Swing/AWT/SWT :: Open GUI On Top Of Another GUI
Feb 12, 2014
how to open a GUI on top of another GUI? I have built a GUI and have a button that when pressed I want to open a new GUI which is another java application within the project, it seems pretty straight forward and I just need to insert 'new [name of application]()'
Button btnEdit = new Button(shell, SWT.NONE);
btnEdit.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
new edit();
}
});
btnEdit.setBounds(76, 10, 75, 25);
btnEdit.setText("Edit");

I'd like open a second GUI when I press a button that's on the first GUI, like a link in a website.
What I want to do is:
1- Open GUI_1;
2- Press a button on GUI_1; this button close GUI_1 and open another GUI (GUI_2).
How can I do it?

I downloaded JDK 7 file. But, I don't know how to use it. First of all, I even don't know how to open it.
There are some files in 'Java development kit', and the one I can play with is 'Java mission control'.
But it looks strange to me...and it looks it is not the way.. I want to compile files but, I can't find how to open java compiler.

i have an older file I was working on 2 months ago and when i try to open it in eclipse I get a message corruption error. I know this is not possible since I was just working on it a while back, and it's the same program version as what i am currently using..Or would I do a file import instead?

I am new to EJB; I am writing EJB (3.1) program in JBoss 7.1 - I am using MySQL DB with JPA. While executing the program, I am facing the Generic JDBCException: Could not open connection. It is happening only for certain tables in the database; but NOT for all tables. My code is able to access few of the tables in the same database. Here is my full stack trace: -

Is there a way we can open a .chm file stored at server through jsp application without downloading the file and saving it to the local machine.
What I googled is : we cannot download .chm files from a web browser and simply click Open. Download the .chm file to your computer first, right-mouse click it in Windows Explorer and select Properties. Then click Unblock.
But I want my users to simply view the file without downloading it.

What does this error mean, and also, when I get it, the command line hangs so that I can't do anything else (Is there a way to recover from that?). I'm running Windows 7.

In Windows and Mac both, the following code works wonders:
Java Code: // openURL called from another method
openURL("http://www.google.com");
private void openURL(String URL)
{

The only OS I can get this to work on is Kubuntu or even Ubuntu for that matter.

I was just wondering how would I create a jar file that would open 3 other jar files when I open the jar file with my batch file it and when I type stop in the batch file it will out put the stop command into all 3 of the other jar files.
This is for my Minecraft server so I can launch them all at the same time and inStead of having to enter the commands in all the server batch files I just have to do the command in 1 I know their is things like multi craft to do this but I want the code so I don't have to use multicraft.

I am trying to get RJDBC to work so I can connect to Oracle from R doing some data analysis..
This connection string works for my local db which I have it running in my Virtual Box
con <- dbConnect(drv, "jdbc:oracle:thin:@//localhost:1521/orcl", "demo", "demo")
However, it does not work when I do it for the remote db that I really need to pull data from...

This isn't asking to make a Singleton, where I want only one type of a type of window period.
It's not where I want only one instance of the program itself open at a time. It's more along the lines of, though I don't care if there is more than one Microsoft Word open at the same time, I don't want more than one instance of blablabla.docx to be open at once.
In other words, I'd need to scan my system or my list of open windows of a particular type to make sure that no two ones where equals is true will match up.
I was going to do it to associate it with a particular name with a window (it's sort of an addressbook, though not quite.) I'd use a JFrame subclass to make these windows that have a name go with them. For now, unless I find the great need for this project that there might be someone with the exact same name around here, I'm going to use equals() with name on this. I can type cast and whatnot.
However, how do I get to know what windows are open at once so I can check all my list of open windows, and I'd prefer to check only ones of certain types, though I may have to check them all indirectly perhaps, before I check the names.
I'm wondering is it a getChildren() of the main window or something else? How do I know what all of my open windows are?
I'd prefer to have to check as few as possible and not have to check unnecessary ones.
As for the structure of my thing that would click that would open the new window, I'm not sure yet. I'm almost leaning JLabel, though it's a bit less sophisticated, as it might be more difficult to add to a JList (maybe I"m wrong on thinking on that. It's been a little while since I last worked with JLists.)
(I think I can set list data, but the problem is, even using an ArrayList, it only takes an array for this as a param and ArrayList returns an Array of type Object, which means a lot of pesky type casting every time just to add or remove a name.)
It does have Vector, but I thought Vector was being phased out.
Anyway, without having too much code given, as I'm not sure how I'll set this up yet, how do you get access to all of the windows being opened to be able to check them for certain traits?

I have Java 6 and Java 7 installed, if i open an applet in any browser it uses the dll's and from the jre7 folder. I would like it to use the jre6 folder, without uninstalling java7. I tried doing this through the java control panel by adding jre6, checking it as enabled and checking off jre7. It didn't make any diffrence.

I am trying to write a java code for a homework problem in my intro java class but im having problems. This is the problem:
Write a program that open the MyFile.txt and read from a file with these criteria.
1)-The program should display the first five lines of the file’s contents only.
2)-If the file contains less than five lines, it should display the file’s entire content. You must check for end of file and less than 6 lines on the loop iterations.
3)- your program should use loop to read the line by line of the file MyFile.txt.
The serperate myfile.txt has this
I can still remember, at the end of that year, we sat for the last time in our circle together. She played us her favorite song, "like a bridge over troubled water" and quietly passed out a gift she had made for each of us.She had made each of us a pottery heart with our name and the date on it on the back each read "I believe in ME".We all cried including her. She told us she would always remember US. We believed she would.
and this is what the code is suppose to look like after you run it : Java33.png
And this is what i have so far : Java22.png
what needs to go next to complete the javascript to show the first 5 lines of the text files?

I have looked over other people code relating to files that are related to my actual studies in class. My teacher hasn't worked on a lot of file problems so I want to gain some understanding on it.
1.) I have this class with variables declared
import java.io.*;
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
I'm aware that having a private variable would not allow that variable to be accessed outside the code. Vice versa, public variable would do that. The FileWriter and the File Inputfile is something I don't understand, especially have them in classes. What is the purpose of them?
2.)
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
[Code] ....
I have made this code here that opens the output and input file. If I make another method, how would I display the text onto that same file. Hard to clarify for me, but in each method do I just keep creating :
FileWriter outputfile=new Filewriter(filename)

I want to design an open-answer quiz game using Java. Basically, the plan is to design a quiz where the name of a medicine is displayed as "the question" and the player will need to input the unique code (as "the answer") of the medicine in an open box (all the codes are two characters). The list has about 204 named medicine (with potentially more to be included at a later stage). The questions will not appear in the same order for each session restarted; they will appear randomly.
The player will have 60 seconds, and for each correct answer, will score 1 point and add 2 seconds to the timer. The player will also have 6 "lives", and for each incorrect answer, the player will lose a life, with no effect on the time.
The idea of the game is that the player memorise as many of these medicine codes as possible.

I have a question and wasn't able to find what I needed through the search. I am currently using Netbeans 8.0 and working on a desktop app. I have a main GUI file where I am going to add a menu item that can be clicked to open up an "About" Dialog box. The problem is, I don't know how to do this
The file are...
MainGui.java
About.java
How would I go about opening the About.java when clicking on a menu item? I tried using...
new About();
About.setVisible(true);
But this just gave a compilation error.

I'm making a tic tac toe program. Currently I have a welcome screen for my tic tac toe game, once the button is clicked I want the main game to open. I have created two FXML VBox windows created from JavaFX Scene Builder. I want to know how to close the welcome menu and launch the 2nd FXML window.
This 2nd FXML window will have it's own controller where the tic tac toe calculations will be held.
Here is the event listener on when the mouse action is performed on the button
@FXML
private void startGame(ActionEvent event) {
}

I have recently taken up some java after a period of time learning batch scripting. the issue I have run into is that my build compiled and ran just
fine when invoking from within the netbeans IDE but after that I 'cleaned and built' the jar and the IDE stored it in the directory that I specified while installing.
I went to that folder, double clicked on my gui and go nothing. So then I opened a command prompt did, "java -jar myapp.jar" and got the following of which has me completely lost:
Exception in thread "AWT-EventQueue-0" javax.persistence.PersistenceException: No Persistence provider for EntityManager named
