关于自定义菜单

Question

需要自定义菜单项的外观，有三步：
1）将需要自定义外观的MenuItem的OwnerDraw设为true
2）添加MenuItem.DrawItem事件的处理函数
3）添加MenuItem.MeasureItem事件的处理函数
4）that's ok!!

注意事项：
当OwnerDraw的属性为true时，必须同时添加上面讲到的两个事件处理函数，缺一不可！

下面是两个处理函数的例子，enjoy yourself：
private void menuItem7_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{

Icon icon = new Icon("house.ico");

//e.Graphics.DrawString("hahaha",e.Font,e.b
//this.textBox1.Text+=e.Bounds.Location;
//this.textBox1.Text+=sender.GetType();


e.Graphics.FillRectangle(new System.Drawing.SolidBrush(System.Drawing.Color.Ivory),e.Bounds.Location.X,e.Bounds.Location.Y,e.Bounds.Width,e.Bounds.Height);
e.Graphics.DrawIcon(icon,e.Bounds.Location.X,e.Bounds.Location.Y);
e.Graphics.DrawString("hello",new System.Drawing.Font("arial",12),new System.Drawing.SolidBrush(System.Drawing.Color.Chocolate),e.Bounds.Location.X+22,e.Bounds.Location.Y);
this.menuItem7.Visible=true;

} private void menuItem7_MeasureItem(object sender, System.Windows.Forms.MeasureItemEventArgs e)
{
//this.textBox1.Text+=e.ItemHeight+"\r\n"; //this.textBox1.Text+=e.ItemWidth+"\r\n";
e.ItemHeight=21;
e.ItemWidth=140;
}

Answer 1

zeaing()同志，非常感谢你告诉我的解决方法，我试过了，还不错。但是，菜单项录入时的效果是如何实现的呢？是加上一个文本框吗？女孩子编程序比较的笨，还请你见谅。盼望块回复，我一定会给分的！！　

Answer 2

     问题多多，头好晕呀！
菜单是应该完全手绘吗？如果不是那我怎么在一个Form里面放两个MainMenu呢？如果是的话，那么数据结构应该怎么搞呢，我怎么才能知道那是兄弟菜单项，哪个又是子菜单项？盼知情者速速告之，小女感激不尽！！

    现在菜单项的确可以画得很漂亮,但是还有问题.一个问题是用户点击菜单项时应该让其输入菜单项的名字,这个怎么实现呢?另一个问题时,我做的是菜单编辑软件,在Form中已经有一个系统菜单了，我怎么再加入一个呀？（下面是我简单绘制的菜单，见笑见笑）
public class Form1 : System.Windows.Forms.Form
{
MainMenu mainMenu1;
MenuItem menuItem1;
MenuItem menuItem2;

/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null; public Form1()
{
//

// Required for Windows Form Designer support
//
InitializeComponent(); //
AppStartMenu();
// TODO: Add any constructor code after InitializeComponent call
//
} /// <summary>
/// Clean up any resources being used.
/// </summary>
public void AppStartMenu()
{

this.mainMenu1 = new System.Windows.Forms.MainMenu();
this.menuItem1 = new System.Windows.Forms.MenuItem();
this.menuItem2 = new System.Windows.Forms.MenuItem();
this.menuItem1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
  this.menuItem2
   });
mainMenu1.MenuItems .Add (menuItem1);
this.Menu =mainMenu1;
this.IsMdiContainer =true;
    menuItem1.OwnerDraw =true;
    menuItem2.OwnerDraw =true;
    menuItem1.DrawItem +=new System.Windows .Forms.DrawItemEventHandler(this. menuItem_DrawItem);
menuItem1.MeasureItem +=new System.Windows .Forms.MeasureItemEventHandler(this.menuItem_MeasureItem);
menuItem2.DrawItem +=new System.Windows .Forms.DrawItemEventHandler(this. menuItem_DrawItem);
menuItem2.MeasureItem +=new System.Windows .Forms.MeasureItemEventHandler(this.menuItem_MeasureItem);               
}


private void menuItem_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{             e.Graphics.DrawRectangle(new System.Drawing.Pen (System.Drawing.Color.DarkGray),e.Bounds.Location.X,e.Bounds.Location.Y,e.Bounds.Width-2,e.Bounds.Height-2);
