在CMainFrame类下添加变量:
public:
BOOL m_bFullScreenMode; //全屏显示标志
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
添加函数:
public:
void FullScreenModeOn();
void FullScreenModeOff();
重载函数(自己也不算太明白):
void OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI);
内容为:
void CMainFrame::FullScreenModeOn()
{
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_bFullScreenMode = 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);
m_bFullScreenMode=true;
}
void CMainFrame::FullScreenModeOff()
{
ShowWindow(SW_HIDE);
SetWindowPlacement(&m_OldWndPlacement);
m_bFullScreenMode=false;
}
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
if(m_bFullScreenMode)
{
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) ;
}
对CMainFrame类改动到此为止。
只需要在view中添加消息,获取CMainFrame的指针pWnd,调用FullScreenModeOn/Off()即可。
