Question

我正在制作一个C＃WinForms应用程序。由于某种原因，表单的MouseMove和MouseClick事件不会被触发。（当我发现原因时，我可能会觉得自己像个白痴。）它是一个透明的表单（TransparencyKey设置为背景颜色），在图片框中有一个半透明的动画gif。我正在制作一个屏幕保护程序。有什么建议吗？

编辑： MainScreensaver.cs

    Random randGen = new Random();
    public MainScreensaver(Rectangle bounds)
    {
        InitializeComponent();
        this.Bounds = Bounds;
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        Rectangle screen = Screen.PrimaryScreen.Bounds;
        Point position = new Point(randGen.Next(0,screen.Width-this.Width)+screen.Left,randGen.Next(0,screen.Height-this.Height)+screen.Top);
        this.Location = position;
    }

    private void MainScreensaver_Load(object sender, EventArgs e)
    {
        Cursor.Hide();
        TopMost = true;
    }
    private Point mouseLocation;

    private void MainScreensaver_MouseMove(object sender, MouseEventArgs e)
    {
        if (!mouseLocation.IsEmpty)
        {
            // Terminate if mouse is moved a significant distance
            if (Math.Abs(mouseLocation.X - e.X) > 5 ||
                Math.Abs(mouseLocation.Y - e.Y) > 5)
                Application.Exit();
        }

        // Update current mouse location
        mouseLocation = e.Location;
    }

    private void MainScreensaver_KeyPress(object sender, KeyPressEventArgs e)
    {
        Application.Exit();
    }

    private void MainScreensaver_Deactive(object sender, EventArgs e)
    {
        Application.Exit();
    }

    private void MainScreensaver_MouseClick(object sender, MouseEventArgs e)
    {
        Application.Exit();
    }

摘自MainScreensaver.Designer.cs InitialiseComponent（）

    this.MouseClick += new System.Windows.Forms.MouseEventHandler(this.MainScreensaver_MouseClick);
    this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.MainScreensaver_MouseMove);

您确定自己的表单有焦点吗？如果表单没有焦点，则不会触发鼠标事件。

未触发鼠标事件
