QListView, set maximum content height

Question

I want to use QListView to display a number of records, Set-up so far:

mplvRecs = new QListView(this);
mpsiModel = new QStandardItemModel(DataSets::mscuint16Rows,
                                   DataSets::mscuint16Cols, this);

mscuint16Rows and mscuint16Cols:

const quint16 DataSets::mscuint16Rows = 4;
const quint16 DataSets::mscuint16Cols = 1;

What I want to do is set the height of the list view to the height of exactly 4 rows, however it seems to be at least double that size. How can I fix this?
