Spec - Grid/Table Layout

I'm doing a TreeModel. As you know, widgetDo is not a message of TreeModel, that's why i was asking you if there something wrong. As i asked you in a old post, column: is not a message of TreeModel, so, where do i have to create that message? The following code means to me that i have to create column: into MorphTreeAdapter, a class that i haven't got into my Pharo 2.0.

MorphTreeAdapter>>#columns:

columns: columns 

 self widgetDo: [ :w | 

w columns: columns. 

  w resizerChanged. 

w updateList ]

I am sure that Adapters understands widgetDo:

To which objects do you send this message ?

Hi Ben, 

are you sure that the message "widgetDo:" is  the right one? It's not a message that my object looks to understand. 

Thanks in advance.

It is definitely defined in TreeModel :)

Very very very good Ben, thanks a lot. Last question: you use the "columns:" message, but it's not defined in TreeModel. You defined it here

MorphTreeAdapter>>#columns:

columns: columns 

 self widgetDo: [ :w | 

w columns: columns. 

  w resizerChanged. 

w updateList ]

in the brand new Class MorphTreeAdapter. What's the difference between define columns: here instead of in the TreeModel class?

Great job and thank you!

tree := TreeModel new.

tree openWithSpec.

tree columns: (Array 

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item first asString asMorph ]; headerButtonLabel: 'Name' font: nil; yourself)

Yes Ben, too much threads! That's why i'm a little bit confused! That's what i understood: i've got two roads-> use TreeModel as you did with Pamela Anderson or use the simple and nested SpecLayout (SpecLayout composed) as Clement did.

If in your TreeModel i can put a RadioButtonModel or a ButtonModel or so on... we got the deal!

I guess too much threads :)

I answer this in another thread I think :P

the block provided to displayBlock:/rowMorphGetSelector: can return anything understanding asMorph.

So you can return any custom morph there :)

I think the following work

tree columns: (Array 
with: (TreeColumnModel new displayBlock: [:node | node content first asString ]; headerLabel: 'Name'; yourself)
with: (TreeColumnModel new displayBlock: [:node | node content second asString ]; headerLabel: 'Last Name'; yourself)
with: (TreeColumnModel new displayBlock: [:node | node content third asString ]; headerLabel: 'Age'; yourself)

with: (TreeColumnModel new displayBlock: [:node | node content fourth asString ]; headerLabel: 'Gender'; yourself)

with: (TreeColumnModel new displayBlock: [:node | Morph new ]; headerLabel: ‘Morph'; yourself))

or

tree columns: (Array 

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item first asString asMorph ]; headerButtonLabel: 'Name' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item second asString asMorph ]; headerButtonLabel: 'Last Name' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item third asString asMorph ]; headerButtonLabel: 'Age' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item fourth asString asMorph ]; headerButtonLabel:  'Gender' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | Morph new ]; headerButtonLabel:  'Morph' font: nil; yourself)).

And you get something like

Yes Clement, i've got your .st file. I saw it in Nested Layout thread. I file in it in Pharo and i see that is not as good as a fashion window is. Maybe Morphic is the right solution but, in that way, we are leaving the idea of Bahman, and the 2nd Spec Tuto is in danger!

However, you asked to Ben the same question that i did: can i put some widgets in these cells or only String? 

Thanks again!

Ben answered in another thread:

About table, I have an example which will be running soon in Pharo (the changes are waiting to be integrated)

tree := TreeModel new.

tree openWithSpec.

tree columns: (Array 

with: (TreeColumnModel new displayBlock: [:node | node content first asString ]; headerLabel: 'Name'; yourself)

with: (TreeColumnModel new displayBlock: [:node | node content second asString ]; headerLabel: 'Last Name'; yourself)

with: (TreeColumnModel new displayBlock: [:node | node content third asString ]; headerLabel: 'Age'; yourself)

with: (TreeColumnModel new displayBlock: [:node | node content fourth asString ]; headerLabel: 'Gender'; yourself)).

tree roots: {

{'Benjamin'.'Van Ryseghem'.'26'.'M'}.

{'Pamela'.'Anderson'.'Far too much'.'F'}

}

Right now, you can get the same by

- adding MorphTreeAdapter>>#columns:

columns: columns 

 self widgetDo: [ :w | 

w columns: columns. 

  w resizerChanged. 

w updateList ]

And then evaluating:

tree := TreeModel new.

tree openWithSpec.

tree columns: (Array 

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item first asString asMorph ]; headerButtonLabel: 'Name' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item second asString asMorph ]; headerButtonLabel: 'Last Name' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item third asString asMorph ]; headerButtonLabel: 'Age' font: nil; yourself)

with: (MorphTreeColumn new rowMorphGetSelector: [:node | node item fourth asString asMorph ]; headerButtonLabel:  'Gender' font: nil; yourself)).

tree roots: {

{'Benjamin'.'Van Ryseghem'.'26'.'M'}.

{'Pamela'.'Anderson'.'Far too much'.'F'}

}

Ben, in each cell, can we put something else than a String ? If so, can you add an example in the code above ? Thanks.

I guess doing Ben's solution is the best. I did it with nested layout but it is definitely not as good (see file in attachment, add it in your image then evaluate SpecTable new).

Hi Clement;

I did the Spec tuto made by Bahman (great tuto). As him, i'd like to put some widgets into it. Is it possible? Maybe with the method "items:"? I don't know if the solution that Ben give to us (use Morphic instead of Spec) is suitable, that's because his UI looks like a list that accept only string. Maybe i'm wrong, can you give us more explanations? Or is it something new for you too?

Thanks for your help!

Hello,

Actually I had the same problem, I think the best widget that exists for that right now is MultiColumnListModel.

For example, in the senders window (in attachment), the top panel is a MultiColumnListModel. You can have as many lines and as many columns as you want. 

We do not have yet a tableLayout, but we miss it. If you plan to implement it, we will be interested in integrating it into Pharo.

Ben can advise you on how to implement that.

Hi all,

Is there a grid/table layout available in Spec?  Something like an HTML
table or Swing's GridLayout?  If not, how may I achieve such a
functionality?

I'd appreciate any hints/pointers.
