Each class of MUI has its own autodoc file which can be found in this
directory. MUI autodocs feature some background information about the
class and detailed description of its attributes and methods. Make sure
to read the docs carefully before you start using them.
Besides from reading the autodocs online, you can of course find them in
the current MUI developer archive too.
Autodocs are also available for download separately as lzx archive either in
plaintext
or
HTML
format. Note that you have to hold the shift button or use "Download
link to disk" feature of your web browser for these links.
Following is an index of all MUI classes organized in a tree structure.

Important: Although some attributes are documented as BOOLeans
or BYTEs, remember that you must always pass a LONGWORD pointer to
GetAttr() and SetAttrs() (or get() and set() as MUI macros). The
following piece of code is illegal and will trash memory:
BOOL selected; // WRONG! TWO STACK BYTES AFTER
get(obj,MUIA_Selected,&selected); // selected WILL BE TRASHED!
Instead, always use LONGWORDs even for BOOLean
attributes:
LONG selected; // RIGHT! USE LONGWORDS EVEN
get(obj,MUIA_Selected,&selected); // FOR BOOL ATTRIBUTES.
