C#实现类似QQ的隐藏浮动窗体、消息闪动

功能简介

当语音客服系统登录成功进入主界面时，本聊天工具将会自动隐藏在左下角位置，当鼠标移动到左下角时，自动弹出，当鼠标移开聊天窗体时，自动隐藏。如果想让聊天窗体固定在桌面，只要拖动一下聊天窗口，让它不停留在边界位置就可以了。隐藏和悬浮方式类型QQ。

1. 系统主界面

当点击最小化按钮时，

在电脑右下角会显示任务图标，点击任务图标

，将会在左下角位置弹出。

主界面各部分介绍：

a) 消息列表：该区域的功能主要是显示消息记录。

b) 发送消息：输入要发送的消息进行发送，默认群聊，输入消息后，按回车键或者点击“发送”按钮，将进行消息发送。

c) 坐席人员：显示所有已登录客服系统的坐席人员，显示方式：名称（状态）

d) 通知：记录坐席上下线记录

实现浮动：

#region 停靠悬浮

internal AnchorStyles StopDock = AnchorStyles.None;

private void StopRectTimer_Tick(object sender, EventArgs e)
{
//如果鼠标在窗体上，则根据停靠位置显示整个窗体
if (this.Bounds.Contains(Cursor.Position))
{
switch (this.StopDock)
{
case AnchorStyles.Top:
this.Location = new Point(this.Location.X, 0);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
case AnchorStyles.Left:
this.Location = new Point(0, this.Location.Y);
break;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
break;
}
}
else  //如果鼠标离开窗体，则根据停靠位置隐藏窗体，但须留出部分窗体边缘以便鼠标选中窗体
{
switch (this.StopDock)
{
case AnchorStyles.Top:
this.Location = new Point(this.Location.X, (this.Height - 3) * (-1));
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - 5);
break;
case AnchorStyles.Left:
this.Location = new Point((-1) * (this.Width - 3), this.Location.Y);
break;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - 2, this.Location.Y);
break;
}
}
}

private void MainFrm_LocationChanged(object sender, EventArgs e)
{
if (this.Top <= 0)
{
this.StopDock = AnchorStyles.Top;
}
else if (this.Bottom >= Screen.PrimaryScreen.Bounds.Height)
{
this.StopDock = AnchorStyles.Bottom;
}
else if (this.Left <= 0)
{
this.StopDock = AnchorStyles.Left;
}
else if (this.Left >= Screen.PrimaryScreen.Bounds.Width - this.Width)
{
this.StopDock = AnchorStyles.Right;
}
else
{
this.StopDock = AnchorStyles.None;
}
}

有消息来时，不断闪动图标，添加一个定时器，不断切换该图标，监听，消息列表，如果有文字改变，则开启定时器。

int i = 0; //先设置一个全局变量 i ,用来控制图片索引,然后创建定时事件,双击定时控件就可以编辑
        private Icon ico1 = new Icon("img/q1.ico");
        private Icon ico2 = new Icon("img/q2.ico"); //两个图标 切换显示 以达到消息闪动的效果

//定时器 不断闪动图标
private void timer1_Tick(object sender, EventArgs e)
{
//如果i=0则让任务栏图标变为透明的图标并且退出
if (i < 1)
{
this.notifyIcon1.Icon = ico2;
i++;
return;
}
//如果i!=0,就让任务栏图标变为ico1,并将i置为0;
else
this.notifyIcon1.Icon = ico1;
i = 0;
}

//有消息来时 闪动
private void ChatRoomMsg_TextChanged(object sender, EventArgs e)
{
this.timer1.Enabled = true;
}

      private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
        {
            if (this.timer1.Enabled)
            {
                this.timer1.Enabled = false;
            }
            if (e.Button == MouseButtons.Left && this.WindowState == FormWindowState.Minimized)
            {
                //判断是否已经最小化于托盘
                if (WindowState == FormWindowState.Minimized)
                {
                    this.StopRectTimer.Enabled = false;

                    StopDock = AnchorStyles.None;
                    //还原窗体显示
                    WindowState = FormWindowState.Normal;
                    //激活窗体并给予它焦点
                    //this.Activate();
                    //任务栏区显示图标
                    this.ShowInTaskbar = false;
                    //托盘区图标隐藏
