We'd like to set up a widget in a form that would export data to a file, e.g. to export a table as a CSV file on the Desktop. There is a widget option Set Action > File > Write Data, which produces the code template:

f = new QFile( '/path/to/file' );

f.open( QIODevice.OpenMode.WriteOnly );

f.write( ... );

f.close();

But I can't find any further documentation on how to customize this code to make it work.

Thanks!
