推荐答案
不要忘了QScrollArea，这是基类，而QListView包含另一个控件，它被称为视口。它可以通过视（）方法accesed。
Don't forget that QScrollArea, which is base class for QListView contains "another" widget which is called Viewport. It can be accesed via viewport() method.
要实现透明你可以简单地只要致电：
To achieve transparency You can simply just call:
viewport()->setAutoFillBackground( false );和取决于其他设置（即父窗口小部件设置）你应该可以看到背景。
and depending on other setting (i.e. parent widget settings) You should see background.
