title: Autofill QComboBox with data from database
body: <p>I have created a <code>QComboBox</code> delegate which I use for a single column of a <code>QTableView</code> (each cell of that column is an individual <code>combobox</code>), the data which I want to display in my <code>combobox</code> returns from the database as a string of id's separated by a <code>;</code><br>
  My question is, how do I populate my <code>combobox</code> with this data retrieved by the database. </p>
  
  <p>To clarify: the column in question retrieves specific Id's (4 digit strings), sometimes an object may have multiple Id's (separated by <code>;</code>), I want to create a <code>combobox</code> for the cells with multiple Id's so the user can select which one they want to work with.</p>
