General Layout Attributes

Container Attributes

indent 

(default: 0) The amount of space between the leftmost (or topmost) widget and the end of the left (or top) margin.

create 

(default: true) Determines whether or not this node actually creates a widget using a platform widget implementation. Examples of noncreating containers are row, column, and overlay. This attribute is not settable from within the layout description.

spacing 

(default: 10) The amount of space to be put between multiple children of the container. This value can also contain an array, which will be iterated in turn to determine the spacing between two child widgets. Example: spacing: [ 5, 10, 15 ] will yield a container with 5 pixels between child widget 1 and 2, 10 pixels between child widget 2 and 3, and so forth.
