How to define the length of a JTextField by using the RiverLayout - a simple and flexible Java Layout Manager- and the JGoodies binding
sample:
imports :
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.beans.PropertyChangeListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import com.jgoodies.binding.adapter.BasicComponentFactory;
import com.jgoodies.binding.beans.BeanAdapter;
import com.jgoodies.binding.beans.ExtendedPropertyChangeSupport;
import com.jgoodies.binding.value.ValueModel;
import se.datadosen.component.RiverLayout;
...
public Container formRiverLayout(JFrame f) {
okButton = new JButton();
okButton.setText("ok");
okButton.setActionCommand(CMD_OK);
okButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
// windowAction(event);
System.out.println("ACTION : BUTTON OK WAS CLICKED");
System.out.println(okButton.getActionCommand());
}
});
Registration bean = new Registration();
BeanAdapter adapter = new BeanAdapter(bean, true);
ValueModel nameModel = adapter.getValueModel("username");
ValueModel ageModel = adapter.getValueModel("age");
ValueModel commentModel = adapter.getValueModel("comment");
JTextField userinput = BasicComponentFactory.createTextField(nameModel);
JTextField ageinput = BasicComponentFactory.createTextField(ageModel);
ageinput.setColumns(3);
// When this configuration isn't done the BasicComponentFactory
//will not configure the width and the JTextField will be redused to
//a few millimeter.
JTextArea commentinput = BasicComponentFactory.createTextArea(commentModel);
Container c = f.getContentPane();
c.setLayout(new RiverLayout());
c.add("right", new JLabel("Registration form"));
c.add("p left", new JLabel("Name"));
c.add("tab hfill", userinput);
c.add("br", new JLabel("Age"));
c.add("tab", ageinput);
c.add("br vtop", new JLabel("Comment"));
c.add("tab hfill vfill", new JScrollPane(commentinput));
c.add("p center", okButton);
return c;
}
