SceneManager

Hi,
I'm create form for showing documents in my application. In documents I have links for navigation between different documents.

And when i try go to this link(I need go from first document to next)


SceneManager* pSceneManager = SceneManager::GetInstance();

ForwardSceneTransition  transction( IDSCN_DOCUMENT_VIEW_FORM,
                                        SCENE_TRANSITION_ANIMATION_TYPE_LEFT,
                                        SCENE_HISTORY_OPTION_ADD_HISTORY,
                                        SCENE_DESTROY_OPTION_KEEP);

pSceneManager->GoForward(transction, list);

I get next exeption.

 [E_INVALID_ARG] Invalid argument is used. Can't forward to current Scene.

Why?

Probably the problem is your sceneID. Make sure it is used in your Form and you put correct name.

You can use just:

ForwardSceneTransition  transction( IDSCN_DOCUMENT_VIEW_FORM,
                                        SCENE_TRANSITION_ANIMATION_TYPE_LEFT);

Hi,
I have checked. This approach should works.
Possibly you use wrong SceneId (like supposed above) or unclear what incoming param 'list' contains. Also E_INVALID_ARG comes if you try to perfrom transition to the same scene where you are.

Yes, i try to perform  transition to the same scene. I have scene for showing documents. Then i go by link  from 1 document to other but scene is one.

I suppose you can't navigate between same scene. I doesn't work like web browser.

Use two scenes instead and change Form content after getting scene callback.

Do you think this is a best way to show for example nested list i need have 2 forms?

Serikov

If I will be used 2 form. How can i restore previous form state after back action? (If in the formstack > 4 forms)

Hi,
param SCENE_DESTROY_OPTION_KEEP param should save state(for example) :
1)For transition Form1->Form2
        ForwardSceneTransition  transition( Scene2,
                                                SCENE_TRANSITION_ANIMATION_TYPE_LEFT,
                                                SCENE_HISTORY_OPTION_ADD_HISTORY,
                                                SCENE_DESTROY_OPTION_KEEP);//the scene will not be destroyed and will be added to the history
 r=pSceneManager->GoForward(transition);
2)For transition Form2->Form1 (back key)

    BackwardSceneTransition  transition(Scene1,
        SCENE_TRANSITION_ANIMATION_TYPE_RIGHT,
        SCENE_DESTROY_OPTION_KEEP);
       pSceneManager->GoBackward(transition);

Just look at this also:

So far I didn't use nested list for Tizen.  You can check here:

https://developer.tizen.org/dev-guide/2.2.1/org.tizen.native.apireference/classTizen_1_1Ui_1_1Controls_1_1ListView.html

 

With scene activation you get callback: OnSceneActivatedN(). Here you can change Form content - use parameters from IList

passed by that callback. This approach works fine and is strongly recommended.

 

Instead use 2 Forms to swap them from time to time you can add a few Panels and fill them in with content you want to show.

This make sense only if you got a few documents to show.
