定时任务 Wpf.Quartz.Demo.4

本文继续介绍定时任务 Wpf.Quartz.Demo.3的一些小细节， 代码也请前往第3节下载。

1.RichTextBox右键菜单

 <RichTextBox.ContextMenu>
                <ContextMenu>
                    <MenuItem Header="剪贴" Command="ApplicationCommands.Cut"/>                     
                    <MenuItem Header="复制" Command="ApplicationCommands.Copy"/>                                         
                    <MenuItem Header="粘贴" Command="ApplicationCommands.Paste"/>                                          
                    <MenuItem Header="清除" Click="MenuItemClear_Click"/>   
                    <MenuItem x:Name="menuPause" Header="暂停" Click="MenuItemPause_Click"/>   
                </ContextMenu>
            </RichTextBox.ContextMenu>

其中上面上个是系统默认的，自己要添加，可以自己定义。

2.右键DataGrid,选中该行。

 <i:Interaction.Triggers>
                <i:EventTrigger EventName="PreviewMouseRightButtonDown">
                    <local:ExInvokeCommandAction Command="{Binding PreviewMouseRightComamnd}" CommandParameter="{Binding SelectedItem, ElementName=table}"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>

private void PreviewMouseRight(object para)
        {
            RoutedEventArgs e = ((ExCommandParameter)para).EventArgs as RoutedEventArgs;
            var treeViewItem = VisualUpwardSearch<UIElement>(e.OriginalSource as DependencyObject) as UIElement;

            if (treeViewItem == null) return;
            treeViewItem.Focus();
            e.Handled = true;
        }

        private static DependencyObject VisualUpwardSearch<M>(DependencyObject source)
        {
            while (source != null && source.GetType() != typeof(M))
            {
                if (source is Visual || source is Visual3D)
                    source = VisualTreeHelper.GetParent(source);
                else
                    source = LogicalTreeHelper.GetParent(source);
            }
            return source;
        }

3.任务的基本接口，主要是系统的启动，停止等命令

public interface IRun:IBaseRunner
    {
        [Newtonsoft.Json.JsonIgnore()]
        Action<string, LogLevel> LogOut { get; set; }

        Task Start();

        Task Stop();

        Task ReStart();

        Task Resume();

        Task Pause();

        Task RunNowOneTime();
    }

4.任务的设置的接口，主要是任务的配置保存。

 public interface IBaseRunner
    {
        string Name { get; }
        string DisplayName { get; set; }
        string Remark { get; set; }
        string CronExpression { get; set; }
        TriggerState TriggerState { get; set; }
        string SettingStr { get; set; }
        DateTime? NextRunTime { get; }
        DateTime[] NextRunTimes { get; set; }
        DateTime? StartTime { get; set; }
        DateTime? EndTime { get; set; }
        bool IsEdit { get; set; }
        CronSecondSet CronSecondSet { get; set; }
        CronMinuteSet CronMinuteSet { get; set; }
        CronHourSet CronHourSet { get; set; }
        CronDaySet CronDaySet { get; set; }
        CronMonthSet CronMonthSet { get; set; }
        CronWeekSet CronWeekSet { get; set; }
        CronYearSet CronYearSet { get; set; }
        EasyCronSet EasyCronSet { get; set; }
        Mode Mode { get; set; }
        void Info(string message);
        void DEBUG(string message);
        void ERROR(string message);
        void FATAL(string message);
        void WARN(string message);

    }

5.任务类，接口IRun的实现。

6.BaseRunner，主要是设置Cron

具体的请自行查看对应的类。

        public CronSecondSet CronSecondSet { get; set; } = new CronSecondSet();
        public CronMinuteSet CronMinuteSet { get; set; } = new CronMinuteSet();
        public CronHourSet CronHourSet { get; set; } = new CronHourSet();
        public CronDaySet CronDaySet { get; set; } = new CronDaySet();
        public CronMonthSet CronMonthSet { get; set; } = new CronMonthSet();
        public CronWeekSet CronWeekSet { get; set; } = new CronWeekSet();
        public CronYearSet CronYearSet { get; set; } = new CronYearSet();

        public EasyCronSet EasyCronSet { get; set; } = new EasyCronSet();

主要代码就是用户自定义设置，大家运行程序看效果。

另外，这种设置太专业了，不适合用户使用，因此设计了用户常用的模式。

是不是简单友好多了。

至此完结。

下次打算写一个wcf的Demo，当自己学习的动力。
