i want to use only one window. when it starts the program it opens a console and then another window. how do i keep it to one window. i looked in docs and it said win_set_window(HWND wnd); ... but im not using win32 in the program and i cant use the HWND. how do i get it to only one window outside of win32.

ok it works. but ive got one more question. how can i stop it from saying the thing about "closing the program my cause errors" when i click the X.

ok i cant find set_close_button_callback(). all i see is set_window_close_hook() and set_window_close_button().

[edit]i figured out that its set_window_close_hook() that im looking for but i dont know what i need to enter as an argument for it to close without asking for the "loss of data" thing.

Aren't the set_windows_close_XXX functions depricated?

How 'bout int set_close_button_callback(void (*proc)(void)); then - that one isn't deprecated, right?

they didn't work as expected. By default, the closebutton handler would close the Allegro window from a callback function, which was something the docs explicidly told you not to do.
Hence, a better alternative was introduced, which makes the old broken functions obsolete. However, some programs used these functions, and in order not to break old sourecode, backward comptaibility inline functions were added.

Disable the close button unless the user registers a callback function (using set_close_button_callback()), because it doesn't do anything useful if s/he doesn't.

Frankly, it looks more like a bugfix to me, since Allegro's original handler was broken...

Post some code, please.
It should look something like this:

void my_callback(void)
{
   //do some stuff
}

...


set_close_button_callback(my_callback);

It should be:
<code>
#include <allegro.h>

void func_name(void)
{
// do something
}

int main()
{
allegro_init();
install_keyboard();
set_color_depth(16);
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0);
set_window_close_hook(func_name);
readkey();
return 0;
} END_OF_MAIN();

ok fine ... i got it.
