WinAPI - 윈도우폼에 아이콘 넣기

WinApi 폼에 아이콘 적용할려면 Resource를 활용하여야 합니다.

// Resource.h #define ID_BTN_EXIT           5001 #define IDC_APP                        5002

// Resource.rc #include "Resource.h" IDC_APP ICON "app.ico"

// main.cpp #include <windows.h> #include "Resource.h" HWND btn_Exit; HINSTANCE g_hInst; LRESULT CALLBACK WinProc (HWND, UINT, WPARAM, LPARAM); int WINAPI WinMain (HINSTANCE hThisInstance,                     HINSTANCE hPrevInstance,                     LPSTR lpszArgument,                     int nFunsterStil) { HWND hwnd; MSG messages; WNDCLASSEX wcls; char szClassName[10] = "Icon Test"; g_hInst = hThisInstance; wcls.hInstance = hThisInstance; wcls.lpszClassName = szClassName; wcls.lpfnWndProc = WinProc; wcls.style = CS_DBLCLKS; wcls.cbSize = sizeof (WNDCLASSEX); wcls.hIcon = LoadIcon (g_hInst, MAKEINTRESOURCE(IDC_APP )); wcls.hIconSm = LoadIcon (g_hInst, MAKEINTRESOURCE(IDC_APP)); wcls.hCursor = LoadCursor (NULL, IDC_ARROW); wcls.lpszMenuName = NULL; wcls.cbClsExtra = 0; wcls.cbWndExtra = 0; wcls.hbrBackground = (HBRUSH)COLOR_WINDOW; if (!RegisterClassEx (&wcls)) return 0; hwnd = CreateWindow( szClassName,  szClassName, WS_OVERLAPPEDWINDOW, 0, 0, 300, 300, NULL, NULL, hThisInstance, NULL); ShowWindow (hwnd, nFunsterStil); while (GetMessage (&messages, NULL, 0, 0)) { TranslateMessage(&messages); DispatchMessage(&messages); } return messages.wParam; } LRESULT CALLBACK WinProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) {     switch (message)     {         case WM_CREATE:         btn_Exit = CreateWindow(         "button",         "Exit",         WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,         10,10,70,30,         hwnd,         (HMENU)ID_BTN_EXIT,         g_hInst,         NULL);     break;     case WM_COMMAND :         switch(LOWORD(wParam))         {         case ID_BTN_EXIT :         PostQuitMessage(0);         return 0;         break;         default:         return 0;         }     break;         case WM_DESTROY:             PostQuitMessage (0);             break;         default:             return DefWindowProc (hwnd, message, wParam, lParam);     }     return 0; }

**. 컴파일

windres -i Resource.rc -o Resource.o

g++ *.cpp Resource.o -o TestCode.exe -mwindows

컴파일을 쉽게하기 위해서 배치파일을 만듭니다. Makefile을 만들어서 해도 됩니다.

rem cmd_Build.bat  windres -i Resource.rc -o Resource.o g++ *.cpp Resource.o -o TestCode.exe -mwindows pause
