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。由於WPF自帶的進度條其實不怎麼好看,而且沒啥視覺效果。後來,裝VS2012時,發現安裝過程中進度條效果不錯,於是上網查了資料。學習了ModernUI(開源的),地址:https://github.com/firstfloorsoftware/mui。
後來,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、實現說明
1、下載MUI相關代碼或者dll文件;
2、工程中引入該dll,並引入其資源文件;
復制代碼 代碼如下:
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);
復制代碼 代碼如下:
4、後台實現,由於要根據情況更新進度文字及進度條的值。所以,這裡用到了異步BackgroundWorker(具體可以網上查查相關資料);
