Description:

The GridBagConstraints class holds the constraints for each child under control of the layouter
GridBagLayoutView. In addition to just be a placeholder for the constraints and some
temporary information during the layout process, the GridBagConstraints class also supports
the decoding and encoding its instance information from and into a literal array. This is
necessary in order to be used as a winSpec element.

For the valid values of each public instance variable see the documentation of the GridBagLayoutView.

Class protocol:

 new

Create an initialized instance of myself.

Instance protocol:

 anchor

 anchor: something

 fill

 fill: something

 gridHeight

 gridHeight: something

set the value of the instance variable 'gridHeight'

 gridWidth

 gridWidth: something

set the value of the instance variable 'gridWidth'

 gridX

 gridX: something

set the value of the instance variable 'gridX'

 gridY

 gridY: something

set the value of the instance variable 'gridY'

 insets

 insets: something

 ipadX

 ipadX: something

 ipadY

 ipadY: something

 minHeight

 minHeight: something

 minWidth

 minWidth: something

 tempHeight

 tempHeight: something

 tempWidth

 tempWidth: something

 tempX

 tempX: something

 tempY

 weightY

 weightY: something

 fromLiteralArrayEncoding: encoding

Read my values from an encoding. The encoding is supposed to be of the form:
(GridBagConstraints
insets: (Insets left: 1 right: 1 top: 1 bottom: 1)
gridX: 1 gridY: 1 gridWidth: 1 gridHeight: 1
weightX: 1.0 weightY: 1.0 ipadX: 1 ipadY: 1 anchor: #CENTER fill: #BOTH
)
This is the reverse to literalArrayEncoding.

usage example(s):

GridBagConstraints new fromLiteralArrayEncoding:#(GridBagConstraints insets: #(Insets 96 97 98 99) gridX: 101 ) #(#GridBagConstraints anchor: #CENTER fill: #BOTH) decodeAsLiteralArray

 fromLiteralArrayEncodingOld: encoding

Read my values from an encoding. This is the reverse to literalArrayEncoding.

 literalArrayEncoding

Encode myself as an array, from which a copy of the receiver can be
reconstructed with #decodeAsLiteralArray.

usage example(s):

GridBagConstraints new literalArrayEncoding

 literalArrayEncodingOld

Encode myself as an array, from which a copy of the receiver can be
reconstructed with #decodeAsLiteralArray.
The encoding is:
(GridBagConstraints
#( Insets left right top bottom )
gridX gridY gridWidth gridHeight weightX weightY ipadX ipadY anchor fill
)

 initialize

Set all non-temporary instance variables to default values.
Warning: no application should depend on this default settings and should always initilize
the constraints themselves.
