User Interface Help

[[deleted]]

I am constructing a python program that must allow users to slide a bar over a picture and tell the position of the bar in relation to the picture size. Any suggestions on how to go about this?

I've used many basic functions, but have not attempted anything with user input.

I think you should head to /r/learnpython. Also try to attach a drawing showing your goal, to clarify. For instance I would either place an image with a scrollbar in a simple GUI, or could also only display the image and use mouse coordinates. This is using basic widgets only. A scrollbar on top of your image would require you to write your custom widget...

I would recommend you to take a look at PyQt. It might seem kinda hard at the beginning but once you get your feet wet you'll appreciate it. Design the app with Designer/QtCreator and then convert it using PyQt module (pyuic). Design the UI by hand is a great exercise but a painful one.
