範例

在下列程式碼範例中，會說明如何設定滑軌裝飾項在控制項中的定位。如需詳細資訊，請參閱逐步解說：在控制項中實作滑軌。

' 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);
