Then study the gstreamer implementation for example and start from there.

The pattern is to have a "session class" that does the work and then provide all the interfaces you support that will be using said session class.

@SGaist Your comment was very helpful. I checked the contents by printing them and saw that when I called the process, the file was still being written (since I write a JSON file from the GUI). So I added one more line QFile.close() and now the python script is called only after JSON gets written from the GUI. Now it is running fine.

Tricky one !

Thanks for sharing :)

@rahulch_pp Try to comment the line 18 of main.qml " animationOptions: ChartView.AllAnimations".
It seems to be buggy from Qt5.12 (and also Qt5.12.1)

@Mathan-M
as i said when it displays a row, the model is correctly applied, so there must be something wrong with your model implementation.

@Mathan-M said in Signal emit Issue - Listview is not showing full list:

Do we have any link/tutorials to follow or how to bind the value from CPP to qml.

Here you go.

@Mathan-M
Following Java code can be used (Can be easily used from JNI if needed)

// android.os.StatFs StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath()); long bytesAvailable = (long)stat.getBlockSize() *(long)stat.getBlockCount();

Hi,

Maybe a silly question but are you sure that OpenCV is properly installed in opencvArm ?

@ars1614 Yes they are converted automatically.

@jsulm I meant to change some configurations, if there are some, and fasten the compilation.

So if I choose the external resources step, is it feasible to do the following steps:

Can I integrate the rcc command that I have to execute manually in terminal, somehow to the make step of the application, so that it is executed automatically?

If I achieve the upper step, can I detect, whether the qrc was changed a new rcc compilation is necessary?

Aliasing problem ?

My apologies, I will create a new thread. Thanks for all your help! (and putting up with my stuff :) )

Thank you for your answer but I have find my mistake.
The property should be : property variant myObject: MyLib.monObject

@antemort First check if that QML contains no error. Secondly you need to findChild in the rootObject

QQuickItem *rootItem = view.rootObject(); //root item in QML QQuickItem *child = parent->findChild<QQuickItem*>("childobjectname"); //find child of that root object using its objectName child->setProperty("angle1", 160); //set property angle1 to 160

Hi and welcome to devnet,

What version of Qt are you using ? What exact error message did you get ?
