Mobile and Embedded

Hi, QquickWidget not works, the same problem... on iOS the screen goes black. EDM

Hi, IIRC you need to add @QT += gui@ to your pro file. It might look counter intuitive but currently the platform plugin containing all the low level stuff that is needed is there.

Yeah… I misread high score, I thought you wanted to provide a mean to modify some aspect of your game for testing...

Success!! I have a Qt 5.3.1 "hello world" widget app finally running on an Android simulator. In summary, do not bother with developing under Ubuntu 64-bit. I expect it could be made to work but not worth the effort to me. Qt Android Development Environment: Ubuntu Gnome 14.04 32-bit ( I failed using 64-bit Ubuntu ) Qt 5.3.1 JDK: /usr/lib/jvm/java-6-openjdk-i386 ( Do not use Java 7 ) SDK: /home/edward/android/adt-bundle-linux-x86-20140702/sdk NDK: /home/edward/android/android-ndk-r10 After installing all package updates I added one additional SDK. Eclipse->Android SDK Manager: Android 3.2 (API 13)->SDK Platform Installed Android simulators are a pain. The default settings often will not work. They are slow and cumbersome. Simulator Settings; AVD: nexus7-api-20armeabi-v7a ** Target: Android 4.4W - API Level 20 ** Android Wear ARM (aremabi-v7a) Hardware keyboard ** Skin: No Skin ** RAM: 1024 ( If I made any bigger the simulator would not run ) ** VM Heap: 32 ** Internal Storage: 200 MiB ** SD Card: Size: 1024 MiB ** Enmlation Options: (none) I thought I would try Qt 5.3.1 once again. This time when I installed, I did not try selecting Android x86 or Android armv5 as doing so seemed to break the Qt 5.3.1 installer under Ubuntu 64-bit. This may have been due to a missing 32-bit dependency under Ubuntu 64-bit. Anyway all I wanted was the default gcc and Android armv7 anyway qt-opensource-linux-x86-android-5.3.1.run I no longer needed to manually add the following build environment variable fro my Qt project: ANDROID_TARGET_ARCH There is nothing Android specific in my Qt project file. I also removed the INCLUDEPATH and LIBS from my Qt project file: @ #INCLUDEPATH += $$(ANDROID_NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/$$(ANDROID_NDK_TOOLCHAIN_VERSION)/libs/armeabi-v7a/include #LIBS += -L$$(ANDROID_NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/$$(ANDROID_NDK_TOOLCHAIN_VERSION)/libs/armeabi @ I hope this may help some other Android newbie. -Ed

[quote author="SGaist" date="1406240153"]Hi and welcome to devnet, AFAIK, no. However I'd advise you to also post that question of the interest mailing list. You'll find there Qt's developers/maintainers (this forum is more user oriented)[/quote] Thank you, SGaist, I'll try.

Nice you found out and thanks for sharing. Can you also please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi and welcome to devnet, The text has moved, search for "Rendering SVG files" and you'll find it again. However it has not changed. IIRC, If you want a full-blown svg parser you would need to use QtWebKit

Nice you found out and improved your code ! Happy coding !

Hi, IIRC since Qt for iOS is static, you need to tell qmake to link to the static multimedia plugin(s) like e.g. libqtmedia_audioengine

If you use QML/QtQuick, then just apply a rotation to the container item of your scene ( Item.rotation = 90 )

The typical approach is to instantiate an element, representing the VKB, in the application's QML code. So instead of opening a second QQuickView, the plugin provides a reusable Quick element that apps can use. The downside is of course that the application has to be aware of this and include the necessary code. Alternatively, "smart" solutions that try to figure out the QQuickWindow (e.g. through QGuiApplication::topLevelWindows) and dynamically inject some items may work too but might be much less flexible.

Regarding issue #1, call update() on the window. (it's a slot so it should be usable from qml/javascript too) Setting the clear color merely stores the values and will not trigger rendering.

It seems that on Linux you have to bind on a given interface for broadcasting packets out ot if... You can read the full story "here":http://stackoverflow.com/questions/24866807/beaglebone-black-qt-5-3-fails-to-send-datagrams-in-udp?noredirect=1#comment38645537_24866807

Either: Add you user to the tty group Delete /tmp/qtembedded-0 and restart your application

They were PNG images, I had the 'mimap' option set which made all images black..

looks like it's incorrect outputting; I resolve this to add prefix: "file://" at the begin of path.

Hey every one. I figured out the problem. For some Reason the code @this->ui->scrollArea->viewport()->setAttribute(Qt::WA_AcceptTouchEvents); QScroller::grabGesture(this->ui->scrollArea->viewport(), QScroller::TouchGesture); @ doesn’t work for QScrollArea. Then I used a class called FlickCharm [blog.qt.digia.com]. It was developed by Ariya Hidayat [blog.qt.digia.com] and it is working good now. Not satisfied I tried to use the QScroller again but this time with the parameter QScroller::LeftMouseButtonGesture that is: @QScroller::grabGesture(this->ui->scrollArea->viewport(), QScroller::LeftMouseButtonGesture);@ and…. It works for Mouse Event and for Touch Event on my Samsumg Galaxy S4. Now I’m happy because I’m just using the native class QScroller and it’s working so good. I hope to help more people in the same situation. Sincerely.

Hi and welcome to devnet, For such a low level question, you should rather go to the interest mailing list and/or the #qt IRC channel. You'll find there Qt's developers/maintainers (this forum is more user oriented)
