Hi,

I've reading the code at [1] but I'm still having problems understanding the dynamic spec. I have created a small dictionary and populated with data, then created the accessors and initializePresenter, initializeWidgets and rebuildWithdCodeLayout and rebuildWithTextLayout, as you can see on the following snippets, but nothing happens despite the debugging Transcript is showing me that the content subwidget has the proper model, but is not rebuild in the GUI.

Any help is, as always, very much appreciated.

Hi Offray,

I think you have to call
    self needRebuild: false.

in both rebuild... methods.

Otherwise the all "inner"-widgets are rebuild:

 

[1] https://github.com/spec-framework/documentation/blob/master/output/book.md#rebuildDynamically

----------------------
DynamicDict>>initializeWidgets

    | data |
    data := { 'first' -> 'I\"m just text' . 'second' -> 'ProfStef openPharoZenWorkspace'} asOrderedDictionary.
    list := self newList.
    list items: data keys.
    content := self newText.
    self focusOrder
        add: list;
        add: content.
----------------------
DynamicDict>>initializePresenter
    list whenSelectedItemChanged: [:item |
        item = 'first'
            ifTrue: [ self rebuildWithTextLayout ].
        item = 'second'
            ifTrue: [ self rebuildWithCodeLayout ].       
    ]
----------------------
DynamicDict>>rebuildWithCodeLayout
    | newLayout |
   
    content := self instantiate: GlamourPresentationModel.
    newLayout := SpecLayout composed
        newRow: [:row |
            row
                add: #list right: 0.7;
                add: #content left: 0.3];
        yourself.
    self needRebuild: true.
    content needRebuild: true.
    Transcript show: 'código + ', self content asString, String cr.
    self buildWithSpecLayout: newLayout.
----------------------
DynamicDict>>rebuildWithTextLayout
    | newLayout |
   
    content := self newText.
    newLayout := SpecLayout composed
        newRow: [:row |
            row
                add: #list right: 0.7;
                add: #content left: 0.3];
        yourself.
    self needRebuild: false.
    list needRebuild: false.
    content needRebuild: true.
    Transcript show: 'texto + ', self content asString, String cr..
    self buildWithSpecLayout: newLayout.
----------------------

Cheers,

Offray

From what I understand and what I can see in your code, you want to modify a widget when the UI is open. However you never trigger the rebuilding of the window. For example, see the Spec docs that I sent, where in 9.1 there is code that calls buildWithSpecLayout: . 

Actually, I am not sure you need to subclass DynamicComposableModel since the number of widgets never changes. You can use a normal ComposableModel subclass and use what is detailed in 9.1 to change the layout between the two options you want to have (a TextModel or a GlamourPresentationModel).

Shouldn't be #right dynamically defined according to the values of 'item' and be replaced on the m2 layout?
