Hello,

i learn how events are coding on allegro 5 and i see that kind of event :

ALLEGRO_EVENT_DISPLAY_ORIENTATION

and property of display :
event.display.orientation

Contains one of the following values:

ALLEGRO_DISPLAY_ORIENTATION_0_DEGREES
ALLEGRO_DISPLAY_ORIENTATION_90_DEGREES
ALLEGRO_DISPLAY_ORIENTATION_180_DEGREES
ALLEGRO_DISPLAY_ORIENTATION_270_DEGREES
ALLEGRO_DISPLAY_ORIENTATION_FACE_UP
ALLEGRO_DISPLAY_ORIENTATION_FACE_DOWN

how is it possible to rotate an allegro display ?
(i am under visual studio 2013 and windows 8.)

Thank you.

The events are intended to catch the rotation of the display by the undelying operative system, tipically on mobile platforms (Android & iOS) I presume, even thou it's possible to rotate the display also on Windows I currently don't know if Allegro catches such events on this platform.

I don't think (if I understood you corrcetly) that there's a method in Allegro API that lets YOU change the orientation.

Yes, those events are if the device itself detected a physical orientation change.

If you want to rotate your drawing, use ALLEGRO_TRANSFORM s.

thank you very much, Allegro is a wonderful library full of surprises !
