88 DEFAULTS is the list of buttons that are present by default. It
89 is a list of lists where the sublists are of the following form:
91 (:KEYWORD FUNC1 FUNC2 FUNC3 ...)
93 Here :KEYWORD is one of :folder or :letter. If it is :folder then
94 the default buttons in the folder and show mode buffers are being
95 specified. If it is :letter then the default buttons in the
96 letter mode are listed. FUNC1, FUNC2, FUNC3, ... are the names of
97 the functions that the buttons would execute.
99 Each element of BUTTONS is a list consisting of four mandatory
100 items and one optional item as follows:
102 (FUNCTION MODES ICON DOC &optional ENABLE-EXPR)
106 FUNCTION is the name of the function that will be executed when
107 the button is clicked.
109 MODES is a list of symbols. List elements must be from \"folder\",
110 \"letter\" and \"sequence\". If \"folder\" is present then the button is
111 available in the folder and show buffer. If the name of FUNCTION is
112 of the form \"mh-foo\", where foo is some arbitrary string, then we
113 check if the function `mh-show-foo' exists. If it exists then that
114 function is used in the show buffer. Otherwise the original function
115 `mh-foo' is used in the show buffer as well. Presence of \"sequence\"
116 is handled similar to the above. The only difference is that the
117 button is shown only when the folder is narrowed to a sequence. If
118 \"letter\" is present in MODES, then the button is available during
119 draft editing and runs FUNCTION when clicked.
121 ICON is the icon that is drawn in the button.
123 DOC is the documentation for the button. It is used in tool-tips and
124 in providing other help to the user. GNU Emacs uses only the first
125 line of the string. So the DOC should be formatted such that the
126 first line is useful and complete without the rest of the string.
128 Optional item ENABLE-EXPR is an arbitrary lisp expression. If it
129 evaluates to nil, then the button is deactivated, otherwise it is
130 active. If it isn't present then the button is always active."
131 ;; The following variable names have been carefully chosen to make code
132 ;; generation easier. Modifying the names should be done carefully.
