so the dialog has its owner frame, which is neccessary but i want the dialog has another icon ,or remove the icon on the dialog how may i do ?
I have a question regarding the permissions set for generated heap dumps.
I have some Jetty servers running on Linux (Java 6 64 bit / Java 7 64 bit) with the following Java arguments:
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/opt/apps/heapdump
When there is a out-of-memory exception a heap dump is automatically generated by the JVM. But it seems that the heap dump permisions are set to read-write for owner only (600).
When I create files then they have by default read-write for owner and group/all read access (644).

We are asked to create a JDialog showing our database. I am able to show the database but i can't seem to position the heading panel, table and back button. My back button is also not showing up. Here is part of my code...
import java.awt.Color;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.sql.*;
import javax.swing.*;
[Code] ....
All the samples I found use JOptionPane to return a single value. I am looking to return two values from two Text fields.
View Replies View Relatedhow the entire application could be close when you click on X in a JDialog Box. I have tried
System.Exit (0)
but it only close the Dialog box
This is my code:
JDialog dialog = new JDialog();
dialog.setSize(400, 150);
dialog.setTitle("Input dialog");
dialog.add( new JLabel("simtime(min)") );
dialog.add( new JLabel("interval(sec)") );
dialog.setVisible(true);
The problem is that the two lables replace each other.How to position them where we want?
Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?
View Replies View RelatedI have a practice exercise here wherein I will add a JOptionPane to a program. When the close button is clicked, the JOptionPane will appear asking the user to exit the program. If the user clicks "Yes," it'll, of course, close the entire program and not just the JOptionPane, but if the user clicks "No," it will return to the program. Please refer to my code below:
try
{
output = new DataOutputStream(new FileOutputStream("ProjSixExe4.dat"));
}
catch(IOException ex) {
this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING))
}
final JOptionPane optionpane = new JOptionPane("Are you sure you want to quit
this program?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
The exercise said it must be placed before the EXIT_ON_CLOSE portion.
I have JFrame and when I click a button which is in frame JDialog is opened. Now,how can I refresh JFrame when close JDoalog?

I show a JDialog window and this window has 3 buttons when I press one of them it should close the window, how do I do that?
View Replies View RelatedI have a program that using one JFrame which opens one of two JDialog windows depending on which button is pressed.
How do I assign listeners to the buttons and fields on the JDialog window? I added listeners on the View end, but how do I process them? I tried adding the '..implements ActionListener" class in the main Controller but it does not recognize/hear anything.
With the MigLayout for Swing, I'd like to see the JDialog looking like the standard windows Dialog,where to have the OK and cancel buttons at the lower right corner.
View Replies View RelatedSo I'm in the middle of creating a model program with voxels. I want to be able to see how the model looks like when I'm in for example my documents (not inside the real program). I want it to show an image of the model, just like a png file shows its image. I've tried looking around, but I've only found threads about changing exe files icon.
Image example:
So, is this possible in Java or do I need to use c/c++ (with JNA) to make this possible?
Or is it not possible at all?
So I have got a button and there is this property assigned to it:
button.setIcon(new ImageIcon("srcimage.jpg"));
The icon is not displayed in full, as it is larger than the button. What property can I use to resize the icon? I have tried few and it did not work.
Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:
try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}
Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.
How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.
Here is the whole code...
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;
[Code] ....
Any way to resize an ImageIcon when placing it on a Button so that I don't have to physically rezize the image file?? I am writing an Application, not an applet, so the getImage method won't work.

I want the Jbutton Button1 icon to change when i click it howerer i am getting the error can not find symbol for the code in the actionPerformrd method.
I have a problem I must solve and could not find an answer after a couple weeks of research, so here I am. I have created a custom Table Cell Renderer than extends DefaultTreeCellRenderer. The mission of this renderer is to set the branch icons depending on conditional statements. There are 3 conditions, and each one should render a different icon. These conditions must be tested against all branches in the tree. This means that using something like setOpenIcon() and setClosedIcon() will not work since it seems as though these methods set all branches to a specific icon (I could be wrong about that though). Below is the code for my custom. I made comments so it is easier to understand what I want to happen and what is not happening.
/**Custom Cell Render that will set the icons for the tree branches and the leafs*/
private TreeIconCellRenderer extends DefaultTreeCellRenderer{
public Component.getTreeCellRendererComponent(JTree tree, Object value,boolean selected,boolean expanded, boolean leaf, boolean row, boolean hasFocus){
//Get defaults in case there is no need to renderer
[Code] ...
What I really need to know is why the renderer is not differentiating between the leaves and branches. The logging statements I have added confirm that the branch block of code does not execute.
Why the label wont show the file. The file is located within the project.

View Replies View RelatedI'm working on making a game in JAVA. To be brief, the game is on a 6x6 matrix called "blocks[][]". The game has two players and the objective is to capture the enemies pieces by moving your piece onto there's. The players do this by moving one piece per turn either forward/backward (Vertically) or right/left (horizontal) movements. Essentially checkers without jumps.I'm not very far into the development process here. So far I have the game board created and the pieces load by clicking the "Start" button (handled by the refresh function). However I'm having a few problems... Namely moving the pieces effectively at the moment.
Right now there's a lot to do:
(1) - Implement a turn system,
(2) - Only allow a player to click their pieces (I've a validation function already in place to only permit valid moves [horizontal/vertical only]),
(3) - getting the pieces to actually "move" what I mean by this is a player selects the piece they want to move, then they select the spot they want to move to and the icon I have placed on the button is supposed to be added to the new square and the icon for its previous position is to be made null.
Please see the "actionPerformed" section to see exactly what I'm trying to do and hopefully as well see what I'm missing as to why it is not working at the moment... Also see under the Refresh function where I commented out the for loops to add the pieces. I did this because it was resulting in an ArrayOutofBounds error so I just wrote each spot out manually where I wanted them to start.

I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
frame.setIconImage(Image image)
which does not work for me.
how do you get from launching some java code in eclipse to launching a java program from your desktop.Does one somehow wrap the code in C+ to make it a .exe? take for example Mine-Craft.Its build in Java however launches as a .exe.
