1、在String Table中设置语句的ID。
2、在CMainFrame下的indicator数组中添加项：
static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
ID_MOUSE,
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
};
3、实例：
void CTestView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CString str;
str.Format("当前鼠标位置：%d,%d",point.x,point.y);
CMainFrame *pmain=(CMainFrame*)AfxGetMainWnd();
CStatusBar *pstatusbar=(CStatusBar*)pmain->GetDescendantWindow(AFX_IDW_STATUS_BAR);
pstatusbar->SetPaneInfo(1,ID_MOUSE,SBPS_POPOUT,150);
pstatusbar->SetPaneText(1,str);;
CView::OnMouseMove(nFlags, point);
}
