Question

我试图在一个类中定义我的常规FX框架“框架”。然后，我有一个执行“ frame.setenabled（false）”的按钮，但是由于某种原因找不到“ frame”。

我的代码：

class Contact_Books extends JFrame {
  public Contact_Books() {

    @Grapes([
        @Grab(group='org.xerial',module='sqlite-jdbc',version='3.23.1'),
        @GrabConfig(systemClassLoader=true)
    ])

    def sql = Sql.newInstance("jdbc:sqlite:Contacts.db", "org.sqlite.JDBC")

    def contact = sql.dataSet("Contacts")


    //Define Fonts
    Font title = new Font("Serif", Font.BOLD, 30)
    Font sub_title = new Font("Serif", Font.BOLD, 17)
    Font Name = new Font("Serif", Font.BOLD, 20)
    Font Ok_Button = new Font("Serif", Font.BOLD, 15)
    Font Contact_Add_Button = new Font("Serif", Font.BOLD, 15)
    Font bottom_buttons = new Font("Serif", Font.BOLD, 14)



    def result = sql.firstRow('select count(*) as cont from Contacts WHERE name != "none"')
    long Number_Of_Contacts = result.cont

    def swing = new SwingBuilder()
    def frame = swing.frame(title: "James' Contact Book", pack: true, visible: true, defaultCloseOperation: WC.HIDE_ON_CLOSE)
        {
          panel(id: 'mainPanel') {
            scrollPane(verticalScrollBarPolicy: JScrollPane.VERTICAL_SCROLLBAR_ALWAYS) {
              vbox {
                label(" You have $Number_Of_Contacts contacts", constraints: "align center, span 6").setFont(title)
                label("  Press more to see more information").setFont(sub_title)

                (0..Number_Of_Contacts + 100).each { num ->

                  def pane = panel(alignmentX: 0f, background: java.awt.Color.LIGHT_GRAY, layout: new GridLayout(1, 2)) {
                    sql.eachRow("select rowid, * from Contacts WHERE rowid = $num+1") {
                      if ("$it.name" != 'none') {

                        label("   $it.name").setFont(Name)

                      }
                      if ("$it.name" != 'none') {
                        more = button(id: "buttonpanel$num", text: "More", actionPerformed: {
                          frame.setEnabled(false);

我的初始化代码是：

  public static void main(String[] args) {
    new Contact_Books();
  }

我不确定是否因为frame是一个对象而需要使用self？看来我对frame变量的定义超出了我尝试使用它的范围。

任何帮助，谢谢。

您应该简单地从实例中拆分声明：

def frame
frame = swing.frame(...)

类，常规FX和调用自我
