PyQt获取系统文件图标

其实也就3行代码

fileInfo = Qt.QFileInfo(filename)

fileIcon = Qt.QFileIconProvider()

icon = QtGui.QIcon(fileIcon.icon(fileInfo))

下面是一个小例子：

 

   
   
   
   

    
    
    
    
    #

     fileInfo 
    
    
    
    =
    
    
    
     Qt.QFileInfo(filename) fileIcon

    =
    
    
    
     QtCore.QFileInfo(filename).fileName() 
    
    
    
    return
    
    
    
     icon,name 
    
    
    
    if

    ==
    
    
    
     
    
    
    
    '
    
    
    
    __main__
    
    
    
    '
    
    
    
    : 
    
    
    
    import
    
    
    
     sys app 
    
    
    
    =
    
    
    
     QtGui.QApplication(sys.argv) frm 
    
    
    
    =
    
    
    
     GetIconDemo() frm.show() sys.exit(app.exec_()) 运行效果如下：
