Zoom form entity
A Zoom Form generates a form used to select a value from a list and return the value to the program. It is generally related to a CRUD form field to assist the user with completing the form data entry.
A Zoom form entity is represented as a 4fdz file which can be opened and edited in Form Designer.
When a Zoom form entity is implemented from the diagram, the 4fdz file is created as well as 4gl source files that contain the logic to allow a user to pick a value from a list that is displayed in a form in a popup window.
Any changes to the Zoom form entity properties in the BA diagram or in the 4fdz file are included in the subsequent re-generating of the program code.
The generated code can be customized.
Properties can be set specify how the form should behave during the various states (DISPLAY, SEARCH).
