為了界面友好,一般的操作時間較長時,都需要增加進度條提示。由于WPF自帶的進度條其實不怎么好看,而且沒啥視覺效果。后來,裝VS2012時,發(fā)現(xiàn)安裝過程中進度條效果不錯,于是上網(wǎng)查了資料。學(xué)習(xí)了ModernUI(開源的),地址:https://github.com/firstfloorsoftware/mui。
后來,做了嘗試寫了個Demo,效果不錯。另外,專門錄制了tif文件,方便大家看到效果。廢話不多說,先展示效果:
一、效果展示
A、VS2012安裝界面圖;
B、個人嘗試Demo效果圖:
二、實現(xiàn)說明
1、下載MUI相關(guān)代碼或者dll文件;
2、工程中引入該dll,并引入其資源文件;
復(fù)制代碼 代碼如下:
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、在需要顯示進度條的頁面,加入控件(其實還是WPF控件,只是MUI擴展了其樣式而已);
復(fù)制代碼 代碼如下:
Label Margin="280,169,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblMainState" HorizontalAlignment="Left" VerticalAlignment="Top">正在啟動:/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">正在加載地圖數(shù)據(jù).../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、后臺實現(xiàn),由于要根據(jù)情況更新進度文字及進度條的值。所以,這里用到了異步BackgroundWorker(具體可以網(wǎng)上查查相關(guān)資料);
