It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken.
Limits in rubber sheet geometry.
The rubber sheet analogy is really just to help you visualize a physical surface for which things like the distance between two points isn t really meaningful.
Why topology is called rubbersheet geometry.
Concept of topology rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight.
Topology studies properties of spaces that are invariant under any continuous deformation.
For example a square can be deformed into a circle without breaking it but a figure 8 cannot.

It provides simple fixed placement of windows where you specify the exact size and location of one window called the slave within another window called the master the placer also provides rubber sheet placement where you specify the size and location of the slave in terms of the dimensions of the master so that the slave changes size.
A circle can be stretched into a square with a rubber band but you can t stretch a figure eight into a circle without tearing.
The placer is a geometry manager for tk.
And maybe visualizing stretched and deformed open discs might help get you used to the idea.
