Content

Table containing attributes defining a attributes of content drawn inside of element.

Content

You can draw inside an element by setting its content, using element:setContent(). It only takes a function as a parameter, which will be given the ref, x and y attributes. It's needed to add atributes x and y to position of any element which is drawn in content for make it move together with main element when is dragged. It's possible to redefine content dimensions at runtime with element:setContentDimensions(width, height).

Scrolling

Scrolling is set in the content atribute using scroll atribute. You can later set the scroll for a specific axis manually using element:setScroll({ x, y }) and retrieve scroll using element:getScroll()
