因为才学WINDOW API没多久，因此为题总是多的不的了，在这里我希望各位大侠成全后生一下。
请问WINDOW API中窗口类的风格与窗口风格以及SHOWWINDOW中的显示方式的联系与区别？希望各位大侠尽可能的详细帮小弟解答一下，我没法了，谢谢帮忙哈。

【深入浅出flink】第8篇：一篇文章搞懂flink window中的所有内容，保证你完全明白window的分类、window的组成以及window API Flink支持多种窗口类型，按照驱动类型分为：时间驱动的Time Window（如每30秒钟）和数据驱动的Count Window（如每100个事件）。按照窗口的滚动方式又可以分成：滚动窗口（Tumbling Window，无重叠），滑动窗口（Sliding Window，有重叠）和会话窗口（Session Window，活动间隙）。按照当前流有没有通过keyBy分区，分为Keyed Window和Non Keyed Window。另外，还有全局窗口（global windows）和自定义出窗口。阅读详情

不管怎么说，首先我还是要真心的感谢你，谢谢你的帮助。只不过因为我的英语水平有限，并且英语翻译器的水平也是很有限的，而对于一个像我这种才入门的后生来说，第一学术语言太多我搞不懂，第二翻译的程度不到位让我不好理解意思，因此还要麻烦各位高手，侠爷们细心的指导一下我这个后生了，对你们的帮助，我深感谢意，谢谢你们了，麻烦了哈。

Class Styles

The class styles define additional elements of the window class. Two or more styles can be combined by using the bitwise OR (|) operator. To assign a style to a window class, assign the style to the style member of the WNDCLASSEX structure. The class styles are as follows. 



Style Action 

CS_BYTEALIGNCLIENT Aligns the window's client area on a byte boundary (in the x direction). This style affects the width of the window and its horizontal placement on the display. 

CS_BYTEALIGNWINDOW Aligns the window on a byte boundary (in the x direction). This style affects the width of the window and its horizontal placement on the display. 

CS_CLASSDC Allocates one device context to be shared by all windows in the class. Because window classes are process specific, it is possible for multiple threads of an application to create a window of the same class. It is also possible for the threads to attempt to use the device context simultaneously. When this happens, the system allows only one thread to successfully finish its drawing operation.  

CS_DBLCLKS Sends a double-click message to the window procedure when the user double-clicks the mouse while the cursor is within a window belonging to the class.  

CS_DROPSHADOW Windows XP: Enables the drop shadow effect on a window. The effect is turned on and off through SPI_SETDROPSHADOW. Typically, this is enabled for small, short-lived windows such as menus to emphasize their Z order relationship to other windows. 

CS_GLOBALCLASS Specifies that the window class is an application global class. For more information, see Application Global Classes. 

CS_HREDRAW Redraws the entire window if a movement or size adjustment changes the width of the client area. 

CS_NOCLOSE Disables Close on the window menu. 

CS_OWNDC Allocates a unique device context for each window in the class.  

CS_PARENTDC Sets the clipping rectangle of the child window to that of the parent window so that the child can draw on the parent. A window with the CS_PARENTDC style bit receives a regular device context from the system's cache of device contexts. It does not give the child the parent's device context or device context settings. Specifying CS_PARENTDC enhances an application's performance.  

CS_SAVEBITS Saves, as a bitmap, the portion of the screen image obscured by a window of this class. When the window is removed, the system uses the saved bitmap to restore the screen image, including other windows that were obscured. Therefore, the system does not send WM_PAINT messages to windows that were obscured if the memory used by the bitmap has not been discarded and if other screen actions have not invalidated the stored image. 

This style is useful for small windows (for example, menus or dialog boxes) that are displayed briefly and then removed before other screen activity takes place. This style increases the time required to display the window, because the system must first allocate memory to store the bitmap.

 

CS_VREDRAW Redraws the entire window if a movement or size adjustment changes the height of the client area.



Window Styles 



--------------------------------------------------------------------------------



The following styles can be specified wherever a window style is required. After the control has been created, these styles cannot be modified, except as noted. 



Constants



WS_BORDER 

Creates a window that has a thin-line border.



WS_CAPTION 

Creates a window that has a title bar (includes the WS_BORDER style).



WS_CHILD 

Creates a child window. A window with this style cannot have a menu bar. This style cannot be used with the WS_POPUP style.



WS_CHILDWINDOW 

Same as the WS_CHILD style.



WS_CLIPCHILDREN 

Excludes the area occupied by child windows when drawing occurs within the parent window. This style is used when creating the parent window.



WS_CLIPSIBLINGS 

Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window.



WS_DISABLED 

Creates a window that is initially disabled. A disabled window cannot receive input from the user. To change this after a window has been created, use EnableWindow. 



WS_DLGFRAME 

Creates a window that has a border of a style typically used with dialog boxes. A window with this style cannot have a title bar.



WS_GROUP 

Specifies the first control of a group of controls. The group consists of this first control and all controls defined after it, up to the next control with the WS_GROUP style. The first control in each group usually has the WS_TABSTOP style so that the user can move from group to group. The user can subsequently change the keyboard focus from one control in the group to the next control in the group by using the direction keys.

You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use SetWindowLong.





WS_HSCROLL 

Creates a window that has a horizontal scroll bar.



WS_ICONIC 

Creates a window that is initially minimized. Same as the WS_MINIMIZE style.



WS_MAXIMIZE 

Creates a window that is initially maximized.



WS_MAXIMIZEBOX 

Creates a window that has a maximize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. 



WS_MINIMIZE 

Creates a window that is initially minimized. Same as the WS_ICONIC style.



WS_MINIMIZEBOX 

Creates a window that has a minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. 



WS_OVERLAPPED 

Creates an overlapped window. An overlapped window has a title bar and a border. Same as the WS_TILED style.



WS_OVERLAPPEDWINDOW 

Creates an overlapped window with the WS_OVERLAPPED, WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX, and WS_MAXIMIZEBOX styles. Same as the WS_TILEDWINDOW style. 



WS_POPUP 

Creates a pop-up window. This style cannot be used with the WS_CHILD style.



WS_POPUPWINDOW 

Creates a pop-up window with WS_BORDER, WS_POPUP, and WS_SYSMENU styles. The WS_CAPTION and WS_POPUPWINDOW styles must be combined to make the window menu visible.



WS_SIZEBOX 

Creates a window that has a sizing border. Same as the WS_THICKFRAME style.



WS_SYSMENU 

Creates a window that has a window menu on its title bar. The WS_CAPTION style must also be specified.



WS_TABSTOP 

Specifies a control that can receive the keyboard focus when the user presses the TAB key. Pressing the TAB key changes the keyboard focus to the next control with the WS_TABSTOP style. 

You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use SetWindowLong.





WS_THICKFRAME 

Creates a window that has a sizing border. Same as the WS_SIZEBOX style.



WS_TILED 

Creates an overlapped window. An overlapped window has a title bar and a border. Same as the WS_OVERLAPPED style. 



WS_TILEDWINDOW 

Creates an overlapped window with the WS_OVERLAPPED, WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX, and WS_MAXIMIZEBOX styles. Same as the WS_OVERLAPPEDWINDOW style. 



WS_VISIBLE 

Creates a window that is initially visible.

This style can be turned on and off by using ShowWindow or SetWindowPos.





WS_VSCROLL 

Creates a window that has a vertical scroll bar.
