例

次の例では、Extensible Application Markup Language (XAML) とコードを ZIndex 使用して プロパティの値を設定する方法を示します。

// Create the application's main window
mainWindow = gcnew Window();
mainWindow->Title = "Canvas ZIndex Sample";

// Create the Canvas
myCanvas = gcnew Canvas();

// Create the child Rectangle elements
myRectangle1 = gcnew Rectangle();
myRectangle2 = gcnew Rectangle();
myRectangle3 = gcnew Rectangle();
myRectangle4 = gcnew Rectangle();
myRectangle5 = gcnew Rectangle();
myRectangle6 = gcnew Rectangle();

// Set properties on the Rectangle elements
Canvas::SetTop(myRectangle1, 100);
Canvas::SetLeft(myRectangle1, 100);
Canvas::SetZIndex(myRectangle1, 3);
myRectangle1->Fill = Brushes::Blue;
myRectangle1->Width = 100;
myRectangle1->Height = 100;

Canvas::SetTop(myRectangle2, 150);
Canvas::SetLeft(myRectangle2, 150);
Canvas::SetZIndex(myRectangle2, 1);
myRectangle2->Fill = Brushes::Yellow;
myRectangle2->Width = 100;
myRectangle2->Height = 100;

Canvas::SetTop(myRectangle3, 200);
Canvas::SetLeft(myRectangle3, 200);
Canvas::SetZIndex(myRectangle3, 2);
myRectangle3->Fill = Brushes::Green;
myRectangle3->Width = 100;
myRectangle3->Height = 100;

Canvas::SetTop(myRectangle4, 300);
Canvas::SetLeft(myRectangle4, 200);
Canvas::SetZIndex(myRectangle4, 1);
myRectangle4->Fill = Brushes::Green;
myRectangle4->Width = 100;
myRectangle4->Height = 100;

Canvas::SetTop(myRectangle5, 350);
Canvas::SetLeft(myRectangle5, 150);
Canvas::SetZIndex(myRectangle5, 3);
myRectangle5->Fill = Brushes::Yellow;
myRectangle5->Width = 100;
myRectangle5->Height = 100;

Canvas::SetTop(myRectangle6, 400);
Canvas::SetLeft(myRectangle6, 100);
Canvas::SetZIndex(myRectangle6, 2);
myRectangle6->Fill = Brushes::Blue;
myRectangle6->Width = 100;
myRectangle6->Height = 100;

// Add the Rectangles to the Canvas' Children collection
myCanvas->Children->Add(myRectangle1);
myCanvas->Children->Add(myRectangle2);
myCanvas->Children->Add(myRectangle3);
myCanvas->Children->Add(myRectangle4);
myCanvas->Children->Add(myRectangle5);
myCanvas->Children->Add(myRectangle6);

// Add the Canvas as the Content of the parent Window Object
mainWindow->Content = myCanvas;
mainWindow->Show();

// Create the application's main window
mainWindow = new Window ();
mainWindow.Title = "Canvas ZIndex Sample";

// Create the Canvas
myCanvas = new Canvas();

// Create the child Rectangle elements
myRectangle1 = new Rectangle();
myRectangle2 = new Rectangle();
myRectangle3 = new Rectangle();
myRectangle4 = new Rectangle();
myRectangle5 = new Rectangle();
myRectangle6 = new Rectangle();

// Set properties on the Rectangle elements
Canvas.SetTop(myRectangle1, 100);
Canvas.SetLeft(myRectangle1, 100);
Canvas.SetZIndex(myRectangle1, 3);
myRectangle1.Fill = Brushes.Blue;
myRectangle1.Width = 100;
myRectangle1.Height = 100;

Canvas.SetTop(myRectangle2, 150);
Canvas.SetLeft(myRectangle2, 150);
Canvas.SetZIndex(myRectangle2, 1);
myRectangle2.Fill = Brushes.Yellow;
myRectangle2.Width = 100;
myRectangle2.Height = 100;

Canvas.SetTop(myRectangle3, 200);
Canvas.SetLeft(myRectangle3, 200);
Canvas.SetZIndex(myRectangle3, 2);
myRectangle3.Fill = Brushes.Green;
myRectangle3.Width = 100;
myRectangle3.Height = 100;

Canvas.SetTop(myRectangle4, 300);
Canvas.SetLeft(myRectangle4, 200);
Canvas.SetZIndex(myRectangle4, 1);
myRectangle4.Fill = Brushes.Green;
myRectangle4.Width = 100;
myRectangle4.Height = 100;

Canvas.SetTop(myRectangle5, 350);
Canvas.SetLeft(myRectangle5, 150);
Canvas.SetZIndex(myRectangle5, 3);
myRectangle5.Fill = Brushes.Yellow;
myRectangle5.Width = 100;
myRectangle5.Height = 100;

Canvas.SetTop(myRectangle6, 400);
Canvas.SetLeft(myRectangle6, 100);
Canvas.SetZIndex(myRectangle6, 2);
myRectangle6.Fill = Brushes.Blue;
myRectangle6.Width = 100;
myRectangle6.Height = 100;

// Add the Rectangles to the Canvas' Children collection
myCanvas.Children.Add(myRectangle1);
myCanvas.Children.Add(myRectangle2);
myCanvas.Children.Add(myRectangle3);
myCanvas.Children.Add(myRectangle4);
myCanvas.Children.Add(myRectangle5);
myCanvas.Children.Add(myRectangle6);

// Add the Canvas as the Content of the parent Window Object
mainWindow.Content = myCanvas;
mainWindow.Show ();

注釈

指定された elementの がvalue大きいほど、 がフォアグラウンドに表示される可能性が高elementくなります。 同様に、 に element 比較的低い valueがある場合は、 element がバックグラウンドで表示される可能性があります。 たとえば、a value が 5 の はelement、a が 4 の 上elementvalueに表示され、値が 3 の の のelement上に表示されます。 負の値が許可され、この優先順位パターンが継続されます。

値が Children 等しい ZIndex コレクションのメンバーは、ビジュアル ツリーに表示される順序でレンダリングされます。 コレクションのメンバーを反復処理することで、子のインデックス位置を Children 確認できます。
