Scala Swing中的微調框

Question

如何操作： http://download.oracle.com/javase/tutorial/uiswing/components/spinner.html 使用說明：http://www.scala-lang.org/api/current/index.html#package？

Answer 1

如果您想知道如何將一個JSpinner添加到Scala swing應用程序中，您需要使用Component.wrap（JComponent）來獲得一個Scala組件。這應該給你的東西模型：

import swing._ 

import javax.swing.SpinnerListModel 
import javax.swing.JSpinner 

object SpinnerDemo extends SimpleSwingApplication { 
    val monthStrings: Array[Object] = Array("January", "February", "March", 
    "April", "May", "June", "July", 
    "August", "September", "October", 
    "November", "December") 

    def top = new MainFrame { 
    title = "Spinner Demo" 

    val monthModel = new SpinnerListModel(monthStrings) 
    val spinner = new JSpinner(monthModel) 
    contents = new FlowPanel { 
     contents += new Label("Month") 
     contents += Component.wrap(spinner) 
    } 
    } 
} 

Answer 2

這並不容易。

[error] /home/ciembor/projekty/VirtualCut/src/main/scala/View/View.scala:22: reference to Action is ambiguous; 
[error] it is imported twice in the same scope by 
[error] import javax.swing._ 
[error] and import swing._ 

swing和javax.swing是相互矛盾的。我想我應該只輸入JSpinner班。
