新建MFC对话框应用程序

在FullTestDlg.h : 头文件添加变量

private:

BOOL bFullScreen;

WINDOWPLACEMENT m_struOldWndpl;

  1. private:
  2.     BOOL bFullScreen;
  3.     WINDOWPLACEMENT m_struOldWndpl;

// FullTestDlg.cpp : 实现文件

void CFullTestDlg::OnBnClickedButtonFull()

{

//MessageBox(_T(“测试”));

int iShowStat = bFullScreen?SW_HIDE:SW_SHOW;

if (!bFullScreen)

{

//get current system resolution

int g_iCurScreenWidth = GetSystemMetrics(SM_CXSCREEN);

int g_iCurScreenHeight = GetSystemMetrics(SM_CYSCREEN);

//for full screen while backplay

GetWindowPlacement(&m_struOldWndpl);

CRect rectWholeDlg;//entire client(including title bar)

CRect rectClient;//client area(not including title bar)

CRect rectFullScreen;

GetWindowRect(&rectWholeDlg);

RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, reposQuery, &rectClient);

ClientToScreen(&rectClient);

rectFullScreen.left = rectWholeDlg.left-rectClient.left;

rectFullScreen.top = rectWholeDlg.top-rectClient.top;

rectFullScreen.right = rectWholeDlg.right+g_iCurScreenWidth - rectClient.right;

rectFullScreen.bottom = rectWholeDlg.bottom+g_iCurScreenHeight - rectClient.bottom;

//enter into full screen;

WINDOWPLACEMENT struWndpl;

struWndpl.length = sizeof(WINDOWPLACEMENT);

struWndpl.flags = 0;

struWndpl.showCmd = SW_SHOWNORMAL;

struWndpl.rcNormalPosition = rectFullScreen;

SetWindowPlacement(&struWndpl);

bFullScreen=true;

}

}

  1. void CFullTestDlg::OnBnClickedButtonFull()
  2. {
  3.     //MessageBox(_T("测试"));
  6.     int iShowStat = bFullScreen?SW_HIDE:SW_SHOW;
  8.     if (!bFullScreen)
  9.     {
  10.         //get current system resolution
  11.         int g_iCurScreenWidth = GetSystemMetrics(SM_CXSCREEN);
  12.         int g_iCurScreenHeight = GetSystemMetrics(SM_CYSCREEN);
  14.         //for full screen while backplay
  15.         GetWindowPlacement(&m_struOldWndpl);
  17.         CRect rectWholeDlg;//entire client(including title bar)
  18.         CRect rectClient;//client area(not including title bar)
  19.         CRect rectFullScreen;
  20.         GetWindowRect(&rectWholeDlg);
  21.         RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, reposQuery, &rectClient);
  22.         ClientToScreen(&rectClient);
  24.         rectFullScreen.left = rectWholeDlg.left-rectClient.left;
  25.         rectFullScreen.top = rectWholeDlg.top-rectClient.top;
  26.         rectFullScreen.right = rectWholeDlg.right+g_iCurScreenWidth - rectClient.right;
  27.         rectFullScreen.bottom = rectWholeDlg.bottom+g_iCurScreenHeight - rectClient.bottom;
  28.         //enter into full screen;
  29.         WINDOWPLACEMENT struWndpl;
  30.         struWndpl.length = sizeof(WINDOWPLACEMENT);
  31.         struWndpl.flags = 0;
  32.         struWndpl.showCmd = SW_SHOWNORMAL;
  33.         struWndpl.rcNormalPosition = rectFullScreen;
  34.         SetWindowPlacement(&struWndpl);
  36.         bFullScreen=true;
  37.     }
  39. }

增加右键消息处理函数，退出全屏模式

void CFullTestDlg::OnRButtonDown(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

if(bFullScreen){

SetWindowPlacement(&m_struOldWndpl);

bFullScreen=false;

}

CDialog::OnRButtonDown(nFlags, point);

}
