MainFrame, Doc, View 포인터 얻기

1. MainFrame 포인터 얻기

CMainFrame *frame = (CMainFrame*)AfxGetMainWnd();

2. Doc 클래스 포인터 얻기
CxxxDoc *pDoc = (CxxxDoc*)(frame->GetActivedocument());

3. View 클래스 포인터 얻기
CxxxView* pView = (CxxxView*)((CMainFrame*)(AfxGetApp()->m_pMainWnd))->GetActiveView();

자주쓰이는 MFC 클래스 간의 통신입니다. 외워쓰기에는 시간이 아깝고, 매번 찾으려면 귀찮았는데 한번에 모아놓으니 편리하네요.^^

[SDI 형태]

1. MainFrame 얻기
- CMainFrame *pFrame = (CmainFrame *) AfxGetMainWnd();

2. App 포인터 얻기
- CTestApp *pApp = (CtestApp *) AfxGetApp();

3. Document 포인터 얻기
- CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
  CTestDoc *pDoc = (CTestDoc *)pFrame->GetActiveDocument();
- CTestDoc *pDoc = ((CMainFrame *)AfxGetMainWnd())->GetActiveDocument();

4. View 포인터 얻기
- CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
  CTestView *pView = (CTestView *)pFrame->GetActiveView();
- CTestView *pView = ((CMainFrame *)AfxGetMainWnd())->GetActiveView();

 

 

[MDI 형태]

1. ChildFrame 포인터 얻기
- CMainFrame *pFrame = (CMainFrame *)AfxGetMainWnd();
  CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
- CChildFrame *pChild = ((CMainFrame *)AfxGetMainWnd())->GetActiveFrame();

2. Document 포인터 얻기
- CMainFrame *pFrame = (CMainFrame)AfxGetMainWnd();
  CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
  CMdiTestDoc *pDoc = (CMdiTestDoc *)pChild->GetActiveDocument();
- CMdiTestDoc *pDoc = (((CMainFrame *)AfxGetMainWnd())->GetActiveFrame())->GetActiveDocument();

3. View 포인터 얻기

- CCainFrame *pFrame = (CMainFrame)AfxGetMainWnd();
  CChildFrame *pChild = (CChildFrame *)pFrame->GetActiveFrame();
  CMdiTestView *pView = (CMdiTestDoc *)pChild->GetActiveView();
- CMdiTestView *pView = (((CMainFrame *)AfxGetMainWnd())->GetActiveFrame())->GetActiveView();
