Nowadays, we mostly interact with our computers using a Graphical User Interface. The operating system as a whole uses several elements of the GUI to make the user experience more human-like. Can users get to unleash some of the GUI's power? The answer is yes: welcome to Zenity, a GTK+ application that works in GNU/Linux, BSD and Windows. In this short article I will show you how to create a simple script that interacts with the user using the GUI.
One of the biggest navigational issues with any operating system is using program menus. Windows users have to open the Start Menu, scan for the program, realize that the program is probably in the subfolder under the programmer’s name, scan the appropriate subfolder, and then click on the program’s icon. Macintosh users must open Finder, find and click on the Applications folder, and then search for the program’s name. GNOME and KDE users have an advantage: they have categories in their respective Applications and K menus.
