Method resourceExternallyUpdated

nixnote.cpp:3120–3151

This is called via global.resourceWatcher when a resource has been updated by an external program. The file name is the resource file which starts with the lid.

// has been updated by an external program.  The file name is the
// resource file which starts with the lid.
void NixNote::resourceExternallyUpdated(QString resourceFile) {
    // We do a remove of the watcher at the beginning and a
    // re-add at the end, because some applications don't actually
    // update an existing file, but delete & re-add it. The delete
    // causes NN to stop watching and any later saves are lost.
    // This re-add at the end hopefully fixes it.
    global.resourceWatcher->removePath(resourceFile);
    QString shortName = resourceFile;
    QString dba = global.fileManager.getDbaDirPath();
    shortName.replace(dba, "");
    int pos = shortName.indexOf(".");
    if (pos != -1)
        shortName = shortName.mid(0,pos);
    qint32 lid = shortName.toInt();
    QFile file(resourceFile);
    file.open(QIODevice::ReadOnly);

        resTable.updateResourceHash(lid, newHash);
        NoteTable noteTable(global.db);
