如何在tornadofx中实现自动完成组合框

import tornadofx.*
import javafx.collections.FXCollections
import javafx.scene.control.ComboBox
import javafx.scene.control.TextField

class AutoCompleteComboBox<T>(items: List<T>) : ComboBox<T>() {
    private val data = FXCollections.observableArrayList(items)
    private val filteredData = FXCollections.observableArrayList<T>()

    init {
        // 设置自动完成模式
        isEditable = true
        // 绑定过滤后的数据到组合框
        setOnKeyReleased { handleKeyReleased() }
    }

    private fun handleKeyReleased() {
        val searchText = editor.text
        filteredData.clear()
        // 根据输入的文本过滤数据
        filteredData.addAll(data.filter { it.toString().contains(searchText, ignoreCase = true) })
        // 设置过滤后的数据到下拉列表
        items = filteredData
        // 显示下拉列表
        show()
    }
}

class MyApp : App(MyView::class)

class MyView : View() {
    private val items = listOf("Apple", "Banana", "Cherry", "Durian")
    private val autoCompleteComboBox = AutoCompleteComboBox(items)

    override val root = vbox {
        label("Select a fruit:")
        add(autoCompleteComboBox)
    }
}
