从其侦听器中的JComboBox中删除元素

Question

I have a combobox, with certain elements within it, eg: "abc", "pqr", now when the user types "a", I wish to refresh the combobox and remove all its elements and then again add only those elements which start with the user string. (These elements are stored in a array)

I tried in to modify its elements in "addCaretListener" but it throws "java.lang.IllegalStateException: Attempt to mutate in notification" Exception

Is there a specific way to implement this?

Thanks

Answer 1

考虑使用两个JComboBox或Autocompleted JTextField加上JComboBox （而不是你描述的请求），你必须从JTextField获取所有突出显示的Chars（仅创建与过滤Item相同的方法的构造函数）并动态更新ComboBoxModel

I think you create the AutoComplete combo see this example
