为什么我的图片框不能响应MouseClick事件? [英] Why wont my picturebox respond to a MouseClick event?

问题描述

您好，我正在制作一个简单的应用程序，但我注意到一些很奇怪的东西，因此为了帮助解释此问题，我创建了一个测试应用程序.

我创建了2个图片框，第一个图片是使用代码创建的，并将其命名为"pic".我使用工具箱创建的第二个图片框，只是将其保留为标准的"picturebox1"名称.

因此，我将两个图片框的背景色都设置为黑色，并为它们创建了一个事件，当我单击它们时，它们会将背景色更改为蓝色.

现在这是一个问题，当我单击"picturebox1"时，它变为蓝色.但是，当我单击图片"时却没有，为什么会发生这种情况?如何使活动在图片"上正常播放?

这是我的示例代码:

Hi, I am making a simple application and I noticed something quite strange so to help explain this problem I created a test application.

I created 2 pictureboxes, the first one I created using code and named it "pic". The second picturebox I created using the toolbox and just left it with the standard "picturebox1" name.

So moving along, I set both of the pictureboxes backcolor to black and I made an event for both of them that will change the backcolor to blue when I click on them.

Now heres the problem, when I click on "picturebox1" it changes to the color blue. But when I click on "pic" it doesn''t, why does this happen? How can I make the event work on "pic"?

here is my sample code:

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        PictureBox pic = new PictureBox();

        private void Form1_Load(object sender, EventArgs e)
        {
            pic.BackColor = Color.Black;

            panel1.Controls.Add(pic);

            pic.Location = new Point(200, 100);
        }
        private void pic_MouseClick(object sender, MouseEventArgs e)
        {
            pic.BackColor = Color.Blue;
        }

        private void pictureBox1_MouseClick(object sender, MouseEventArgs e)
        {
            pictureBox1.BackColor = Color.Blue;
        }
    }
}

我将不胜感激！

谢谢，

推荐答案

Hi在其中，您必须初始化事件，右键单击InitializeComponent()方法->转到定义并复制并粘贴事件处理程序

Hi Inside this you have to initialize your event right click on InitializeComponent() method -> go to definition and copy and paste event handler

public Form1()
       {
           InitializeComponent();

       }

this.pictureBox1.MouseClick += new System.Windows.Forms.MouseEventHandler(this.pictureBox1_MouseClick);

this.pic.MouseClick += new System.Windows.Forms.MouseEventHandler(this.pic_MouseClick);
