How to apply 3 or 4 if conditions at once?
Example. We have two checkbox a , b & c. I want
if a is true then b true (after click on checkbox b) and a become false so line rotated clockwise.
if b true then a true (after click on checkbox a) and b become false line rotated counterclockwise
if c true then a true (after click on checkbox a) and c become false line translate.
All transformation depend on what was the checkbox before. how to write this condition.
