Qt4怎樣設定應用程式的表徵圖-windows平台

，通過搜尋Qt Assistant，發現有如下說明：

Setting the Application Icon on Windows

First, create an ICO format bitmap file that contains the icon image. This can be done with e.g. Microsoft Visual C++: Select File|New, then select the File tab in the dialog that appears, and choose Icon. (Note that you do not need to load your application into Visual C++; here we are only using the icon editor.)

Store the ICO file in your application's source code directory, for example, with the name myappico.ico. Then, create a text file called, say, myapp.rc in which you put a single line of text:

 IDI_ICON1               ICON    DISCARDABLE     "myappico.ico"Finally, assuming you are using qmake to generate your makefiles, add this line to your myapp.pro file:

 RC_FILE = myapp.rcRegenerate your makefile and your application. The .exe file will now be represented with your icon in Explorer.

If you do not use qmake, the necessary steps are: first, run the rc program on the .rc file, then link your application with the resulting .res file.

那麼做法就清楚了：

第一步，準備個ICO表徵圖。

例如：myApp.ico 用任何的文字編輯器建立個檔案

裡面寫上一行：
IDI_ICON1           ICON DISCARDABLE "myApp.ico"
 

第二步，儲存改名為 myApp.rc並把它和你的表徵圖myApp.ico一起放置到你的Qt工程的目錄裡面。

第三步，用文字編輯器開啟你的Qt工程檔案（如 myApp.pro ），在裡面的最後面新添一行：
RC_FILE = myApp.rc 

第四步，在程式中添加如下代碼：

//app是程式中唯一的QApplication對象

app.setWindowIcon(QIcon("myApp.ico")); 

注意：如果你的myApp.rc和你的表徵圖myApp.ico不是在你的Qt工程目錄裡面，那麼最後一句的代碼中請指明表徵圖檔案的路徑。
