I use the following code for changing the properties of a JTextField. It worked properly. My problem is how to change the JTextField properties by passing parameters without using the default functions. For example if I want to change the JTextField LEFT property means using parameter (control name,left,100) like this. How do I change a JTextField property by passing parameters to the JTextField Property using the following code?
package textfield;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class textf implements ActionListener
{
JTextField txt;
JButton width;
JFrame frame;
JPanel panel;
//Font font = UIManager.getFont("txt.font");
public textf()
{
frame=new JFrame();
panel=new JPanel();
txt=new JTextField(10);
width=new JButton("width");
width.setBounds(20, 200, 50, 40);
panel.add(txt);
panel.add(width);
width.addActionListener(this);
frame.add(panel);
// n.getContentPane().add(new textf());
frame.setSize(440,310);
frame.setVisible(true);
}
public void actionPerformed(ActionEvent e)
{
txt.setBorder(BorderFactory.createLineBorder(Color.red));
txt.setHorizontalAlignment(javax.swing.JTextField.LEFT);
txt.setSize(100,100);
txt.setPreferredSize(new Dimension(1000, 90));
txt.putClientProperty("txt.sizeVariant", "small");
txt.setFont(new Font("Comic Sans",Font.ITALIC,20));
txt.setForeground(Color.BLUE);
txt.setHorizontalAlignment(JTextField.RIGHT);
}
public static void main(String[] args)
{
new textf();
}
}
我想您想设置JTextField的位置(如果没有,请解释一下“ LEFT”属性的含义)
tf.setBounds(LEFT,tf.getY(),tf.getWidth(),tf.getHeight());
