介绍 本文提供了一个popup-less通知窗口,并节省了用户从“Click-on-the-OK-button-to-continue”的痛苦。 背景 当使用Microsoft Outlook,你遇到一个邮件通知窗口慢慢出现,消失了。但是,当你把鼠标在窗口,它变得不透明,然后再次鼠标,它消失了,这个过程仍在继续。所以,最终,它逐渐消退或你忽略了窗口,或者你关闭它或者你点击它阅读邮件。本文描述了如何使用c#构建这样的一个窗口。 的逻辑 下面是步骤: 最初使透明度级别0。显示窗口。开始显示定时器T1。逐步提高透明度的T1,直到达到最大水平1.0。停止定时器T1。启动隐藏计时器T2。降低不透明度水平T2,直到达到的最低水平0.01。停止计时器T2。干净的消息。关闭窗口。 使用的代码 基本类,实现了逻辑是KNotifio。 隐藏通知窗口计时器 隐藏的计时器事件如下: 隐藏,复制Code

privatevoid tmrHide_Tick(object sender, EventArgs e)
{
   //Decrease the opacity level until its greater than zero
   if (this.Opacity > 0.00)
   {
      this.Opacity -= 0.01;
   }
   else
   {
      //Window has gone completely transparent
      tmrHide.Stop();    //Stop the timer
      CloseWnd();        //Close window
   }
}

显示通知窗口计时器 显示计时器事件如下: 隐藏,复制Code

private void tmrShow_Tick(object sender, EventArgs e)
{
   //Increase opacity until it reaches maximum
   if (this.Opacity < 0.99)
   {
      this.Opacity += 0.01;
   }
   else
   {
      //Window already opaque
      tmrShow.Stop();     //Let's stop the timer

      tmrHide.Start();    //Start hiding the window
   }
}

关闭通知窗口 下面是如何关闭窗口: 隐藏,复制Code

private void CloseWnd()
{
   try
   {
      //Stop timers
      g_Fio.tmrHide.Stop();
      g_Fio.tmrShow.Stop();

      g_Fio.Close();                          //Close the form
      m_strPreviousMessage = string.Empty;    //Clean message
   }
   catch (Exception exec) { }
}

窗口如何显示 隐藏,复制Code

public static void Show(string strMessage, i nShowTime, int nHideTime)
{
   //Set the time it should take to show the window
   m_nShowTime = nShowTime - 5;
   //Set the time it would take to hide the window
   m_nHideTime = nHideTime;
   Show(strMessage);
}

Show()方法 隐藏,复制Code

public static void Show(string strMessage)
{
   try
   {
      if (m_strPreviousMessage == strMessage)
         return;
      else
         m_strPreviousMessage = strMessage;
         KNotifio theNotifio = new KNotifio();
         g_Fio = theNotifio;
         theNotifio.txtMessage.Text = strMessage;
         theNotifio.Show();
         theNotifio.panel1.Focus();
   }
   catch (Exception exc)
   {
      ;
   }
}

构造函数初始化/ 隐藏,复制Code

public KNotifio()
{
   InitializeComponent();
   tmrHide.Interval = m_nHideTime;    //Set timers
   tmrShow.Interval = m_nShowTime;

   try
   {
      //Set round rects
   } catch (Exception exc) { }

   //Move window close to system tray (above the clock)
   Location = new Point(Screen.PrimaryScreen.Bounds.Width -
      this.Width, Screen.PrimaryScreen.Bounds.Height -
      this.Height - 50);
}

圆角 我们称之为一个API圆的角落。 隐藏,复制Code

/// <spanclass="code-SummaryComment"><summary></span>
/// Provides MS Outlook styled dynamic notification window
/// <spanclass="code-SummaryComment"></summary></span>
public partial class KNotifio : Form
{
   //Need to make our window a bit rounded.
   [DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
   private static extern IntPtr CreateRoundRectRgn
   (
      int nLeftRect,        // x-coordinate of upper-left corner
      int nTopRect,         // y-coordinate of upper-left corner
      int nRightRect,       // x-coordinate of lower-right corner
      int nBottomRect,      // y-coordinate of lower-right corner
      int nWidthEllipse,    // height of ellipse
      int nHeightEllipse    // width of ellipse
   );
....

的兴趣点 用户可以设置特定的窗口动画。同样的,例如,消息类型是至关重要的信息,和盒子可以眨眼,等等。控制可以使更多的动画,用户集中,我们只需要设置AnimationTypes。警告标签。 本文转载于：http://www.diyabc.com/frontweb/news7275.html
