qt dialogs display orientation
Message 1 in thread
Hi all,
I'm developing qt software on S3c2440 system and using a 240*320 tft
sceen. My software is mainly composed of QT Dialog. I now want the
dialogs to display in a 320*240 way to make full use of the screen,
namely, I want them to rotate 90 degrees to display.
Does anybody know how to do this?
Thanks,
Scott

With Qtopia Core you should make sure that you've configured with the
transformed driver (configure -qt-gfx-transformed). You should then be able
to start your application with ./myapp -qws -display transformed:Rot90. This
will rotate all contents, not only your dialogs.
If you only want to rotate your full-screen dialogs, you could for instance
change the rotation just before the dialog is shown: Run your application
with ./myapp -qws -display transformed and before showing your dialog, do
static_cast<QTransformedScreen*>(QScreen::instance())->setTransformation(QTransformedScreen::Rot90);
This will only work within the server application (the one started with -qws).

Hi,
The Qt edition I'm using now is Qt/E 3.3.6 without Qtopia. I followed
ur direction to configure Qt with the transformed driver and there was
no error during the compilation phase. But when I tried to start my
application with ./myapp -qws -display transformed:Rot90, it failed
with the error:"transformed: driver not found".
I checked the "src/embedded" directory and found
"qgfxtransformed_qws.cpp" and "qgfxtransformed_qws.h" in it. I think
they should be compiled into the lib, but why can't Qt find this
driver?
Thanks,
Scott
