Unclear Map Definitions
Walux last edited by Walux
Hi Qt community ,
I just found the documentation definitions of :
-mapfromItem and maptoItem
kind of unclear , and i thought maybe i'll understand more if someone would volunteer to show me the difference between these , and especially between (from and to)
I'll be grateful for any help.
Nice regards ,

I'd recommend reading this article which explains everything fairly well: Coordinate System
As the article explains, each graphics item maintains it's own coordinate system. The methods you are referring to are used to translate coordinates between those items, between the items and the scene and so on.
I hope that reading that article will help, otherwise feel free to ask if clarification is needed.
