[Request] Tutorial on Scroll Bars for GUI's

[DrEinsteinium]

Hey everyone,

 

I have been trying to add a scroll bar to my GUI for a while now but with no luck, and I was curious if someone would take the time to write a detailed tutorial for it. I and many other would appreciate it, and it would be a great contribution to the community.

 

As for what it's scrolling through, you could have it scroll through anything from a list of GUI slots to a list of GuiButtons, or even a list of pictures. Thank you so much.

Override the mouse events, use some scrollPos variable...

Thanks for the example. I've gotten the mouse wheel to work but I'm a little bit confused with the actually clicking and dragging of the scroll bar. Can you explain how it works?

I've seen yours ben. You inspired me to make mine into a widget, however mine isn't as fancy as yours, because you clip the buttons >.>; <3

 

Here is my git. I managed to get the click/drag working with the built in methods of GuiContainer. Now I just have to write the algorithm to scroll through my buttons.
