pro_java thread: Question on storing variables ???


Message #1 by Guerrino Di Minno <GDiMinno@h...> on Fri, 14 Sep 2001 14:41:47 -0400
Here is an example that would use a TextField component for the name entry,
and a label to re-print the name on the screen.  This example shows AWT
components.  There are similar things for Swing components.

To define the TextField, you would do something like this:

TextField myTextField = new TextField();

To store the value of the text field in another variable, such as a string,
you could do something like this:

String myString = myTextField.toString();

To copy the value from the string variable to a label elsewhere on the form,
you could do something like this:

Label myLabel = Label(myString);

or

Label myLabel = Label();
myLabel.setText(myString);

or

Label myLabel = Label(myTextField.toString());

or

myLabel.setText(myTextField.toString());


There are a variety of ways to do what you are asking.  Each component
usually has a method for getting its value, and many of the text based
things have a "setText" method for setting its value to something.

Hope that helps.
