SnappingModel class abstract

Base class for all MultiStateSheet snapping models used in conjunction with SnappingBehavior.

This abstract class provides the foundation for calculating snapping offsets based on the state of the sheet and its components. Implementations define how snapping positions are determined.

See also:

• FractionSnappingModel: A snapping model based on fractions of the viewport height.
• SizeSnappingModel: A snapping model based on sheet sizes in pixels.
• OffsetSnappingModel: A snapping model based on fixed pixel offsets from the top of the viewport.
• ComponentsSnappingModel: A snapping model based on the sizes of specific sheet components.
