how to put a console on a JFrame or on graphics window. I thought about simply using a JtextField however I don't have access to the readline command since it appears to me that it is only found in a Console Program. So basically I was wondering how to put up a console on JFrame so I can issue commands on it and watch graphical stuff happen on the same screen(minus where the console box is of course).
View RepliesI have one quick question. If you are extending the acm graphics program, how can you set the location of the entire window? All the set location methods within the graphics program only seem to set the location of graphical objects. I know with JFrames I can use the setLocationRelativeTo(null) to position the JFrame in the center. How to set the location of a graphics window.
View Replies View RelatedI have a question about how to delete only a certain amount of objects on screen in a graphics window. I have a method that will enable me to get rid of every object of the same type off screen, for example this method:
Java Code:
public void deleteTrees() {
//clears all tree trunks and leaves
for (Iterator<GRect> it = historyT.iterator(); it.hasNext();) {
GObject gobj = it.next();
this.remove(gobj);
[Code] ....
That Will delete all trees.
Now In my main method I populate the screen with trees by doing this
Java Code:
for (int xpos = 10; xpos < getWidth() - 40; xpos += getWidth() / 8) {
drawTree(150, 200, xpos, getHeight() / 2.0 - 50);
historyT.add(trunk);
historyL.add(leave);
} mh_sh_highlight_all('java');
My question is how to specify only deleting x amount of trees instead of the whole thing. I pretty sure I need to use something like history.remove(trunk) and to iterate through the amount of trees specified, but not sure how to implement that.
I run this code and a window will pop up, but no graphics :(
I tried to draw a rectangle onto the screen, but it will not show up. I was told to extend JComponent, and I did, but it still does not work.
Java Code:
import javax.swing.*;
import java.awt.Graphics;
import javax.swing.SwingUtilities;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.BorderFactory;
import java.awt.Color;
[Code] .....
launch Java Console window when we enable show console option enabled in Control Panel?

View Replies View RelatedI use Canvas, Graphics & JFrame, but not JPanel, how do I add an Image? To see my code: [Java] package pack.script.game; import java.awt. BorderLayout; import java.awt.Canv - Pastebin.com
What do I need to add, or where can I find information on how to add an image? Can I add an image using Graphics? I will import any utils, swings or awts needed. But I don't want to change my code too much.
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.
We are creating a quiz as a school program, we are using netbeans and we have a little problem. The problem is that our JButton opens a new JFrame in a new window and we want it to stay in the same window. The code we are using is:
private void PlayButtonActionPerformed(java.awt.event.ActionEve nt evt) {
Question1 s = new Question1 ();
s.setVisible(true);
}
Is it possible to make it stay in the same window?
How to remove multiple objects that are onscreen in a java graphics program(specifically the one from the acm library). The clearAll works fine but I would like to keep the background in my frame. I just want to be able to do something like removing all the trees by typing in a phase into a console program. Here is a small snippet of code with details of what I am trying to achieve.
Java Code:
public void command(){
Dictionary dic=new Dictionary();
//dic list of all phases that will either make animations or remove things in a graphical window
String line = readLine("Type here: ");
if (line.equals(dic.clearActions[i])) {
cleared=true;

So I am trying to make my hangman program to show graphics. Here is what I have so far. How do I make my variables in here into a graphics program?

{
public static void main(String args[])
{
Scanner sc = new Scanner (System.in);
Hangman2 gp = new Hangman2();

im wanting to create a console gui that opens with my program game and people can type stuff in it to run commands as well as a debug option to show when errors happen and have a command to list all availble command.
View Replies View RelatedMy task is to create multiuser console chat program. During whole day of poking around , i finally stand on such concept:
1. When running , Server part must stay into while(true) loop and create threads on each ServerSocket.accept() call, providing socket object inside thread. i.e.
while (true){
System.out.println("Waiting for client to connect");
Thread t = new Thread(new Runner(servSocket.accept(),listOfClientSockets));
System.out.println("Starting thread");
t.start();
}
2. Client side always stays within while(true) loop and waiting for user input with ScannerInstance.nextLine() method.
As soon as user prints something and hits enter, data being captured from scanner and thrown to socket output stream to the server.
My question is : if all parties (X clients and server) are actually in waiting mode (server is waiting for connections and each client is waiting for user input), who will refresh the screen for each client to draw the messages other parties sent?
At this time , each party see updates only when he hits enter and while loop does next iteration reading data from buffer and displaying on console.

I am struggling getting my java app to open a console window on either MacOS or windows and run a command. On windows I can get the cmd.exe program to open, but it won't execute the command. On MacOS, I cannot get it to even open the terminal.
String run = "c:
s34bil.exe
elap5.exe" + in + rst + out; //in, rst, out are parameters for the relpa5.exe file.
try {
Runtime rt = Runtime.getRuntime();
rt.exec(new String[]{"cmd.exe","/c",run,"start"});
} catch (IOException ex) {
Logger.getLogger(issrsUI.class.getName()).log(Level.SEVERE, null, ex);
}
I have recently revisited a program I wrote a few years ago, that runs absolutely fine in the console in Eclipse. However, when I export it as a Runnable Jar File, then open the file on my Desktop, nothing happens.How do I get the program to export so that when I open the file, a window opens that acts as the console (so the program can run in it)?

On a side note: for this application, how could you make the program accept a variety of different lengths of strings to perform math with them?

I just started to learn Java Swing and I was trying to make a program that puts 2 images into the Frame window. The code itself doesn't have any errors but when I compile it gives a nullpointerexception, I checked the line with the error and it had to do with my image file but I can confirm the name is correct and I tried both using the path and the name of the image in the package but neither is working.
Error message:

How can I make popup window, which shows the date value when I click a date?
I was working on this project, and I have everything working, except that it doesn't change the colors of the shapes in the other window. Here's the code to see what I'm doing wrong:
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JDemo {
//Global Variables
static Color color0 = Color.blue; //sets the value in the color0 variable to the method Color.blue .
static Color color1 = Color.red; //Sets the value in the color1 variable to the method Color.red .
[Code] ....
The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.
I am new to javafx I start using it instead of swing i used the scene builder for my forms the problem i faced i don't know how to have main screen with menu bar at top and depending the select from the menu it will open other windows and those window must be inside my window just like for example netbeans.
I don't need to open new window in separate i need all windows inside my main window and controlling over them minimize maximize perhaps.

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 {
