How to integrate SDL as a child Window

Mine · November 15, 2007, 7:35am

Hi All,
I’m using SDL on Windows XP. And I want to use it as a child window in
my application.
There is a new window created by SetVideoMode, is there any way to set
it as my application’s child window instead of a stand alone window? That is
to say, I want it to have no task bar, no title bar (this is OK by
SDL_NOFRAME), when the focus is in SDL window, the application’s main
windows is also focused.
Is there a way to implement that?–
Mine

Short answer is; no.

It would be very useful but SDL 1.2 can’t do this; fingers crossed for 1.3…> ----- Original Message -----

Wow… I came here to ask that same question, and this was at the top of
the list… What a coincidence. O_O

Anyway, Mr. Byard, you might be wrong:
http://www.polplex.co.uk/~tigger/sdl/

And I say “might” because I tried a modified (non-C++) version and it
crashes after the first call to SDL_BlitSurface… Here’s my code:

(Note that I did put error checks on stuff like SDL_CreateRGBSurface, I
just removed it to make the code shorter)

------------------- int bmsize; HDC dc = GetDC(g_WindowHandle); BITMAPINFO *bmi; BITMAPINFOHEADER bh; WNDCLASSEX wc;

/* Create the window */

wc.cbSize		= sizeof(WNDCLASSEX);
wc.style		 = 0;
wc.lpfnWndProc   = WndProc;

wc.lpszMenuName  = NULL;
wc.lpszClassName = "scorchWindowClass";
wc.hIconSm	   = LoadIcon(NULL, IDI_APPLICATION);

g_WindowHandle = CreateWindowEx(
	WS_EX_CLIENTEDGE,
	"scorchWindowclass",
	"YASEC = Yet Another Scorched Earth Clone",
	WS_OVERLAPPEDWINDOW,
	CW_USEDEFAULT, CW_USEDEFAULT, a_Width, a_Height,
	NULL, NULL, a_hInstance, NULL);

ShowWindow(g_WindowHandle, a_CmdShow);
UpdateWindow(g_WindowHandle);

/* Create the surface */
g_Screen =
	SDL_CreateRGBSurface(SDL_SWSURFACE, a_Width, a_Height, SCR_DEPTH, 0,

0, 0, 0);

/* Get width and height */
g_ScreenWidth = g_Screen->w;
g_ScreenHeight = g_Screen->h;

bmsize = sizeof(BITMAPINFO);

if(g_Screen->format->palette)
{
	bmsize += g_Screen->format->palette->ncolors *
		sizeof(RGBQUAD);
}
else
{
	bmsize += 3*sizeof(DWORD);
}

bmi = (BITMAPINFO*)malloc(bmsize);
/* Clear struct */
memset((void*)&bh, 0, sizeof(BITMAPINFOHEADER));

/* Initialize struct */
bh.biSize = sizeof(BITMAPINFOHEADER);
bh.biWidth = g_Screen->w;
bh.biHeight = -g_Screen->h;	/* -ve for topdown bitmap */
bh.biPlanes = 1;
bh.biSizeImage = g_Screen->h * g_Screen->pitch;
bh.biXPelsPerMeter = 0;
bh.biYPelsPerMeter = 0;
bh.biClrUsed = 0;
bh.biClrImportant = 0;
bh.biBitCount = g_Screen->format->BitsPerPixel;
bh.biCompression = BI_BITFIELDS;

bmi->bmiHeader=bh;

((Uint32*)bmi->bmiColors)[0] = g_Screen->format->Rmask;
((Uint32*)bmi->bmiColors)[1] = g_Screen->format->Gmask;
((Uint32*)bmi->bmiColors)[2] = g_Screen->format->Bmask;

g_WindowBitmap = CreateDIBSection(dc, bmi, DIB_RGB_COLORS,
	(void **)(&g_Screen->pixels), NULL, 0);

/* Free memory */
free(bmi);
ReleaseDC(g_WindowHandle, dc);

return 0;

-------------------

Any ideas? Thanks!

Sorry for double posting, I just realized that I forgot to say I did
initialize SDL somewhere else before the call to that code. Embarrass
