title-reader

Generic Function

Package: common-graphics

Arguments: check-box-column-mixin

An accessor on a check-box column of a grid-widget. Returns (or sets with setf) the name of a function which will be called in order to obtain the string to display in each check-box grid cell. The function should take an arbitrary grid-row's data-object as its only argument, and return a string to display in that row. For example, here is the title-reader function for the "Full Time?" column of the employee grid example of the Navigator dialog Examples tab:

(defun full-time-p-title-reader (employee)
  ;; Show a string such as "Trent's full-time" 
  ;; beside the check-box.
  (format nil "~:(~a~)'s full-time" (name employee)))
