void CXXXDlg::SetFullScreen()
{
	int frameWidth =  GetSystemMetrics(SM_CXFRAME);
	int frameHeight = GetSystemMetrics(SM_CYFRAME);
	int captionHeight = GetSystemMetrics(SM_CYCAPTION);
	int screenWidth = GetSystemMetrics(SM_CXSCREEN);
	int screenHeight = GetSystemMetrics(SM_CYSCREEN);
	CRect rect;
	GetClientRect(&rect);
	rect.left = rect.left - frameWidth;
	rect.top = rect.top - frameHeight - captionHeight ;
	rect.bottom = rect.top + screenHeight + 2 * frameHeight + captionHeight;
	rect.right = rect.left + screenWidth + 2 * frameWidth;
	ShowWindow(SW_HIDE);
	SetWindowPos(&wndTopMost, rect.left, rect.top, rect.Width(), rect.Height(), SWP_SHOWWINDOW);
}

实现全屏显示：

在CMainFrame类中实现

private:

BOOL m_bFullScreen; // 全屏显示标志

WINDOWPLACEMENT m_OldWndPlacement; // 用来保存原窗口的位置

CRect m_FullScreenRect; // 表示全屏显示时的窗口位置

初始化

CMainFrame::CMainFrame()

{

// TODO: add member initialization code here

m_bFullScreen = FALSE;

}

添加菜单项以及菜单效应函数

void CMainFrame::OnFullScreen()

{

// TODO: Add your command handler code here

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);

// 将出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TURE

WINDOWPLACEMENT wndpl;

wndpl.length = sizeof(WINDOWPLACEMENT);

wndpl.flags = 0;

wndpl.showCmd = SW_SHOWNORMAL;

wndpl.rcNormalPosition = m_FullScreenRect;

SetWindowPlacement(&wndpl);

}

void CMainFrame::OnUpdateFullScreen(CCmdUI* pCmdUI)

{

// TODO: Add your command update UI handler code here

if (m_bFullScreen)

{

pCmdUI->SetCheck(1);

}

else

{

pCmdUI->SetCheck(0);

}

}

重载CMainFrame类的OnGetMinMaxInfo()函数

void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)

{

// TODO: Add your message handler code here and/or call default

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();

}

CMDIFrameWnd::OnGetMinMaxInfo(lpMMI);

}

在类CMainFrame中添加函数EndFullScreen()。

void CMainFrame::EndFullScreen()

{

if (m_bFullScreen)

{

// 推出全屏显示,恢复原始窗口显示

ShowWindow(SW_HIDE);

SetWindowPlacement(&m_OldWndPlacement);

}

}

下面实现在按下Esc键时，调用EndFullScreen()函数。也即:建立按键与函数之间的联系

// 添加WM_KEYDOWN消息相应函数

void CFullScreenTestView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)

{

// TODO: Add your message handler code here and/or call default

if (nChar == VK_ESCAPE) // 如果按下的是Esc键

{

// 获取主窗口指针

CMainFrame* pFrame = (CMainFrame*) AfxGetApp()->m_pMainWnd;

// 调用主窗口类的自定义函数EndFullScreen(),便可以退出全屏显示模式

pFrame->EndFullScreen();

}

CView::OnKeyDown(nChar, nRepCnt, nFlags);

}
