MFCGridCtrl OnEraseBkgnd ScrollBar Redraw

MFC Dialog Color 를 바꾸기 위해

OnEraseBkgnd 을 오버라이딩하여 사용하면

Dialog 를 새로 그리게 되는데

이때 CGridCtrl 의 스크롤바 영역도 같이 새로 그리게 된다.

그래서 스크롤바가 존재하지만 안보이는 경우가 발생한다.

그럴때는 OnEraseBkgnd 에서 Dialog 를 새로그린 다음

m_Grid.SetRedraw(true, true);

Redraw 를 하면

스크롤 바를 새로 그린다.

MFCGridCtrl CGridCtrl ScrollBar Visible

If you change Dialog color used by OnEraseBkgnd();

you can't see CGridCtrl's ScrollBar

in that case, you should add m_Grid.SetRedraw(true, true); to OnEraseBkgnd();

BOOL CMyDialog::OnEraseBkgnd(CDC* pDC)
{
	// TODO: 여기에 메시지 처리기 코드를 추가 및/또는 기본값을 호출합니다.

	CRect rect;

	GetClientRect(&rect);

	CBrush myBrush(RGB(255, 255, 255));    // dialog background color <- 요기 바꾸면 됨.
	
	CBrush *pOld = pDC->SelectObject(&myBrush);

	BOOL bRes = pDC->PatBlt(0, 0, rect.Width(), rect.Height(), PATCOPY);

	pDC->SelectObject(pOld);    // restore old brush

	m_Grid.SetRedraw(true, true);

	return bRes;                       // 	return CDialog::OnEraseBkgnd(pDC);
}

MFC CGridCtrl Color Change

COLORREF ItemBkColour = RGB(255,255,255);

m_Grid.SetItemBkColour(0, 0, ItemBkColour);

m_Grid.SetItemBkColour(0, 1, ItemBkColour);

m_Grid.SetItemBkColour(0, 2, ItemBkColour);

m_Grid.SetItemBkColour(0, 3, ItemBkColour);

m_Grid.SetBkColor(RGB(255, 0, 0));
