示例1: MeasureOverride
Protected Overrides Function MeasureOverride(ByVal availableSize As Size) As Size
Dim desiredSize As New Size()
For Each child As UIElement In VisualChildren
child.Measure(availableSize)
' do something with child.DesiredSize, either sum them directly or apply whatever logic your element has for reinterpreting the child sizes
' if greater than availableSize, must decide what to do and which size to return
Next child
' desiredSize = ... computed sum of children's DesiredSize ...
' IMPORTANT: do not allow PositiveInfinity to be returned, that will raise an exception in the caller!
' PositiveInfinity might be an availableSize input - this means that the parent does not care about sizing
Return desiredSize
End Function
