THX, I've modified you're code a litle bit and found what I was looking
for..
So, I'm new in swing (new also in Java :-) ) and I was wondering....
I'm creating one let's call it aplication, with few buttons, TexFields,
RadioButt., comboBox...
right now, I'm creating classes for each component like:
class T1A implements ActionListener {
public void actionPerformed(ActionEvent e) {
tf1.setText(tf2.getText() );
}
}
and calling it with tt2.addActionListener(new T1A());
and now I have to code at least 10 new classes, is there any other way?
at the moment I'm learning, and I'm coding each line, not using any GUI
builder...and that's a
lot of code to write.. ;-)
In Java, there is something called an anonymous inner class.
tt2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
tf1.setText(tf2.getText() );
}
});
Oh, and a note on style. It makes it a lot easier to
edit/debug/fix/maintain/describe your code if you use meaningful names.
tf1 is obscure, it should be named something like
"emailAddressTextField" where "emailAddress" is the "function" of the
text field.
names like tt2, tf1, tf2, all start to look the same after a while, and
if you're like me and continue coding after you start to get tired,
you'll start putting tt1 instead of tt2, etc.., and it can be difficult
to figure out where your mistake is.
