javafx - javafx 1.3 列表视图

Question

我想显示数据库中的数据。javaFx 1.3 中没有 TableView，所以我使用了 ListView。但是，当我将文本框放在列表视图中时，它表现不佳。我在获取数据时遇到问题。谁能给我一个带有文本框的listview代码，它还可以获取和更新数据。

var lv_dept_nm:String = "";

var lv_dept_des:String = "";

var lv_dept_name:TextBox;

var lv_dept_desc:TextBox;

var lv_dept_upBtn: Button;

var lv_dept_flag:Boolean = false;

var lv_dept_ind: Integer;

var lv_dept_len: Integer = 0;

var lv_dept_size:Integer = 0;

function removeLastChar(str: String)

{

    var string;

    if(str != "")
    {
        string = str.substring(0, str.length()-1);
    }
    else
    {
        string = str;
    }
    return string;
}
