关于把WS_CHILD 窗口更改为 WS_POPUPWINDOW 窗口遇到的问题。

枫舞的季节 2003-04-08 09:12:22

问题这样：
我在程序中的Dialog 中嵌入一个子窗口，我需要在一定时候让这个子窗口移动，而且这个移动的范围要允许超出父窗口的范围，因此我就想到把这个窗口设置成为 WS_POPUP
类型的窗口，但是我在设置的时候发现这个窗口怎么也不能超出父窗口的范围移动。
但是我发现 DIALOG 类型的 POPUP 窗口是可以移动到父窗口的范围外去的，请各位大虾帮助！！！THANKS .

otherwise, pop-up windows are the same as overlapped windows of the WS_OVERLAPPE

MFC开发过程序所需的ModifyStyle(needDelStyle,needAddStyle,SWP_FRAMECHANGED); Sytel: WS_BORDER Creates a window that has a border. WS_CAPTION Creates a window that has a title bar (implies the WS_BORDER style). Cannot be used with the WS_DLGFRAME style. WS_CHILD Creates a child window. 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 you draw within the parent window. Used when you create the parent window. WS_CLIPSIBLINGS Clips child windows relative to each other; that is, when a particular child window receives a paint message, the WS_CLIPSIBLINGS style clips all other overlapped child windows out of the region of the child window to be updated. (If WS_CLIPSIBLINGS is not given and child windows overlap, when you draw within the client area of a child window, it is possible to draw within the client area of a neighboring child window.) For use with the WS_CHILD style only. WS_DISABLED Creates a window that is initially disabled. WS_DLGFRAME Creates a window with a double border but no title. WS_GROUP Specifies the first control of a group of controls in which the user can move from one control to the next with the arrow keys. All controls defined with the WS_GROUP style FALSE after the first control belong to the same group. The next control with the WS_GROUP style starts the next group (that is, one group ends where the next begins). 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 of maximum size. WS_MAXIMIZEBOX Creates a window that has a Maximize button. WS_MINIMIZE Creates a window that is initially minimized. For use with the WS_OVERLAPPED style only. WS_MINIMIZEBOX Creates a window that has a Minimize button. WS_OVERLAPPED Creates an overlapped window. An overlapped window usually has a caption a

VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
