Python Transformation & Scrolling Issue

[0rfeo]

Hi everyone!
I was wondering if I can get some help from you because me knowedge is very limitated:

• 1.- Firstly, I want to know how make transfomation on python, I mean not such general thing but only if some of you know something like rotating things or just move something in python. It's because I want to customize my sceens with something, just like snowblossom in tutorial. Or if you know about somewhere were I can find information about.
  
  2.- Secondly, does anyone of you know how to set up scrolling value to buttons?, I mean, I have a vp and a scrollingbox and I want to scroll it up and down using buttons instead of bars or mousewheel. I don't know if it is possible or not so I want to know at least not how but if it is possible.

Here is the code for second question:

Code: Select all

screen random_screen:
    
    tag menu 
    
    window:
        style "gm_root"
    
    frame:
         
         style_group "ramdom_screen"
         
         side "c b r":
            area (600,200, 170, 270)

            viewport id "vp":
                draggable True
                has vbox spacing 10
                
                
                textbutton "1" action ShowMenu ("preferences")
                textbutton "2" action ShowMenu ("preferences")
#              etc

Thank you so much for reading this.
