Don't think you can with a JTextArea (without writing your own View). But you can with a JTextPane. This example uses center alignment but can easily be changed to right alignment:

> and JComboBox

The renderer is a JLabel so you just need to create your own renderer and set the alignment of the label text to be right aligned.

this might start you off

import javax.swing.*;

import java.awt.*;

class Testing extends JFrame

{

public Testing()

{

setLocation(300,200);

setDefaultCloseOperation(EXIT_ON_CLOSE);

JTextArea ta = new JTextArea();

ta.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

JScrollPane sp = new JScrollPane(ta);

sp.setPreferredSize(new Dimension(200,150));

JComboBox cbo = new JComboBox(new String[]{"abc","123"});

cbo.setEditable(true);

cbo.setRenderer(new RightAlignRenderer());

//cbo.getEditor().getEditorComponent().setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

((JTextField)cbo.getEditor().getEditorComponent()).setHorizontalAlignment(JTextField.RIGHT);

//above two lines for editable combo box, seems to be the same either way

getContentPane().add(sp,BorderLayout.CENTER);

getContentPane().add(cbo,BorderLayout.SOUTH);

pack();

}

public static void main(String[] args){new Testing().setVisible(true);}

}

class RightAlignRenderer extends DefaultListCellRenderer

{

public Component getListCellRendererComponent(JList list,Object value,

int index,boolean isSelected,boolean cellHasFocus)

{

JLabel lbl = (JLabel)super.getListCellRendererComponent(list,value,index,isSelected,cellHasFocus);

lbl.setHorizontalAlignment(JLabel.RIGHT);

return lbl;

}

}

Interesting. I did my test like this and the text originally displayed on the left. When I typed the first character it then shifted to the right.

JTextArea textArea = new JTextArea(5, 40);

textArea.setText("Some\n text");

textArea.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

But it works fine like this:

JTextArea textArea = new JTextArea(5, 40);

textArea.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

textArea.setText("Some\n text");
