未解决 [求助]WM_MOUSEMOVE和CreateWindow坐标偏差.

写自绘的时候需要用到鼠标坐标.结果坐标偏差很大.
使用的是WM_MOUSEMOVE 取鼠标坐标点.
MousePoint.x = GET_X_LPARAM(lParam);
MousePoint.y = GET_Y_LPARAM(lParam);
测试发现左上0,0开始越往右下角,坐标偏差值越大.
然后就是CreateWindow的窗口大小也不对.
传递的数值是1024*768. 实际创建大小为1008*760;
使用MoveWindow,仍然不准确. 系统分辨缩放是100%;
实在找不到原因只好来求助各位大佬. 求帮忙万分感谢.
//创建窗口代码
WNDCLASS WinClass = { 0 };
WinClass.hInstance = hInstance;
WinClass.lpszClassName = ClassName;
WinClass.lpfnWndProc = WndProc;
WinClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
WinClass.hCursor = LoadCursor(NULL, IDC_ARROW);
WinClass.style = CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS;
WinClass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
int WinX = (GetSystemMetrics(SM_CXSCREEN) / 2) - (CL_WinWidth / 2),
WinY = (GetSystemMetrics(SM_CYSCREEN) / 2) - (CL_WinHeight / 2);
if (!RegisterClass(&WinClass))MessageBox(0, L"注册窗口类名失败!", NULL, MB_OK);
G_hWnd = CreateWindow(ClassName, L"萌萌大乱斗单机版",
WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN,
WinX, WinY, CL_WinWidth, CL_WinHeight, NULL, NULL, hInstance, NULL);
if (!G_hWnd)MsgTipExit("窗口创建失败!");
ShowWindow(G_hWnd, SW_SHOWNORMAL);
UpdateWindow(G_hWnd);
MSG msg = { 0 };
while (GetMessage(&msg,NULL,NULL,NULL))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;//获取鼠标坐标; case WM_MOUSEMOVE: MousePoint.KeyCode = wParam; MousePoint.x = GET_X_LPARAM(lParam); MousePoint.y = GET_Y_LPARAM(lParam); break; case WM_LBUTTONDOWN: MousePoint.KeyCode = wParam; MousePoint.KeyState = WM_LBUTTONDOWN; MousePoint.x = GET_X_LPARAM(lParam); MousePoint.y = GET_Y_LPARAM(lParam); break; case WM_RBUTTONDOWN: MousePoint.KeyCode = wParam; MousePoint.KeyState = WM_RBUTTONDOWN; MousePoint.x = GET_X_LPARAM(lParam); MousePoint.y = GET_Y_LPARAM(lParam); break; case WM_LBUTTONUP: MousePoint.KeyCode = wParam; MousePoint.KeyState = WM_LBUTTONUP; MousePoint.x = GET_X_LPARAM(lParam); MousePoint.y = GET_Y_LPARAM(lParam); break; case WM_RBUTTONUP: MousePoint.KeyCode = wParam; MousePoint.KeyState = WM_RBUTTONUP; MousePoint.x = GET_X_LPARAM(lParam); MousePoint.y = GET_Y_LPARAM(lParam); break; default: break;
