(defvar image-load-path) (defmacro mh-tool-bar-define (defaults &rest buttons) "Define a tool bar for MH-E. DEFAULTS is the list of buttons that are present by default. It is a list of lists where the sublists are of the following form: (:KEYWORD FUNC1 FUNC2 FUNC3 ...) Here :KEYWORD is one of :folder or :letter. If it is :folder then the default buttons in the folder and show mode buffers are being specified. If it is :letter then the default buttons in the letter mode are listed. FUNC1, FUNC2, FUNC3, ... are the names of the functions that the buttons would execute. Each element of BUTTONS is a list consisting of four mandatory items and one optional item as follows: (FUNCTION MODES ICON DOC &optional ENABLE-EXPR) where, FUNCTION is the name of the function that will be executed when the button is clicked. MODES is a list of symbols. List elements must be from \"folder\", \"letter\" and \"sequence\". If \"folder\" is present then the button is available in the folder and show buffer. If the name of FUNCTION is of the form \"mh-foo\", where foo is some arbitrary string, then we check if the function `mh-show-foo' exists. If it exists then that function is used in the show buffer. Otherwise the original function `mh-foo' is used in the show buffer as well. Presence of \"sequence\" is handled similar to the above. The only difference is that the button is shown only when the folder is narrowed to a sequence. If \"letter\" is present in MODES, then the button is available during draft editing and runs FUNCTION when clicked. ICON is the icon that is drawn in the button. DOC is the documentation for the button. It is used in tool-tips and in providing other help to the user. GNU Emacs uses only the first line of the string. So the DOC should be formatted such that the first line is useful and complete without the rest of the string. Optional item ENABLE-EXPR is an arbitrary lisp expression. If it evaluates to nil, then the button is inactive, otherwise it is active. If it isn't present then the button is always active." ;; The following variable names have been carefully chosen to make code ;; generation easier. Modifying the names should be done carefully.
