Swing/AWT/SWT :: Dragging Image Beyond JFrame Limits

Jun 26, 2014

How to drag an image beyond the JFrame limits. In Netbeans, when you drag a Java file editor pane out of the main application frame and onto a second monitor, Netbeans provides a semi-transparent image of the pane you're dragging. I would like to reproduce this effect in my own code. I've been able to do this in a test program (code below) using a glass pane, but cannot figure out a good way to get the image to drag beyond the limits of the main application frame. I looked at the DragnGhostDemo from SwingHacks but it has the same limitation. How this could be accomplished?

In the test application below, click on on the button and drag it's image across the application frame.

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Component;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics;

Swing Program - Show Image On Gray JFrame

Jan 19, 2014

I am trying to make a game with an image on it, and I have one class that gets the image and the other is the game. When I run the program, it just shows my image on a gray JFrame. This leads me to think the image might be covering my whole game, which is weird because it is a mostly transparent image. I have tried resizing it and everything but I don't know what to do..

Here is my image class

Java Code:

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.*;
public class DisplayImage extends JPanel {

Custom Image As The Window In JFrame

Jun 12, 2014

I am looking for a solution that will allow me to use a custom background image to replace the JFrame window. I am able to add a background Image, however I am not able to remove the "white" that is supposed to be transparent.

For example; if the image was shaped like a bird with transparent background (.PNG), I would like that to be put on the JFrame. Usually it will be a square with the image in the middle with white background, which I am unable to remove.

Swing/AWT/SWT :: Image Manipulation - Create Application Where Image Is Displayed On One Label

Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.

Updating Limits For Random Int Values?

May 4, 2014

Write a subclass of BasicGame in which the computer asks the user to choose a whole number from 1 to 100, inclusive. The program then makes a number of guesses. After each guess, the user tells whether the guess is too high, too low, or exactly right. Once the computer "knows" what the correct number is, the computer tells the user the correct number and the number of guesses tried. Have the program ask the user after each game whether she wants to play again. Design the program so that it always guesses the correct answer by the seventh try at latest. Hint: Have two instance variables that keep track of the smallest and largest values that the guess could be (initially 1 and 100). After each wrong guess, update these smallest and largest values appropriately.This is what I have written for the assignment:

Java Code:

import javax.swing.JOptionPane;
public class GuessThatNumber extends BasicGame
{
private java.util.Random randy;
private int itsCompNumber;
private int itsHigh = 99;
private int itsLow = 1;

[code]...

The part I'm having trouble with is changing the high and low values based on the input of "too high" or "too low," which I tried in the continueGame method... When I test the game, the values for itsCompNumber aren't restricted by the user's input at all, and I'm not sure how to fix it.

Add Image On Undecorated JFrame And Make It Translucent By Adjusting Its Opacity

Apr 9, 2014

I'm trying to add an image on an undecorated JFrame and make it translucent by adjusting its opacity. The problem is that my Image also becomes translucent.

Here is my code:

package Loading;
import javax.swing.*;
import java.awt.*;
public class TransparentFrame extends JFrame{
public TransparentFrame(){
createAndShowGUI();

[Code] .....

How can i make my image opaque but the frame behind it completely invisible. Why I'm getting serialize class warning in this code? that is:

"The serializable class TransparentFrame does not declare a static final serialVersionUID field of type long"

Java - Integer Limits / Multiplication And Exponents?

Jan 10, 2014

noticed that if I use integers only and simple multiiplication to get my exponent results (in this instance I was looking into Base 26) what is returned is odd, BUT consistent results once I surpass the integer upper limit of 2,147,483,647. I anticipated that once this limit was reached the program would blow up somehow, but no.

public static void main(String[] args) throws IOException{
// TODO Auto-generated method stub
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter an integer exponent: ");
int i = Integer.parseInt(br.readLine());
CountAlpha ca = new CountAlpha();

Moving Drawn Shape Around By Dragging And Resizing - Functions Do Not Work

Oct 16, 2014

This class is part of a homework assignment and I have a problem:

import model.Model;
import shapes.Rectangle;

I have tried for a week now to get the move-by-dragging and resizing to work, no success. What the code should look like?

Swing/AWT/SWT :: Add A Rectangle To JFrame?

Apr 13, 2014

Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?

Making a JFrame is easy.

Adding a JPanel is a snap.

import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TheJFrame {
public static void main(String[] args) {
// TODO Auto-generated method stub

Swing/AWT/SWT :: Combining Two JFrames Into One JFrame?

Mar 20, 2014

All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class dirtyIceCream extends JFrame {
leftPanel westPanel;
rightPanel eastPanel;
public dirtyIceCream()

[code].....

What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?

Swing/AWT/SWT :: Setting Size Of JFrame

May 26, 2014

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.

import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Swing/AWT/SWT :: Put A Web Page In JFrame Application

Apr 16, 2014

I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :

* import javax.swing . ;

{ public class SwingWebPage
    public static void main ( String args [ ] ) throws Exception {
        JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
        website.setEditable ( false) ;

[code]...

If you test , you'll see that the page is displayed in the JFrame is horrible.
