簡介
Microsoft官網(wǎng)關(guān)于 WindowChome 的介紹
截取Microsoft文章的一段話：
??若要在保留其標(biāo)準(zhǔn)功能時(shí)自定義窗口，可以使用該WindowChrome類。 該WindowChrome類將窗口框架的功能與視覺對象分開，并允許你控制應(yīng)用程序窗口的客戶端和非客戶端區(qū)域之間的邊界。 通過WindowChrome該類，可以通過擴(kuò)展工作區(qū)來覆蓋非工作區(qū)，將 WPF 內(nèi)容置于窗口框架中。 同時(shí)，它通過兩個(gè)不可見區(qū)域保留系統(tǒng)行為： 調(diào)整邊框 和 標(biāo)題 區(qū)域的大小。

布局實(shí)現(xiàn)
首先我們需要在
MainWindow也就是我們的主窗口中的Window.Resources中實(shí)現(xiàn)WindowChrome的基本樣式：WindowChrome.ResizeBorderThickness設(shè)置不可見邊框?qū)挾?br>WindowChrome.CaptionHeight>設(shè)置屬于標(biāo)題欄的范圍——高度WindowChrome.UseAeroCaptionButtons是否啟用默認(rèn)系統(tǒng)按鈕功能——三大金剛鍵WindowChrome.NonClientFrameEdges設(shè)置客戶區(qū)域，使用bottom可以實(shí)現(xiàn)加載時(shí)空白窗口而不顯示默認(rèn)窗口，提升用戶體驗(yàn)

重寫窗口，實(shí)現(xiàn)最大化窗口下，標(biāo)題欄及客戶區(qū)域偏移問題的修正。
通過代碼獲取當(dāng)前窗口的工作區(qū)域，及任務(wù)欄以外的其他區(qū)域System.Windows.SystemParameters.WorkArea.Width獲取工作區(qū)域的寬System.Windows.SystemParameters.WorkArea.Height獲取工作區(qū)域的高
為什么要使用ValueConverter主要是因?yàn)?WorkArea返回的類型無法直接 binding xaml文章來源：http://www.zghlxwxcb.cn/news/detail-457965.html

結(jié)語
一開始，確實(shí)很難搞，Microsoft 的文檔，里面也并沒有，詳細(xì)介紹窗口內(nèi)容溢出的問題，但是只要仔細(xì)研究過 WPF 的同學(xué)都知道，很多東西是可以通過
Trigger來實(shí)現(xiàn)的。Get 到這一點(diǎn)很多問題就迎刃而解了。歡迎大家留言通過探討 ??????文章來源地址http://www.zghlxwxcb.cn/news/detail-457965.html
