Description
Non-virtual entry point for arrange children. ensures common work is executed before calling the virtual ArrangeChildren function. Compute the Geometry of all the children and add populate the ArrangedChildren list with their values. Each type of Layout panel should arrange children based on desired behavior.
Optionally, update the collapsed attributes (attributes that affect the visibility) of the children before executing the virtual ArrangeChildren function. The visibility attribute is updated once per frame (see SlatePrepass). Use the option when you are calling ArrangeChildren outside of the regular SWidget Paint/Tick.
