well I have an internal frame class that I am implementing an
ActionListener; I have a method that returns information; the problem that
I am having is the content of the internal frame isn't visible; it's just go
to the method that waits for something to return
for example :
public class example extends JInternalFrame implements
ActionListener {
private String value = null;
public example(){
super("Example",false,true,false,true);
Container c = getContentPane();
c.setLayout(new FlowLayout());
JButton ok = new JButton("OK");
ok.addActionListener(this);
JTextArea name = new JTextArea(20);
c.add(name);
c.add(ok);
show();
}
public void actionPerformed(ActionEvent e){
value = name.getText();
dispose();
}
public String getName(){
while(value == null);
return value;
}
}
from the main JFrame
...
example inter_frame = new example();
String result = inter_frame.getName();
