How to handle alt-tab when playing full screen over TGE
Posted: Sat Jan 29, 2011 12:47 am
Hi there,
First let me say thank you for a good working product. Using your DLL for my client company, I have been able to bring their game to the windows 7 platform.
The game plays flash movies/games as mini games or cutscrenes over a window owned by the main game built using Torque Game Engine. I had to use a few non-obvious function calls to get the movies to play correctly over the TGE window in full screen.
I am having one issue that I am having trouble resolving. I am creating a full screen flash window using WS_POPUP style (code below..), and I get it to play fine, but I do not handle alt-tab properly yet and thats my question. How to handle alt-tab and then alt tab back. I believe its the same issue for click on the second screen causing the flash movie to lose focus.
I would like that the flash application paused and then resumed, but I do not see an easy way to do this with the current API. I tried to just stop and then play again. I can stop the movie at the first alt tab, but it does not want to play when I tab back, though I know my code is executing via file prints, and that includes a FPC_Play call. Let me show the relevant code....
First the meat of the window initialize call...
Now the heart of the play movie in window code
Finally the code I have been using to try and handle to losing and gaining of focus in the windowProc message handling function for the WM_ACTIVATEAPP message type.
I have tried lots of combinations of calls, as you might tell from commented out code. Any suggestions on how to handle this? I am more a game engine coder than a windows messaging type coder , so any help is greatly appreciated.

Let me show the relevant code....
First the meat of the window initialize call...
Code: Select all
m_hwndFlashPlayerControl = CreateWindow((LPCTSTR)FPC_GetClassAtom(m_hFPC),
//NULL, WS_POPUP | WS_VISIBLE,
NULL, WS_POPUP,
rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top,
hWnd, NULL, NULL, NULL);
if ( FPC_GetVersion(FPC_GetHFPC(m_hwndFlashPlayerControl)) >= DEF_MINIMAL_FLASH_VERSION_THAT_ALLOWS_FULLSCREEN )
// Allowfullscreen is available
{
FPC_EnableFullScreen(m_hwndFlashPlayerControl, TRUE);
}
// Associate my "this" pointer
SetWindowLong (m_hwndFlashPlayerControl, GWL_USERDATA, (LONG) this);
// save old window proc
m_OldWndProc = (WNDPROC)GetWindowLong(m_hwndFlashPlayerControl, GWL_WNDPROC);
// set new window proc
SetWindowLong(m_hwndFlashPlayerControl, GWL_WNDPROC, (long) windowProc);
// if window set focus
if (IsWindow(m_hwndFlashPlayerControl))
mhOldFocusWnd = ::SetFocus(m_hwndFlashPlayerControl);
// set event listener and reset window position to get it to play
if (m_hwndFlashPlayerControl != NULL)
{
FPCSetEventListener(m_hwndFlashPlayerControl, FPCListener, (LPARAM)(this));
::SetWindowPos(m_hwndFlashPlayerControl,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
}
Now the heart of the play movie in window code
Code: Select all
if (m_hwndFlashPlayerControl)
{
// set the scale mode
SFPCPutScaleMode info;
info.ScaleMode = 2;
::SendMessage(m_hwndFlashPlayerControl, FPCM_PUT_SCALEMODE, 0, (LPARAM)&info);
// get the character string for the movie to play
strncpy(m_url_buffer,url,1023);
m_url_buffer[1023]=0;
backslash(m_url_buffer);
// make message structure and send message to load movie
SFPCPutMovie FPCPutMovie;
FPCPutMovie.lpszBuffer = m_url_buffer;
::SendMessage(m_hwndFlashPlayerControl, FPCM_PUT_MOVIE, 0, (LPARAM)&FPCPutMovie);
// send message to play it
FPC_Play(m_hwndFlashPlayerControl);
// make it visible
::ShowWindow(m_hwndFlashPlayerControl,SW_SHOW);
// this needs to be here for FS view to be seen
::BringWindowToTop(m_hwndFlashPlayerControl);
}
Finally the code I have been using to try and handle to losing and gaining of focus in the windowProc message handling function for the WM_ACTIVATEAPP message type.
Code: Select all
case WM_ACTIVATEAPP:
if (wParam == 0)
{
// minimize flash window
FPC_Stop(pFlashWrapper->m_hwndFlashPlayerControl);
}
else
{
// restore flash window
//SFPCPlay FPCPlayMovie;
//FPCPlayMovie.hr = 1;
//::SendMessage(pFlashWrapper->m_hwndFlashPlayerControl, FPCM_PLAY, 0, (LPARAM)&FPCPlayMovie);
// make message structure and send message to load movie
//SFPCPutMovie FPCPutMovie;
//FPCPutMovie.lpszBuffer = pFlashWrapper->m_url_buffer;
//::SendMessage(pFlashWrapper->m_hwndFlashPlayerControl, FPCM_PUT_MOVIE, 0, (LPARAM)&FPCPutMovie);
// this needs to be here for FS view to be seen
//::BringWindowToTop(pFlashWrapper->m_hwndFlashPlayerControl);
// send message to play it
FPC_Play(pFlashWrapper->m_hwndFlashPlayerControl);
// make it visible
//::ShowWindow(pFlashWrapper->m_hwndFlashPlayerControl,SW_RESTORE);
}
break;
