Highlight of an ListView

[Gihu]

Hi, I’m using a ListView wich is shown in an Rectangle an have a problem with the quantity of shown ListModelElements.

My ListModel includes 8 elements but I only want to show 4 of them.

Rectangle {
      width: 340
      height: 339
 
      ListView {
        ...
 
      delegate: Component {
                        Item {
                          width: 340
                          height: 85
                       }
                      }
 
      }
    }

Rectangle {
      width: 340
      height: 339
     
      ListView {
        ...
     
      delegate: Component {
                        Item {
                          width: 340
                          height: 85
                       }
                      }
     
      }
    }

To copy to clipboard, switch view to plain text mode 

My First problem, I want to show 4 Items. 4* 85 = 340. But when I use height 340 instead of 339 for my Rectangle then always 5 elements shown.
Is using height 339 the best way to show only 4 Elements?

Second Problem is, when at start only 4 Elements shown and I navigate the highlight to the fourth Element, then the fifth Element is shown automatically.
Is it possible to prevent this?

I use Qt 5 alpha and QtQuick 2.0.

Thank You for your help.

I didn't test it but wouldn't it be simplier to do a
visible:index>4
on your delegate ?
