视频播放器的制作，视频流在静态控件上显示，类似迅雷看看双击全屏操作的实现。
方法一 在debug和 release下都行
先在工程中先创建一个新类MyStatic 其基类是CDialog
在主窗口的类向导中给静态控件关联一个变量 CMyStatic m_videoWnd
然后在主窗口的.h中定义一个变量用来判断是否全屏 BOOL m_isFullScreen
在主窗口的.h中定义一个变量 CRect m_Old 用来存储静态控件相对对话框的位置
在主窗口的.ccp文件中的OnInitDialog()函数中初始化相对位置：
m_videoWnd.GetWindowRect(&m_Old);
ScreenToClient(&m_Old);
现在填写新类MyStatic中的代码MyStatic.h
//MyStatic.h
#if !defined(AFX_MYSTATIC_H__7894AB02_E0B0_412B_9D94_24645AC34A0D__INCLUDED_)
#define AFX_MYSTATIC_H__7894AB02_E0B0_412B_9D94_24645AC34A0D__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
// MyStatic.h : header file

// CMyStatic message handlers
void CMyStatic::OnLButtonDblClk(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
if (m_pDemoDlg->m_isFullScreen == FALSE)
{
SetParent(GetDesktopWindow());
CRect rect;
GetDesktopWindow()-> GetWindowRect(&rect);
SetWindowPos(&wndTopMost,rect.left,rect.top,rect.right,rect.bottom,SWP_SHOWWINDOW);
// m_pDemoDlg->ShowWindow(SW_HIDE);
m_pDemoDlg->m_isFullScreen = TRUE;
}
else
{
m_pDemoDlg->ShowWindow(SW_SHOW);
SetParent(m_pDemoDlg);
SetWindowPos(&wndTop,m_pDemoDlg->m_Old.left,m_pDemoDlg->m_Old.top,
m_pDemoDlg->m_Old.right-m_pDemoDlg->m_Old.left,
m_pDemoDlg->m_Old.bottom-m_pDemoDlg->m_Old.top,SWP_SHOWWINDOW);
m_pDemoDlg->m_isFullScreen = FALSE;
}
CStatic::OnLButtonDblClk(nFlags, point);
}
到这里就可以实现了,最后想按esc退出全屏.需要在主窗口中.h文件加添加一个（可以写代码也可以在类向导中添加这个消息获取函数）
public:
virtual BOOL PreTranslateMessage(MSG* pMsg);
在主窗口的.cpp中
BOOL CTestVoxCVSA_DemoDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
if ((m_isFullScreen == TRUE)&&(pMsg->message==WM_KEYDOWN)&&(pMsg->wParam==VK_ESCAPE))
{
m_pDemoDlg->ShowWindow(SW_SHOW);
m_videoWnd.SetParent(m_pDemoDlg);
m_videoWnd.SetWindowPos(&wndTop,m_Old.left,m_Old.top,m_Old.right-m_Old.left,m_Old.bottom-m_Old.top,SWP_SHOWWINDOW);
m_isFullScreen = FALSE;
return TRUE;
}
return CDialog::PreTranslateMessage(pMsg);
}
方法二 在debug下可以运行，但在release下不行
在主窗口的 .h 文件中
BOOL m_isFullScreen;
CRect m_Old;
BOOL PreTranslateMessage(MSG* pMsg);
nbsp;afx_msg void OnDoubleStatic(UINT nFlags,CPoint point); //双击静态控件（显示视频）响应函数
.cpp文件中
//定义消息相应
ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic) ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic)
//在主窗口 .cpp 文件中的初始化函数中先获取原始的位置
m_videoWnd.GetWindowRect(&m_Old);
ScreenToClient(&m_Old);
在主窗口 .cpp 文件中
//
void CTestVoxCVSA_DemoDlg::OnDoubleStatic(UINT nFlags,CPoint point)
{
CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
if (m_isFullScreen == FALSE)
{
CWnd *saveParent=m_videoWnd.GetParent();
m_videoWnd.SetParent(GetDesktopWindow());
CRect rect;
GetDesktopWindow()-> GetWindowRect(&rect);
m_videoWnd.SetWindowPos(&wndTopMost,rect.left,rect.top,rect.right,rect.bottom,SWP_SHOWWINDOW);
m_pDemoDlg->ShowWindow(SW_HIDE);
m_isFullScreen = TRUE;
}
CDialog::OnLButtonDblClk(nFlags,point);
}
//获取消息的函数
BOOL CTestVoxCVSA_DemoDlg::PreTranslateMessage(MSG* pMsg)
{
CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
if ((pMsg->message==WM_LBUTTONDBLCLK)&&(m_isFullScreen == TRUE))
{
m_pDemoDlg->ShowWindow(SW_SHOW);
m_videoWnd.SetParent(m_pDemoDlg);
m_videoWnd.SetWindowPos(&wndTop,m_Old.left,m_Old.top,m_Old.right-m_Old.left,m_Old.bottom-m_Old.top,SWP_SHOWWINDOW);
m_isFullScreen = FALSE;
return TRUE;
}
return CWnd::PreTranslateMessage(pMsg);
}
如果想要对话框内部窗口全屏
void CMFullScreenDlg::OnLButtonDblClk(UINT nFlags, CPoint point)
{
if(m_isFullScreen)
{
ModifyStyle(WS_POPUP,WS_CAPTION);
SetWindowPlacement(&m_winplacement);
m_isFullScreen=false;
}
else
{ //全屏显示
ModifyStyle(WS_CAPTION,WS_POPUP);
GetWindowPlacement(&m_winplacement);
int x=::GetSystemMetrics(SM_CXSCREEN);
int y=::GetSystemMetrics(SM_CYSCREEN);
WINDOWPLACEMENT winplacement;
winplacement.showCmd=SW_SHOWNORMAL;
winplacement.length=sizeof(WINDOWPLACEMENT);
winplacement.rcNormalPosition.left=0;
winplacement.rcNormalPosition.top=0;
winplacement.rcNormalPosition.right=x;
winplacement.rcNormalPosition.bottom=y;
winplacement.flags=0;
SetWindowPlacement(&winplacement);
m_isFullScreen=true;
}
CDialog::OnLButtonDblClk(nFlags, point);
}
