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?

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).

Solution 2

The code below would work. And please explain yourself.

C++

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);
