ListView for buttons with custom onclick events. In this implementation button onclick handler is placed in model near to useful properties of button. I don't want to place them far away of button descriptions because it breaks readability.

ListItem.qml

import QtQuick 2.0

Rectangle {
  id: root
  anchors { left: parent.left; right: parent.right }
  height: 30
  color: "gray"
  radius: 15
  border.width: 1

  property alias title: textItem.text
  property alias itemColor: root.color

  signal listItemClick()

  Text {
    id: textItem
    text: ""
    anchors.centerIn: parent
  }
  MouseArea {
    anchors.fill: parent
    onClicked: listItemClick();
  }
}

main.qml

import QtQuick 2.0

Rectangle{
    width:500
    height:500

    ListView {
        width: parent.width
        height: parent.height
        clip: true
        model: mainModel
        spacing: 3
    }

    VisualItemModel {
        id: mainModel
        ListItem {
          title: "asd"
          color: "lightgray"
          onListItemClick: console.log("Evaluate Fast Fourier transformation")
        }
        ListItem {
          title: "qwer"
          color: "green"
          onListItemClick: console.log("Launch Nuclear Weapon")
        }
      }
}
