框架使用 大于等于.NET40打开网页闪烁 。

Visual Studio 2022打开网页闪烁 。

项目使用 MIT开源许可协议打开网页闪烁 。

接着上一篇 基础托盘打开网页闪烁 。

新增如下：

增加属性 TwinkInterval托盘图标闪烁间隔默认 500ms， IsTwink = true 开启闪烁打开网页闪烁 。

设计器时不显示托盘打开网页闪烁 。

Nuget 最新[1] Install-Package WPFDevelopers 1.0.9.2-preview

Nuget 最新[2] Install-Package WPFDevelopers..Minimal 3.2.8.2-preview

1）托盘闪烁代码如下：

///<summary>

///托盘图标闪烁间隔

///</summary>

publicstaticreadonlyDependencyProperty TwinkIntervalProperty =

DependencyProperty.Register( "TwinkInterval",

typeof(TimeSpan), typeof(NotifyIcon), newPropertyMetadata(TimeSpan.FromMilliseconds( 500), OnTwinkIntervalChanged));

///<summary>

///托盘图标是否开启闪烁

///</summary>

publicstaticreadonlyDependencyProperty IsTwinkProperty =

DependencyProperty.Register( "IsTwink",

typeof( bool), typeof(NotifyIcon), newPropertyMetadata( false, OnIsTwinkChanged));

privatestaticvoidOnIsTwinkChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

if(d isNotifyIcon trayService)

varnotifyIcon = (NotifyIcon)d;

if(notifyIcon.Visibility != Visibility.Visible) return;

if(( bool)e.NewValue)

if(notifyIcon._dispatcherTimerTwink == null)

notifyIcon._dispatcherTimerTwink = newDispatcherTimer

Interval = notifyIcon.TwinkInterval

notifyIcon._dispatcherTimerTwink.Tick += notifyIcon.DispatcherTimerTwinkTick;

notifyIcon._tempIconHandle = notifyIcon._hIcon;

notifyIcon._dispatcherTimerTwink.Start;

else

notifyIcon._dispatcherTimerTwink?.Stop;

notifyIcon._dispatcherTimerTwink.Tick -= notifyIcon.DispatcherTimerTwinkTick;

notifyIcon._dispatcherTimerTwink = null;

notifyIcon._iconHandle = notifyIcon._tempIconHandle;

notifyIcon.ChangeIcon( false, notifyIcon._iconHandle);

notifyIcon._tempIconHandle = IntPtr.Zero;

privatestaticvoidOnTwinkIntervalChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

if(d isNotifyIcon trayService)

varnotifyIcon = (NotifyIcon)d;

notifyIcon._dispatcherTimerTwink.Interval = (TimeSpan)e.NewValue;

2）设计器时不显示托盘代码如下：

if(DesignerHelper.IsInDesignMode == true) returnfalse;

#region是否设计时模式

publicclassDesignerHelper

privatestaticbool? _isInDesignMode;

publicstaticboolIsInDesignMode

get

if(!_isInDesignMode.HasValue)

_isInDesignMode = ( bool)DependencyPropertyDeor.FromProperty(DesignerProperties.IsInDesignModeProperty,

typeof(FrameworkElement)).Metadata.DefaultValue;

return_isInDesignMode.Value;

#endregion

3）使用托盘代码如下：

<wpfdev:NotifyIconTitle="WPF开发者"Name="WpfNotifyIcon">

<wpfdev:NotifyIcon.ContextMenu>

<ContextMenu>

<MenuItemHeader="托盘消息"Click="SendMessage_Click"/>

<MenuItemHeader="闪烁"Name="menuItemTwink"Click="Twink_Click"/>

<MenuItemHeader="关于"Click="About_Click">

<MenuItem.Icon>

<PathData="{StaticResource PathWarning}"

Fill="{DynamicResource PrimaryNormalSolidColorBrush}"

Stretch="Uniform"Height="20"Width="20"/>

</MenuItem.Icon>

</MenuItem>

<MenuItemHeader="退出"Click="Quit_Click"/>

</ContextMenu>

</wpfdev:NotifyIcon.ContextMenu>

</wpfdev:NotifyIcon>

4）事件Twink_Click代码如下：

privatevoidTwink_Click(objectsender, RoutedEventArgs e)

WpfNotifyIcon.IsTwink = !WpfNotifyIcon.IsTwink;

menuItemTwink.IsChecked = WpfNotifyIcon.IsTwink;
