仿vs实现WPF好看的进度条

来源:互联网 作者:脚本宝典 时间:2015-06-11 13:25 【

由于WPF自带的进度条其实不怎么好看,而且没啥视觉效果。下面给大家分享的是仿VS的进度条效果的代码,有需要的小伙伴可以参考下。

为了界面友好,一般的操作时间较长时,都需要增加进度条提示。由于WPF自带的进度条其实不怎么好看,而且没啥视觉效果。后来,装VS2012时,发现安装过程中进度条效果不错,于是上网查了资料。学习了ModernUI(开源的),地址:https://github.com/firstfloorsoftware/mui

  后来,做了尝试写了个Demo,效果不错。另外,专门录制了tif文件,方便大家看到效果。废话不多说,先展示效果:

一、效果展示

  A、VS2012安装界面图;

  B、个人尝试Demo效果图: 

二、实现说明

  1、下载MUI相关代码或者dll文件;

  2、工程中引入该dll,并引入其资源文件;

 

复制代码代码如下:

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.xaml" />
                <ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.Light.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

 

  3、在需要显示进度条的页面,加入控件(其实还是WPF控件,只是MUI扩展了其样式而已);

 

复制代码代码如下:

<Label Margin="280,169,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblMainState" HorizontalAlignment="Left" VerticalAlignment="Top">正在启动:</Label>
        <ProgressBar Margin="280,200,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Width="500" Minimum="0" x:Name="ProgressControlRealValue" Maximum="1"  Value="0.1" Height="16" IsIndeterminate="False"/>
        <Label Margin="280,212,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblProcess" HorizontalAlignment="Left" VerticalAlignment="Top">正在加载地图数据...</Label>
        <ProgressBar Margin="280,250,0,0" HorizontalAlignment="Left" VerticalAlignment="Top"  Minimum="0" x:Name="ProgressControl"  Width="500" Maximum="2" Height="16" IsIndeterminate="True" />

 

  4、后台实现,由于要根据情况更新进度文字及进度条的值。所以,这里用到了异步BackgroundWorker(具体可以网上查查相关资料);
