Class Profligacy::Swing::LEL
In: lib/profligacy/lel.rb
Parent: Build

Layout Expression Language is a small regex like wiki language used to specify complex layouts in a tiny amount of space. The language is based on a Ragel based parser that configures a Swing GroupLayout with the right options to produce the desired effect. An example of LEL is:

 @layout = "
  [ label_1         | label3      ]
  [ (300,300)*text1 | (150)people ]
  [ <label2         | _           ]
  [ .message        | ^buttons    ]"

Which will produce a panel where you can place components. Otherwise it works exactly like Swing::Build except you pass the LEL expression in to the constructor instead of an array of symbols.
