Hi
Thanks for your reply.
I am having some issues with getting this to work
in my class declaration I have
@
Q_PROPERTY (bool running READ running WRITE setRunning NOTIFY runningChanged)
.
.
.
private slots:
void onRunningChanged();
signals:
void runningChanged();@
In another class I have
@
connect(m_currentSession,&Session::runningChanged,this,&Manager::onRunningChanged);
@But when the property changes my slot is not called
Am I misunderstanding how it is supposed to work?
Thanks

You need to emit the signal yourself in your C++ code.

Hi, these has nothing to do with the macro Q_PROPERTY.
You should always emit the the signal runningChanged by yourself when the property changed, for exmple, in your setRunning() function.

Hi,
To add to my fellows, the standard construct is:
@
void setMyProperty(int value) {
if (_myProperty != value) {
_myProperty = value;
// start some really cool stuff
emit myPropertyChanged(_myProperty)
}
}
@But it's not the only one possible
