在vc环境下什么函数可以移动光标到指定位置

Answer 1

// initialize the cursor array
_afxCursors[0] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNWSE));
_afxCursors[1] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNESW));
_afxCursors[2] = _afxCursors[0];
_afxCursors[3] = _afxCursors[1];
_afxCursors[4] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNS));
_afxCursors[5] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKWE));
_afxCursors[6] = _afxCursors[4];
_afxCursors[7] = _afxCursors[5];
_afxCursors[8] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACK4WAY));
_afxCursors[9] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_MOVE4WAY));
{
// trackers should only be in client area
if (nHitTest != HTCLIENT)
return FALSE;
// convert cursor position to client co-ordinates
CPoint point;
GetCursorPos(&point);
pWnd->ScreenToClient(&point);
// do hittest and normalize hit
int nHandle = HitTestHandles(point);
if (nHandle < 0)
return FALSE;
// need to normalize the hittest such that we get proper cursors
nHandle = NormalizeHit(nHandle);
// handle special case of hitting area between handles
// (logically the same -- handled as a move -- but different cursor)
if (nHandle == hitMiddle && !m_rect.PtInRect(point))
{
// only for trackers with hatchedBorder (ie. in-place resizing)
if (m_nStyle & hatchedBorder)
nHandle = (TrackerHit)9;
}
//ASSERT(nHandle < _countof(_afxCursors));
::SetCursor(_afxCursors[nHandle]);
