Toolbox/Menus

This page of developer code and/or digital audio documentation is part of a collection of pages for learning about our code. We aim to increasingly add interactive diagrams to these pages and over time connect better to the doxygen documentation.

Constructing Menus

Here's the top level of the Help menu.

Here, below, is the definition of menus from HelpMenus.cpp that creates it. The three sections of the menu are named "Basic", "Other" and "" (i.e no name) which is to make it easier for other menu definitions to add additional menu items in later in the appropriate section of the menu. XXO( "something" ) are the text strings that appear in the menu and are translated. wxT("something") are the command IDs that are used by scripting and that are supposed not to change if we change the visible name of the command. FN(OnSomething) are the names of the functions called for that menu item.

Making Images of the Menus

A JSON description of the Audacity menus is available in this wiki at WIT_Audacity_Menus. This description is obtained by invoking the GetInfo command in Audacity. WIT pulls the description from the wiki and uses it in constructing the images and image maps in the manual.
