Calling QML functions from C++

[neda]

Thank you,
I have this code in "MySerialPort" class:

void MySerialPort::readData()
{
	QByteArray data = serial->readAll();
	if(data[0]=='0') // For example
		Show qml dialog
	if(data[1]=='1') // For example
	   disable GroupBox	
 
...
...
}

void MySerialPort::readData()
{
	QByteArray data = serial->readAll();
	if(data[0]=='0') // For example
		Show qml dialog
	if(data[1]=='1') // For example
	   disable GroupBox	

...
...
}

To copy to clipboard, switch view to plain text mode 

How can I handled this code on the QML side?

The usual way is to have a property on a C++ object that is exposed to QML.
I think we've already discussed this before.

In this case maybe an int or enum property.

QML then reacts to changes of that property the usual way, e.g. via property bindings.

Or you emit signals and handle these in QML, e.g. using a Connection element
