Question

我在向项目添加点击事件时遇到了一些问题。主要逻辑是正确的，但我需要一些点击事件的帮助。该项目在Canvas上放置了一些按钮，我想在它们上添加一个click事件。

我正在使用Kinect v2，每次都找到一个Body，每次都找到一个SpineMid关节，项目会使用正多边形的形状在身体周围绘制一些按钮。

在我的情况下，问题是我无法点击按钮，因为它们在每一帧都被清除。

每次我找到关节时都会调用函数InitializeButtons（所以，我每帧创建新按钮然后清除它们）所以基本上不可能点击它们，没有时间查看按钮的内容变化：他们立即被替换了！

这是我调用函数的代码：

foreach (Body body in bodies){
   foreach (var item in body.Joints){
               JointType jointType = item.Key;
               Joint joint = item.Value;
               if (joint.JointType == JointType.SpineMid) {
                  InitializeButtons(100, 200, center, verticies, 300)
               }
   }
}

这是InizializeButtons函数的代码：

 private void InitializeButtons(int height, int width, Point center, Point[] verticies, int radius)
    {
        Button test_button1 = new Button() { Background = Brushes.Aquamarine, Height = height, Width = width, Content = "I'm test button1!" };
        Button test_button2 = new Button() { Background = Brushes.Aqua, Height = height, Width = width, Content = "I'm test button2!" };
        Button test_button3 = new Button() { Background = Brushes.Beige, Height = height, Width = width, Content = "I'm test button3!" };
        Button test_button4 = new Button() { Background = Brushes.BurlyWood, Height = height, Width = width, Content = "I'm test button4!" };
        Button test_button5 = new Button() { Background = Brushes.Bisque, Height = height, Width = width, Content = "I'm test button5!" };

        test_button1.Click += test_button1_Click;

        canvas.Children.Add(test_button1);
        canvas.Children.Add(test_button2);
        canvas.Children.Add(test_button3);
        canvas.Children.Add(test_button4);
        canvas.Children.Add(test_button5);

        Canvas.SetLeft(test_button1, 0);
        Canvas.SetTop(test_button1, 0);

        Canvas.SetLeft(test_button2, 0);
        Canvas.SetTop(test_button2, 0);

        Canvas.SetLeft(test_button3, 0);
        Canvas.SetTop(test_button3, 0);

        Canvas.SetLeft(test_button4, 0);
        Canvas.SetTop(test_button4, 0);

        Canvas.SetLeft(test_button5, 0);
        Canvas.SetTop(test_button5, 0);

        buttons = new List<Button> { test_button1, test_button2, test_button3, test_button4, test_button5 };

        verticies = Polygon.CalculateVertices(buttons.Count, radius, 18, center);

        int i = 0;
        foreach (Button button in buttons)
        {
            Canvas.SetLeft(button, verticies[i].X);
            Canvas.SetTop(button, verticies[i].Y);
            i++;
        }

        verticies = null;
    }

    void test_button1_Click(object sender, RoutedEventArgs e)
    {
        Button clickedButton = (Button)sender;

        clickedButton.Content = "let's try it";          
    }

有什么方法可以超越它吗？任何帮助都非常感谢。
