如何让client区全屏显示？

[fat_how]

注意：不是最大化
要求：
*没有标题栏，没有toolbar,statusbar

*而且可以动态切换回normal态

*mfc代码

[fat_how]

这段代码我试过了

屏幕上开始菜单那一行还是会盖掉client

[howtotell]

再MainFrm.h中
private:
WINDOWPLACEMENT m_OldWndPlacement;//用来保存原窗口位置
CRect m_FullScreenRect;//表示全屏显示时的窗口位置
BOOL m_bFullScreen;//全屏显示标志

void CMainFrame::OnFullScreen() //切换到全屏方式
{
if(m_bFullScreen)
return;
GetWindowPlacement(&m_OldWndPlacement);
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);
//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);

}

//重载的函数
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);
}


void CMainFrame::OnEndFullScreen()//切换回正常模式
{
if(m_bFullScreen)
{
ShowWindow(SW_HIDE);
SetWindowPlacement(&m_OldWndPlacement);
m_bFullScreen=FALSE;
}
}
给分!

在CMainFrame类中添加下列成员变量和成员函数(使用ClassWizard)，下面是这些变量和函数的功能说明：

成员变量：
BOOL m_bFullScreen; //全屏幕显示标志
CRect m_FullScreenWindowRect; //全屏幕显示窗口Rect
WINDOWPLACEMENT m_wpPrev; //用于保存正常视图时的窗口位置信息
CToolBar * m_wndFullScreenBar; //全屏幕显示时的浮动工具条

成员函数：
void OnMenuFullscreen(); //全屏幕显示的处理函数
void OnGetMinMaxInfo(); //捕获WM_GETMINMAXINFO消息以便允许你增加窗口大小
void OnUpdateViewFullScreen(); //更新“全屏幕显示”菜单的状态

源码

void CMainFrame::OnMenuFullscreen()
{//全屏幕显示的处理函数
RECT rectDesktop;
WINDOWPLACEMENT wpNew;

if (m_bFullScreen)
{//全屏幕显示模式
//隐藏工具条和状态条
m_wndStatusBar.ShowWindow(SW_HIDE);
m_wndToolBar.ShowWindow(SW_HIDE);

//保存正常视图时的窗口位置信息以便恢复原来状态
GetWindowPlacement (&m_wpPrev);
m_wpPrev.length = sizeof m_wpPrev;

//调整RECT为新的窗口尺寸
::GetWindowRect ( ::GetDesktopWindow(), &rectDesktop );
::AdjustWindowRectEx(&rectDesktop, GetStyle(), TRUE, GetExStyle());

//保存RECT以便OnGetMinMaxInfo()使用
m_FullScreenWindowRect = rectDesktop;

wpNew = m_wpPrev;
wpNew.showCmd = SW_SHOWNORMAL;
wpNew.rcNormalPosition = rectDesktop;

//生成新的工具条
m_wndFullScreenBar=new CToolBar;

if(!m_wndFullScreenBar->Create(this, CBRS_SIZE_DYNAMIC|CBRS_FLOATING)
|| !m_wndFullScreenBar->LoadToolBar(IDR_FULLSCREEN))
{
TRACE0("Failed to create toolbar\n");
return; // fail to create
}

//不允许工具条停泊
m_wndFullScreenBar->EnableDocking(FALSE);
m_wndFullScreenBar->SetWindowPos(0,100,100,0,0,SWP_NOSIZE
|SWP_NOZORDER|SWP_NOACTIVATE|SWP_SHOWWINDOW);
m_wndFullScreenBar->SetWindowText(_T("全屏幕显示"));
FloatControlBar(m_wndFullScreenBar, CPoint(100,100));
m_bFullScreen=TRUE;
}
else
{//正常显示模式
//删除全屏幕工具条
m_wndFullScreenBar->DestroyWindow();
delete m_wndFullScreenBar;

m_bFullScreen=FALSE;

//恢复工具条和状态条
m_wndStatusBar.ShowWindow(SW_SHOWNORMAL);
m_wndToolBar.ShowWindow(SW_SHOWNORMAL);
wpNew = m_wpPrev;
}

//设置窗口显示状态
SetWindowPlacement ( &wpNew );
}

void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
if (m_bFullScreen)
{
lpMMI->ptMaxSize.y = m_FullScreenWindowRect.Height();
lpMMI->ptMaxTrackSize.y = lpMMI->ptMaxSize.y;
lpMMI->ptMaxSize.x = m_FullScreenWindowRect.Width();
lpMMI->ptMaxTrackSize.x = lpMMI->ptMaxSize.x;
}
}

void CMainFrame::OnUpdateMenuFullscreen(CCmdUI* pCmdUI)
{//更新菜单的状态
pCmdUI->Enable();
pCmdUI->SetCheck(m_bFullScreen);
}
