Hey everyone,
I'm a complete noob to programming, know nothing about it other than a wiki article here (http://en.wikipedia.org/wiki/C_%28programming_language%29) and a few articles the admin staff posted about making effective threads in this section.
(I'm going to sound like an idiot) Just out of curiosity, how do I launch this "Hello World" script written in C for GTK+ ?
#include <gtk/gtk.h>
int main (int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *label;
gtk_init (&argc, &argv);
/* create the main, top level, window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
/* give it the title */
gtk_window_set_title (GTK_WINDOW (window), "Hello World");
/* Connect the destroy signal of the window to gtk_main_quit
* When the window is about to be destroyed we get a notification and
* stop the main GTK+ loop
*/
g_signal_connect (window, "destroy",
G_CALLBACK (gtk_main_quit), NULL);
/* Create the "Hello, World" label */
label = gtk_label_new ("Hello, World");
/* and insert it into the main window */
gtk_container_add (GTK_CONTAINER (window), label);
/* make sure that everything, window and label, are visible */
gtk_widget_show_all (window);
/* start the main loop, and let it rest there until the application is closed */
gtk_main ();
return 0;
}
I tried launching it as:
sh <filename of hello world>
But that didn't seem to work. Can someone help me through my stupidity?
Thanks for any help in advance!!! :D
