Which Layout Manager allows this
hi i have a JPanel with the size of 300w 300h, this JPanel is inside a horizontal split pane. I need to add a JTable inside the JPanel at coordinates x = 350 and y = 20; which means it is placed hidden inside the JPanel because the size of JPanel is smaller. how do i do this? it wont let me.
The idea is that when i move the split pane it will show the table. thanks very much
Thanks for the reply, i did that but nothing appeared
in my panel. Did i miss setting up anything.
Thanks again.I think that the width, height, x, and y of the component default to 0, which is why you can not see the component. To set them use:
component.setBounds(x, y, width, height);

Which layout manager can do this?
Heya folks.
I've been developing a piece of software and laid out the UI by hand (not using any NetBeans or whatever).
What i have issue with now is setting 3x JTextFields to 33% of the frame's width. Im using GridBagLayout with constraints and cannot achieve that effect.
Here is the example of what im trying to achieve (and yes its photoshoped, well....actually "MSpaint"ed :P )

As a side note. Not that I am doubting the power of the LMs you outlined. To read Karsten's* (JGoodies) posts on public forums indicates he has a far better grasp of easy & fluid layout management than is incorporated in many of the core layouts.

Being Nice to your Layout manager - Is this the right way?
Ive written a custom component that basically provides multi-line text wrapping and a few other nice things.
I had a bit of trouble when I came to implementing
getPreferredSize() getMinimumSize() This is because ideally, I'd like the component to use as much space horizontally as possible, whilst using only as much vertical space as necessary.
To do this, I used the parents width as the minimum horizontal size. This then allowed me to work out the height.
Question is - is that the right way to do it? Other than that, I just cant think of a way to get the width I need when the component is first added to its container.
Cheers for any input,
DaveIf you want it to use as much horizontal space as possible, that means you want its width to be equal to its container's width (perhaps minus a bit for borders or something). So in that case you would have to set its minimum width to that number, and that's exactly what you did. There could be other ways to do it, but yours seems perfectly fine to me.

Is there any simple layout manager?
One that just put things where I wanted them without changing their location?
I've set the x and y for each component, why changing it?
I've tried setting the layout manager to null but then it just doesn't display nothing...> But when I did that, nothing displayed even though
I've set the location and size of each component.
You can do it like this:import javax.swing.*;
public class HelloWorldSwing {
private static void createAndShowGUI() {
JFrame frame = new JFrame("null layout");
frame.setSize(150,150);
frame.setLayout(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel("Testing 1, 2...");
label.setBounds(30,20,100,25);
/* setBounds(30,20,100,25) =
+----------------------------------------
| ^
| | 20
| 30 v 100
|<--------> <----------------------->
| ^
| | 25
| v
|
frame.getContentPane().add(label);
frame.setVisible(true);
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}But it's better to use a layout manager. This is a good tutorial:

I have a 2T apple time capsule and router. I bought a Hauppauge Win TV extender which allows TV to be broadcasted on a PC. The program allows for the TV to be streamed on a Mac, Iphone, Ipad. I need to access the router set up options to open a port on the router to allow this program to stream the TV to the Mac and Iphone. I do not know how to access the apple time capsule router to change the settings to open a port on the router. help please.
Firstly you do not need to open ports to stream locally.. there is no port block in local LAN.. only WAN to LAN. So there is a good chance it is not needed at all..
Opening ports on the TC I strongly recommend a v5 airport utility.. you can download one for windows if you don't have a Mac.. iOS version of the utility I am not sure but it will not work to do complex things.
In the v5 utility go to the NAT area, and click on port mappings.
Sorry I don't have a screen shot at the moment of the actual mapping page.. but simply put the IP of the device you want opened and the port.
There are plenty of posts with this info if you google.
But as noted.. this is purely WAN to LAN.. nothing else. -
Have mac book pro, OS X Yosemite 10.10.1. I get this after start up: "Completer wants to make changes. Type your password to allow this" (which I have not entered. When I cancel, there is some unknown "installer" icon on my desktop. If I move it to the trash, this all just starts over on the next time it is restarted. Have screenshots, but for some reason I can not attach to this message right now. Heard this is malware...HELP!
There is no need to download anything to solve this problem.
If Safari crashes on launch and you don't have another web browser, you should be able to launch Safari by starting up in safe mode.
You may have installed the "Genieo" or "InstallMac" ad-injection malware. Follow the instructions on this Apple Support page to remove it.
Back up all data before making any changes.
Besides the files listed in the linked support article, you may also need to remove this file in the same way:
~/Library/LaunchAgents/com.genieo.completer.ltvbit.plist
If there are other items with a name that includes "Genieo" or "genieo" alongside any of those you find, remove them as well.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those.
After removing the malware, remember to reset your home page in all the web browsers affected, if it was changed.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, then you may have one of the other kinds of adware covered by the support article. Follow the rest of the instructions in the article.
Make sure you don't repeat the mistake that led you to install the malware. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked. -
How to make a scanned PDF file searchable? I bought an Adobe service which I thought allowed me to do this, but I do not see any instructions how to do it.
Hi,
When using Adobe ExportPDF online service, it will run OCR itself when converting any PDF to other file format.
It also depends upon the quality of the scanned document, so it might be possible that it does not make the file searchable.

Whis layout manager should I use for this type of gui? Any details about how to set it up would be aprreciated as well.
http://www.kommi.com/images/fetch-panel.jpgwhich layout for this?You are not restricted to a single Layout Manager. Mix and match to get the desired effect.
For example maybe start with a BorderLayout. Add one panel to the West and the other panel to the Center. The West panel might use a GridLayout. The Center panel might use a BorderLayout, then add the text area to the center and the progress bar to the south.

Customizable Ringtones... Which Models allow this?
I have a black flip phone... not sure what model, but it does not allow customizable ringtones... I will send sound files to the phone, but it is under "sounds" and there is no option to save it as a ringtone.
Before, I had a razr (or however you spell it) that DID allow customizable ringtones, I had a theme song to my favorite videogame as my ringtone, and it allowed me to send the file to the phone and save it as my ringtone.
Now... can anyone tell me why some models will allow this and some will not? Like there is some feature or program that will allow this detail on a phone? I have asked the staff at my local verizon stores, and online represenatives, but no one knows what makes the difference in what will allow a customizable ringtone.
I know I cant possibly be the only person who has had this problem, so Im hoping someone here can help, me please!archblade7777, I understand your concerns. Each phone is different because each are a different model and because of the different manufactures. Each phone model can have similar features although they have the same manufacture. The manufacturer can also remove and add different features to each phone series. What type of phone do you have. We can review the your manual and provide you with more detailed information about your particular phone. Please reply with your phone model and the community can assist you with further.

Placing components without layout manager not working
Hey there, I am working on a java game version of pong which I have begun to try and do using Java Swing. The problem I am currently having is reposition the components in the main window part of the game which is were the user can start a new game or close the program. I having tried using the absolute positioning by setting the layout manager to null but then everything goes blank. I can't figure out why this is not working. Here is the code so far...
import javax.swing.*;
import java.awt.*;
public class SwingPractice extends JFrame
private Container contents;
private JLabel titleLabel;
private JButton startGameButton;
public SwingPractice()
super("SwingPractice");
contents = getContentPane();
contents.setLayout(null);
this.getContentPane().setBackground(Color.BLUE);
startGameButton = new JButton("Start Game");
startGameButton.setFont(new Font("Visitor TT1 BRK", Font.PLAIN, 24));
startGameButton.setForeground(Color.cyan);
startGameButton.setBackground(Color.blue);
startGameButton.setBounds(350,350, 75, 75);
titleLabel = new JLabel("The Amazing Ping Pong Game!!");
titleLabel.setForeground(Color.cyan);
titleLabel.setBackground(Color.blue);
titleLabel.setOpaque(true);
titleLabel.setFont(new Font("Visitor TT1 BRK", Font.PLAIN, 24));
titleLabel.setBounds(0,350, 75, 75);
contents.add(startGameButton);
contents.add(titleLabel);
setSize(700,350);
setResizable(false);
setVisible(true);
/*private class SwingPracticeEvents implements ActionListener
public static void main(String [] args)
SwingPractice window = new SwingPractice();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Any other critiquing would be greatly appreciated. Thank you.

I was hoping that someone could shed some light on why one layout manage will allow an applet to be inserted in a class that extends JFrame but not another.
Here is the guts of the problem I have an class that extends applet to display a pie chart. I then have a seperate class that extends JFrame that display two input boxes and a button. When the user enters two fields and clicks draw the pie chart displays working with the two numbers. The JFrame class that works uses the border layout. I change the class to use gridbag, and now only the textboxes display. Can anyone help. Here is the code for the three classes.
This is the applet class....
* File: PieChart.java
* PieChart class is an Swing applet that use a pie chart
* to show the percentage. It is used by PieChartExample
* to show what percetange of a payment actually goes to
* pay interest. There is no error handling in the program.
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import javax.swing.*;
public class PieChart extends JApplet {
final static Color bg = Color.white;
final static Color fg = Color.black;
private double percent;
public void init() {
//Initialize drawing colors
setBackground(bg);
setForeground(fg);
percent = 1.0;
public void setPercentage(double pct) {
this.percent = pct;
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2.setPaint(fg);
drawAnnotation(g2);
drawArc(g2, percent);
public void drawAnnotation(Graphics2D g2) {
// draw a small green circle
g2.setPaint(Color.green);
g2.fill(new Ellipse2D.Double(200, 200, 10,10));
// draw a small red circle
g2.setPaint(Color.red);
g2.fill(new Ellipse2D.Double(270, 200, 10, 10));
g2.setPaint(Color.black);
g2.drawString("Interest", 210, 210); // write "Interest" by green circle
g2.drawString("Principal", 280, 210); // write "Principal" by red circle
public void drawArc(Graphics2D g2, double percent) {
// draw the interest portion
g2.setPaint(Color.green);
g2.fill(new Arc2D.Double(10,10,200,200, 0, percent * 360, Arc2D.PIE));
// draw the rest (principal portion)
g2.setPaint(Color.red);
g2.fill(new Arc2D.Double(10,10,200,200, percent * 360, (1-percent)*360, Arc2D.PIE));
This is the JFrame class using Boarderlayout that works.
* File: PieChartExample.java
* The program demonstrate a simple use of pie chart. It takes total
* payment and interest paid from user input and draws a pie chart
* to show the percentage of interert to total payment. There is no
* error handling whatsoever in the example program, so you can see
* that it can be broken easily.

This is the modified class to use GridBag that fails.

}Ok. It seems I may be wrong and that this may not be a concurrent call issue. I overode the components setBounds and setLocation methods and it appears that an external class is updating the position of these components while layoutContainer is attempting to position them. I can see that the correct positions are being set in the setBounds method, but this is happening after layoutContainer has called getLocation on the components. To be a little more specific, I am using a JLayeredPane to display some overlapping JLabels with images. I have implemented drag and drop on these labels so that dropping one on another swaps the images. The label positions and sizes are not being changed during the drop (I don't want them to move or resize just change images). However, for some reason I have yet to discover, two calls to set bounds are being made on the labels. The first call is relocating the label to the second labels position, the second call is relocating the label back to it's original position. If anyone has any insight on why the label position are changing when I am not explicitly repositioning them please reply. I will post another reply when I have corrected the problem or found a work around for it. I am awarding the dukes to tjacobs1 since he was the only responses I've had so far.

Layout Management in Table Control
Hi Dialog Programming Experts,
I have a new requirement - adding Layout Management options in Table Control. This is dialog/module programming, not ALV Report. Is there a function module for this?
Thanks so much in advance for your help.
Regards,
JoyreenHi
For filter use the following function modules,
l_rightx-id = l_index.
l_rightx-fieldname = 'DESCR'.
l_rightx-text = text-054.
APPEND l_rightx TO i_rightx.
l_index = l_index + 1.
CLEAR l_rightx.
l_rightx-id = l_index.
l_rightx-fieldname = 'DEL_CM'.
l_rightx-text = text-055.
APPEND l_rightx TO i_rightx.
CALL FUNCTION 'CEP_DOUBLE_ALV'
EXPORTING
i_title_left = text-034
i_title_right = text-035
i_popup_title = text-036
IMPORTING
e_cancelled = l_cancelled
TABLES
t_leftx = i_leftx[]
t_rightx = i_rightx[].
Firstly populate the right table with all fields which you want in the filtering condition. The left table will be populated once the use selects some fields and transfer it to the left portion of the dialog.
Then use the following FM like this.
DATA: i_group TYPE lvc_t_sgrp.
CALL FUNCTION 'LVC_FILTER_DIALOG'
EXPORTING
it_fieldcat = i_fldcat1
it_groups = i_group
TABLES
it_data = i_ziteminvoice[]
CHANGING
ct_filter_lvc = i_filter
EXCEPTIONS
no_change = 1
OTHERS = 2.
here filter table should have fields from left table above.
Once you get the filter data, populate range table for each fields and then delete your internal table using these range.
CASE l_filter-fieldname.
WHEN 'ITMNO'.
l_itmno-sign = l_filter-sign.
l_itmno-option = l_filter-option.
l_itmno-low = l_filter-low.
l_itmno-high = l_filter-high.
APPEND l_itmno TO li_itmno.
CLEAR l_itmno.
DELETE i_ziteminvoice WHERE NOT itmno IN li_itmno OR
NOT aedat IN li_aedat OR...
First check this if it works, else let me know.
Thanks
Sourav.
