Mobile and Embedded

I see. ok so what if I've compiled the C source codes on my embedded target board into exe. files, and then use Qt Creator to develop my GUI, what are the things that I link from my GUI to my target board source codes? e.g. if I create a GUI with a button, that button when clicked will run the executable file I've created on my embedded target board?

Hi, There might just be not much people on this forum that use the QtBluetooth module. In that case, there's always the interest mailing list where you can find Qt's developers/maintainers.

I fail to see the relation with QFontDatabase. Can you explain ?

@halil-sogut68 It's not clear what you want to do: do you want to uninstall your app or do you want to delete some data your app created? If you want to delete the data your app created you can use QDir and QFile. For example use http://doc.qt.io/qt-5.7/qdir.html#removeRecursively do delete a directory.

@gen1izh Thank you

thx, qt vizualizer which is pcl_vizualizer works fine with the Jetson JTK1 after the last Tegra release installed. It hardly helps get 3d reconstruction using RGB camera though. Andrey

@Sravanthi said in Port windows qt 4.8.6 (with VS2010 ) to ubuntu 12.04: 1.I want to install qt 4.8.6 in ubuntu 12.04 , what are the steps to compile ? See this 2.I have developed a windows application in qt 4.8.6 with VS2010 ,is there a way to port it to ubuntu ? Basically yes, since it's one of the main intentions of Qt to be platform independent. If you just use Qt classes of course.

Thanks for your advice! I guess i'll have to note down the portion of the vendor's framebuffer initialization code that I need next time!

@Schluchti I don't recall ever having an issue with the -Os flag in specific but then again it really depends on what you are doing and how you are coding it. :P

#include <QFontDatabase> QFontDatabase::addApplicationFont(":/fonts/OpenSans-Bold.ttf"); Add font in Qt Resource, to build in executable. http://doc.qt.io/qt-5/resources.html

Thanks for your reply. Best Regards Marek

@gen1izh what if you try a little example with Qt 5.5.1 to see if it works for you?

@SGaist i am not sure about this...for temporary solution i have to reboot my device after 3 hour.. ..

Yeah manually using command line I am able to transfer the files to mobile. I am using Bluez5 bluetooth stack. Do I need to modify something in the code for that?

Thank you, I will look into this further,

Hello. See example: Qt\Examples\Qt-5.7\androidextras\notification Qt\Examples\Qt-5.7\androidextras\notification\android-sources\src\org\qtproject\example\notification\NotificationClient.java This class extends public class NotificationClient extends org.qtproject.qt5.android.bindings.QtActivity In other words this is your activity , add BroadcastReceiver there. Check that there is a change in AndroidManifest.xml android:name="org.qtproject.example.notification.NotificationClient" Where this class becomes its main activity. I have helped .
