Gecko Documentation Primary Index

The goal of this document is to provide extensive links to documentation on the Gecko Layout components and classes. There are two sections containing links to the documents, and there is overlap between these sections by design. First, there is a 'Topics' section, where documentation is listed by generic topics, more or less free-form and ad-hoc. Second, there is a 'Class and Component' section, where specific classes and components are listed, mapping naturally to the source code. All documents should be indexed in both sections, so pick the index that corresponds to what you are thinking about. A Tech Notes section is also included to help contributors find information on small topics and issues, including simple 'How To' cookbooks.

For information about the structure of layout documents, see the Gecko Documentation Overview and the Layout Documentation Templates (High Level Design Template / Detailed Design Template).
