4D Write Pro documents can be displayed and edited manually in a 4D form object, named 4D Write Pro. This object is available as part of the last tool (Plug-in Area, Web Area, etc.) found in the object bar:

A 4D Write Pro form area is configured by means of standard properties found in the Property List, such as Object Name and Variable Name, Coordinates, Entry, Display and Appearance, and/or Events.

The Variable Name property can be used in the language as a reference to the 4D Write Pro area. Note that the variable must be of the Object type (for more information, refer to the C_OBJECT command).
"Entry" properties manage basic features for text entry:
- Enterable: enables you to lock/unlock the area in order to allow or prevent editing
- Auto Spellcheck: available for 4D Write Pro areas
- Context Menu: allows you to enable/disable the context menu in Application mode (see the Using a 4D Write Pro area section)
- Selection always visible: handles text selection as in standard text areas.
