ListView with VisualItemModel

[huluyige]

Hi everyone,

I'm using a VisualItemModel for a listView. for example

@ListView{
id:myList
height:??????
width:360
model:myModel
}
VisualItemModel{
id:myModel
Rectangle{
id:myRec
width:360
height:40
}
}@

As you can see above, i want the list view'height is equal to the model's height, specially to the myRec'height(40), in the example.

So my question is : how can we do a property binding between a listView and its VisualItemModel?

Thanks in advance

further question is: how can i do it if the model is in another qml. that's to say, i use

@model: VisualItemModel{}@

to intialize listView's model.

yes,

in the VisualItemModel.qml, we add a property to the model
@VisualItemModel{
id:myModel
property real myHeight:myRec.height
Rectangle{
id:myRec
width:360
height:40
}
}@

and in the view.qml, we create an instance of visualItemModel, and bind the two heights
@ListView{
id:myList
height:myModel.myHeight
width:360
model:myModel
VisualItemModel{
id:myModel
}
}@

Thanks! I am doing some stuff on lists and it is almost useful as an example.
