Setting a VisualItemModel for a Repeater appends to the Repeater, rather than replacing.

Setting a VisualItemModel for a Repeater has the effect of appending the items to the Repeater.

Take a look at the example code below. Click on one of the grey buttons to set the Repeater content to 3 Rectangles. Click the other grey button to set 3 different Rectangles. The Repeater ends up with 6 rectangles, even though Repeater.count says 3...

import Qt 4.7

Rectangle {
width: 200
height: 800

Column {
y: 200
Repeater

{ id: fred }

}

VisualItemModel {
id: model0
Rectangle

{ width: 100; height: 20; color: "red" }

Rectangle

{ width: 100; height: 20; color: "green" }

Rectangle

{ width: 100; height: 20; color: "blue" }

}
VisualItemModel {
id: model1
Rectangle

{ width: 100; height: 20; color: "yellow" }

Rectangle

{ width: 100; height: 20; color: "orange" }

Rectangle

{ width: 100; height: 20; color: "pink" }

}

Rectangle {
width: 100
height: 30
color: "grey"
Text

{ text: "Set to model0" }

MouseArea {
anchors.fill: parent
onClicked:

{ fred.model = model0; }

}
}

Rectangle {
y: 40
width: 100
height: 30
color: "grey"
Text

{ text: "Set to model1" }

MouseArea {
anchors.fill: parent
onClicked:

{ fred.model = model1; }

}
}

Text

{ y: 80; text: "Number of items = " + fred.count }

}
