Re: [Pharo-users] Spec problem creating dynamci UIs

      There is no way to tell to spec that this layout should automatically 
expand the window.
And I think this is not the default behaviour.

If you want to change the size you can still do manually

	myModel extent: newWidth@newHeight

And this should work

I'm probably doing this all wrong, but I have a problem creating a dynamic UI
with Spec.
I want a small window which shows more information when a /Show more
details/ button is clicked.
Here's an example.

when I click /Show More/ I want something like this (a bigger window with
more fields):
<http://forum.world.st/file/n4747139/PharoScreenshot.8.png>
But when I change the Spec layout the window size remains the same as it was
set in /initialExtent/ - so it does not display properly with the extra
fields.

I can't find any way of rebuilding the window so that it shows the bigger
layout properly.
Here's the spec for the basic window:
*basicSpec*
<spec: #default>
|row1|
row1 := SpecLayout composed
  newRow: [ :row |
      row
      	add: #label1;
      	add: #field1
  ] height: self inputTextHeight;
  yourself.
^SpecLayout composed 
  newColumn:[:column| 
      column add:row1; addSplitter; add:#btnMode height: self toolbarHeight ;
addSplitter].
Here's the spec for the detailed window:
*detailedSpec*
<spec>
|row2 row3|
row2 := SpecLayout composed
  newRow: [ :row |
      row
      	add: #label2;
      	add: #field2
  ] height: self inputTextHeight  ;
  yourself.
row3 := SpecLayout composed
  newRow: [ :row |
      row
      	add: #label3;
      	add: #field3
  ] height: self inputTextHeight  ;
  yourself.
^SpecLayout composed 
   newColumn: [ :column |
       column
      add: self basicSpec;
           add: row2;
  add:row3
   ];
   yourself.
Here's the code that switches Spec layouts:
*initializePresenter*
  super initializePresenter.
  btnMode action:  
      [ self needRebuild: false. 
       self label1 needRebuild: false.
      self field1 needRebuild: false.
      self btnMode needRebuild: false.
self buildWithSpecLayout: self class detailedSpec. ]
Is this a problem in Spec or just me being stupid?
