So I have this line of code...
ioexception11.addChoosableFileFilter(new Jframe());
And when I compile it gives me...
error: constructor Jframe in class Jframe cannot be applied to given types;
ioexception11.addChoosableFileFilter(new Jframe());
This code works
public class RedShapeDecorator extends ShapeDecorator {
public RedShapeDecorator(Shape decoratedShape) {
super(decoratedShape);
}
Below results in an error
public class RedShapeDecorator extends ShapeDecorator {
protected Shape decoratedShape;
public RedShapeDecorator(Shape decoratedShape) {
this. decoratedShape=decoratedShape;
}
So I am guessing that if you extend class, you should use super to pass objects?
I'm getting an error on line 51 and don't know what it means?

So i declared a class in main class but it seems there's error when i compile:
constructor xx in class xx cannot applied to given types
This is my java class:
public class trainer extends person{
String classType;
public trainer(String name, String gender, String address, int id, String classType) {
super(name,gender,address,id);
this.classType=classType;
[Code] ....
And this is the way i declared in main class:
trainer tr = new trainer();
And what i want to do is:
tr.toString();
I am getting an error with my code. How to fix it.

I would like to pass a variable I have in my main to my JFrame. In my main I calculate which pictures I should show in my JFrame. Is it possible to make objects of these pictures in my main class and use them in my JFrame? something like my code below.

I have one question that suppose I am designing a Swing applications and I am using JFrame as Top level container.
So what is best
1)first Extends that class like
public class A Extends JFrame
{
//Do all stuff with Top Level container with gui
}
2)Or design like this from this source
[URL] ....
package components;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/* TopLevelDemo.java requires no other files. */
public class TopLevelDemo {
/**
* Create the GUI and show it. For thread safety, this method should be invoked from the event-dispatching thread.
*/
private static void createAndShowGUI() {
//Create and set up the window.

I have a jFrame and a Java Class. Now i have a path of image in my jFrame which I want to display in java class(Crop2). I created an object in jFrame
Crop2 d=new Crop2();
and then I'm trying to send the data to the class file but it is not working.
I'll start off by showing my full code:
Main class
import javax.swing.JFrame;
public class groupingTest {
public static void main (String[] args) {
groupWindow test = new groupWindow();
[Code]....
At the start of the groupWindow it turns yellow and it says "The serializable class groupWindow does not declare a static final serialVersionUID field of type long".
Right so I have my ItemsPage Jframe Class and I'm trying to pass my TotalPrice variable to my CashPay so I can calculate the change. CashPrice runs and works but when I try run ItemsPage it does nothing I don't even get errors. I tried to remove that small section of trying to pass the variable to CashPay and it worked perfectly so I 100% know that's the problem. This section "public ItemsPage() { Pounds = ""; //super();
Scanner sc = new Scanner(System.in);
CashPay sendTotalPrice = new CashPay();
//System.out.println("Enter your amount");
TotalPrice = sc.nextDouble();
sendTotalPrice.printTotalPrice(TotalPrice);
"

I am making a simple battleship program, you have the menu and click Start to get the board with the bombs (4 buttons as of now) Each button has either a bomb or a defualtbutton. I created my button so it can't be unselected. The problem is I have the button in a Class.java and I want that to close in a period of time. What do you recommend using?

I am working with a program where I am required to use a JFrame in a child class. The only way that I know how to access a JFrame is to do, example (public class Example extends JFrame), but since it is already extending the parent class, I am kind of stuck. I do not think that you can extend two separate classes, so..... I am stuck.
View Replies View RelatedWhat is the difference between extending JFrame in one class and simply constructing a new JFrame object in that same class? What benefits do I have with each solution, providing I want to use that class to create the GUI. Is it the same or are there differences rather than not having to reference to a new JFrame to be able to use its functions?
View Replies View RelatedI'm working on a program using GUI. My problem is that I'm reaching **1000 Line** and this is stressful because all my code are in one file. I'm not liking this. So I research the internet about Inheritance. However, what I know about Inheritance that Inherit everything in the parent class. However, when I try to use a variables in the child class to override it in the parent class I can't for example let say that I have in the parent class something like this:
JButton getButton = new JButton("Enter");
Now when I go to the child class. I want to Inherit and use this variable so I can use the ActionListener on the getButton and override for the parent class, but it's not working.
This is my code:
public class H_Store extends JFrame {
private String s ="Kinds: ";
private JButton calculateButton;
private JPanel mainPane;
private JPanel getProfitPanel;
private JTextField ground_M_QTextField;
[Code] ....
What I want to do exactly is to take the last code into another class or do something with it so I can use it in the Parent class, in other word any math calculation method or class I want them outside the Parent class. I mean this code :
private class CalcButtonListener implements ActionListener{
// vairbles for the ground Meat check box
private double total_GM;
private double weightPrice_1;
private String stringQ;
private String stringW;
private String stringP;
[Code] ....
I got stuck with the error "Unknown class" with the code that I copied from the book ...
import javax.swing.*;
class SwingDemo
{
// create a new JFrame container
JFrame MAIN_FRAME = new JFrame ("A Simple Swing Application");
// give the frame an initial size
MAIN_FRAME.setSize(275, 100);
// terminate the program when the user closes the application
MAIN_FRAME.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
[code]...
The error comes from lines 21 and 27.
21 MAIN_FRAME.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
27 MAIN_FRAME.add(FIELD_LABEL);
I have tried to rewrite from scratch and still gets the same error.
I've been trying to pull data from another class file "Calculations.java" and have it be displayed in a TextField in "DataAnalyzerGUI.java". Here is how the hierarchy is broken down for my assignment:
DataAnalyzerGUI.java extends JFrame
ReadFiles.java extends DataAnalyzerGUI.java
Calculations.java extends ReadFiles.java
Everything displays and functions correctly in a command prompt if I use a line like this:
System.out.println ("Lowest opening " + dateArray[lowestOpenIndex] + ": " + dataArray[lowestOpenIndex][2]);
But trying to get it to display in a GUI has been quite troubling.
I know the code is supposed to look something like this:
dataOutput.setText(DESIRED CODE HERE);
But I am unable to find anything of value to work out.
I have attached my complete project....

how we call a jFrame from another jFrame .
View Replies View RelatedI have a swing jFrame set up with a control group which contains 3 radio buttons.
When one is clicked it sends its label to a jtextfield in a different class i have code parsing text by a term

s.useDelimiter("*");

I just need to know how to access the jframe variables (textfields, panels and such) so i can use their inputs in code to filter a text file.
**Getting data on from rfid scanner as Serial rs232 port in JFrame**, in this case I have made a JFrame form and I have a JTextField for storing data rfid as a String. Actually, I found a class from internet that read the RFID reader as byte, now How To get data from my RFID Class to my JTextfield Jframe in my main class as String?
Here my RFID class :

I've used Netbeans IDE to create a simple Swing JFrame container, class NewJFrame.
NewJFrame calls another JFrame with dialog in it. Problem is there is an endless call made to it. Here's the issue relevant piece of code:
//Code for calling class
package p;
public class NewJFrame extends javax.swing.JFrame implements ActionListener {
.........
public NewJFrame() {
initComponents(); //IDE auto generated code for binding
[Code] ....
I searched but i cannot understand why run class is getting called multiple times. I have attached the screen prints for both the screens. 2nd screen print(of called class) is very shallow since screen was blinking unstopped due to multiple calls, but i have attached a faint image of it.
