About 4D Write Pro objects

Home

4D v20 R7

In 4D applications, 4D Write Pro documents are handled using Object type variables (for more information, refer to the _O_C_OBJECT command).

Once referenced in memory, a 4D Write Pro object can be:

displayed and modified through a 4D form using the form object named "Write Pro Area," provided that the form area has the same name as the object variable (see Defining a 4D Write Pro area).
handled programmatically by commands from several themes (see below).
exported to an HTML document on disk using the WP EXPORT DOCUMENT command.

You can handle 4D Write Pro objects using 4D commands from several themes:

Dedicated commands from the 4D Write Pro theme; these commands are described in this chapter.
Objects (Forms) commands, to address formatting and object property features; for more information, please refer to the Using commands from the Objects (Forms) theme section.
Styled Text commands, to address content features; for more information, please refer to the Using commands from the Styled Text theme section.
Objects (Language) commands, to work with 4D Write Pro object attributes; please refer to the Storing 4D Write Pro documents in 4D Object fields section.
