C#最小化到系统托盘实现

目标:程序点击关闭后,弹出一个对话框,选择退出,最小化,或者取消.然后系统托盘双击,可以打开最小化的程序,右键有菜单,菜单里有个"选项",可以设置每次点击关闭按钮时是否弹出这个对话框.

难点:增加一个"下次不再提示"的comboBox到对话框中.

使用到的知识:

1. 非模态对话框: CloseDialog.Show();

模态对话框: CloseDialog.ShowDialog();

2. 禁止拉伸对话框: this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;

3. 最小化到托盘的实现:

3.1.加notifyicon控件notifyIcon，为控件notifyIcon的属性Icon添加一个icon图标

3.2.添加事件：

privatevoid QPan_SizeChanged(object
sender, System.EventArgs e)

{

if(this.WindowState
== System.Windows.Forms.FormWindowState.Minimized)

{

this.QPan_MiniMizedToTuoPan();

}

}

//最小化到托盘，函数

publicvoid QPan_MiniMizedToTuoPan()

{

this.Hide();

this.ShowInTaskbar =
false;

this.notifyIcon.Visible =
true;

}

4.托盘双击：

//双击托盘图标

privatevoid notifyIcon_DoubleClick(object
sender, System.EventArgs e)

{

this.QPan_OpenFromTuoPan();

}

//从托盘返回，函数

Publicvoid QPan_OpenFromTuoPan()

{

this.Visible =
true;

this.Show();

this.ShowInTaskbar =
true;

this.WindowState = System.Windows.Forms.FormWindowState.Normal;

this.notifyIcon.Visible =
true;

}

5.右键菜单：

5.1.增加一个ContextmenuStrip

5.2.增加菜单项：

// TuoPanContextMenuStrip

//

this.TuoPanContextMenuStrip.Items.AddRange(new
System.Windows.Forms.ToolStripItem[] {

this.TrayOptions,

this.TraySeparator1,

this.TrayOpen,

this.TrayExit});

this.TuoPanContextMenuStrip.Name =
"TuoPancontextMenuStrip";

this.TuoPanContextMenuStrip.Size =
new System.Drawing.Size(112,
76);

//

// TrayOptions

//

this.TrayOptions.Name =
"TrayOptions";

this.TrayOptions.Size =
new System.Drawing.Size(111,
22);

this.TrayOptions.Text =
"Options";

this.TrayOptions.Click +=
new System.EventHandler(this.OpenSettingOptions);

//

// TraySeparator1

//

this.TraySeparator1.Name =
"TraySeparator1";

this.TraySeparator1.Size =
new System.Drawing.Size(108,
6);

//

// TrayOpen

//

this.TrayOpen.Name =
"TrayOpen";

this.TrayOpen.Size =
new System.Drawing.Size(111,
22);

this.TrayOpen.Text =
"Open";

this.TrayOpen.Click +=
new System.EventHandler(this.OpenQPan);

//

// TrayExit

//

this.TrayExit.Name =
"TrayExit";

this.TrayExit.Size =
new System.Drawing.Size(111,
22);

this.TrayExit.Text =
"Exit";

this.TrayExit.Click +=
new System.EventHandler(this.CloseQPan);

//

5.3.给菜单项增加事件：

//退出

privatevoid CloseQPan(object
sender, System.EventArgs e)

{

boolCloseFromExitMenu = true;

Application.Exit();

}

//打开

privatevoid OpenQPan(object
sender, System.EventArgs e)

{

this.QPan_OpenFromTuoPan();

}

//打开选项设置

privatevoid OpenSettingOptions(object
sender, System.EventArgs e)

{

this.NewOptionDialog.ShowDialog();

}
