Hi and welcome to devnet, You should rather ask this on the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented

Hi, You should rather ask this question on the "android-development":http://lists.qt-project.org/mailman/listinfo/android-development You'll find there the Android port's developers/maintainers This forum is more user oriented

Thanks Sgaist, I have a doubt before posting on the mailing list. I am real noob about iOS things

Now it works! Thank you very much, man!

Thank you! I successfully compiled the qtbase. But when I compile other modules, there are some errors. When I compile qtjsbackend,the error is as followed @In file included from ../3rdparty/v8/src/v8.h:58:0, from ../3rdparty/v8/src/accessors.cc:28: ../3rdparty/v8/src/v8globals.h:434:1: error: expected identifier before ‘<<’ token <<<<<<< HEAD ^ ../3rdparty/v8/src/v8globals.h:434:1: error: expected ‘}’ before ‘<<’ token ../3rdparty/v8/src/v8globals.h:434:1: error: expected unqualified-id before ‘<<’ token ../3rdparty/v8/src/v8globals.h:578:3: error: expected declaration before ‘}’ token } } // namespace v8::internal ^ make[2]: *** [.obj/accessors.o] error 1 make[2]: *** waiting the uncompleted task....

thank you for reply. Examples from Vivante load core of CPU more less then Qt application - 5...10%. If I use ListView and scroll content by finger "left-rigth" - core CPU loaded by render thread even more (upto 70% and more)... So is it normally, or it is wrong use compiler options, or something else? P.S If I use qml animation, power consumption is increases +5 watt. Explicitly GPU is activated. But the CPU core is loaded very hardly too.

I had the sam problem and accidentally found acceptable solution? this will produce resizeable window without title: @w->setWindowFlags(Qt::Tool|Qt::CustomizeWindowHint);@

I'm found only this "document":https://qt.gitorious.org/qt/qtconnectivity/commit/5c87c1e0e26bee77bf02459df884435f8c48e0f2#src/bluetooth/doc/src/bluetooth-overview.qdoc.

I think that the function will be the following: QString DeviceAdrHandlingOUT::read_shared_Memory() { QSharedMemory sharedMemory("DeviceOUT"); // <== MY CHANGE if(!sharedMemory.attach()) { qDebug() << "can't attach" << sharedMemory.errorString(); } QBuffer buffer; QDataStream in(&buffer); QString str; sharedMemory.lock(); buffer.setData((char*)sharedMemory.constData(), sharedMemory.size()); buffer.open(QBuffer::ReadOnly); in >> str; sharedMemory.unlock(); sharedMemory.detach(); return str; }

Welcome to the forum. I will send you the program shortly.

Good question, would like to know aswell!

The solution is call the java class from qt c++ program using JNI class and the java class is the following: @// // Next72Utility.java // package org.qtproject.example.Chronometer; import android.content.Context; import android.app.Activity; import android.view.WindowManager; import android.view.WindowManager.LayoutParams; import android.os.Bundle; public class Next72Utility extends org.qtproject.qt5.android.bindings.QtActivity { public static Next72Utility m_istance; public Next72Utility() { m_istance = this; } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); } }@

There's no code involved, you need to edit that file

That won't work, you can't run x86 binaries on ARM. You first need to cross-compile your application.

Hi, I forgot to post an update here regarding my qt5 wince 6 experience. Finally I've got a successful build small build of qt5 for windows ce 6 built with VS2008. But as you can see in the configure command there are many missing components even the whole gui module. The following configure command enabled me to build qt5: @ configure -platform win32-msvc2008 -xplatform wince60embedded-armv4i-msvc2008 -opensource -nomake examples -no-compile-examples -no-accessibility -no-native-gestures -no-gui -no-opengl -no-icu -skip activeqt -skip winextras -skip declarative -skip location -confirm-license @ Currently it is okay for us to stay without the gui module in a wince environment since Core, JSON, XML etc. module works fine. The build with the gui modules currently stucks with the following error: @ qwindowsdialoghelpers.cpp qwindowsdialoghelpers.cpp(804) : error C2504: 'IFileDialogEvents': Base class undefined @ Next step is to get the qtmultimedia module working under wince. With the above described configure, the build system doesn't build the multimedia module. Does anybody know how to build the multimedia module for wince? Is there a way for just building the multimedia module without doing a new whole qt build?
