在为我的 windows 类完成包装后,我用一些文本进行了测试,以确保一切正常。但是,无论我删除或注释掉文本“这是一个测试!!!!”,在运行程序时,它在可执行文件运行期间仍然存在。
LRESULT CALLBACK WinMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_PAINT:
PAINTSTRUCT ps;
HDC hdc;
//hdc = BeginPaint(hwnd, &ps);
//TextOut(hdc, 0, 0, L"This is a TEST!!!", 17);
//EndPaint(hwnd, &ps);
break;
case WM_DESTROY:
bWindowClosed = TRUE;
break;
case WM_CREATE:
MessageBox(NULL, L"Create", L"test", MB_OK);
break;
default:
return CBaseWindow::WinMsgHandler(hwnd, uMsg, wParam, lParam);
}
return 0;
};
编辑:
这是winmain源文件。我觉得这与我将所有内容括起来的方式有关。CDerivedWindow 是一个封装类,用于封装大部分窗口初始化过程。
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
CDerivedWindow mainWnd(hInstance);
WNDCLASSEX wcx;
// Fill in the window class structure with default parameters
wcx.cbSize = sizeof(WNDCLASSEX); // size of structure
wcx.style = CS_HREDRAW | CS_VREDRAW; // redraw if size changes
wcx.lpfnWndProc = CBaseWindow::stWinMsgHandler; // points to window procedure
wcx.cbClsExtra = 0; // no extra class memory
wcx.cbWndExtra = 0; // no extra window memory
wcx.hInstance = hInstance; // handle to instance
wcx.hIcon = LoadIcon(NULL, IDI_APPLICATION); // predefined app. icon
wcx.hCursor = LoadCursor(NULL, IDC_ARROW); // predefined arrow
wcx.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH); // white background brush
wcx.lpszMenuName = NULL; // name of menu resource
wcx.lpszClassName = L"True Wild"; // name of window class
wcx.hIconSm = LoadIcon(NULL, IDI_APPLICATION); // small class icon
initSprites();
// register the window
if (mainWnd.RegisterWindow(&wcx))
{
DWORD dwError = 0;
DWORD dwStyle = WS_OVERLAPPEDWINDOW | WS_VISIBLE;
RECT rc;
rc.top = 100;
rc.left = 100;
rc.right = SCREEN_WIDTH;
rc.bottom = SCREEN_HEIGHT;
// create the window and start the message loop
// we will get kicked out of the message loop when the window closes
if (mainWnd.Create(dwStyle, &rc))
{
// message loop
MSG msg;
//game Loop
while (TRUE)
{
while(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
// Translate the message and dispatch it to WindowProc()
TranslateMessage(&msg);
DispatchMessage(&msg);
if (mainWnd.IsWindowClosed())
return 0;
}
//Run game code
render();
}
return 0;
}
else
return -1;
}
else
return -2;
return 0;
}
编辑答案1:
// the message handler for this window
LRESULT CALLBACK WinMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_DESTROY:
bWindowClosed = TRUE;
break;
default:
return DefWindowProc(hwnd, uMsg, wParam, lParam);
}
return DefWindowProc(hwnd, uMsg, wParam, lParam);
};
