FGeometry

Represents the position, size, and absolute position of a Widget in Slate.

API > API/Runtime > API/Runtime/SlateCore

Represents the position, size, and absolute position of a Widget in Slate. The absolute location of a geometry is usually screen space or window space depending on where the geometry originated. Geometries are usually paired with a SWidget pointer in order to provide information about a specific widget (see FArrangedWidget). A Geometry's parent is generally thought to be the Geometry of the the corresponding parent widget.
