配置条件は、AdornerPanel 上の装飾の位置とサイズを柔軟に設定できるようにする値のセットを構築するために使用されます。

例

コントロール内にレール装飾を配置する方法を次のコード例に示します。詳細については、「チュートリアル : コントロール内でのレールの実装」を参照してください。

' Place the slider in the adorner panel.
Dim placement As New AdornerPlacementCollection()
AdornerPanel.SetHorizontalStretch(skewSlider, AdornerStretch.Stretch)
AdornerPanel.SetVerticalStretch(skewSlider, AdornerStretch.None)

' Use layout space for the adorner panel.
' If render space were used, the slider would skew along with the button.
panel.CoordinateSpace = AdornerCoordinateSpaces.Layout

' The adorner's width is relative to the content.
' The slider extends half the width of the control it adorns.
placement.SizeRelativeToContentWidth(0.5, 0)

' Center the adorner within the control.
placement.PositionRelativeToAdornerWidth(0.5, 0)

' The adorner's height is the same as the slider's.
placement.SizeRelativeToAdornerDesiredHeight(1.0, 0)

' Position the adorner within the control it adorns.
placement.PositionRelativeToAdornerHeight(1.0, 0)

AdornerPanel.SetPlacements(skewSlider, placement)

// Place the slider in the adorner panel.
AdornerPlacementCollection placement = new AdornerPlacementCollection();
AdornerPanel.SetHorizontalStretch(skewSlider, AdornerStretch.Stretch);
AdornerPanel.SetVerticalStretch(skewSlider, AdornerStretch.None);

// Use layout space for the adorner panel.
// If render space were used, the slider would skew along with the button.
panel.CoordinateSpace = AdornerCoordinateSpaces.Layout;

// The adorner's width is relative to the content.
// The slider extends half the width of the control it adorns.
placement.SizeRelativeToContentWidth(0.5, 0);

// Center the adorner within the control.
placement.PositionRelativeToAdornerWidth(0.5, 0);

// The adorner's height is the same as the slider's.
placement.SizeRelativeToAdornerDesiredHeight(1.0, 0);

// Position the adorner within the control it adorns.
placement.PositionRelativeToAdornerHeight(1.0, 0);

AdornerPanel.SetPlacements(skewSlider, placement);
