- Prison Code Breaker Diary -

I have introduced about GtkVBox in the previous lesson; however, GtkHBox is basically the same as GtkVBox. The only difference is the horizontal arrangement of GtkHBox.
Reference GtkHBox

Things do the same.
So just try to mix GtkHBox and GtkVBox you can do a small application like this:Why not make it a practice?

Detail: an Gtk+ application, like a phone dial

When you done, you can check out my source below, it's pretty handy though...
