Mobile and Embedded

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.

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)

Ok, I got it. There was a problem on write permission about the location on where saving the photo taken by camera. On some devices, everything goes well, on others the camera will fails to write on disk and instead of given an error, it will freeze the app :-( My mistake, because I used an hard-coded path and I didn't notice it :-(

Hi and welcome to devnet, Boot2Qt being a commercial product you should contact Digia directly about that matter

Now i have found the following method: create your own AndroidManifest file in the deployment setting of your project then add to the project .pro file: @ android { addon.files = example.txt exampledir addon.path = $$[PWD]/assets INSTALLS += addon } @ run qmake, build and deploy your project Regards l.f.

You're welcome ! Don't be afraid to ask question :) Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Does Qt 5.3.1 widget apps work with Android? Should roll-back to Qt 5.2.1? The messages following the exception refer to QtActivity. Is that a useful clue or just means it crashed shortly after starting? -Ed

Hi, Have you confirmed that your beaglebone image includes the GLES2/gl2.h file? If so, check your QMAKE_INCDIR_OPENGL path, perhaps your missing the final directory? Similar to this (for another embedded) @QMAKE_INCDIR_EGL = $${QMAKE_PATH}/usr/include/EGL QMAKE_LIBDIR_EGL = $${QMAKE_PATH}/usr/lib QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_PATH}/usr/include/GLES2 QMAKE_LIBDIR_OPENGL_ES2 = $${QMAKE_PATH}/cubie-rootfs/usr/lib@

Seems solved by disabling glibc, taken from this bug report "bug":https://bugzilla.redhat.com/show_bug.cgi?id=579838

Thank you TRudolph, that is exactly what I was looking for. Apparently my search requests didn't contain the right words. Regards, Greg

take a look to this, it worked to me http://qt-project.org/forums/viewthread/42365/ Now i can use qtquick 2 to develop eglfs app and use my touch screen via tslib

[quote author="SGaist" date="1405668675"]Hi, Doesn't Navit use GTK+/SDL for it's UI ? You should rather ask this question on their forum[/quote] Hi, Thanks for the reply. I think by default Navit is using "internal gui". I got this from navit.xml, "<gui type="internal" enabled="yes">". I found a link "here":http://wiki.navit-project.org/index.php/QML_GUI, and they are using "qml gui" instead of internal gui. I tried this, but i doesn't work for me. May be i will try in their forum to. Regards Ansif
