Is there some support for buttons in allegro? I mean like menu buttons so that I wouldn`t have to check myself if mouse is clicked and propper frame is on top etc.

Tomek, are you talking about the buttons that are found in the allegro examples/exgui example file?

Yes, thanks. It seems to cover all I`ll need. I just wish it would look that complicated (the code)...

EDIT:
I`ve tried to display a single button using the code from that example and I failed.
Here`s the code:

1 
2extern int info1(void);
3 
4int my_button_proc(int msg, DIALOG *d, int c)
5{
6   int ret = d_button_proc(msg, d, c);
7   if (ret == D_CLOSE && d->dp3)
8      return ((int (*)(void))d->dp3)();
9   return ret;
10}
11 
12void Manager::MainMenu(){
13DIALOG the_dialog[] ={
14    { d_clear_proc,        0,   0,    0,    0,   0,  0,    0,      0,       0,   0,    NULL,                   NULL, NULL  },
15    { my_button_proc,    400, 150,  160,   20,   0,  0,  'i', D_EXIT,   0,   0,    "&Info",  NULL, (void *)info1 },
16     { NULL,                0,   0,    0,    0,   0,  0,    0,      0,       0,   0,    NULL,                   NULL, NULL  }
17}; //(*)
18    do_dialog(the_dialog, -1);
19}
20 
21int info1(void) { allegro_message("asasas");}

In line (*) I get an error: invalid conversion from `const void*' to `void*'

Try to replace (void *)info1 by (const void*)info1.

I`ve done that and this way I get the same error in the same place, except that I get it twice.
I`ve tried to make a rebuild (deleted all non .cpp and non .h files from the dir) and it didn`t help.
