More Info About the Breezy Boxes
(Working with String input and set precision.)
If you want the user to type String data
in the Breezy response box:
. . .
// This program expects user to type his/her name in
response
// - - then enter age.
// The information will be displayed in a message box.
public class SampleProgram extends GBFrame
{
Label nameLabel = addLabel ("Name",1,1,1,1);
Label ageLabel = addLabel ("Age",2,1,1,1);
TextField nameField =
addTextField ("",1,2,1,1);
IntegerField ageField = addIntegerField (0,2,2,1,1);
Button computeButton = addButton ("Display",3,1,2,1);
public void buttonClicked (Button buttonObj)
{
String name, outputString;
int age;
name =
nameField.getText();
age = ageField.getNumber();
outputString= "Name: " + name + "\n"
+ "Age: " + age + "\n";
messageBox(outputString);
}
public static void main (String[ ] args)
{
Frame frm = new SampleProgram();
frm.setSize (200, 150);
frm.setVisible (true);
}
}
If you want to display a specific number of
decimal places in a Breezy box:
. . .
// This program takes a dollar amount from user
// and
converts it to pesos.
// Information will be displayed with two decimal places.
public void buttonClicked (Button buttonObj)
{
double dollar, peso;
peso = PesosField.getNumber();
dollar = peso/10.2;
DollarsField.setNumber(dollar);
DollarsField.setPrecision(2);
}
|
TextField nameField =
addTextField ("",1,2,1,1);
Be careful when entering this line. The correct entry
is "" (right tight together) and not " " (with a space in
between). If you put in the space, you will need to type a
space at the end of the string being entered in the Breezy box
for it to be recognized correctly. |
If you want to give
your Breezy box a title:
 |
Notice that
this Breezy box has a title up in the blue area
at the top. To create a title, simply add
one line of code in main. |
public
static void main (String[ ] args)
{
Frame frm = new OuncesPounds ();
frm.setSize (250, 150);
frm.setVisible (true);
frm.setTitle("Ounces to Pounds");
}
