[Qt-interest] Using QAbstractTableModel with Custom Class

What are you returning in your rowCount()/columnCount() implementation
of QAbstractTableModel class?

For rowCount() you should be returning the number of items in your
QMap. (you should return QMap::size() I think)
For columnCount(), I think you mentioned 3 columns, so you can simply
return 3 here.

This should set your table dimensions right at least.

For showing proper headers, re-implement the headerData() fxn. Use
Qt::Orientation orientation to figure out what to return for
horizontal/vertical headers.

The "section" var tells you for which column header the view is
requesting data...eg:

if (role == Qt::DisplayRole && orientation == Qt::Horizontal) {
    switch(section) {
        case 0:
              return QVariant(QString("file name"));
        ...
    }
}

I'm assuming here that your worker thread has relevant API's to
extract the info when requested by the view. eg: does it have an API
to get the file name?

I don't think making your worker thread a model subclass is a good
idea. The actual data part should be kept outside of the model
implementation. Best to have worker class expose API's which the model
can query to fetch the actual data.
