Long scroll menus

Long scrolling menus:

[USING SCROLLBAR]

1. The problem here is i don't know how to "cut" things: i draw my menu, suppose 600x1000px in total (width, height) but my canvas only supports 600x400, so somehow i need to cut only between (e,400+e)px of the height in order to properly draw things. That's easy with OPENGL clipping window, but with pygame? maybe some opengl should be used.

2. Draw a scrollbar, that's not difficult. Also that scrollbar should handle mouse input: if the user clicks between scrollbar rectangle (and holds) it should move itself and scroll the page.

[USING PAGES]
That's more easy, just create a menu with several pages, if user press any pair of keys (LEFT, RIGHT) the menu must change between page x and x+1, x in (1,n). The number of the page must be drawn somewhere (bottom right corner maybe?)

One possible solution might be to scroll down the items and when at the bottom it loads a new page and scrolling starts again... Ideally with a little animation to show the transition. Might be tricky if scrolling up and down through that border area though.

I'll work on this in the following weeks

I've been trying to get pagination to work with a selector, but onchange doesn't seem to allow you to load a new menu.

Do you have any working example?

I am trying to use it for my flatpak-manager for SteamOS. The code I was talking about can be found here: https://github.com/sharkwouter/flatpak-manager/blob/master/flatpak-manager-steamos/flatpakmanager_steamos/gui.py#L97

If you'd like to test that code, you can execute flatpak-manager/flatpak-manager-steamos/flatpak-manager-steamos script to test it. It is specific to Linux, though, and requires flatpak to be installed.

I could make a short script which shows what I'm trying to do better. Not sure it if is very clear from this code. Let me know if that is needed.

Hi, I prefer a short script to test the behaviour of the selector

No problem, I made a simplified version with just the paged menu here: https://gist.github.com/sharkwouter/ec465d36f6f9fd1570e17511c570f36c

Don't pay too much attention to calculation which determines how many pages there are. It can be off by one with different range sizes.
