[SailfishDevel] Problem with QQmlListProperty

[Markus Svensson]

Hi guys,

I'm trying to expose my database layer to QML via a QQmlListProperty - however I'm running into problems... I've probably set it up wrong - but I can't figure out where. My C++ skills are a bit rusty after years and years of Java work... :)

This is my setup code:

QQmlListProperty<Note> NoteList::notes() {
    return QQmlListProperty<Note>(this, &_notes, &append,
                                             &size,
                                             &at,
                                             &clear);
}

These are the actual methods I'm trying to pass in to the list property: 

static void append(QQmlListProperty<Note> *property, Note* value) {
    NoteList *list = (NoteList*) property;
    list->addNote(value);
}

static void clear(QQmlListProperty<Note> *property) {
    NoteList *list = (NoteList*) property;
    list->clearNotes();
}

static int size(QQmlListProperty<Note> *property) {
    NoteList *list = (NoteList*) property;
    return list->countNotes();
}

static Note* at(QQmlListProperty<Note> *property, int index) {
    NoteList *list = (NoteList*) property;
    return list->noteAt(index);
}

When I compile - I get this:
/Users/markus/Documents/SailfishOS/build-SilicaNote-MerSDK_SailfishOS_i486_x86-Debug/notelist.o:-1: In function `QQmlListProperty'
/usr/include/qt5/QtQml/qqmllist.h:72: error: undefined reference to `NoteList::append(QQmlListProperty<Note>*, Note*)

File not found: /usr/include/qt5/QtQml/qqmllist.h
:-1: error: collect2: ld returned 1 exit status

Does anyone have any idea what I'm doing wrong?

The broken code is in a separate branch on GitHub - https://github.com/Ortofta/SilicaNote/tree/borked - feel free to look around.
It is a WIP and learning experience - so don't expect greatness.

Thanks!
