久坐提醒桌面小程序

依赖库

.Net Framework 4.5
HandyControl 3.2

网上下的一些小程序，达不到自己想要的效果，要么就是功能复杂，于是选择了自己开发。
采用WPF 基于HandyControl 开发的小程序。

有2年不写WPF开发了，练练手
平时工作一坐就是半天，眼睛不怎么好了，干眼严重

说明

设置提醒时间，及休息时间

默认50分钟休息10分钟，按整点算（强迫症），如果工作不足10分钟，则将时间加到下一轮中。
取消整点勾选，从开始时计划

久坐提醒倒计时

开始后右下角有小球球，显示倒计时，像360那样的窗口悬停不知道怎么做，没继续研究

休息提醒倒计时

距休息10秒时，窗体会显示到最上层，同时字体颜色变为黄色

休息到计时

从网上找的护眼图片，可以照着练练，再起来走一走。

代码说明

设置界面、倒计时、休息界面，三个页面，通过 VmReminder 进行数据共享

主窗体设置

这是基本框架，参考Office设计，右上解可扩展【设置】、【帮助】功能，可用于其它项目
设置工作时长、休息时长，默认从整点开始计时（有强迫症）

MainWindow.xaml

private void BtnStart_OnClick(object sender, RoutedEventArgs e)
{
    _vm.IsHourly = chkHourly.IsChecked.HasValue && chkHourly.IsChecked.Value;
    _vm.WorkValue = (int)numWork.Value;
    _vm.BreakValue = (int)numBreak.Value;
    //开始后，调用倒计时窗体，并将倒计时窗体设为主窗体，否则点拖盘图标，会弹出设置窗体
    CountDown countDown = new CountDown();
    countDown.DataContext = this._vm;
    countDown.InitData();
    Application.Current.MainWindow = countDown;
    countDown.Show();
    this.Close();
}

工作到计时

窗口倒计时时，显示在窗口右下角，
CountDown.xml
托盘图标--放在这个窗体下的原因，是因为休息转工作时，避免托盘下会出现多个图标

<hc:NotifyIcon x:Name="NotifyIcon" Click="NotifyIconContextContent_OnClick"
               Text="久坐提醒"
               Visibility="Visible"
               Icon="/Application.ico">
    <hc:NotifyIcon.ContextMenu>
        <ContextMenu>
            <MenuItem Click="Settings_OnClick" Header="设置"/>
            <MenuItem Click="Exit_OnClick" Header="退出"/>
        </ContextMenu>
    </hc:NotifyIcon.ContextMenu>
    <hc:Interaction.Triggers>
        <hc:EventTrigger EventName="Click">
            <!--<hc:EventToCommand Command="hc:ControlCommands.PushMainWindow2Top"/>-->
        </hc:EventTrigger>
    </hc:Interaction.Triggers>
</hc:NotifyIcon>

WPF StringFormat="{}{0:0#}:{1:0#}" 显示倒计时，格式化，如果个位数时，前面补0

<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" >
    <TextBlock HorizontalAlignment="Center" Margin="5" Style="{StaticResource TextBlockLargeBold}" Foreground="White">
        <TextBlock.Text>
            <MultiBinding StringFormat="{}{0:0#}:{1:0#}">
                <Binding Path="CountDownWorkMinute" />
                <Binding Path="CountDownWorkSecond" />
            </MultiBinding>
        </TextBlock.Text>
    </TextBlock>
</StackPanel>

/// <summary>
/// 窗口显示在右下角
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void CountDown_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
    var desktopWorkingArea = System.Windows.SystemParameters.WorkArea;
    this.Left = desktopWorkingArea.Right - this.Width;
    this.Top = desktopWorkingArea.Bottom - this.Height;
}

通过定时器，工作实现倒计时功能

private void Timer_OnTick(object sender, EventArgs e)
{
    Remind();

    //倒计时时结束，弹出休息窗口
    if (_vm.CountDownWorkMinute == 0 && _vm.CountDownWorkSecond == 0)
    {
        _timer.Stop();
        NotifyIcon.Visibility = Visibility.Hidden;
        WorkBreak workBreak = new WorkBreak();
        Application.Current.MainWindow = workBreak;
        workBreak.DataContext = this._vm;
        workBreak.InitData();
        workBreak.ShowDialog();
        this.Close();
        return;
    }
    //如果分钟大于0，秒=0，那分-1，秒>0 秒-1
    if (_vm.CountDownWorkMinute > 0)
    {
        if (_vm.CountDownWorkSecond > 0)
        {
            _vm.CountDownWorkSecond--;
        }
        else
        {
            _vm.CountDownWorkMinute--;
            _vm.CountDownWorkSecond = 60;
        }
    }

    if (_vm.CountDownWorkMinute == 0)
    {
        _vm.CountDownWorkSecond--;
    }
}

休息倒计时

休息窗体显示两护眼张图片和一个休息到计时，按ESC时可取消本次休息，
