JFrame quase modal

Assuntos Gerais
#1

Usando o fundamento “Java sempre passa por valor”. Consegui um JFrame quase modal sem usar o JDialog.

[code]import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class JFrameNormal {
private JFrame jf;

public JFrameNormal() {
	JButton jb = new JButton("abrir um JFrame quase modal");

	jf = new JFrame("JFrame normal");
	jf.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
	jf.setSize(400, 400);
	jf.setLocationRelativeTo(null);
	jf.add(jb);
	jf.setVisible(true);

	jb.addActionListener(new AbreModalFrame());
}

public void setModal() {
	jf.setEnabled(!jf.isEnabled());
}

private JFrameNormal getThis() {
	return this;
}

private class AbreModalFrame implements ActionListener {

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		setModal();
		new JFrameQuaseModal(getThis());
	}
}

}
[/code]

[code]import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class JFrameQuaseModal {
private JFrame jf;
private JFrameNormal jfn;

public JFrameQuaseModal(JFrameNormal jfn) {
	this.jfn = jfn;
	JButton jb = new JButton("Fechar");

	jf = new JFrame("JFrame quase modal");
	jf.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
	jf.setResizable(false);
	jf.setSize(300, 300);
	jf.setAlwaysOnTop(true);
	jf.setLocationRelativeTo(null);
	jf.add(jb);
	jf.setVisible(true);

	jb.addActionListener(new Fecha());
}

private class Fecha implements ActionListener {

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		jfn.setModal();
		jf.dispose();
	}
}

}
[/code]

[code]public class TesteFramequaseModal {

public static void main(String[] args) {
	JFrameNormal p = new JFrameNormal();
}

}
[/code]
