Hi,

i have some trouble when want to passing object from 1 qml to other qml.

sample code :

//do some import

public A : public QObject {

Q_OBJECT

Q_PROPERTY(int value READ value);

    public :

          A();

          ~A();

          int value()

          void setValue(int value);

    private :

        int value;

}

// then i register this object to main.cpp

qmlRegisterType<A>("model", 1, 0, "A");

then X.qml

import model 1.0

import api 1.0

NavigationPane{
             id: nav
             Page{
                          Button:{
                                       onclick:{
                                                    nav.push(page2);
                                       }
                          }
                          onCreationComplete : {
                                       myApi.call();
                          }
                          attachedObject: [
                                       Api{
                                                    id : myApi
                                                    onComplete{
                                                                 z.a = a
                                                    }
                                       },
                                       Test{
                                                    id = page2;
                                       }
                          ]
             }
}

//Test.qml

import model 1.0

Page{
             property A a
             Label{
                          text : a.getValue();
             }
}

i already tried like this, but it didnt work, and tried using Q_PROPERTY at object A still not work. Could you help me please ?

Use:

Label {
text: a.value
}

Because its a Q_PROPERTY and not a Q_INVOKABLE you don't need write it as a function call

You also haven't defined the property 'z' anywhere so I'm not sure where that reference is coming from

[chanzdevilz]

i tried it already, but it still not work. 

[dridk]

Page{
             Label{
                          text : a.value
             }

attachedObject : [

A {

id:a

}

]

}

About property, I m not sure property CustomType works. You should set : property QObject instead

[chanzdevilz]

i have tried it too. instead using QObject, i using property variant a. still not work.

when look on slog2info, i got "TypeError: Result of expression 'A' [undefined] is not an object." that happen when 

Api{

       id : myApi
       onComplete{

              console.log(a.getValue()); << happen at here
              z.a = a 
       }
},

[dridk]

GetValue should be Q_INVOKABLE 

[chanzdevilz]

already implement it, still not work. could you give me some example or reference for me so i could check my code from it ?

try attaching an object in the Page object like

1st QML:

page.object = passedObject

2nd QML:

property variant object
