//---
// A Composable Widget is concretely a Layout (Stack, Group or CanvasLayout) to be added to the window children tree (sort of DOM).
// A Component is the struct gathering ComponentChild:
//  1) the unique composable widget ( i.e this unique root layout)
//  2) the children of this root layout (i.e. widgets or sub-components). N.B.: the other sub-layouts possibly used in the root layout children tree are not in the component struct.
// All composable widget and children widgets/sub-components have a unique field `component` corresponding to this Component structure.
// All members (layout and children) are then all connected as ComponentChild having `component` field.
// Remark: To become possibly a member of a parent component, a component has to have this field `component` to be connected to
