Mobile and Embedded

Thank you, I will take a look.

Thanks seyed, your solution is working, but i had to modify it slightly as it was giving me a compile error on this line QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;"); So I changed it with this: QAndroidJniObject activity = QtAndroid::androidActivity(); And it is working perfectly Thanks everybody for the help

You're welcome :) But… Did you find the answer you were looking for ?

Are you trying to set a default font to your Qt application ? Then try this, int loadedFontID = QFontDatabase::addApplicationFont("<Your custom font pathname (TTF/PFA/PFB/BDF/QPF)>"); QStringList loadedFontFamilies = QFontDatabase::applicationFontFamilies(loadedFontID); fontName = loadedFontFamilies.value(0); QFont font; font.setFamily(fontName); app.setFont(font);

Thanks for the answers Sam!

Dangerous file name indeed ! Glad you found out and thanks for sharing :)

Hi and welcome to devnet, Are you using PyQt or PySide ? AFAIK, the version of Qt has no influence with your problem. You're likely getting an invalid value for the geometry property from your QSettings object. Did you save that property once ?

if I pair my bluetooth device from raspian. btscanner shows they were paired. But when I try to connect it it gives a new error. :) qt.bluetooth.bluez: void QBluetoothSocketPrivate::_q_readNotify() 15 error: -1 "Resource temporarily unavailable" QT, Linux, Raspberry have lots of problems for every steps:) If someone can solve problem above, I have this problem in the next step:)

What did you change ?

@SGaist Thanks.

Hi, there are 2 possible cases: If you are sure that void DistanceThread::run() exit after first iteration then you are setting "flagforbreak" or "diststop" in between. So could you please check the slots of those signals which you are emitting? (May be the flag set from there). DistanceThread::run() is still executing but your conditions (i saw complex nested "If"s there :) ) may not meet anytime.(Hope U will debug it ensure that. Regards, Rajeesh Raveendran

I moved to QT 5.5 and it works prefectly when i have another process triggered the oxmplayer which it is running underneath of my applicatioin. thanks.

@SGaist ,Thank you, I call to java native via jni, and it work for me.

You can set the sizePolicy of each element in a layout. Typically a button has a fixed vertical size and an expanding horizontal size (dont get confused with "minimum" and "expanding" size policy). Maybe it is useful to take the Qt creator and create a simple application and play around with layouts...

I think you need give more output error,

As I know, you can't do it in Qt C++, you need using JNI to call from C++ to Java and vice versa, Here is link to start http://doc.qt.io/qt-5/android-support.html
