You may wish to begin by reading the [text widget conceptual overview](TextWidget.

html) which gives an overview of all the objects and data types related to the text widget and how they work together.

A TextMark is like a bookmark in a text buffer; it preserves a position in the text. You can convert the mark to an iterator using get_iter_at_mark. Unlike iterators, marks remain valid across buffer mutations, because their behavior is defined when text is inserted or deleted. When text containing a mark is deleted, the mark remains in the position originally occupied by the deleted text. When text is inserted at a mark, a mark with “left gravity” will be moved to the beginning of the newly-inserted text, and a mark with “right gravity” will be moved to the end.

Note that “left” and “right” here refer to logical direction (left is the toward the start of the buffer); in some languages such as Hebrew the logically-leftmost text is not actually on the left when displayed.

Marks are reference counted, but the reference count only controls the validity of the memory; marks can be deleted from the buffer at any time with delete_mark. Once deleted from the buffer, a mark is essentially useless.

Marks optionally have names; these can be convenient to avoid passing the TextMark object around.

Marks are typically created using the create_mark function.
