首先,当然要引入NotifyIcon控件。
private System.Windows.Forms.NotifyIcon
notifyIconServer;
this.notifyIconServer = new
System.Windows.Forms.NotifyIcon(this.components);
接下来设置控件的各项属性:
//
// notifyIconServer
//
this.notifyIconServer.ContextMenu =
this.contextMenuTray;//指定上下文菜单
this.notifyIconServer.Icon =
((System.Drawing.Icon)(resources.GetObject("notifyIconServer.Icon")));//指定图标
this.notifyIconServer.Text
= "My Server";//指定鼠标悬停显示
this.notifyIconServer.MouseDown += new
System.Windows.Forms.MouseEventHandler(this.notifyIconServer_MouseDown);
this.notifyIconServer.DoubleClick
+= new System.EventHandler(this.notifyIconServer_DoubleClick);
//
// contextMenuTray 上下文菜单
//
this.contextMenuTray.MenuItems.AddRange(new
System.Windows.Forms.MenuItem[]
{
this.menuItem1,
this.menuItem2});
//
// menuItem1
//
this.menuItem1.Index =
0;
this.menuItem1.Text = "打开 Chat Server";
this.menuItem1.Click += new
System.EventHandler(this.menuItem1_Click);
//
// menuItem2
//
this.menuItem2.Index = 1;
this.menuItem2.Text =
"退出程序";
this.menuItem2.Click += new
System.EventHandler(this.menuItem2_Click);
用户点击窗体的“关闭”小按钮时,并不真正关闭窗体,而是将程序放到系统托盘。
private
void ChatForm_Closing(object sender, System.ComponentModel.CancelEventArgs
e)
{
e.Cancel = true; //
取消关闭窗体
this.Hide();
this.ShowInTaskbar =
false;
this.notifyIconServer.Visible =
true;//显示托盘图标
}
notifyIcon的双击事件,可以恢复程序窗体:
private void
notifyIconServer_DoubleClick(object sender, System.EventArgs e)
{
this.Show();
if (this.WindowState ==
FormWindowState.Minimized)
this.WindowState =
FormWindowState.Normal;
this.Activate();
}
附加要求:单击鼠标左键也可调出一菜单。
解决方案如下:
首先声明一个上下文菜单:
//
// contextMenuLeft 左键菜单
//
this.contextMenuLeft.MenuItems.AddRange(new
System.Windows.Forms.MenuItem[]
{
this.menuItem3});
//
// menuItem3
//
this.menuItem3.Index = 0;
this.menuItem3.Text =
"关于……";
由于不能在notifyIcon上直接显示上下文菜单,只有创建一个Control作为容器,这是权宜之计,应该有更好的方法吧。
private
void notifyIconServer_MouseDown(object sender,
System.Windows.Forms.MouseEventArgs
e)
{
if(e.Button==MouseButtons.Left)
{
Control control = new
Control(null,Control.MousePosition.X,Control.MousePosition.Y,1,1);
control.Visible
= true;
control.CreateControl();
Point pos = new
Point(0,0);//这里的两个数字要根据你的上下文菜单大小适当地调整
this.contextMenuLeft.Show(control,pos);
}
}
