QQ界面含图片动态分组菜单的实现[C#]

源码传了两次，显示上传成功，但都没见着,那就将就着看吧,挺简单的:
问题点说明:1)主要用到了Dock属性:(略)
                    2)SendToBack()方法:将控件移到 Z 顺序的后面。如果控件是另一个控件子级，那么将子控件移到 Z 顺序的后面。
                    3)listView的SelectedIndexChanged事件:会触发两次,怎么解决请看程序中代码解释

新建一个WinForm工程,添加三个button(当主菜单),btnListOne,btnListTwo,btnListThree,
                                             一个listview(容纳子菜单):listView1,
                                             一个imageList:imageList1(给菜单加图标[片]

自己设置三个button的dock初始值:可以top,也可为bottom,和listview的anchor值,程序中的值为:Top, Bottom, Left, Right

代码如下:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace QQList{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { //做初始化显示处理 btnListOne_Click(null, null); } private void btnListOne_Click(object sender, EventArgs e) { //调节控件位置 this.btnListTwo.Dock = DockStyle.Bottom; this.btnListThree.SendToBack(); this.btnListThree.Dock = DockStyle.Bottom; this.listView1.Dock = DockStyle.Top; this.btnListOne.SendToBack(); this.btnListOne.Dock = DockStyle.Top; //清空原有菜单 this.listView1.Items.Clear(); //加子菜单 this.listView1.Items.Add("菜单1-1",1); this.listView1.Items.Add("菜单1-2",2); this.listView1.Items.Add("菜单1-3",3); } private void btnListTwo_Click(object sender, EventArgs e) { //调节控件位置 this.btnListTwo.Dock = DockStyle.Top; this.btnListOne.SendToBack(); this.btnListOne.Dock = DockStyle.Top; this.listView1.Dock = DockStyle.Bottom; this.btnListThree.SendToBack(); this.btnListThree.Dock = DockStyle.Bottom; //清空原有菜单 this.listView1.Items.Clear(); //加子菜单 this.listView1.Items.Add("菜单2-1",4); this.listView1.Items.Add("菜单2-2",5); this.listView1.Items.Add("菜单2-3",6); } private void btnListThree_Click(object sender, EventArgs e) { //调节控件位置 if (this.btnListThree.Dock == DockStyle.Bottom) { this.btnListThree.Dock = DockStyle.Top; this.btnListTwo.SendToBack(); this.btnListTwo.Dock = DockStyle.Top; this.btnListOne.SendToBack(); this.btnListOne.Dock = DockStyle.Top; this.listView1.Dock = DockStyle.Bottom; } //清空原有菜单 this.listView1.Items.Clear(); //加子菜单 this.listView1.Items.Add("菜单3-1",7); this.listView1.Items.Add("菜单3-2",8); this.listView1.Items.Add("菜单3-3",9); } /// <summary> /// 给listview加一个事件，当选择的是不同的时候，做出相应的处理 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void listView1_SelectedIndexChanged(object sender, EventArgs e) { //关于listView的SelectedIndexChanged事件的特别说明: //在选择项改变的时候，取消原来的选中项时，this.listView1.SelectedIndices.Count == 0; //在选择到新的项的时候， this.listView1.SelectedIndices.Count > 0; //所以会导致会触发两次：listView1_SelectedIndexChanged事件，故在这里加个判断，防止执行两次 if (this.listView1.SelectedIndices.Count > 0) { //你要执行的代码 MessageBox.Show("您选择的菜单是: " + this.listView1.FocusedItem.Text.ToString()); } } }}
