Event Driven programming in c Linux Based

In a GUI program events occur typically when we click on the window, type a character, close the window, repaint the window, etc. We have chosen the GTK library version 2.0 to create the GUI applications. Here, GTK stands for Gimp’s Tool Kit.

below is the first program that uses this toolkit to create a window on the screen.

/* mywindow.c */
# include
int main ( int argc, char *argv[ ] )
GtkWidget *p ;
gtk_init ( &argc, &argv ) ;
p = gtk_window_new ( GTK_WINDOW_TOPLEVEL ) ;
gtk_window_set_title ( p , "Sample Window" ) ;
g_signal_connect ( p, "destroy", gtk_main_quit, NULL ) ;
gtk_widget_set_size_request ( p, 300, 300 ) ;
gtk_widget_show ( p ) ;
gtk_main( ) ;
return 0 ;

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming

My 1st Program...

void main ()
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();

Next Step...


void main ()
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();
