1 * 다이렉트드로우내에윈도우대화상자사용하기! 안녕하세요! 라디안소프트김동철입니다! 이번문서강연은다이렉트드로우 7.0 SDK에서 ddraw 예제로포함되었는 FSWindow에대해서정리를해보도록하겠습니다. FSWindow 예제는다이렉트드로우모드내에서윈도우대화상자을띄워서사용할수있는방법을알려준예제였습니다. 전개인적으로이방식이무척이나마음에들었습니다. 게을러서그런지몰라서^_^;;, 맵이나스프라이트툴을제작하기위해서 GDI표면에새로출력을하는방식의윈도우프로그램을제작하기싫어서였다고생각됩니다. 전 MFC에약하기때문에, 대부분윈도우 API를이용해서프로그램을코딩합니다.! 그전엔맵툴이나스프라이트툴을만들기위해서다이렉트드로우기반에서모든인터페이스를만들어서 ( 그려서 ) 사용을했었습니다. 아직도그툴을개선해서사용하고있습니다. ㅎㅎ하지만, 어떤기능을추가하고자할때마다인터페이스를새로만들고, 좌표를잡아주고기능을하게만드는단순작업이무척이나많았습니다. 하지만 FSWindow의예제처럼일반다이렉트드로우환경에서윈도우대화상자를바로이용할수있다는것은단순하고시간이많이걸리는인터페이스작업을빠르게할수있게해주었습니다. 전이방식을이용해서스프라이트툴이나맵툴, 간이이펙트, 기타편집툴을을만들어서사용합니다. 이방식이좋은점은최종완성된게임에서보이는화면에서동일한화면에서스프라이트, 맵작업을하기때문에게임의완성되었을때의최종모습을보면서작업을하는것과같아서, 이미지나맵의문제점을바로찾을수가있다는것이죠, 그리고, 스프라트에디터나, 맵에디터에서사용한그래픽출력엔진코드를그대로메인게임소스쪽으로가져다쓸수있기때문에제작시간을단축할수있습니다. 복잡한기능들을다가지고있는범용툴보다특정프로그램에특화된툴을빨리만드는데는무척이나도움이됩니다. 이프로그래밍방식역시한번사용하고나서, 나중에다시제작을하려면또다시전체를들여다보는번거로움이저에게있었습니다. 그래서이번기회에정리한다는생각에서자료를준비했습니다. 전번 KGDA 강연에서는게임용인스톨쉴드의작업하기였는데, 그역시지금의이유와동일한목적에서제작한것으로기억이남니다. 벌써 1년이지나갔군요, 개인적으로는별로한일없이시간만흐른것같습니다. 먼저 FSWindow의예제를불필요한공의에니메이션은제거하고필요한다이얼로그의이용법과어떻게내프로그램에가져다사용할것인가대해서다루어보도록하겠습니다. 또한보너스로현재예제로제공되는소스는디버깅모드에서는창모드로, 리테일모드에서는풀화면으로실행되도록코드내에작업해놓았습니다. 이렇게해놓으니디버깅이쉬워지는군요, 그전까지디버깅은오로지눈치와직감으로그리고메시지상자를이용한노가다, 화면에메시지출력방식으로해왔는데, 이렇게하니컴파일러의디버깅기능에도움을많이받게되는군요.. ㅎㅎ 사용하는방법은다이렉트드로우예제에있는 fswindow.h fswindow.cpp를프로젝트에포함시키는것을먼저해야합니다.

2 그다음은초기화하고, 사용하면됩니다. 먼저메인프로그램헤더에다음변수들을선언해줍니다. #include fswindow.h //*************************************************************************************** // 아래변수들은대화상자를컨트롤하는변수입니다. HWND g_hwndhelp = NULL; HWND g_hwnd_workdlg = NULL; // 작업메뉴다이얼박스 // 대화상자내에입력을처리하는콜백함수 ^_^;; LRESULT CALLBACK Dial_MainMenu_Proc(HWND hdlg, UINT umsg, WPARAM wparam, LPARAM lparam); //*************************************************************************************** 다른이름으로변수선언을해도상관없지만, 귀찮아서그냥가져다가사용합니다 ^_^;; 선언이끝났으면, 다이렉트드로우초기화를한이후에대화상자를처리해주는부분을초기화합니다. //>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // 다이렉트드로우화면에대화상자사용을위한초기화작업 // 아래함수호출을해서대화상자를컨트롤해줄부분을초기화해줌니다.

SetWindowPos(g_hWnd_WorkDlg,HWND_TOP,g_rcWindow.left+550,g_rcWindow.top+10,0,0,SWP_NOSIZE); ShowWindow(g_hWnd_WorkDlg, SW_SHOWNORMAL); //*************************************************************************************** 대화상자를생성하고, 위치는화면중앙에서오른쪽으로이동시켜놓습니다. 인터페이스이니까, 화면가운데떵하고띄워지면, 뻘쭘하겠죠 //>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // fswindow 시작, 아래함수가실행되면다이렉트드로우화면상에대화상자가나타납니다. g_hwndhelp = FSWindow_Begin(g_hWnd_WorkDlg, FALSE); //>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

3 위의과정이처음다이렉트드로우표면상에대화상자를만드는작업입니다. 하지만, 다음에해야할부분이중요합니다. 아래설명한부분까지작업을해야정상적으로대화상자를볼수가있습니다. while( 1 ) if( PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE ) ) if(!getmessage( &msg, NULL, 0, 0 ) ) return msg.wparam; //>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // 대화상자가보여지면, 모달리스대화상자를위해서메시지를교환시킨다. if (g_hwnd_workdlg == (HWND )NULL!IsDialogMessage(g_hWnd_WorkDlg, &msg)) // 메시지의번역과패치를하는곳 TranslateMessage(&msg); DispatchMessage(&msg); //>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> else if(blsactive) DDUpdateFrame(); // 화면업데이트. else WaitMessage(); // 메지지없으면기다리기. 위의코드를보면메인프로그램코드의어느부분인지아실겁니다. 내응용프로그램에서메시지를받고처리하는메인코드부분이지죠, 다이렉트드로우내에나타나게한대화상자를위한메시지처리를해주는부분입니다. 위처럼라인 > 이그려져있는안쪽부분을가져다사용하시면되겠습니다. 다음을실제화면출력을해주를함수내부에다음과같이코드를수정합니다.
