MedNez any update on posting this example?

[MedNez]

I've signed the contribution agreement and the code is with BB to commit. If it's not up in the next day or two I'll upload it somewhere else temporarily!

Any news on getting this example posted? I don't see it on the samples page even now...

Long story short - I couldn't quite work out how to push my changes to Github.

Sorry about the delay, here is a link!

Hi men ,look this link

http://devblog.blackberry.com/2012/11/bbm-invocation-framework/

here is a active frames

[peter9477]

wilochoa14, what are you talking about? That link goes to a page on BBM and the invocation framework. It has nothing to do with active frames.

Hi,

the example in this thread did not work for me, i dont know why. But the following worked fine and its very easy to change the content of the SceneCover because "Application.cover" is a reference to this component.

AppCover.qml:

import bb.cascades 1.0

SceneCover {

    property alias extraText: testText.text
    
    content: Container {
        Container {
            layout: DockLayout {
            }
            background: Color.Black
             Label {
                  id: testText
                  horizontalAlignment: HorizontalAlignment.Center
                  verticalAlignment: VerticalAlignment.Center
                  text: "Intital Text"
                  textStyle.color: Color.create("#ebebeb")
            }
        }
    }
}

in main.qml

    onCreationCompleted: {
        Application.cover = appCover.createObject();
        Application.cover.extraText = "Changed Text"
    }
    //

    attachedObjects: [
        ComponentDefinition {
            id: appCover
            source: "AppCover.qml"
        }
    //

This might be an old thread, but I did figure it out.

In main.cpp, you can use 'app.setCover(new ActiveFrame());' or you can do it else. Do it here. Makes sense!

Second,

// ActiveFrame.cpp

#include "ActiveFrame.hpp"

ActiveFrame::ActiveFrame() :SceneCover(this) {

    // Load the QML for the cover and retrieve the root container
    qml = QmlDocument::create("asset:///screenCover.qml").parent(this);
    mMainContainer = qml->createRootObject<Container>();

    // Set the content of ActiveFrame
    setContent(mMainContainer);

    // Trigger an initial update of the content
    update();
}

ActiveFrame:: ~ ActiveFrame() {

}

void ActiveFrame::update() {

    // ...Here's where you update the cover...

    // You can trigger updates here as often as necessary
}

// ActiveFrame.hpp

#ifndef ACTIVEFRAME_HPP_
#define ACTIVEFRAME_HPP_

#include <bb/cascades/SceneCover>
#include <bb/cascades/Container>
#include <bb/cascades/QmlDocument>

using namespace bb::cascades;

namespace bb {
	namespace cascades {

		class Container;
		class QmlDocument;
		class QObject;

	}
}

class ActiveFrame : public SceneCover {
	Q_OBJECT

public:
    ActiveFrame();
    virtual ~ActiveFrame();

private:
    Container *mMainContainer;
    QmlDocument *qml;


};



#endif /* ACTIVEFRAME_HPP_ */

 Now, the QML is important. If you're coming from the QML example, you probably used "SceneCover {}". That was my problem!

Essentially, you're creating the SceneCover by new ActiveFrame() then calling the QML to load the Container{}. *NOTE* - You can't wrap this in a Page{}. Just tried it.

So pop in the import tag then Container{} into your screenCover.qml and you're done.

Mess around with this some more and you can get the signals to work .
