Documentation

CSSBuilder does not add new nodes as opposed to other popular builders, however it enhances every node with a new attribute: cssClass. Use this attribute to define (at least one) CSS class to be applied to that particular component. Additionally you can specify a name: property that will be used as a CSS id. This builder injects the following methods to the java.awt.Container class

Here is a sample demonstration of its usage, the following application relies solely on CSSBuilder to change its looks

stylesheet

* {
  background-color: red;
}

jbutton {
  background-color: blue;
  font-size: 120%;
}

#button1 {
  background-color: green;
  font-style: italic;
}

.active {
  background-color: yellow;
  font-weight: bold;
}

view script

application(title:'css', pack:true,
  locationByPlatform:true,
  iconImage: imageIcon('/griffon-icon-48x48.png').image,
  iconImages: [imageIcon('/griffon-icon-48x48.png').image,
               imageIcon('/griffon-icon-32x32.png').image,
               imageIcon('/griffon-icon-16x16.png').image]) {
   panel {
      gridLayout(cols: 1, rows: 3)
      button("One", name: "button1")
      button("Two", name: "button2")
      button("Three", name: "button3", cssClass: "active")
   }
}

This style sheet was applied using

import griffon.builder.css.CSSDecorator
CSSDecorator.decorate("style", mainFrame)

...

Starting with version 0.3 you'll be able to use Groovy expressions as values of CSS rules. You may add variables to a global CSSBindings object. CSSBindings's variables are observable. The following example demonstrates these new features

import groovy.swing.SwingBuilder
import griffon.builder.css.CSSDecorator
import griffon.builder.css.CSSBindings
import java.beans.PropertyChangeListener

// initialize default variables, currently
// screen: size of default screen device 
CSSBindings.instance.initDefaults()
def style = '''
jlabel {
  font-size: '${screen.width * 0.05}';
  color: '${active? "red": "blue"}';
}
'''
CSSBindings.instance.active = false
 
new SwingBuilder().edt {
  f = frame(size: [400, 200], show: true) {
    gridLayout(cols: 1, rows: 2)
    label("GROOVY")
    toggleButton("Click me!", id: "b")
    bean(CSSBindings.instance, active: bind{b.selected})
  }
  CSSDecorator.applyStyle(style, f)
}
 
CSSBindings.instance.addPropertyChangeListener({evt ->
   CSSDecorator.applyStyle(style, f)
} as PropertyChangeListener)
