What this demonstrates

Independent page layouts in one document

Sections divide a document into independently formatted ranges. Each section can define its own page geometry, columns, borders, headers, footers, and numbering behavior.

How it works

TXTextControl.sections exposes the complete document structure. The demo reads each Section, including its text range and SectionFormat, and builds the navigator directly from the loaded document.

The section containing the input position is returned by SectionCollection.getItem. Its read-only format property exposes mutable objects for page size, margins, and borders, while Selection.sectionFormat provides a convenient route for editing the current section.

Page size and margins use the document's current page unit, while page-border widths use twips. This document uses hundredths of an inch, so the demo displays page geometry in inches and converts the point-based margin presets before applying them.

A missing page border has zero-width lines. The colored-border action first assigns a visible width to the line-width properties supported by the active client and then colors every side independently. Only the active section changes; neighboring sections retain their own layout.
