Simplest window example ever

[Josh]

	LRESULT CALLBACK WndProc( HWND hwnd, UINT message, WPARAM wparam, LPARAM lparam )
{
	switch( message )
	{
		case WM_DESTROY:
			PostQuitMessage( 0 ) ;
			return 0;
			break;
	}
	return DefWindowProc( hwnd, message, wparam, lparam );
}

//Create the window
WindowsWindow* window=new Window;
window->width=width;
window->height=height;
window->wndclass.cbClsExtra = 0;
window->wndclass.cbWndExtra = 0;
window->wndclass.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);
window->wndclass.hCursor = LoadCursor( NULL, IDC_ARROW );
window->wndclass.hIcon = LoadIcon( NULL, IDI_APPLICATION );
window->wndclass.lpfnWndProc = WndProc;
window->wndclass.lpszClassName = TEXT("le3_window_class");	
window->wndclass.lpszMenuName = 0;
window->wndclass.style = CS_HREDRAW|CS_VREDRAW;
RegisterClass( &window->wndclass );
window->hwnd = CreateWindowA(TEXT("le3_window_class"),TEXT("Leadwerks Engine"),WS_OVERLAPPEDWINDOW,200,200,width,height,NULL,NULL,NULL,NULL);
ShowWindow(window->hwnd,SW_SHOW);
UpdateWindow(window->hwnd);

Yeah well this is kinda shorter, and works on all platforms:

SDL_Surface* screen = NULL; 

//Set up screen
screen = SDL_SetVideoMode( 640, 480, 32, SDL_SWSURFACE );

 

Or maybe not on all, but on a nice amount of platforms:

SDL supports Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains support for AmigaOS, Dreamcast, Atari, AIX, OSF/Tru64, RISC OS, SymbianOS, and OS/2, but these are not officially supported.

I was assuming Josh was not being serious

1) I hope he was trying to funny

2) Win 32 API programming really sucks.

3) Lumooja, you realize with that code you posted there is a ton of code hidden from you that's doing basically what Josh has above.

I hate the in-parenthesis spaces coding style. Some people find it clean, it just gives me shivers.

 

Besides, wait until you create a GDK window - it's about 3 times that amount of code.

[Josh]

I mean this is the simplest code possible to create a Windows with the Win32 API. I found another example, and had to strip out tons of unnecessary code to get the result above. I thought it might be useful to anyone trying to create a basic window.

 

I want to minimize the number of external libraries the engine relies on, so SDL is not preferable.

I put a wrapper round the Win32 interface and used that to write my editor, I like developing using the win32 API. It's lean and mean and very straight forward once you get used to it.

You are a warped person Pixel

I want to minimize the number of external libraries the engine relies on, so SDL is not preferable.

That's a bad idea, since SDL brings so much good stuff in a small library:

- fastest UDP networking library

- only library which has forcefeedback for PS3 and XBOX controllers and other joysticks too

- window creating function

- keyboard reading functions

I think SDL is the only cross-platform library which is able to access the hardware on all platforms.

If you don't use SDL, you will waste a lot of time trying to implement those essential features yourself so that they work on all platforms,

and you should rather focus on the engine itself, and let the peripherial features be handled by SDL.

I don't see support for iPhone, Android, XBox, PS3, or Wii:

http://www.libsdl.org

 

In fact, 2/3 of the platforms I want to support are unsupported by SDL. Otherwise it would be a great idea.

SDL works in iPhone (because it's Mac OS X):

SDL works on Android (because it's Linux):

SDL works on XBOX360 (it's a port):

http://code.google.com/p/libsdl360x/

 

SDL works on PS3 Linux:

SDL works on PS3 (it's a port):

SDL works in Wii:

"Working" does not mean "supported". Official support is almost always quite helpful. Now, on this site, unofficial support is helpful and friendly too, but on most other sites, people will bite your head off and make you feel like a retard, just because for whatever reason, you don't quite understand something that they think is simple. So I can understand why Josh might want official support for other platforms...

Maybe LE 3 can have a plugin for whatever library you want to use, which would be useful when the user wants to use his own custom SDL and not rely on any hardcoded library in LE 3.

GLFW may also be of some interest (new release today): http://freshmeat.net/projects/glfw

You are free to implement your own drivers for device input, window creation, etc.
