swing - scala中的摇摆问题

Question

我正在查看一些在 scala 2.9.1 中出错的示例代码：

import javax.swing.JFrame
import javax.swing.JMenuBar
import javax.swing.JButton
import javax.swing._

import com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel
import javax.swing.{UIManager}
object UI extends SimpleSwingApplication {   
    UIManager.setLookAndFeel(new NimbusLookAndFeel)  
}

错误：/some/path/Cls.scala:25：错误：未找到：类型 SimpleSwingApplication

Answer 1

原来我必须像这样运行我的代码：

scala -classpath /usr/share/java/scala-swing.jar Cls.scala

成功的代码库是：

import javax.swing.JFrame
import javax.swing.JMenuBar
import javax.swing.JButton
import javax.swing._
import scala.swing.SimpleSwingApplication
import scala.swing._


object UI extends SimpleSwingApplication {   
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName())  
    def top = new MainFrame {
      title = "First Swing App"
      contents = new Button {
        text = "Click me"
      }
    }

    def main() {
        println("hi")
    }
}
