NAME

Document::DoImport - instance method

TEMPLATE

importCommand = Command * DoImport(istream & inputStream, FileType * fileType)

SPECIFIERS

public virtual

DESCRIPTION

DoImport is called by the method Import and must perform the actual import operation. fileType is the type of the file which has been selected in the import dialog and checked by the method CanImportDocument. The name of the file has been used to create the inputStream. DoImport will normally use the inputStream for reading. But by means of the fileType, which also contains the file name (see class FileType), it is also possible to open and read the file in a different way. DoImport should create and return an undoable command. For example, a document dealing with text would read the text from the file and create a "paste" command with that text.
The default implementation just returns gNoChanges. Method is sometimes overridden.

ARGUMENTS

istream & inputStream: input stream which to import data from
FileType * fileType: the type of the file from which to import data. fileType has been checked by the method CanImportDocument.

RETURN ARGUMENT

Command * importCommand: an undoable command which will actually insert the imported data into the document
