END OF FILE test1.c */ --  Pisanu Prasertnopakun Bienroder Weg 54/1810 38108 Braunschweig, Germany Tel. +49-(0)531-221 7133 Cell. +49-(0)176-2007 1885 Email: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] ______________________________________________________________________________ 38xTestsieger - WEB.DE FreeMail - Deutschlands beste E-Mail!
