ObjectCounter | android application to count objects | Computer Vision library

Qt::WA_X11NetWmWindowTypeDesktop is a Qt::WidgetAttribute so it only makes sense for the QWidget and it seems that the OP understands it because in its attempt it uses a QMainWindow but the problem is that the QMainWindow does not show the QML so that is not the solution.

The idea is to have a QWidget where the QML is so in this case there are 2 possible solutions:

1. Set visible: false in ApplicationWindow and use QWidget::createWindowContainer():

Your code and the error message is not consistent. I'm going to assume that in this error:

Bidning: 'IncrementCommand property not found on AppDemo.Models.SampleObject, target property XamarinForms.ImageButtonCommand'

SampleObject is now named SampleModel.

Like Jason pointed out in a comment, the binding context for each item in your list is different than the binding context for the whole page. Whenever you use a list, the binding context of each item will be scoped to the item in that cell.

To be able to reach something outside of that, you will have to use a reference. First, give a name to your ListView like this: .

Then, for your ImageButton, change the Command to be this:

By adding the source and referencing the ListView, we now scope the binding to whatever we specify in Path. So we suddenly can access the properties of the ListView and access its BindingContext (being the SampleModel) and inside that context access the command we are after, in this case, IncrementCommand.

Does that make sense?

It turned out it is because of i left antialias default as context attributes which seems "true". Can't believe i did not notice.

This code worked for me

Welcome!

The problem with ~objectCount() is essentially that it says "delete the objectCount object"... and the compiler says "which one?" If you don't somehow keep track of the objects you create, you're probably memory-leaking those objects.

Instead of directly calling the constructor and destructor, I'd recommend using the new and delete keywords. Those operate on objectCount pointers, so for example, you could have code like:
