Working with Q_PROPERTY and exposing the back end to the front end.

[RobM]

So when I create a variable and expose it to the front end like so:

        Q_PROPERTY(bool             connected                        READ connected                         WRITE setConnected              NOTIFY connectedChanged)

I can call the setConnected from the front end or does it automatically get called when I call connected?

[RobM]

I believe the answer is that it calls that for me. For instance:

object.connected = true

is going to call the setConnected (setter) of the Q_PROPERTY. Whereas, saying something like:

if(object.connected === true)

is going to call connected (getter) of the Q_PROPERTY, correct? In other words, unless I plan on changing the value of connected from QML then I do not need a WRITE.

Thanks for the correction @LeLev

yes that is correct, if you don't have the WRITE method then it will become like a read-only property
