Development

A place to gather miscellaneous development notes.

Generate and view doxygen code documentation from the rosegarden directory as follows:

doxygen
xdg-open build/doc/html/index.html

Or substitute your favorite browser for xdg-open.

These used to be available online at http://rosegarden.sourceforge.net/code_doc but that is no longer maintained.

These are short explanations that have come up on the Rosegarden developers' mailing list at one time or another, sometimes with a bit more detail added in the wiki.

See also the rosegarden-devel archives.

There are several plain-text documents found in the Rosegarden source code repository (browse).

These ones are either vaguely interesting, or at least not hopelessly out of date:

NOTE I didn't realize this page simply linked to SVN. These documents are no longer available. We should just move them into the wiki and update them as we go, but I am not going to finish that anytime soon. The documents that have not yet been rescued can be found in http://rosegarden.svn.sourceforge.net/viewvc/rosegarden/branches/obsolete/docs/

• Overall code structure
• Creating Events and their properties
