LRESULT CALLBACK MainProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam);
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
WNDCLASS wc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
wc.hCursor = LoadCursor(NULL,IDC_ARROW);
wc.hIcon = NULL;
wc.hInstance = hInstance;
wc.lpfnWndProc = MainProc;
wc.lpszClassName = TEXT("Window");
wc.lpszMenuName = NULL;
wc.style = CS_HREDRAW | CS_VREDRAW;
RegisterClass(&wc);
HWND hwnd = CreateWindow(TEXT("Window"),"text",WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,
NULL,NULL,hInstance,NULL);
ShowWindow(hwnd,SW_SHOWNORMAL);
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{
DispatchMessage(&msg);
}
return 0;
}
LRESULT CALLBACK MainProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_CLOSE:
{
DestroyWindow(hwnd);
}
break;
case WM_DESTROY:
{
PostQuitMessage(0);
}
break;
}
return DefWindowProc(hwnd,uMsg,wParam,lParam);
}
以上代码是我用API写的，最简单的只有一个窗口的代码，现在要把它用C++封装成一个窗口类，不要用MFC的那种，就自己封装的，求高手指教！
谢谢！
