Copying from one score to another in a Musescore 2.0 plugin

Hi,

I'm a little confused by the new plugin architecture of Musescore 2.0 (it doesn't help that I don't have any experience with QML, sorry I'm working on that...).

I would like to copy a selection of a score to a new one and I've managed to copy the notes (i.e., the pitches) by looking at the "notenames" plugin and using two cursors in parallel in the two scores. However, I cannot figure out where I should get/set the duration of each note and how to copy rests as well.

Here's an excerpt of the part of my code where I need some hints to solve my problem:

var scoreCopy = newScore("copy.mscz", "Piano", 8);
var cursor2 = scoreCopy.newCursor();
cursor2.rewind(0);

while (cursor.segment && (fullScore || cursor.tick < endTick)) {
if (cursor.element){
if(cursor.element.type == Element.CHORD){
var notes = cursor.element.notes;
for (var i = 0; i < notes.length; i++) {
cursor2.setDuration(1, cursor.element.duration); //???
cursor2.addNote(notes[i].pitch);
} // end for note
}
if(cursor.element.type == Element.REST){
//???
}
} // end if ELEMENT
cursor.next();
cursor2.next();
} // end while segment

Could somebody please provide me or point me to an example showing how this is supposed to work in a plugin for Musescore 2.0?

Generally speaking, where should I look for a reference of the available objects/properties/methods? The Musescore Debugger or the manual in the Musescore Plugin Creator (the latter seems rather incomplete to me)?

Thanks
Francesco
