An event point is a place in the execution of an Appx process where a designer can insert code to enhance the standard Appx behavior. These insertion points loosely relate to points where the Appx engine interfaces with external functions, such as screen display, keyboard input, or disk access. At these points an Appx designer can place code to add business rules to tailor the application to a specific industry or company policy.
These interactions can take place at different stages of a process. Some points of interaction would be when a process starts or ends, when a frame is executed or completes, when an image is displayed, when a user makes an entry through the keyboard or mouse, or when a record is read or written.
