问题描述

是否有用于确定窗口的小条和窗口边框大小的功能？



有充分理由我正在创建某种模态对话框拆分两个窗格，但是我很难计算每个窗格的坐标。



我使用了GetClientRect和GetWindowRect，但由于标题栏更宽比边界。



那么，这些函数是否存在？

解决方案

这是的一部分系统指标。应用程序不会决定它们是什么，它们是系统范围的。请参阅： http://msdn.microsoft.com /en-us/library/system.windows.systemparameters%28v=vs.110%29.aspx [ ^ ]。



如果你想为一个应用程序改变它，解决方案可能是：定义一个没有任何非客户区域的windows类，并在客户区模拟这些区域，或者只使用函数<设置单个窗口的样式 SetWindowLong ：

你需要使用索引 GWL_STYLE 并设置没有标题栏的样式（ WS_CAPTION ）且没有任何边框或框架（请参阅样式值的其他位）。

下面的代码可行。请自己解释一下。

 RECT rc1，rc2; 
  int  barWidth，titlebarHeight; 
  wchar_t  a [ 10 ]; 
 GetClientRect（hWnd，& rc1）; 
 GetWindowRect（hWnd，& rc2）; 
 barWidth =（（rc2.right-rc2.left） - （rc1.right-rc1.left））/ 2; 
 titlebarHeight =（rc2.bottom-rc2.top） - （rc1.bottom-rc1.top）-bar_width-GetSystemMetrics（SM_CYMENU）; 
 wsprintf（a，L  ％d，titlebarHeight）; 
 MessageBox（hWnd，a，L  无论，MB_OK）; 

Are there a functions for determining the size of a window's tittle bar and a windows border?

For good reasons I am creating some kind of Modal dialogue boxes with split two panes, however I am facing difficulty calculation the coordinates of each pane.

I used GetClientRect and GetWindowRect but there is a slight shift because the title bar is much wider than the border.

So, does such functions exist?

解决方案

This is a part of "system metrics". The application does not decide what are they, they are system-wide. Please see: http://msdn.microsoft.com/en-us/library/system.windows.systemparameters%28v=vs.110%29.aspx[^].

If you want to change it for a single application, the solution could be: define a windows class without any non-client areas at all, and simulate these areas in a client area, or just set the style for a single window using the function SetWindowLong:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633591%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms632600%28v=vs.85%29.aspx[^].

You would need to use the index GWL_STYLE and set style without a title bar (WS_CAPTION) and without any borders or frames (see other bits of the style value).

The code below would work. And please explain yourself.

RECT rc1, rc2;
int barWidth, titlebarHeight;
wchar_t a[10];
GetClientRect(hWnd, &rc1);
GetWindowRect(hWnd, &rc2);
barWidth=((rc2.right-rc2.left)-(rc1.right-rc1.left))/2;
titlebarHeight=(rc2.bottom-rc2.top)-(rc1.bottom-rc1.top)-bar_width-GetSystemMetrics(SM_CYMENU);
wsprintf(a, L"%d",  titlebarHeight);
MessageBox(hWnd, a, L"Whatever", MB_OK);
