Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

[Tudor Girba]

Hi,

For your tabulator example, you can do something like:

browser := GLMTabulator new.
browser title: 'Código'.
browser column: #code.
browser transmit 
to: #code;
  transformed: [ :text | GTPlayPage new content: text ];
andShow: [ :a :page | a custom: (GTPlayground new startOn: page) ].
^ browser openOn: 'a := 42’.

Does this help?

Cheers,
Doru

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

[Offray Vladimir Luna Cárdenas]

Hi,

I'm still kind of lost here. If I try with these approaches I get a 
*new* GTPlayground window populated with content, instead of an embedded 
one. How can I made this GTPlayPage one that is embedded in a spec 
glamour interface, like the one in the minimalist example: a dictionary 
with two keys/values: one which is shown as text and other that is shown 
as a playground, both populated with the content in the dict values and 
both, embedded in a widget instead of on separate windows. Is this 
possible with the current Spec-Glamour implementation?, if not how can 
be it extended to make this happen?


Thanks,

Offray

I would expect (content is the GlamourPresentationModel)

content glmPres codePresentation text: 'new text'.

but it does not work.

Well that’s actually much easier. :-) What you need to do is to use the 
presentationClass:startOn: API method.

| ui |
ui := GlamourPresentationModel new.
ui presentationClass: GTPlayground startOn: (GTPlayPage new saveContent: '42').
ui openWithSpec

I just realized that this was not clear from the examples in the class comment.

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

[Offray Vladimir Luna Cárdenas]

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

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:

ifTrue: [ self rebuildWithCodeLayout ].

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;

yourself.
self needRebuild: false.

content needRebuild: true.
Transcript show: 'texto + ', self content asString, String cr..
self buildWithSpecLayout: newLayout.

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

I would expect (content is the GlamourPresentationModel)

content glmPres codePresentation text: 'new text'.

but it does not work.

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.

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).

Hi Johan,

I have not found more errors on the booklet, but I think that I'm not 
getting the explanation of dynamic spec. Consider this code:



==
GrafoscopioGUI Class>>exampleBootstrapDynamicUI
"Starting from an example UI from the Spec-Glamour, to customize 
towards the grafoscopio

UI and get some ideas"

|notebook leftUpperPanel leftPanel treeBrowser |

notebook := GrafoscopioNode new becomeDefaultTestTree.

"Defining the tree roots part"
leftUpperPanel := DynamicComposableModel new.
leftUpperPanel instantiateModels: #(tree TreeModel).
leftUpperPanel tree
roots: notebook children;
childrenBlock: [:node | node children ];
displayBlock: [:node | node title ].
leftUpperPanel layout: (SpecLayout composed
add: #tree;
yourself).
"to debug upto here uncomment the next line, and comment all other 
'openWithSpec' ones"

"leftUpperPanel openWithSpec."

"Integrating the previous tree with the node header and creating 
the body according to

the tags on the node"
leftPanel := DynamicComposableModel new.
leftPanel assign: leftUpperPanel to: #roots.
leftPanel instantiateModels: #(header TextInputFieldModel).
treeBrowser := DynamicComposableModel new.
leftUpperPanel tree

]
]
].
leftPanel layout:
(SpecLayout composed

yourself).

treeBrowser assign: leftPanel to: #leftTree.
treeBrowser layout:
(SpecLayout composed
newRow: [:r | r add: #leftTree; add: #body ];
yourself
).
treeBrowser openWithSpec.
==

I can get the interface shown here:



and when I move between nodes in the upper left tree the correspondent 
name in the lower left input box changes accordingly, but nothing else 
happens on the right side panel. I have put the definition of the type 
and contents of such panel inside a whenSelectionChanged block, as you 
can see in the previous code, because I think that right panel should 
change according to the type of node that is selected, but this doesn't 
work. The debug info that I send to a transcript show that #body becomes 
a GlamourPresentationModel or a TextModel depending on which node I'm 
selecting. I don't know what I'm doing wrong or how this dynamic spec is 
supposed to behave... well, dynamically, and accordingly making layout 
components to change on the fly.


How can I make the right panel change to become a 
GlamourPresentationModel or a TextModel in Spec-Glamour?


Thanks,

Offray

[Offray Vladimir Luna Cárdenas]

Hi,

Lets try something simpler. Consider this code:

=
| data m1 m2 |

data := { 'first' -> 'I\"m just text' . 'second' -> 'ProfStef 
openPharoZenWorkspace'} asOrderedDictionary.


m1 := DynamicComposableModel new.
m1 instantiateModels: #(list ListModel).
m1 list items: (data keys).
m1 layout:
(SpecLayout composed
add: #list;
yourself).

m2 := DynamicComposableModel new.
m2 instantiateModels: #(right TextModel).
m2 assign: m1 to: #left.
m1 list
whenSelectedItemChanged: [:item |
item
ifNil: [
m2 instantiateModels: #(right TextModel).
m2 right text: ''
]
ifNotNil: [
item = 'first'
ifTrue: [
m2 instantiateModels: #(right TextModel).
Transcript show: m2 right asString, String cr
].
item = 'second'
ifTrue: [
m2 instantiateModels: #(right 
GlamourPresentationModel).

Transcript show: m2 right asString, String cr].
]
].

m2 layout:
(SpecLayout composed
newRow: [:r | r add: #left; add: #right];
yourself).
m2 openWithSpec

=

Shouldn't be #right dynamically defined according to the values of 
'item' and be replaced on the m2 layout? The transcript show that 
anytime I change the selection in this small spec interface, m2 right is 
changed. Is it not what I'm putting in the right side of the interface 
with the line which says:  "newRow: [:r | r add: #left; add: #right];"


How can I made spec in this small example show the respective value in 
the dictionary when the key value is "first" inside a TextModel and the 
respective value in the dictionary when the key value is "second" inside 
a GlamourPresentationModel?


Cheers,

Offray

[Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

[Offray Vladimir Luna Cárdenas]

Hi,

Thanks to NIcolai's help with his minimalist example I'm on track now 
and finally I have started to understand better the events in Spec. My 
problem was in the incorrect use of whenHighlightedItemChanged. Now the 
code its working fine and I can browse the tree and see the related 
contents on the respective UI panels (see attached screenshot and code 
at [*] at the end to see how was solved).


Now I'm facing another issue: As you can see in the attached screenshot 
the UI has four parts: A tool bar above all, a tree with the node title 
(called node header) at left and a bigger panel at right with node 
contents (called node body). I would like to make the node body behave 
in a similar way as in my previous non-Spec interface, so it can react 
differently according to the node tags. If the node is tagged as code, 
it will become a playground with node contents inside such playground. 
If node is not tagged it will be a text like now (this is already 
working). So my questions are:


1) How can I populate a Spec-Glamour playground with a particular text code?
2) How can I initializeWidgets with some kind of conditions depending on 
the kind of selection I have done on the tree? At this moment my 
initializeWidgets look like this:


==[2a]===
GrafoscopioGUI>>initializeWidgets
"Buils graphical interface elements"

windowMainMenu := self windowMainMenu.
tree := self tree.
nodeHeader := self newTextInput.
nodeBody :=
tree selectedItem notNil
ifTrue: [ self updateBody ]
ifFalse: [nodeBody := self newText].
windowMainMenu applyTo: self.
self focusOrder
add: windowMainMenu;
add: tree;
add: nodeHeader;
add: nodeBody.


and my updataBody (where I think that this conditional behavior could be 
looks like this:


==[2b]===
GrafoscopioGUI>>updateBody
"update the displayed content associated to the body of a node"

(tree selectedItem content tags = 'código')
ifTrue: [
^ nodeBody text: 'I should be playground because I am 
tagged as ', tree selectedItem content tags

]
ifFalse: [
^ nodeBody text: tree selectedItem content body
]


So, more precisely, what I need to put in the ifTrue part of [2b] to 
make the interface to return a playground with pre-populated code? (is 
it the proper place?)


Finally, here is the code that made the tree update properly, just for 
the curious ones.


==[*]
GrafoscopioGUI>>tree
| notebook |
notebook := GrafoscopioNode new becomeDefaultTestTree.
tree := TreeModel new.
tree
roots: notebook children;
childrenBlock: [:node | node children];
displayBlock: [:node | node title ].
tree whenHighlightedItemChanged:
 [tree selectedItem notNil
ifTrue: [
self updateHeader.
self updateBody.
]
 ].
^ tree


Cheers,

Offray

Ohh, what is missing is not in the example, but in my

something like "example openWithSpec" to start deconstructing it,
but I'm still lost about it. I will be working on it today and
tomorrow to see if I can come with better questions.


Ok, for this example you can just start it with:

TreeDemo new openWithSpec

It opens a window with two panes, the upper pane shows a tree with 
some nodes (subclasses of class Morph)
The lower pane shows the text(name) of the selected node. You can 
change and accept (cmd+s) the text in the

lower pane, which will update the name of the tree node.
