Now, the processing the drawing on the screen is introduction, than we will need the DrawingArea widget.
The GtkDrawingArea widget is used for creating custom user interface elements.

2. DrawingArea Widget Synopsis Object Hierarchy
#include <gtk/gtk.h>
Struct GtkDrawingArea;
GtkWidget* gtk_drawing_area_new (void);
void gtk_drawing_area_size (GtkDrawingArea *darea,
gint width,
gint height);

gint x,
gint y) ;
