[Solved]Specific signals/slots problem.

[jalue]

Hey all,

New to the forums here at Qt Project. Been on the BlackBerry Developer forums for a short time and trying to learn Qt among other things to develop apps on BlackBerry (and perhaps other mobiles later when I get the hang of things). Anyways, I wrote a simple app to test out Signals and Slots with C++ and QML.

I have no idea what is wrong with my QObject::connect function. It doesn't seem to be sending or triggering anything. I think I have all the necessary code tweaks to get the connect to work, but.... I'm missing something...

Any help would be greatly appreciated and thanks in advance.

--Edit--
Didn't include the main.cpp file because it just creates a new class object.

.hpp file:

@// Default empty project template
#ifndef Testme_HPP_
#define Testme_HPP_

#include <QObject>

namespace bb { namespace cascades { class Application; }}
namespace bb { namespace cascades { class TouchEvent; }}

namespace bb { namespace cascades { class ImageView; }}
namespace bb { namespace cascades { class Label; }}

/*!

• @brief Application pane object

Use this object to create and init app UI, to create context objects, to register the new meta types etc.

Figured it out.

It would be nice if you'd post the solution as well as the problem...
And please mark the topic with [solved] (by editing your first post) when you're done.

I guess Bold tags don't work in quotes.

Solution:
Should've used the qml object for making changes and setting the QObject::connect, even though the ImageView is in qml2.
