Groovy Swing buider fileChooser

我想使用groovy swing builder的fileChooser沒有運氣。當我從複製常規網站下面的例子：Groovy Swing buider fileChooser

def openExcelDialog = SwingBuilder.fileChooser(dialogTitle:"Choose an excel file", 
           id:"openExcelDialog", fileSelectionMode :   JFileChooser.FILES_ONLY, 
           //the file filter must show also directories, in order to be able to look into them 
           fileFilter: [getDescription: {-> "*.xls"}, accept:{file-> file ==~ /.*?\.xls/ || file.isDirectory() }] as FileFilter) {

}

但我得到一個錯誤信息：

groovy.lang.MissingMethodException: No signature of method: static groovy.swing.SwingBuilder.fileChooser() is applicable for argument types: (java.util.LinkedHashMap, ConsoleScript19$_run_closure1) values

不能使用的文件選擇一個這樣的SwingBuilder之外。相反，您只需使用普通的非swingBuilder JFileChooser。下面是一個完整的工作示例：

import javax.swing.filechooser.FileFilter 
import javax.swing.JFileChooser 

def openExcelDialog = new JFileChooser(
          dialogTitle: "Choose an excel file", 
          fileSelectionMode: JFileChooser.FILES_ONLY, 
          //the file filter must show also directories, in order to be able to look into them 
          fileFilter: [getDescription: {-> "*.xls"}, accept:{file-> file ==~ /.*?\.xls/ || file.isDirectory() }] as FileFilter) 

openExcelDialog.showOpenDialog()

注意，new JFileChooser只是在右括號結束 - 有沒有尾隨關閉。

解決方案：

OLD：fileFilter: [getDescription: {-> "*.xls"}, accept:{file -> file ==~ /.*?\.xls/ || file.isDirectory() }] as FileFilter

NEW：fileFilter: [getDescription: {-> "*.xls"}, accept:{file -> file.toString() ==~ /.*?\.xls/ || file.isDirectory() }] as FileFilter

[Win7的（64）的Groovy版本：1.8.3 JVM：1.6.0_29）]

我認爲你需要先創建一個SwingBuilder對象。這工作對我來說：

def swing = new SwingBuilder() 
def dialog = swing.fileChooser(dialogTitle: "Open A File") 
if (dialog.showOpenDialog() == JFileChooser.APPROVE_OPTION) { 
    println dialog.selectedFile 
}

看here瞭解屬性的完整列表。
