[Function]
system: make-object-set
name &optional default-handler
This function makes a new object set. Name is a string used only for purposes of identifying the object set when it is printed. Default-handler is the function used as a handler when an undefined operation occurs on an object in the set. You can define operations with the serve-operation functions exported the extensions package for X events (see section x-serve-mumbles). Objects are added with system:add-xwindow-object. Initially the object set has no objects and no defined operations.
[Function]
system: object-set-operation
object-set operation-code
This function returns the handler function that is the implementation of the operation corresponding to operation-code in object-set. When set with setf, the setter function establishes the new handler. The serve-operation functions exported from the extensions package for X events (see section x-serve-mumbles) call this on behalf of the user when announcing a new operation for an object set.
[Function]
system: add-xwindow-object
window object object-set
These functions add port or window to object-set. Object is an arbitrary Lisp object that is associated with the port or window capability. Window is a CLX window. When an event occurs, system:serve-event passes object as an argument to the handler function.
