I'm using Invocation Framework as client and as target.

client works well.

now added support to be invoked as a target.

added in bar descriptor:

<invoke-target id="my-id">
    	<invoke-target-name>my-name</invoke-target-name>  		
  		<icon>assets/images/my-icon.png</icon>    	
    	<type>APPLICATION</type>
    	<filter> 
    		<action>bb.action.OPEN</action>
      		<mime-type>image/png</mime-type>
      		.... some more		
    	</filter>
    </invoke-target>

Using the InvocationClient APP from Cascades-Community-Samples at Github I can query my app, app will be found and also launched or opened.

so the app is known as a target and filtering works as expected.

But I don't get the InvokationRequest in my SLOT:

hpp:

private Q_SLOTS:
  void handleInvoke(const InvokeRequest& request);

cpp:

void MyApp::handleInvoke(const InvokeRequest& request) {
  qDebug() << "Invoke Request to handle";
}

debugged and found that the connect wasn't done.

this is my connect code:

m_invokeManager = new InvokeManager(this);
	ok = connect(m_invokeManager, SIGNAL(invoked(const InvokeRequest&)), this, SLOT(handleInvoke(const InvokeRequest&)));
	if (!ok) {
		qDebug() << "connect handleInvoke failed";
	}

 Connection failed with:

Object::connect: No such signal bb::system::InvokeManager::invoked(const InvokeRequest&)

 any idea what could be wrong ?

Probably need the namespaces... try this

_invokeManager = new InvokeManager(this);
	connect(_invokeManager, SIGNAL(invoked(const bb::system::InvokeRequest&)),this, SLOT(onInvoked(const bb::system::InvokeRequest&)));

thx, Kyle

added the namespace bb::system for connecting slots and signals

and got compile errors

removed use namespace bb::system from headerfile

cleaned project

and suddenly the errors gone and the slot was used

all works now as expected

BTW: had the same problem with another project.

changed to full bb::system:: namespace for the connect,

also got immediately error that invoked... etc is unknown

clear project and new build didn't help, but closing and re-opening the workspace did it.

so next time with unexpected errors I'll close/reopen workspace first ;-)
