使图标闪烁WPF应用程序 [英] Make an icon blink wpf application

问题描述

我有一个图标.

 imgstop.Visibility = System.Windows.Visibility.Visible;

如何使图标显示为闪烁?

How can I make the icon to be appear to be blinking ?

我尝试了以下代码:

  public void blinkIconStopHide()
        {
            blinkTimerStop.Enabled = true;
            blinkTimerStop.Interval = 15000;
             imgstop.Visibility = System.Windows.Visibility.Hidden;
             blinkTimerStop.Elapsed += new System.Timers.ElapsedEventHandler(tick_to_hideStop);  
        }
        private void tick_to_hideStop(object sender, EventArgs e)
        {
            blinkIconStopShow();
        }  
        public void blinkIconStopShow()
        {
            blinkTimerStop.Enabled = true;
            blinkTimerStop.Interval = 15000;
            imgstop.Visibility = System.Windows.Visibility.Visible;
            blinkTimerStop.Elapsed += new System.Timers.ElapsedEventHandler(tick_to_showStop);   
        }
        private void tick_to_showStop(object sender, EventArgs e)
        {
            blinkIconStopHide();
        }  

但是屏幕上似乎没有任何闪烁.

But nothing seems to be blinking on the screen.

推荐答案

以下代码将通过切换可见性使您的Icon每秒闪烁一次.通过更改DispatcherTimer的时间间隔，您可以更快或更慢地闪烁图标.

The following code will let your Icon blink each second by toggeling visibility. By changing the Interval of the DispatcherTimer you can blink the icon faster or slower.

DispatcherTime _blinkTimer = new DispatcherTimer();

public void StartBlinking() {
  _blinkTimer.Interval = TimeSpan.FromSeconds(1);
  _blinkTimer.Elapsed += ToggleIconVisibility;
  _blinkTimer.Start();
}

public void StopBlinking() {
  _blinkTimer.Stop();
  _blinkTimer.Elapsed -= ToggleIconVisibility;
}

private void ToggleIconVisibility(object sender, EventArgs e)
{
  imgstop.Visibility = !imgstop.Visibility;
}
