D3D wrapper and Control dialog on vc++6

Recommended Posts

Hi every one, i just have a problem , do anybody had code for make a window app initialitating D3D with dialog or control in the window? control i mean, for example the clasic FILE-->OPEN or FILE-->SAVE AS.. that clasic windows with a D3D device ready. i just have problem with that. if anybody has code samples of that, it would be very welcome, thanks to all.

The only difference in the code should be the HWND you set in the presentation parameters. Instead of the main HWND you insert the HWND of the control which should display the D3D device.

It works best with a static control set to ownerdraw (SS_OWNERDRAW). In that case you need to call the rendering function inside WM_DRAWITEM instead of WM_PAINT though.

Ah, i think i misunderstood. Do you want to have default windows controls inside the direct3d window (buttons, dialogs) or the direct 3d window inside a dialog (not using the complete dialog)?

The first won't work easily, it's easier to use your own GUI or look at the DirectX 9.0c SDK, which has some neat GUI controls.

The second is almost the same as your code already is, but instead of calling g_d3dwrapper.init(g_hwnd, g_isWindowed, TRUE, 300, 400); in WinMain with g_hwnd you call it in WM_CREATE and use the HWND of the control. The HWND of the control can be gotten with GetDlgItem.

i put code like you said about init d3dwrapper on WM_CREATE so :



LRESULT CALLBACK WindowProcedure(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
static HINSTANCE hInstance;

switch (msg)
{
case WM_CREATE:
hInstance = ((LPCREATESTRUCT)lParam)->hInstance;
g_d3dwrapper.init(hwnd, g_isWindowed, TRUE, 300, 400); //here it is
return 0;
break;
case WM_COMMAND:
if(LOWORD(wParam) == CM_DIALOGO)
DialogBox(hInstance, "DIALOGOPRUEBAEXIT", hwnd, DlgProc);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}



BOOL CALLBACK DlgProc(HWND hDlg, UINT msg, WPARAM wParam, LPARAM lParam)
{
UINT indice;

switch (msg)
{
case WM_INITDIALOG:
SetFocus(GetDlgItem(hDlg, ID_EDIT1));
return FALSE;
case WM_COMMAND:
if(LOWORD(wParam) == IDOK)
EndDialog(hDlg, FALSE);
return TRUE;
}
return FALSE;
}




int WINAPI WinMain (HINSTANCE hThisInstance,
HINSTANCE hPrevInstance,
LPSTR lpszArgument,
int nFunsterStil)
{
HWND hwnd;
MSG mensaje;
WNDCLASSEX wincl;


wincl.hInstance = hThisInstance;
wincl.lpszClassName = "NUESTRA_CLASE";
wincl.lpfnWndProc = WindowProcedure;
wincl.style = CS_DBLCLKS;
wincl.cbSize = sizeof (WNDCLASSEX);


wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
wincl.lpszMenuName = "Menu";
wincl.cbClsExtra = 0;
wincl.cbWndExtra = 0;

wincl.hbrBackground = GetSysColorBrush(COLOR_BACKGROUND);


if(!RegisterClassEx(&wincl)) return 0;


hwnd = CreateWindowEx(
0,
"NUESTRA_CLASE",
"Ejemplo 009",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
800,
600,
HWND_DESKTOP,
NULL,
hThisInstance,
NULL
);


ShowWindow(hwnd, SW_SHOWDEFAULT);



cubo[0] = new CUBO(g_d3dwrapper.getD3DDevice(), 0.0, .0.0, 0.0);

g_d3dwrapper.clear(D3DCOLOR_XRGB(0,0,0));
g_d3dwrapper.setViewport(50,50,400,300,1);

//parametro <>1 no es el deafult
g_d3dwrapper.LookAt(0);
g_d3dwrapper.clear(D3DCOLOR_XRGB(0,0,0));



while(mensaje.message != WM_QUIT)
{
if(PeekMessage(&mensaje, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&mensaje);
DispatchMessage(&mensaje);
}
else
{

if(g_d3dwrapper.isDeviceThere())
{
g_d3dwrapper.clear(D3DCOLOR_XRGB(0,0,0));
g_d3dwrapper.beginScene();

cubo[0]->Renderizar(MX,MY,fRotx,fRoty,g_d3dwrapper.getD3DDevice());

g_d3dwrapper.endScene();

//flip el back buffer pasa a ser el front buffer
g_d3dwrapper.flip();
}
}
}


return mensaje.wParam;
}





the problem is that still didnot recognized the dialog control ("DIALOGOPRUEBAEXIT") in the callback.

Ah, i think i understand now.

You want a dialog displayed over the direct3d window. There's no special work needed for that, you could leave the wrapper.init in the WinMain then, sorry.

The second parameter for yor DialogBox call, i think it works with

DialogBox( hInstance, MAKEINTRESOURCE( DIALOGOPRUEBAEXIT ), hwnd, DlgProc );
