This month Steve Litt takes it a step farther, introducing Tk, the GUI (Graphical User Interface) tool. Tk was written primarily in Tcl, and even though it's now available for most modern computer languages, it's easiest in its native Tcl. Starting with a Hello World Tk application, we'll then go on to explore widgets such as labels, buttons and inputs, discussing geometry managers and detailing the grid geometry manager. Changing widget properties at runtime is demonstrated. Time permitting, we'll explore a practical green/yellow/red/black speech timer.
