Hi all, Where: GoLUG: https://meet.jit.si/golug When: Wednesday, 5/7/2025 7pm sharp Eastern Daylight time Arrive 15 minutes early for Microphone check & discussion Who: Steve Litt, Troubleshooter, Developer, Tech Writer What: Introduction to Tcl/Tk GUI applications Last month David Billsbrough introduced us to the Tcl computer language. 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. SteveT Steve Litt GoLUG Publicity Coordinator
