Type Alias DockRailSlot 

pub type DockRailSlot = Rc<dyn Fn() -> Box<dyn Widget>>;

Factory for a rail slot widget (rebuilt on each rail rebuild).

A slot that wants to match the rail’s current item size binds DockingModel::rail_size_mode_signal — the rail rebuilds its slots whenever the size mode changes, so reading the signal in the factory is enough to keep the slot in step.
