Qt App rotation [solved]
-
Ok, then the Qt you are using might have not been built with the -gfx-transformed
-
How can I add?
I compiled the quake with the .configure with the flag: -qt-gfx-transformed
And the application is using that quake. -
Did you copy the resulting libs to your beagleboard ?
-
No, which libraries should I copy and to where?
-
If you don't have size constraints you can copy the QtEmbedded-4.X.X folder to the same place on the board (you can trim it down later once you have your application up and running)
-
I'm sorry, I don't understand... I have the qt-everywhere-opensource-src-4.6.2 directory where I compiled the qmake. and all the outputs are located in an out directory I chose.
In the out directory are subdirectories:
bin demos examples include lib mkspecs plugins translations
and in bin there is the qmake Im using in the Qt creator.
what should I copy and where to? -
Copy the lib and plugins content on your target filesystem. Generally I let Qt install the files in the default location which is /usr/local/Trolltech/QtEmbedded-4.X.X so on the target I copy the files in the same dir.
-
Oh my god! I used generic Qt libraries for the beagleboard and not the ones I compiled...
Thank You SO MUCH!!!!!! It's working! -
Can I ask you another question about screen rotation?
I tried to rotate the screen with:
echo 1 > /sys/class/graphics/fbcon/rotate
and the frame buffer is rotating but when i launch the Qt app it doesn't rotate...
Do you know if it's possible to rotate it that way as well?.. :)Again, Thank you! :)
-
You're welcome :)
Did you start the application with the transformed stuff ?
-
I mean to rotate the whole frame buffer and launch the app.
When I tried to do this with the rotate file I mentioned before the OS rotates but when I launch the Qt app (without the display transformed) it's still straight.. It doesn't affect the Qt app. -
You can try (maybe using ssh) to rotate the whole frame buffer after the application launch
-
Tried that already and it still launches straight.. :/
(The frame buffer is rotated but the qt app on top is straight) -
And the transform parameter ? Doesn't have any effect ?
-
Doesn't effect at all.. the Qt app ignores the frame buffer rotation completely...
-
Might be a bug then... Did you check the "bug report system":http://bugreports.qt-project.org/issues/ to see if something similar has already been reported ?
-
Did now.. couldn't find anything about it..
-
Another test I can think of is to build your QtEmbedded for x86 with the same options and qfvb additionally and try to start your program with the same command line options directing the output to qvfb
-
Good idea, but I think the transposed is good enough for me now.. maybe i'll go back to that later on.
Thanks alot! :) -
You're welcome !
If you have everything working now, could you update the thread title prepending [solved] ? So other forum users may know a solution has been found :)
