我一直在改进我一直致力于的类(class)，其中之一就是创建库来处理某些在我的主项目中并不真正需要看到的任务。但是，当我调用该类并实例化我刚刚创建的库时，我得到:
Intellisense: argument of type "HWND" is incompatible with parameter of type "rawData::HWND"
当我从库中调用一个方法并传递这些参数时会发生这种情况(错误在第一个参数中):
// register the window for touch instead of gestures
rawData::RegisterTouchWindow(hWnd, 0);
完整代码在这里:
//Creates the main window
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = szWindowClass;
wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
if (!RegisterClassEx(&wcex))
{
MessageBox(NULL,
_T("Call to RegisterClassEx failed!"),
_T("Win32 Guided Tour"),
NULL);
return 1;
}
hInst = hInstance; // Store instance handle in our global variable
// The parameters to CreateWindow explained:
// szWindowClass: the name of the application
// szTitle: the text that appears in the title bar
// WS_OVERLAPPEDWINDOW: the type of window to create
// CW_USEDEFAULT, CW_USEDEFAULT: initial position (x, y)
// 500, 100: initial size (width, length)
// NULL: the parent of this window
// NULL: this application does not have a menu bar
// hInstance: the first parameter from WinMain
// NULL: not used in this application
HWND hWnd = CreateWindow(
szWindowClass,
szTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
800, 600,
NULL,
NULL,
hInstance,
NULL
);
if (!hWnd) {
MessageBox(NULL,
_T("Call to CreateWindow failed!"),
_T("Win32 Guided Tour"),
NULL);
return 1;
}
// register the window for touch instead of gestures
/*ERROR HERE*/rawTData::RegisterTouchWindow(hWnd, 0);/*ERROR HERE*/
// the following code initializes the points
for (int i=0; i< MAXPOINTS; i++){
points[i][0] = -1;
points[i][1] = -1;
idLookup[i] = -1;
}
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
// Main message loop:
MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return (int) msg.wParam;
}
我访问了一些网站，他们建议使用“this->”来指定您指向的变量，但是当我尝试时没有任何显示。这就是为什么我来这里看看是否有人遇到过这种情况。任何一点帮助将不胜感激。提前致谢!

最佳答案
通过将所有内容放入您自己的 namespace rawTData，您已声明所有这些类型都属于 rawTData。 HWND 是一种 Windows API 类型，不等同于您的定义(rawTData::HWND)一堆您不希望 Intellisense 显示的代码，它们将名称“隐藏”在类似目录的结构中。一个简单的解决方法是将 namespace rawTData { 向下移动到您自己的声明之上，但这引出了一个问题:为什么要将 everything 包装在 namespace rawTData?
看起来您已将一堆 Windows.h 定义剪切并粘贴到您自己的命名空间中。您真的应该只包含适当的文件。如果这不起作用，则可能还有其他问题需要解决，您不应该像这样通过复制粘贴来绕过它。
关于c++ - 智能感知 : argument of type "HWND" is incompatible with parameter of type "rawData::HWND"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20106592/
