Mobile and Embedded

Hi, Are you using Qt 5.3 ? Have a look at "MenuBarStyle":http://qt-project.org/doc/qt-5/qml-qtquick-controls-styles-menubarstyle.html. It works on Ubuntu 14.04. But I've not tested on Android Device.

Hi thanks for your help... sorry... it's QT_ARCH_ARM and not Q_ARCH_ARM... in qt4 it is checked in src/corelib/global/qglobal.h... ... #elif defined(QT_NO_FPU) || defined(QT_ARCH_ARM) || defined(QT_ARCH_WINDOWSCE) || defined(QT_ARCH_SYMBIAN) ... but you are right, it seems never defined...

Found the solution to my problem. The android:name in the <activity> section of the manifest should be changed to my java Class. uk.me.samaria.flickrshare.AndroidFunctions instead of org.qtproject.qt5.android.bindings.QtActivity Now that, I am able to share text, onward to share an Image and see if that works.

Decided to use QQmlApplicationEngine. topic closed.

If using linuxfb, i have to call as root. A normal user is (without modification of udev-rules) not able to open /dev/fbX. So yes: i'm not able to get inputs even running as root.

First, sorry for late answer. In fact I knew that, but it didn't answered me, because I was trying to achieve these manipulations for each touchs (and not only the first one), and not only move manipulation. I was working on collaborative apps, where users must manipulate the QGraphicsItems independently. I had a project changement, so I don't need this anymore, but if someone created some default QGraphicsItems with touch manipulation enabled, I'll be pleased to know ! If I do something like this in the future, I'll come post this here :)

@#define COP_CHANNEL_NAME "WatchdogChannel"@ Yes, it will be destroyed. I've implement this also as a class member, but it doesn't change anything. It is strange.

The bug report is "here":https://bugreports.qt-project.org/browse/QTBUG-39978

You're welcome ! Since you have it working now, please update the thread title prepending [solved] so that other forum users may know a solution has been found :)

I managed to get rid of the freezing gui. The trick is to make the signal slot connection in c++, when you have gui and logic in seperat threads. The Connections QML element and the someid.signal.connect... thing dont work here and for some reason it seems that both ends in an "Direct Connection" instead of the wanted "Queued Connection. => From C++ it works for me ... and be aware to make both direktions in c++ qml slot < > c++ signal and c++ slot < >qml signal! Snippet from my code: @QObject* root=dynamic_cast<QObject*>(m_view->rootObject()); // cast needed because of private inharitance + note QQuickItem include is needed QObject* obj; if(root){ obj=root->findChild<QObject*>("winlog"); if(obj){ qDebug()<<"found winlog and connecting signal"; QObject::connect(obj,SIGNAL(connectToDb(QString,QString)),this,SLOT(connect(QString,QString))); QObject::connect(m_man->getDatabase(),SIGNAL(connectedChanged()),obj,SLOT(onConnectToDbChanged())); }else{ qDebug()<<"didn't found winlog for connecting signal"; } }@

I did some research and found that this RGB color is getting changed to BRG color. (not BGR). It is because of the little endian issue. Powerpc is big endian and frame buffer is little endian. I have not got any solution to this problem. Will update the thread once i get it. If anybody got similar issues then please reply.

ltr6, thank you for that hint, it works perfectly!

Is this valid for Qt5.x also?? I am also facing the Color issue after cross compiling the QT from source code for powerpc. RGB is appearing as BRG.

bq. what is the purpose of this radio and declartive radio? May be it works for other devices.

Radium1988, although I've been programming for a long time but my experience in Qt is just 2 months. So I can only reply to some of your questions. Maybe someone more experienced in Qt will read this thread and will answer your other questions. bq. 1. Are some of the examples not compatible with Android? If yes, what makes a project not compatible with Android? It is quite possible. Some components have not been ported to Android yet (Qt have been supporting Android since the 5th version). For example positioning have been working on Android since 5.3 version. bq. 3. Widgets in designer for Android seem too limited and few, are there any importable third party widgets more similar to native android for Qt Creator? I don't know. I did not find. For now I am using original Qt widgets and writting my own widgets. bq. 5. With each Run, even when the last AVD is still open, a new instance of AVD will start. how can I prevent this and just use the last AVD? I have it is different. If one AVD is already open, then new instance does not start. bq. However I checked the APK files sizes on my phone, and they were between 8 to 28 megabytes!! I created a new empty project and deployed it, but even the empty project is 7 megabytes in size! Are these debug APKs that are fat and big? APK is zip archive. There are Qt libraries, Ministro and other java classes (+ gdb server for debug and maybe additional plugins) in archive. Unfortunately I can't give more detailed answers.
