My Lenovo laptop has two programs, such as a taskbar, that show network status and battery status. I am trying to find what these types of widgits are called. Unfortunately, my google-foo returns results only to minimize programs in the taskbar.
I'm not even sure if these are system tray applications or taskbar applications. but anyway, please help me find an API link or even a better tutorial.
I want to create a Work Week Widgit that displays the current work week number of this widget. I program mainly in python, but I want to learn another language to make this tool.
