Detailed Description

Number to differentiate different windows of the same class.

This number generally implicitly passes some information, e.g. the TileIndex or Company associated with the window. To ease this use, the window number is lenient with what it accepts and broad with what it returns.

Anything that converts into a number and ConvertibleThroughBase types will be accepted. When it's being used it returns int32_t or any other type when that's specifically requested, e.g. VehicleType type = window_number or GetEngineListHeight(window_number) in which the returned value will be a VehicleType.
