Screen Rotation - qt embedded 4.5

Hi all,

I'm a beginner in Qt so I would like to ask you advices on how to rotate the screen in qt embedded 4.5.


I'm using the Linux framebuffer driver and on reading this doc

http://doc.trolltech.com/4.5/qt-embe...anagement.html

I understand that rotation is only avaiable for Transformed driver.


I try to do rotation via sw. I noticed that in doc

http://doc.trolltech.com/4.5/qscreen.html

there is the definition of the static function

void QWSDisplay::setTransformation ( int transformation, int screenNo = -1 )

but when I call it in main function,

Code:

---

QWSDisplay::setTransformation(QTransformedScreen::Rot90, 0);

---

I obtain the error

error: incomplete type 'QWSDisplay' used in nested name specifier.


Could you give me some suggestions?

Thanks in advance

Beppe

That error generally means the class is not fully defined, which means you need to include the correct header before you use it.

Thanks andy.

At the end I found the solution.

I recompiled qt-embedded with the option

-qt-gfx-transformed

and when I launch the application I use the command

./myapp -qws -display transformed:Rot90
