Meaning of icons in class browsers

Question

Does anyone know where one can find a description of the meaning of various "icons" and / or symbols one finds next to classes and methods in various browsers?

Answer 1

Some classes define icons depending on their type. Collections, Streams, Morphs, Numbers, Exceptions, Announcements, Tests, etc. Have a look at the class hierarchy to understand the icon.

For methods there are two sets of icons. The first set is related to the class hierarchy:

• Up arrow: The method overrides a method in the superclass.
• Down arrow: The method is overridden by a method in a subclass.
• Up and down arrow: The method overrides a method in the superclass and is overridden by a method in a subclass.

The second set is used for test classes only:

• Green dot: The last run of the test method was a success.
• Orange dot: The last run of the test method was a failure.
• Red dot: The last run of the test method was an error.
• Gray dot: The test method was not recently run.

Pharo by Example describes on page 114 some of these icons in more detail. Also this website contains a slightly outdated list of icons.

If you want to understand the implementation of the different icons have a look at the following two methods: The class icons are defined in #browserIcon and the method icons in #browerIcon:selector:.
