Mobile and Embedded

Finally got around to this again. Awesome suggestion! It worked! Not sure why QGuiApplication::quit() didn't work, but I'm super happy to be done with it. :)

Ok I have used std:thread...thanks

visual basic and c++ are the best pc programs that .......... http://www.soran.edu.iq

Thanks for your suggestions, but that did not help. Now I've tested the new Qt 5.3 version on a real Samsung Galaxy S3 and it works really well! I'm quite impressed to see such good results in these early developments of Qt in Android. With the new version I realised that my OpenGL shader program did not compile under android as I was using floating points without the ".0". Eg: @ vec3 light_Position = vec3(0,0,0); // wrong vec3 light_Position = vec3(0.0,0.0,0.0); // right@ Before I was not getting any complaints about my shader program from the android device. I found a couple problems: 1- The virtual android devices do not work with OpenGL (OpenGL cannot be initialised). I had to test with the real device. Every compile test also takes quite a while... 2- If I use a toolbar located at the top, the OpenGL screen is not shifted accordingly: the top screen is blocked and I have a dark spot at the bottom. However, a quick fix is to place the toolbar is at the bottom. My program uses OpenGL mixed with Widgets as in "THIS EXAMPLE":http://doc.qt.digia.com/qq/qq26-openglcanvas.html I do not know if this can have an effect. Also the toolbar does not work very well when a drop down button is pressed. Still... I'm quite impressed with the new version :)

"You indeed need to check that yourself (ask the author, maybe?), but if they are using QPainter or the scenegraph to paint the plot, then it is most probably compatible with Android." Yes, I sent e-mail to the author, now I'm also looking for other libraries for real time plot. For now I found nothing . For the 3d OpenGL ES are compatible with android, but i think is more difficult to move a rigged model with OpenGL ES, because online there aren't a lot of tutorials :/

Hi :) I'm looking for an other method to do what I say in the first post :) With qt which 3d library can I use that is compatible with android and let me move a part of my rigged model's body ?

Can you help me with this post? http://qt-project.org/forums/viewthread/43131/

Hi, thanks for reply. In the end I used the low level ::read() and ::write() commands found in fcntl.h. The only major issue I had with this was turning off the serial ports canonical mode which appeared to be on by default with the following: @ //get current settings termios tc; ::tcgetattr(fd, &tc); //canonical mode - off tc.c_lflag &= ~ICANON; //save current settings ::tcsetattr(fd, 0, &tc);@ ...again thanks for comments.

Hi musimbate, I got the same problem with you. How about your problem? have you solve it yet? Thank you in advance Best regards,

Oh i forgot to mention that this worked for Qt 5.1.1. I was not able to build Qt 5.2 or 5.3 for my device. The message was: "Add the datastream version for this Qt version" which could be a hint that my compiler is too old, i'm not sure about that and version 5.1.1 is sufficient for now.

Thank you! I did see that example but I just need a terminal program, not a game. I suppose I could study how it is done. I did look at Qt Quick in general and have some questions. I think I will make another thread for them. Update: here it is: http://qt-project.org/forums/viewthread/43090/

OK, things runs correctly, I've solved this problem!

I also struggled with the "Buildfile: build.xml does not exist!". It was because I only installed openjdk-7-jre. openjdk-7-jdk is also required. Qt Creator kept saying "/usr/lib/jvm/java-7-openjdk-i386" was invalid for the JDK location. I guess it looks for something that openjdk-7-jdk puts in the /usr/lib/jvm/java-7-openjdk-i386. After installing openjdk-7-jdk, Qt Creator was happy with the location. (Using Kubuntu 14.04, JAVA_HOME set in /etc/enviroment)

If the libs used by the backend (and the hardware of course) provides a mean to do it then I would say it's a missing feature.

Oh, nice! Thankyou :)
