It might be a typo on the page for ScrollViewWidget/object:setSize().

[weiwei0530]

In the Gotchas chapter, it says: "Calling this function will mess with the x position of the scrollbar. To fix this, call object:setScrollHeight() after calling this method."

I'm a bit confused because an issue with the x position should typically be fixed by adjusting the horizontal axis. After testing, it seems the correct fix is to use object:setScrollWidth() instead of object:setScrollHeight().

I'm not a senior developer, so this issue might need further verification by someone more experienced. Thanks a lot.
