Re: [AD] [GUI] Error using MSG_IDLE

[Javier González <xaviergonz@xxxxxxxxxx>]

here is a very simple program that you can test what i mean. if you comment
the sendmessage line it will work

---
#include <allegro.h>

int my_proc(int msg, DIALOG *d, int c) {
  if (msg == MSG_IDLE) {
    SEND_MESSAGE(active_dialog + 0, MSG_DRAW, 0);
  }
  return D_O_K;
}


int main(void) {
  static DIALOG dialog[] = {
    /* (dialog proc)(x)(y)(w)(h)(fg)(bg)(key)(flags)(d1)(d2)(dp)(dp2)(dp3)
    { d_box_proc, 0, 20, 640, 35, 15, 15, 0, 0, 0, 0, NULL, NULL, NULL },
    { my_proc, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL, NULL, NULL },
    { NULL, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL, NULL, NULL }
  };


  allegro_init();
  install_keyboard();
  install_timer();
  install_mouse();
  set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0);
  do_dialog(dialog, -1);
  allegro_exit();
}
END_OF_MAIN();

I know it doesnt check many parameters, but it's just an example
compile it with the send_message line commented and uncommented
