Cusomize QFileDialog: add new column to the file view of the QFileDialog

[polynom]

Yes, method:
QVariant QFileDialogProxyModel::data(const QModelIndex &index, int role/* = Qt:isplayRole*/)
is called, but I don´t get a index (index.column() == 4) and probably therefore my columns are empty.
Should I call createIndex and create a new QModelIndex which will have a column==4?
But I think, that I will modify the main model and not the proxy model.

Yes, try overwriting the index() method and handle creation of indexes for your column yourself.
Another thing, just to make sure it isn't he cause, would be to always return 5 in the columnCount method,

I have overwritten the index() method and handle the custom column in the proxy model itself.
Now a custom column is displayed with a custom header and custom contents. perfect.
But I have another problem with the selection of a file.
I cannot choose a file anymore. I can select a file, but no file is displayed in the "File Name" QLineEdit and the "OK" Button is disabled.
The following methods are also overwritten in the QFileDialogProxyModel class: (the signature i have already checked)

virtual QItemSelection mapSelectionToSource ( const QItemSelection & proxySelection ) const;
virtual QItemSelection	mapSelectionFromSource ( const QItemSelection & sourceSelection ) const;
 
QItemSelection	QFileDialogProxyModel::mapSelectionFromSource ( const QItemSelection & sourceSelection ) const{
	return QSortFilterProxyModel::mapSelectionFromSource(sourceSelection);
}
 
 
 
QItemSelection QFileDialogProxyModel::mapSelectionToSource ( const QItemSelection & proxySelection ) const{
	return QSortFilterProxyModel::mapSelectionToSource(proxySelection);
}

virtual QItemSelection mapSelectionToSource ( const QItemSelection & proxySelection ) const;
virtual QItemSelection	mapSelectionFromSource ( const QItemSelection & sourceSelection ) const;

QItemSelection	QFileDialogProxyModel::mapSelectionFromSource ( const QItemSelection & sourceSelection ) const{
	return QSortFilterProxyModel::mapSelectionFromSource(sourceSelection);
}



QItemSelection QFileDialogProxyModel::mapSelectionToSource ( const QItemSelection & proxySelection ) const{
	return QSortFilterProxyModel::mapSelectionToSource(proxySelection);
}

To copy to clipboard, switch view to plain text mode 

but the debugger doesn´t stop here at no time.
I expected that I get a debugger stop at Line 5 or Line 11.

Maybe also needs to implement mapFromSource/mapToSource?
