Spec: Binding widgets how to

Hi Nicolai,

That was the issue. Now it's working! I was trying to test different combinations to see why UI updating was not happening but I got the variations wrong (one true, another false, instead of both false :-) ).

The next step I'm working on in populating the GTPlayPage with some particular content. In my previous interface I made something like this:

-[1]---------------------
GrafoscopioBrowser>>panelAsCodeFor: aNode
    "Shows an interactive playground for Smalltalk code in a node body"

    browser := GLMTabulator new.
    browser title: 'Código'.
    browser column: #code.
    browser transmit
        to: #code;
        transformed: [ GTPlayPage new content: aNode body ];
        andShow: [ :a | a custom: GTPlayground new ].
    browser sendToOutside: #nodeBody from: #code -> #text.
    ^ browser.
------------------------

In this one I tried some variation of GlamourPresentationModel>>glmPres that let the user predefine a content for the GTPlayPage like this:

-[2]----------------------
glmPresWithContent: aString
    glmPres isNil ifTrue:[
        glmPres := GTPlayground new startOn:  (GTPlayPage new content: aString)].
    ^glmPres
---------------------------

but if I try running the interface with this I get: "MessageNotUnderstood: GlamourPresentationModel>>content:", so I think that something more is needed to create Playgrounds in the Spec-Glamour that are pre-populated with content.

How can I create a playground inside a Spec-Glamour interface that is already populated with a given content?

Thanks,

Offray

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

Sorry for the lateness and short reply but I’m involved in a bunch of other things that are taking almost all of my time ...

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?
