在項(xiàng)目開(kāi)發(fā)中的窗體的設(shè)計(jì)會(huì)影響用戶對(duì)軟件的整體印象，因此窗體的效果要設(shè)計(jì)得美觀一些。

在對(duì)桌面進(jìn)行操作時(shí)，為了使桌面更加美觀，可以在桌面的上面加一層類似于玻璃的效果，用戶可以用鼠標(biāo)透過(guò)“玻璃”對(duì)桌面進(jìn)行操作。本實(shí)例通過(guò)使用鼠標(biāo)穿透窗體類實(shí)現(xiàn)以上功能。主要用到了 API 函數(shù) SetWindowLong 和 GetWindowLong。

1.創(chuàng)建一個(gè)項(xiàng)目，默認(rèn)窗體為 Form1，將該窗體的 FormBordeStyle 屬性設(shè)置為 None，BackColor 屬性設(shè)置為 Gainsboro，Opacity 屬性設(shè)置為 60%，WindowState 屬性設(shè)置為 Maximized。

2.在 Form1 窗體中添加一個(gè) NotifyIcon 控件，并設(shè)置其 Icon 屬性為指定的圖標(biāo)，顯示提示信息；添加一個(gè) ContextMenuStrip 控件，作為程序的快捷菜單。

030 窗體換膚程序

本實(shí)例的基本原理是給窗體的各個(gè)組成部分更換圖片，基于該原理，首先需要分析窗體的組成部分，主要包括標(biāo)題欄、左邊框、右邊框、下邊框、窗體中間區(qū)域及可能存在的菜單欄，其中標(biāo)題欄和3個(gè)邊框無(wú)法通過(guò)設(shè)置相關(guān)屬性來(lái)達(dá)到更換背景圖片的目的。對(duì)于這個(gè)問(wèn)題，可以通過(guò)取消窗體的 FormBorderStyle 屬性，同時(shí)在標(biāo)題欄和3個(gè)邊框的位置添加 Panel 控件來(lái)解決，然后通過(guò)選擇不同的皮膚類型，為窗體的各個(gè)組成部分設(shè)置圖片，最終達(dá)到窗體換膚的效果。在以上過(guò)程中，最主要的技術(shù)問(wèn)題是如何從指定的文件創(chuàng)建 Image 對(duì)象，以及如何獲取圖片的路徑。

1.創(chuàng)建一個(gè)項(xiàng)目，默認(rèn)窗體為 Form1，設(shè)置 Form1 的 AutoscaleMode 屬性為 Inherit，DoubleBuffered 屬性為 True，IsMdiContainer 屬性為 True。

2.在窗體中添加6個(gè) Panel 控件，分別用來(lái)作為窗體的標(biāo)題欄、下邊框、左邊框、右邊框、左下角邊框和右下角邊框；添加一個(gè) ContextMenuStrip 控件，用來(lái)作為更換皮膚的快捷菜單；添加3個(gè) PictureBox 控件，分別用來(lái)顯示最大化、最小化和關(guān)閉圖片。
