Apache PivotでGroovyを使うサンプル

CreateLabel.groovy

@Grapes([
  @Grab("org.apache.pivot:pivot-core:2.0"),
  @Grab("org.apache.pivot:pivot-wtk:2.0"),
  @Grab("org.apache.pivot:pivot-wtk-terra:2.0")
  ])
import org.apache.pivot.wtk.*

//メソッドはバインディング変数(クロージャ)で作成しないといけない
createLabel = { window ->
  def label = new Label()
  label.text = "Hello Groovy! 2"
  label.styles << [font:"Arial BOLD 24", color:"#ff0000",
    horizontalAlignment:HorizontalAlignment.CENTER,
    verticalAlignment:VerticalAlignment.CENTER]
  
  window.content = label
}

GroovyPivotInit.groovy

@Grapes([
  @Grab("org.apache.pivot:pivot-core:2.0"),
  @Grab("org.apache.pivot:pivot-wtk:2.0"),
  @Grab("org.apache.pivot:pivot-wtk-terra:2.0")
  ])
import org.apache.pivot.wtk.*

//stylesに一括で設定できる様に細工
Component.StyleDictionary.class.metaClass {
  leftShift << { Map map ->
    map.each {
      put(it.key, it.value)
    }
  }
}

GroovyScriptApplication.groovy

@Grapes([
  @Grab("org.apache.pivot:pivot-core:2.0"),
  @Grab("org.apache.pivot:pivot-wtk:2.0"),
  @Grab("org.apache.pivot:pivot-wtk-terra:2.0")
  ])
import org.apache.pivot.wtk.ScriptApplication

 * GroovyからApache PivotのBXMLを実行
 */

   * BXMLファイルを実行
   * @param args --src=/BXMLファイル名
   */
  public static void main(String[] args) {
    ScriptApplication.main(args)
  }
  
}
