Hey.

I am new to QML.  I have some Tab's that I want to share action arrays to.  This is to decrease duplication. 

TabbedPane {
    id: myPane
    property list<ActionItem> actionListProperty: [
        ActionItem {
            title: "123"
        }
]
  
    Tab {
        Page {
                Container
                {
		        actions : actionListProperty
	        }
        }
    }
}

 Is something like this possible?  I get an error in Momentics complaining about the < character in my list property, but I am following the directions given here : http://qt-project.org/doc/qt-4.7/qml-list.html

Another failed attempt

Page {
    id: myPage
    property AbstractActionItem myList: [
        ActionItem {
            title: "123"
        }
        ]
    
    
    Tab {
        
            Page {
                    actions : myPage.myList
	                 
	             }
        }
}

Would it work as attachedObjects?

I am sure it can be done in C++
You would just need to define the object name for TabbedPane

I would also like to know the answer to this question. I am trying to maintain a basic list/array in QML that I can add items to depending on user interactions but everything I try, e.g. Javascript array does to work for me.

With Javascript it can be done, but in qml it won't work. There is a bug in latest qt - you can create lists but you cannot change them. It is described somewhere in QT docs. That is probably why qml lists are not mentioned in cascades docs

And how can a list/array be done using javascript alone without QML? I would like to have the equivalent of an array property that can be modified, with things added via push() etc. Sorry if this is an obvious question but I am relatively new to QML and Javascript.

[rcebryk]

You must google, how to create lists and modify them in Javascriptem. I am afraid that you will be able to create lists of simple types likes int, float etc. In qml you can easily create a static list with any objects but you can not add/delete items.

I ended up giving up trying to figure it out and dropped the feature I wanted to add using lists (out of frustration).  I came to the (perhaps incorrect) conclusion that QML is only powerful enough for screen layouts.  Seems like a wasted oportunity and using QML actually took longer than C++ because all the time I saved on typing was spent trying to find work arounds for missing features.  I also found the inability to debug a problem for complex application development.
