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 */
