Set Components To GridbagLayout
Jan 1, 2014
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..
Here is my Code () :
Java Code:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
[Code] .....

How do you use GridBagLayout and CardLayout together?
I'm trying to add these buttons to a panel, but it breaks the GridBagLayout, here's what is in the doc;
Java Code:
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
[Code] .....
I'm trying to do:
Java Code:
JPanel m = new JPanel();
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
m.add(button, c);
[Code] .....
However it reverts as though it's using flowlayout. What is it I'm missing?

I'm trying to make a simple window that displays 5 text fields on x number of rows, depending on what I set x to. Attempting to do this with GridBag Layout but I can't seem to get a new row started. The closest I can get is to repeat the same fields on the same row. I'm trying to modify the row by putting the code in a loop and setting gridy = i, that way each iteration should place the code lower than the first. I'm new with GridBagLayout so I'm probably missing something simple. The constructor with the loop is below. I've commented out code that doesn't seem to work but left the gridx and gridy.
public PAMCalculator()
{
setTitle("PAM Calculator");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(WIDTH, HEIGHT);
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints gridConstraints = new GridBagConstraints();
setLayout(gridbag);
[code]....

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();
[code]....

Really need some simple and complete example on how to extends components (graphically and functionally) for primefaces 5.
For example I can't figure how to add custom attributes to existing component or define default values for existing attributes.
Is there any tutorial or a basic common way to achieve this goal or each component have to be extended in its way?

In some examples I see jsf components inside the tag view, other times dont.
- Is it important to put all jsf components inside "the view" tag?
- What would be the difference not putting them inside this tag?

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;
[Code] ....

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.

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:
[code]mycheckbox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if(mycheckbox.isSelected())
mypanel.setEnabled(true); else
mypanel.setEnabled(false); } });[code]
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).

Just some sample code:
Java Code:
mainPanel.add(background, new Integer(10));
cards.add(king[0] = new Card(200, 200, TILE_SIZE, TILE_SIZE, 0, 0)); mh_sh_highlight_all('java');
Then, when a card is created, it calls:
Java Code: Main.mainPanel.add(this, new Integer(1)); mh_sh_highlight_all('java');
Yet for some reason, the background is always painted OVER the card UNLESS I set the background to -1.

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?
