## QQuickView ##

官方描述：  
The QQuickView class provides a window for displaying a Qt Quick user interface.

This is a convenience subclass of QQuickWindow which will automatically load and display a QML scene when given the URL of the main source file. Alternatively, you can instantiate your own objects using QQmlComponent and place them in a manually setup QQuickWindow.

默认的qquickview产生的窗口是这样的：

所以就需要我们设置点什么了。

但是突然发现，怎么折腾没啥用。

后来，索性设置为dialog吧！

但是单词的dialog还是有问题，会出现一个万恶的？(帮助)按钮。

## 设置flags ##

**设置Dialog**  
Qt::Dialog:  
Indicates that the widget is a window that should be decorated as a dialog (i.e., typically no maximize or minimize buttons in the title bar). This is the default type for QDialog. If you want to use it as a modal dialog, it should be launched from another window, or have a parent and used with the QWidget::windowModality property. If you make it modal, the dialog will prevent other top-level windows in the application from getting any input. We refer to a top-level window that has a parent as a secondary window.

**固定大小**  
Qt::MSWindowsFixedSizeDialogHint:  
Gives the window a thin dialog border on Windows. This style is traditionally used for fixed-size dialogs.

**带工具栏**  
Qt::WindowTitleHint:  
Gives the window a title bar.

**关闭默认的window title**  
Qt::CustomizeWindowHint:  
Turns off the default window title hints.

**有一个关闭按钮**  
Qt::WindowCloseButtonHint:  
Adds a close button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.

稳妥：
