As discussed in today's huddle:

=============================================================================
PLAN C:


archetype LinkForce {
    link_force: component.LinkForce (datatype: datatype.LinkForce)
}


datatype LinkForce {
    enabled: ForceEnabled (datatype: Bool)
    strength: ForceStrength (datatype: Float)
    distance: Distance (datatype: Float)
}


TODO:

fn selection_ui() {
    view_property_ui::<LinkForce>(ctx, ui, view_id, self, state);
}

in re_component_ui: single and/or multiline editor for component.LinkForce

custom __init__ for `component.LinkForce`

(maybe optional?) custom native_to_pa_array for `datatype.LinkForce`
   - flexible python API input ==> NEEDED
   - custom serialization compared to the codegen'd one ===> NOT NEEDED

other plans

PLAN A:


archetype Forces {
    node_force: component.NodeForce
}


component NodeForce {
    force: datatype.NodeForce
}


datatype NodeForce {
    enabled: Bool
    strength: Float
    //....
}

-> multiline and single line edit for component.NodeForce


=============================================================================
PLAN B:



archetype LayoutMode {
    mode: component.LayoutMode (enum: None, Force, Tree)
} 

archetype LinkForce {
    enabled: ForceEnabled (datatype: Bool)
    strength: ForceStrength (datatype: Float)
    distance: Distance (datatype: Float)
}

archetype PositionForce {
    enabled: ForceEnabled (datatype: Bool)
    strength: ForceStrength (datatype: Float)
    position: Position2D
}


fn ui() {

    view_property_ui::<LayoutMode>(ctx, ui, view_id, self, state);
    let mode = ...; // manually read some view property
    
    
    switch mode {
    
        case LayoutMode::None => {
            // no additional properties
        }
        
        case LayoutMode::Force => {
            view_property_ui::<LinkForce>(ctx, ui, view_id, self, state);
            view_property_ui::<PositionForce>(ctx, ui, view_id, self, state);
        }
        
        case LayoutMode::Tree => {
            view_property_ui::<TreeLayout>(ctx, ui, view_id, self, state);
        }
    }

}
