如何让mdi 主窗体响应click事件

Question

请求大神指导

Answer 1

click事件对应于响应mouse的click，

 Form2 form = new Form2();
 form.MdiParent = this.MdiParent; 
 form.Show();

form2的click事件，可以通过定义一个委托方法于MdiParent类型中，form中的mouse click 直接调用

MdiParent 的事件方法。

你好，

首先, 确认Form1 的 IsMdiContainer 设置为 true.

然后初始化 Form1 和Form2, 设置Form1 作为 Form2's MdiParent:

// Form1.IsMdiContainer should be true
Form1 form1 = new Form1();

// This automatically adds form2 into form1's MdiChildren collection
Form2 form2 = new Form2();
form2.MdiParent = form1;

在 Form2 的代码，你可以参考一下下面的代码。

public class Form2 : Form {
    // Include as data member so we only instantiate one Form3
    Form3 _form3;

    public Form2() {
        InitializeComponent();
        Button1.Click += new EventHandler(Button1_Click);
    }

    private void Button1_Click(object sender, EventArgs e) {
        if(_form3 == null) {
            _form3 = new Form3();
            // Set Form3's parent to be Form1
            _form3.MdiParent = this.MdiParent;
        }
    }
}
