void CMainFrame::OnFullScreen()
{
CRect WindowRect;
GetWindowRect(&WindowRect);
CRect ClientRect;
RepositionBars(0,0xffff,AFX_IDW_PANE_FIRST,reposQuery,&ClientRect);
ClientToScreen(&ClientRect);
//获取屏幕的分辨率
int nFullWidth=GetSystemMetrics(SM_CXSCREEN);
int nFullHeight=GetSystemMetrics(SM_CYSCREEN);
m_FullScreenRect.left=WindowRect.left-ClientRect.left;
m_FullScreenRect.top=WindowRect.top-ClientRect.top;
m_FullScreenRect.right=WindowRect.right-ClientRect.right+nFullWidth;
m_FullScreenRect.bottom=WindowRect.bottom-ClientRect.bottom+nFullHeight;
//进入全屏显示状态
WINDOWPLACEMENT wndpl;
wndpl.rcNormalPosition=m_FullScreenRect;
SetWindowPlacement(&wndpl);
}
MFC中全屏显示增加的一个函数，RepositionBars(0,0xffff,AFX_IDW_PANE_FIRST,reposQuery,&ClientRect);
的作用是什么，谁帮帮我解释下这个函数的作用，特别是每个参数，AFX_IDW_PANE_FIRST的含义？
