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

[anda_skoa]

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?
