Detailed Description

Base class for import filters.

Licensed under the GNU GENERAL PUBLIC LICENSE. See LICENSE.GPL for details.

This class inherits CAFile and is the base class for any specific import filter (eg. LilyPond, CanorusML, MusicXML etc.).

If a developer wants to write a new import filter, he should: 1) Create a new class with the base class CAImport 2) Implement CAImport constructors and at least importDocumentImpl() function which returns the new CADocument. 3) Register the filter (put a new fileformat to CAFileFormats and add the filter to open/save dialogs in CACanorus)

Optionally: Developer should change the current status and progress while operations are in progress. He should also rewrite the readableStatus() function.

The following example illustrates the usage of import class:

CAMyImportFilter import();
import.setStreamFromFile("jingle bells.xml");
import.importDocument();
import.wait();
setDocument( import.importedDocument() );
CACanorus::rebuildUI();

In Python the example is even more direct using the string as an input method:

lilyString = '\\relative c { \\clef "treble" \\time 4/4 c4 d e f | f e d c | c1 \\bar "|." }'
myImport = CALilyPondImport( lilyString )
myImport.importVoice()
myImport.wait()         
voice = myImport.importedVoice()

Note: Both stream and string can be used both in Canorus and scripting. The example is only for illustration.
