How To Attach OpenGL Display To JFrame And Dispose Off It Properly
Nov 12, 2014How can i attach the OpenGl display to a JFrame and so that when i close the JFrame is destroys the display? Here is my code so far:
package test.core;
import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Color;
import java.awt.Component;
import java.awt.event.WindowAdapter;
[Code] .....
I had the opengl display attach to the JFrame before i did the runnable. But after adding the runnable the display now shows up the same size as my screen size. I have tried rearranging the
canvas.setSize();
and the
frame.setSize();
but nothing changes the opengl display is still the same size and when i try to close the JFrame first rather then close the display first i get this error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: From thread Thread[AWT-EventQueue-0,6,main]: Thread[main,5,main] already has the context current
which points me to my
Display.destroy();
which im guessing is telling me that i am not properly disposing the display? How to attach the opengl display to the JFrame and fix the error above?

Attempting To Make CoalescedHashMap With Internal Chaining
Apr 3, 2014I am attempting to make a CoalescedHashMap<K, V> with internal chaining. It isn't a hard concept, but it needs to extend AbstractSet and implement Map<K, V>.
Map requires a remove method that returns a V(value). AbstractSet extends Collection, which requires a remove method that returns a boolean value. It gives a syntax error either way it is done. This is a standard homework assignment for a junior level class, so there must be some way to deal with this. It is annoying as we do not need to implement the remove method, it just throws and exception.

Aug 25, 2014I've installed the Java JDK onto my Windows 8 laptop and the first thing I need to do is run the compiler from the Command Prompt. The first prompt I enter is C:java -version.

Java-8 :: How To Manage Untrusted / Unsigned Internal Apps
Apr 10, 2015I'm deploying Java 8 update 40 to my users and want to know if there's a way to manage sites that prompt the user with warnings about untrusted and unsigned applets?
i'm using the exception.sites file to manage applicable prompts/warnings for our internal sites, but doesn't look like the exception list works for untrusted and unsigned.
is there a way to manage these from an all users level, particularly with a deployment (ie, SCCM)?
Modify Internal Object Structure Using Any Design Pattern
Mar 31, 2014I have a design scenario here which is quite interesting and complex. I have a Java class structure as follows,
class A
{
class B;
innerClass B
{
List<class C> listofC;
innerClass C
{
String attribute1;
String attribute2; // Their getter setters
}
}
}
So I have this as an API. Now my challenge is that I need to add one more property to inner class C. i.e attribute3 in innerClass C. I need to do this without disturbing the code in class A by extending these classes or writing a new wrapper, so I can use class C with new properties .
I hope this should be achievable through any design pattern either at runtime or design time.

Frame Not Displaying
Sep 20, 2014I created a instance of a class AddItemView, inside StartUpMenuController. I then passed it into the class, the main method is below showing that as well. However when I do this:
else if(e.getSource()==menu.addBtn)
{
new addItem();
}
I get an error, little red line on the bottom of the text. I am testing the frame at the moment to make sure it is what I want before I move on to the Controller side of it. I just want to display it and go from there.
package mainMenu.Home.DataBase;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import addItemBtn.Home.DataBase.AddItemView;
public class StartUpMenuController
{
StartUpMenu menu;
AddItemView addItem;
[code]...
Not sure if this is the issue but the class I am making a new instance of is in a different package. I imported the package though.

How To Get All Methods On One World Frame
Oct 17, 2014I'm pretty new at java and I was wondering on how to get all my methods on one world frame?
The code is this:
public class TurtleTester
{
public static void main (String[] args)
{
World world= new World();
Turtle turtle= new Turtle(world);
turtle.drawRectangle(50,100);
turtle.drawHexagon(100);
[Code]...
When I run the main method, it would give me a bunch of world frames with one method in each one. I'm using BlueJ btw.

This is my frame class, now I want to be able to change the name of the frame, and get the name with frame.getName() in another class. But I'm not sure how to do this, i tried making a new frame in that class but i feel it's just another frame and not the one i made, also tried something like
public JFrame getFrame(){
this.getFrame();
}
and few variations but it was wrong.
