I'm trying to get my components to align in the proper position but I'm having no luck what so ever. I have my code and I've attached an image of my window builder. It's just one of those small aggravating things thats probably right under my Noes.

I am trying to send a JPanel object to the server. While doing so I get the error -
java.io.NotSerializableException: javax.swing.filechooser.WindowsFileSystemView at java.io.ObjectOutputStream.writeObject0(Unknown Source) at java.io.ObjectOutputStream.defaultWriteFields(Unknown Source) at java.io.ObjectOutputStream.writeSerialData(Unknown Source) at java.io.ObjectOutputStream.writeOrdinaryObject(Unknown Source)
I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){ while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){ rotateBottomClockwise(1); System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is: alignment is: W-G and tops: R-R NOW ITS ALIGNED even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out ** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube ** ** ** R6 W5 O4 ** ** ** ** ** ** R3 W2 O1 ** ** ** B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube B2 G5 R8 W4 R5 Y6 O2 B5 G8 O7 W8 R9 B7 B8 B9 R1 R4 R7 ** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube ** ** ** Y2 Y5 Y8 ** ** ** ** ** ** B1 G6 W7 ** ** ** ** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube ** ** ** R2 O5 G2 ** ** ** ** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2
I decide to make a new GUI just for fun and practise and i want to learn more about Layouts.. right know i am try to understand some staff about GridBagLayout.
I want to make a GUI with this Layout :
So..first i am a frame with borderlayout then i put a JMenuBar and bla bla bla and i create panel with GridLayout which i put on myFrame.add(panel1,BorderLayout.WEST) and also i make an another JPanel which i put of the Center of main Frame (myFrame.add(panel2,BorderLayout.Center))
when i run the program i get this GUI :
Now the problem is that i can't put the JButton on the top of the gridLayout just to look like the first picture.. i Read about anchor and i try to
gbc.anchor = GridBagConstraints.NORTH; but without results.. still the components are on the middle of the JPanel..
I know my problem is my lack of understanding of OOP but I have searched for a solution and can't even seem to get close.This is a very simplified version of what I will need to do. I have a button and six textboxes. When the button is pressed I want to take the text from textbox6 and place it in textbox1, textbox2, textbox3, textbox4, and textbox5.
I need sometthing better then this brut force method.Java Code:
package textboxes; public class TextBoxesGUI extends javax.swing.JFrame { public String NewText; public TextBoxesGUI() { initComponents();
I want to make a simple Table Tennis game. I have 2 drawing classes. 1st should draw oval and 2nd rectangle. But second class, which should draw rectangle doesn't work and if i use it together with oval class, then oval doesn't appear too.
Java Code:
public static void main(String[] args) throws InterruptedException { Intro i = new Intro(); Pall pall = new Pall(); Laud laud = new Laud(); i.frameID().add(pall); // this adds oval i.frameID().add(laud); // this adds rectangle i.frameID().pack(); i.frameID().setSize(400, 400);

As I couldn't find a way to do the printing of multiple items on one page, I decided to test out my idea. I found that I could have a table in a JTextPane.
However, whenever I got to print, my table will vanish. It doesn't even need to go to the printer. Just bringing up the print dialog will make it vanish like tax money in D.C.
(Also, I'm not really that familiar with JTextPane and it seems harder than JTextArea. Which part is controlling the font of my regular text by the way? I think it might be tableParagraph but it could also be the base font. I can try and fiddle with both and waste paper but where the font is being set.
Setting the font with setFont() will vanish my table. )
Somehow, I'm thinking that the solution might be JTextPane.setContentType() or setEditorKit() or both. (I"m not that familiar with either, but I fear that it's only being set to handle text, hence any graphics are being lost.)
Here is my code:
import java.awt.*; import javax.swing.*; import javax.swing.table.*; import javax.swing.text.*; public class AddingTables { JTextPane textPane; private Object[][] rows; private Object[] colNames;
I have a JPanel with vertical BoxLayout. It contains four components. I set the JPanel to LEFT_ALIGNMENT, which has no effect on its components. I set the first component to LEFT_ALIGNMENT, which has no effect. Only after I have set all four components to LEFT_ALIGNMENT do any of them align properly.
This suggests that it is impossible to have varying alignments in a container. They must all be the same alignment.
I accept that this is just the way things are: "Java works in mysterious ways." And I'm sure that it is possible to work around this limitation by stacking boxes that themselves have different internal alignments.
But I still wonder what in the world was going on in the minds of the Java developers. Is there a rational reason for this oddity?
This raises my most serious criticism of Swing: the hidden gotcha. Swing is a tangled mess of cross-connecting requirements that are impossible to divine by simple inspection of the documentation. If you want to use, say, a JRadioButton, it's not enough to study the documentation on JRadioButtons; you must also consult lots of documents for which there is no obvious connection to JRadioButton other than it being part of Swing.
dynamically create tabs by pressing a button, each tab has Primefaces input texts in which i'll be adding stuff and with a Submit button i'm submitting the form.
My issue now is this; although I can create more buttons through my managed bean, I cannot set the ValueExpression to the InputTexts. When I do:
inputName.setValueExpression("value", createValueExpression("#{cdiBean.name}",String.class)); it doesn't work.
The createValueExpression is a static method in my managed bean and it returns a ValueExpression. I'm most certain I found it online, not sure where though, it's been over a month since the last time I worked with this topic.
Anyway, is my whole "methodology" correct? Should I do anything differently?
I have swing UI designed and I want the components to resize when the frame is manually resized. The design is as shown in the fig Project UI.jpg
The panel 4 and panel 5 will change their contents according to the list item clicked. Panel 4 just has text area but panel 5 a panel with numerous components as label, combo box, text field,check box will be present.Now if the frame resizes, I won't all the components to resize according to the frame size.
If we have request which hit the server, before it reaches servlet or the response going to send the browsers, through how many components it pass through (or the process flow).
Let me explain by simplifying the GUI to a simple frame in which I have a JCheckbox and a JPanel mypanel.mypanel has a Textfield tf,JComboBox cmb as it's components.So now if I deselect the JCheckbox, all the components in the mypanel should be disabled. I used a code like:
but the components inside the panels are not disabled. In my actual program I have a large number of different kinds of components in mypanel.So disabling/enabling each of them on each actionPerformed of the mycheckbox will be laborious. Isn't there any way by which I can disable/enable the mypanel to disable/enable all the components in it?
I keep hearing these two term when it comes to painting in Swing, however, I'm not sure which is which. To my understanding is that the child components are the ones that already exist on screen (could be a JButton, JFrame, or custom painting) . and the parent components are the one to be added/drawn next. (hence, if we override the paintChildren() method when painting, the components that were already on the screen don't appear any more).
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
public class Frame extends JFrame{ private final static int WIDTH=400, HEIGHT=400; public Frame(){ super(); super.setSize(WIDTH,HEIGHT); super.setVisible(true);
[Code] ....
In my main class I am just creating the frame and the panel then adding the panel to the frame.
I noticed that when building a UI programmatically in several steps the width/height of the Pane I use for layout is -1/-1. I read that this is the case until the actual rendering happens. Is there a way to force that earlier? Suppose I wanted to size other UI components (which are not visible initially) according to the size of another pane. How do I do that? Binding the properties does not do the job in the case that those components are not necessarily visible at the same time. Is there a trick to achieve that?
My panel named panelIncomeInfo are not showing the components that I have added.
public class PayrollGUI { private JPanel panelIncomeInfo = new JPanel (); private JPanel panel = new JPanel (); private JPanel panelPayCheckInfo = new JPanel (); private JButton close = new JButton ("Close");
