通过将参数作为组件名称返回JTable的函数 [英] Function returning the JTable by taking parameter as a Component's Name

问题描述

public JTable getTable(String Component_name)
    {
        JTable table=new JTable();
    //in this function i want to search all the JTables that have been created on runtime! 
    //and then i want to return one JTable by the name "Component_Name"//

        return table;
    }

这就是我希望我的功能能够做到的；我想出了一种创建具有私有JTable表和私有String名称的Components新类的解决方案，但是按名称搜索JTables仍然存在问题.

This is how i want my function to be ; i came up with a solution of creating a new class of Components having private JTable table and private String name, But still problem comes up at searching JTables by name.

推荐答案

成功回答！

我创建了 私有ArrayList List = new ArrayList();

I created private ArrayList List=new ArrayList();

并在我的ActionListener中::

and in my ActionListener::

 AddTableMenuItem.addActionListener(new ActionListener() 
    {
                //This method will be called whenever you click the button. 
            public void actionPerformed(ActionEvent e){
               Table table=new Table();

              JTable.setName("Table"+count);

              AddT(table);                               // Table List 
    }

其中

  public ArrayList<JTable> getTable()
  {
        return List;
  }

 public void AddT(JTable tl)
 {
     if(tl.getName()!=null)
     {getTable().add(tl);}
     else return;
 }

现在我有一个所有JTable的列表，现在我可以按名称实现来获取它们了，如下所示:

Now i have a List of all JTables that now i can fetch by names implementation as follows::

JTable one= new JTable();
  JTable two= new JTable();
  ComboBoxModel combo = comboBox.getModel();

 for(JPanel t: getTable())
  {  
       if(combo.getSelectedItem().equals(t.getName()))
       {
          one=t;
       }
  }
