TDocStd_Document Class Reference

The contents of a TDocStd_Application, a document is a container for a data framework composed of labels and attributes. As such, TDocStd_Document is the entry point into the data framework. To gain access to the data, you create a document as follows: Handle(TDocStd_Document) MyDF = new TDocStd_Document The document also allows you to manage: More...

## Detailed Description

The contents of a TDocStd_Application, a document is a container for a data framework composed of labels and attributes. As such, TDocStd_Document is the entry point into the data framework. To gain access to the data, you create a document as follows: Handle(TDocStd_Document) MyDF = new TDocStd_Document The document also allows you to manage:

- modifications, providing Undo and Redo functions.
- command transactions. Warning: The only data saved is the framework (TDF_Data)
