How to link JcheckBoxes to JtextFields when they are being dynamically generated?

Question

i want my app to create jcheckboxes from an input that always changes. I want to create a jtextfield near every checkbox, that will be set enabled, only when his checkbox is pressed.

I managed to create this code:

 //Create checkboxes with textfileds
    for (int i = 0; i < activeProjects.length; i++) {
        projectPanels[i] = new JCheckBox(activeProjects[i]);
        projectPanels[i].setSelected(false);
        projectPanels[i].setComponentOrientation   (ComponentOrientation.RIGHT_TO_LEFT);
        projectPanels[i].setAlignmentX(RIGHT_ALIGNMENT);
        projectPanels[i].addItemListener(this);

        projectStorageNum[i] = new JTextField("");
//          projectStorageNum[i].setEnabled(false);
        projectStorageNum[i].setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
        projectStorageNum[i].setMaximumSize(new Dimension(200,30));
        projectStorageNum[i].setMinimumSize(new Dimension(200,30));
        projectStorageNum[i].setPreferredSize(new Dimension(200,30));
        projectStorageNum[i].setAlignmentX(RIGHT_ALIGNMENT);

        tmppnl = new JPanel();
        tmppnl.add(projectStorageNum[i]);
        tmppnl.add(projectPanels[i]);

        checkBoxPanel.add(tmppnl);

    }

and this is my state change listener:

public void itemStateChanged(ItemEvent e) {
Object source = e.getItemSelectable();
JCheckBox myBox= (JCheckBox)source;
String bName = myBox.getText();

if (e.getStateChange() == ItemEvent.SELECTED)
{
// enable matching text field.
// add bName to projects list.
}
    else
    {
     //disable matching textfield
     // remove bName from list
    }

when I access the checkboxes in a dynamic way I don't have access to the second array of textfields. is there any way to link them , or any other idea ?

thanks

Answer 1

One thing you could do is use the setName and getName methods of Component to save the index of the JCheckBox.

projectPanels[i].setName(Integer.toString(i));

Then, in your state change listener.

int i = Integer.valueOf(e.getName());

This gives you the index of the JTextField.
