设置子窗口的文本颜色

我正在尝试更改静态控件的文本/背景颜色。我可以通过以下方式做到这一点：

// This is the 'main' window
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
hInst = hInstance;
HWND hWnd = CreateWindowW(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW &~WS_MAXIMIZEBOX | WS_CLIPCHILDREN | WS_CLIPSIBLINGS,
CW_USEDEFAULT, 0, 1035, 764, nullptr, nullptr, hInstance, nullptr);
...
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
case WM_CTLCOLORSTATIC:
{
MessageBox( NULL, "CTLCOLORSTATIC called", "", MB_OK );
HDC hdcStatic = (HDC)wParam;
SetTextColor(hdcStatic, RGB(200, 200, 20));
SetBkColor(hdcStatic, RGB(10, 10, 10));
return (INT_PTR)CreateSolidBrush(RGB(30, 30, 30));
}
default:
return DefWindowProc( hWnd, message, wParam, lParam );
}

但是，如果我将窗口放在另一个窗口中，则子控件文本/背景颜色将保持默认值：

// This is the 'parent' window, which resides in the 'main' window
HWND parent = CreateWindowEx
(
0,
_TEXT("STATIC"),
"",
WS_TABSTOP | WS_VISIBLE  | BS_SOLID | WS_CLIPCHILDREN,
10, 10, 500, 500,
hwnd,
NULL,
(HINSTANCE)GetWindowLong(hwnd, GWLP_HINSTANCE),
NULL
);
// This is the 'child' window which resides in the 'parent' window
HWND child = CreateWindowEx
(
0,
_TEXT("STATIC"),
"SubItem",
WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_SOLID,
10, 10, 100, 100,
parent,
NULL,
(HINSTANCE)GetWindowLong(parent, GWLP_HINSTANCE),
NULL
);

总而言之，我有 3 个窗口：

HWND hwnd;   // the 'main' application window (color changes fine)
HWND parent; // the 'parent/container' window which is inside the 'main' window (color changes fine)
HWND child;  // the 'child' window which is inside the 'parent' window (color DOES NOT change)      

即使我将 MessageBox 放在WM_CTLCOLORSTATIC中，我也会看到每次绘制子项时都会触发它，但颜色不会为子项更改，而只会为父项更改颜色。

据我了解，我需要在主窗口过程中处理消息，但我并不完全清楚如何做到这一点。 如果我将 (HWND)lParam 与子级 HWND 进行比较，它们是相同的(在默认开关情况下)，所以我可以在"默认"部分获得引用，但我不确定我应该如何从那里处理它。

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
case WM_CTLCOLORSTATIC:
{
if ((HWND)lParam == child )
MessageBox( NULL, "Reference Match for CTLCOLORSTATIC", "", MB_OK ); // <-- THIS NEVER TRIGGERS
}
....
default:
if ((HWND)lParam == child )
MessageBox( NULL, "Reference Match for DEFAULT", "", MB_OK ); // <-- THIS DOES TRIGGER
return DefWindowProc( hWnd, message, wParam, lParam );
}
return 0;
}

我将一个窗口放在另一个窗口中的原因是我可以在父窗口中使用WS_CLIPCHILDREN属性(以防子窗口移动/滚动)。
