C#托盘程序的制作

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); } } |
