在VC++6.0开发中实现全屏显示(2)
// 将除控制条外的客户区全屏显示到从(0,0)到(nFullWidth, nFullHeight)区域, 将(0,0)和(nFullWidth, nFullHeight)两个点外扩充原窗口和除控制条之外的 客户区位置间的差值, 就得到全屏显示的窗口位置
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;
m_bFullScreen=TRUE; // 设置全屏显示标志为 TRUE
// 进入全屏显示状态
WINDOWPLACEMENT wndpl;
wndpl.length=sizeof(WINDOWPLACEMENT);
wndpl.flags=0;
wndpl.showCmd=SW_SHOWNORMAL;
wndpl.rcNormalPosition=m_FullScreenRect;
SetWindowPlacement(&wndpl);}
4)重载CMainFrame类的OnGetMinMaxInfo函数,在全屏显示时提供全屏显示的位置信息。
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{if(m_bFullScreen)
{lpMMI->ptMaxSize.x=m_FullScreenRect.Width();
lpMMI->ptMaxSize.y=m_FullScreenRect.Height();
lpMMI->ptMaxPosition.x=m_FullScreenRect.Width();
lpMMI->ptMaxPosition.y=m_FullScreenRect.Height();
// 最大的Track尺寸也要改变
lpMMI->ptMaxTrackSize.x=m_FullScreenRect.Width();
lpMMI->ptMaxTrackSize.y=m_FullScreenRect.Height();
}CFrameWnd::OnGetMinMaxInfo(lpMMI)
