Arguments: basic-pane
Returns whether basic-pane has a "question mark" button in its title-bar for invoking context-sensitive help. If the user clicks this button and then clicks a dialog-item or child window of basic-pane, then the generic function context-sensitive-help is called. An application can add methods to context-sensitive-help to display help on the clicked dialog-item or child window.
Due to operating system design, this button may not be used along with the minimize or maximize buttons (see minimize-button and maximize-button). Those buttons will not appear if specified along with the help-button option.
This property should be specified by passing a help-button initarg to make-window, since this property cannot be changed on an existing window by calling setf and this generic function. (You may also specify it interactively in the inspector for a form window; the button will not appear on the form itself but will appear on the running window of the form.)
