javafx 1.3 listview

Question

데이터베이스의 데이터를 표시하려고합니다. ListView를 사용하기 때문에 javaFx 1.3에는 TableView가 없습니다. 그러나, 내가 listview에 텍스트 상자를 넣을 때, 그것은 잘 수행되지 않습니다. 데이터를 가져 오는 데 문제가 발생합니다. 아무도 내게 그것의 텍스트 상자와 listview에 대한 코드를 줄 수 있고 그것도 가져오고 데이터를 업데이 트하십시오.

var lv_dept_nm:String = ""; 

var lv_dept_des:String = ""; 

var lv_dept_name:TextBox;

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);
