1) Elements
The elements (Choose Boxes, Static Text etc.) you can see as an object on the screen. The ID appears in the status bare when the mouse is over an element (Illustration). The ID appears as well in the title of the Evaluation Dialog. In this dialog you define what’s only to the element.2) Definitions
You cannot see the Definition as object on the screen. The Definition is an invisible object, containing colors, font names, items of lists etc. When you create a Choose Box you create the element choose box with typical ID 1005 and you create an invisible definition with typical ID 102. The object 1005 will retain that he is a user of 102. If you create a Choose box using the Duplication with permanent like then you create only the element and the definition ID is taken from the selected element used for that duplication. That’s the way you get a Chain of Definitions. The ID of a definition appears only in the title of the Definitions Dialog. In this dialog you define colors, lists etc. The choices made in this dialog apply to all element(s) belonging to chain of definitions (see exercise 2). Validaters are forced by the program to become a chain of definition. Therefore they always have the same looking. Note:3) Messages
1) Length and height belong to the element, they do not belong to the definition.
2) All links (Choose Box to a Validater, Dependent Element to Independent Element, Referenced Text to Elements, Active List to Elements) are produced through ID's.
3) The elements linked to a Validater form a Chain of Validation. This chain may contain Dependent Element and Independent Element.
Messages are visible through the Message Editor where the ID can be seen on each tab. The links between messages and elements are established through the Evaluation Dialogs (on his first and second tab). The Info tab of the Message Editor allows the inverse way: find all elements linked to a given message.To be aware of that structure may be useful in the use of the menus (for instance those of the menu selection) and dialogs.
