Overview of user forms (Application mode)

In 4D, the developer can let users modify certain forms of the database in order, for example, to create custom reports, add a specific logo or, more generally, adapt the forms to their own specific needs. Once saved, a “user form” is substituted for the original form on the user machine and can be used like any other 4D form. 

The possible modifications mainly concern graphic aspects. For example, the user cannot add object methods, variables or fields. They can, however, change the entry order or add active objects from an object library. The various possibilities are set up beforehand by the developer in the Form editor of the Design mode. 

The mechanisms for setting up this system on the developer side (Design mode) are described in the User Forms section of the 4D Language Reference manual.
The current chapter describes the operation of the user form editor in Application mode.
