Class protocol:

 addBindingsTo: env for: anInstance channel: aChannel

(comment from inherited method)
add bindings as required to allow the GUI Painter to operate on an instance of me

 basicsEditSpec

This resource specification was automatically generated
by the UIPainter of ST/X.

Usage example(s):

UIPainter new openOnClass:ScrollableViewSpec andSelector:#basicsEditSpec

 fromView: aView callBack: aTwoArgCallBackBlock

(comment from inherited method)
create and return a new instance, by walking over a view's hierarchy.
(used by the UIPainters pick-a-view function).
For every created subSpec-element, the callBackBlock is evaluated,
passing the specElement and the view as arguments.
This can be used to fill in additional information, which cannot be
extracted from the view (for example: names, aspects etc.).
The callBack argument may be nil.

 canResizeSubComponents

(comment from inherited method)
answer whether included sub components can be resized or are handled by the view itself

 isLayoutContainer

 hasHorizontalScrollBar

return the value of the instance variable 'hasHorizontalScrollBar' (automatically generated)

 hasHorizontalScrollBar: something

 hasVerticalScrollBar

return the value of the instance variable 'hasVerticalScrollBar' (automatically generated)

 hasVerticalScrollBar: something

 miniScrollerVertical

return the value of the instance variable 'miniScrollerVertical' (automatically generated)

 miniScrollerVertical: something

 buildComponentFor: aBuilder in: v

low level create - no attributes are set.
Can be redefined for special creation (see arbitraryComponentSpec)

 setupInitialLayoutFor: aSubView

 skippedInLiteralEncoding

define the inst-slots which are skipped when generating a literalArrayEncoding;
(to skip the ones with default values.)

 componentFromView: aView callBack: aBlock

 fromView: aView callBack: aBlock

(comment from inherited method)
extract attributes from aView

 defaultModelClassFor: something

used by the UIPainters aspectGenerator

 needsRebuildForAttributes

(comment from inherited method)
return true, if my view must be rebuild
when an attribute changes.
True may be returned by a concrete subclass,
if attribute changes imply a view-class change
(such as horizontal/vertical)

 viewClass

(comment from inherited method)
returns the view class to be created for that spec
This is an instance method, since it may depend on some attribute.
However, here we ask the class, to allow for class-specific defaults.
