Laying out buttons in a panel

I have a panel with 4 buttons. The panel is added to the main window using BorderLayout.SOUTH so that the buttons are at the bottom of the window. Now I want to align the buttons on the right side of the panel, like so:
| |
| ----- ----- ----- ----- |
| | b1| | b2| | b3| | b4| |
| ----- ----- ----- ----- |
| |
The obvious thing to do here is use
myPanel.setAlignmentX(Component.RIGHT_ALIGNMENT);
But it doesn't work. Any suggestions are greatly appreciated.
Jason

Any idea why the
panel.setAlignmentX(Component.RIGHT_ALIGNMENT)
wouldn't do the trick?Because the panel is using a BorderLayout. Any inherent behavior specified by the panel would be overshadowed by the behavior specified by the BorderLayout layout manager.
By the way you also asked a component alignment question here: http://forum.java.sun.com/thread.jsp?forum=57&thread=352465
If any of the replies answered your question then you should award the duke dollar.

How can I copy a button to a panel?

I am working on this project where I have 3 buttons that need to be dragged to a panel. I have created a new TransferHanndler that can support dropping to a panel. Now I have to figure out to actually copy an image of that button to the panel wherever the mouse position is, and be able to move it around in that panel and change its position.
Here is what I have so far:

Help! How can I lay out forms?

Hi:
I've tried everything and I just can't get Java to lay out a form for me.
I'm currently using TableLayout:
http://www.clearthought.info/software/TableLayout/
I expect the buttons to be in the bottom right hand corner of the form.
Only one shows up and it's apparantly over top the other one. They're at the top of the form.
What am I doing wrong?
public static void main(String[] args)
        btnOne = new JButton(" One ");
        btnOne.setPreferredSize(new Dimension(80, 25));
        btnTwo = new JButton(" Two ");
        btnTwo.setPreferredSize(new Dimension(80, 25));
        lbOne = new JLabel("Top Label");
        lbTwo= new JLabel("Second Label");
       double size[][] =
            {{TableLayout.FILL, 200},
             {0.05, TableLayout.FILL, 25}};
        pnExt = new JPanel(new TableLayout(size));
        pnExt.setPreferredSize(new Dimension(775, 575));
        double sizeLbl[][] =
            {{250},
             {0.05, TableLayout.FILL, 25}};
        pnLabel = new JPanel(new TableLayout(sizeLbl));
        pnLabel.add(lbOne, "0, 0, l, t");
        pnLabel.add(lbTwo, "0, 0, l, t");
         double sizeBtn[][] =
            {{150},
             {TableLayout.FILL, 25, 25}};
        pnButtons = new JPanel(new TableLayout(sizeBtn));
        pnButtons.setPreferredSize(new Dimension(125, 550));
        pnButtons.add(btnOne, "0, 1, r, b");
        pnButtons.add(btnTwo, "0, 2, r, b");
        pnExt.add(lbOne, "0, 0, l, t");
        pnExt.add(pnLabel, "0, 1, l, t");
        pnExt.add(pnButtons, "1, 0");
        fme = new JFrame("My Test");
        fme.setSize(800, 600);
        fme.getContentPane().add(pnExt, BorderLayout.WEST);
        fme.show();
    }

I've never used TableLayout, but here is some code for a common situation. Suppose you want components arranged like this:
label component (say text field or button)
label component
label component
import java.awt.*;
import javax.swing.*;
public class LayoutExample {
    public static void main(String[] args) {
        JPanel p = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.anchor = GridBagConstraints.NORTH;
        gbc.insets = new Insets(0,5,0,0);
        //row 0
        gbc.gridy = 0;
        gbc.gridx = 0;
        p.add(new JLabel("label 0", JLabel.RIGHT), gbc);
        gbc.gridx = 1;
        p.add(new JTextField("field row 0", 20), gbc);
        //row 1
        gbc.gridy = 1;
        gbc.gridx = 0;
        p.add(new JLabel("label 1", JLabel.RIGHT), gbc);
        gbc.gridx = 1;
        p.add(new JTextField("field row 1", 20), gbc);
        //row 2
        gbc.gridy = 2;
        gbc.gridx = 0;
        p.add(new JLabel("longer label 2", JLabel.RIGHT), gbc);
        gbc.gridx = 1;
        p.add(new JButton("row 2"), gbc);
        //row 3
        gbc.gridy = 3;
        gbc.weighty = 100;
        gbc.gridx = 0;
        p.add(new JLabel("label 3", JLabel.RIGHT), gbc);
        gbc.gridx = 1;
        p.add(new JButton("row 3"), gbc);
        display("LayoutExample", p);
    static void display(String title, Component c) {
        JFrame f = new JFrame(title);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(c);
        f.pack();
        f.setLocationRelativeTo(null);
        f.show();
}Resize the frame. the components remain centred horizontally but anchored to the north (that's the effect of weighty).
Of course, your mileage may vary, but don't give up on GridBagLayout. It reminds me of that 60's song, "If you want to be happy for the rest of your life (get yourself and ugly wife)"...

Adding a column in the Universe level without losing the Report Lay out

Hi all,
I have one universe with three universes built on it. Now, I want to add a column to one of the tables in the universe. For that, I selected the table and gave 'Refresh the structure'. The column got added in the workspace of the universe. When I drag and drop the table to the class & objects panel, it got added to the class/table in the panel. I saved and exported the universe.
When I do like above, and open the report in the BO XI R3.1 webi front end, the report throws the following error:
'Universe contains unresolved objects' and the report lay out is lost. All the three reports built on this universe is throwing the same error.
Please let me know if there is any other way to retain the report lay out and add the column in the universe level.
Thanks in advance

Arun

Buttons showing in panel help

HI,
This was my final year project and im trying to tidy it up a bit so I can add it to my protfolio but im having a big problem with the following:
I have several panels all in a container, one is a button panel and one is a screen which shows an algorithm running. When you press or hover over a button in the button panel, it is displayed in the top left corner of the screen panel.
the applet is here: http://homepage.ntlworld.com/k.wood143/FinalCopy/algo.html
to get to the source just take off algo.html
the classes you want are algoApp.java, and /runjava/GrahamScan.java
any help or questions will be greatly appreciated, thanks in advance

this edited version of your code does not show the buttons in the panel. The problem was your incorrect implementation of JPanels. You should never override paint(..) but paintComponent(..) instead. your implementation would have been ok for AWT but not Swing. get rid of all of your update and paint functions. put your 'update' code in paintComponent() save the call to repaint(). The DefaultPoints Panel is unnecessary. here is a revision of GrahamScan:

Making lay-outs in Dreamweaver

Hello;I have been studying 2 Dreamweaver learning books(and a lot of “background books“(php) the past 3 years.In one of them the author explained the different ways of using lay-outs in DW.(the “ready to go” css lay-outs,tables,etc.) However:I want to make my own designs,instead of using pre-designed lay-outs.(and tables)Therefore the possiblity of using AP divs seemed to be the best way. A disadvantage of the AP divs is,of course,that the divs are absolutely positioned,so that on a small screen the content is moving to the right. Because of the fact that making designs using AP divs,just like using a pencel or brush like a real painter does,makes designing a lot of fun(instead of playing in the plain code) I kept on using the AP divs,but instead of “position:absolute” I have changed this into “position relative”. I have also used a container in which I put all the other divs,just for keeping it all centered. At first site,it looked all fine,but when inserting other stuff,like plain tekst,extra code or images,everything went nuts,a bit like when using a table:all the divs weren’t positioned nicely anymore and I had to re-place everything again. The changes kept going on and,especially in the design-mode,it’s all messed up. So my question is: What lay-out method do you all,as experienced webdesigners,prefer to use,according to modern standards??(and still make designing a fun thing to do,without programming in the code) Of course with the use of Dreamweaver and all its toolbars,buttons and features. I really hope you have the answer for me!!! Many thanks for the help you are giving me!! Greetings igor

Hi Again
I tend to use whatever css based layout type I think is best suited for the design, (never tables for layout and absolute positioned items with caution, see my answer to your previous thread regarding % values) this may even include using 'trial' feature such as html 5 and css3 with jQuery or whatever.
The thing is with layouts, is to decide how you wish your page to look and function, then work out how-to-do it, that for me is what keeps it interesting. As an example I have even experimented with using a flash swf as a resizeable background image with animation, (works, but the browser must be resized by 1px to force the swf to resize on initial load of page).

Help laying out a simple page

I need a page where I have a tree on the left and a data table next to it on the right. I'd like the tree and the data table to have the same vertical starting point so that the tree looks something like the first column of the data table:
+------------------------------------------------------------------+
| Tree Header |                Table header                       |
-------------------------------------------------------------------+
| - Root      | Col Header | Col Header | Co Header | Col Head |
|   |          |---------------------------------------------------|
|   - Node     | value     |   value      | value     | value   |
|   |          | value     |   value      | value     | value   |
|   | - Leaf   | value     |   value      | value     | value   |
|   |          | value     |   value      | value     | value   |
|   + Node     | value     |   value      | value     | value   |
...I'm trying to lay this out with a grid panel with two columns and then a tree control in the first colum and a data table control in the second column, but I am having a heck of a time to get this to layout correctly. I'd like the tree area to consume about 25% of the space and the data table to consume about 75% of the space and I want them to pack towards north west. I could easily do this with Swing but I'm having a difficulty here.
Any help will be greatly appreciated.

Dave Saunders,
I am eternally grateful to you. You have no idea what you've saved me from and you've given me time to salvage whatever is left of my weekend.
You are a saint of a man. Thank you :)

How do I sign out of my account after logging in? There is no sign out button when signing into my apple account using safari

Every time I sign into my apple ID account online I cannot log out by clicking a "sign out" button.
This is quite strange. Closing the browser window doesn't automatically log me out either.
I know with itunes there is a sign out or log out button but not with signing in your account online.
I had to change some personal information which is why I noticed it.

I'm on a PC. Maybe that makes a difference. And I went directly to apple.com; I did not launch the store from Itunes -- so perhaps that's the difference.
Whatever it is I am never presented with a command bar that looks anything like yours.
The following image is from when I am actually accessing my account data:
No log-in; no screenname; no log-out -- And yet I am in a secure domain.

How can I use the button in one panel to control the other panel's appearing and disappearing?

How can I use the button in one panel to control the other panel's
appearing and disappearing? What I want is when I push the button on
one button . another panel appears to display something and when I
push it again, that the second panel disappears.

You want to use a combination of three features, a button on the panel,
code to notice value changes using either polling in a state machine of
some sort or an event structure, and a VI Server property node to set
the Visible property of the VI being opened and closed.
The button exists on the controlling panel. The code to notice value
changes is probably on the controlling panel's diagram, and this diagram
sets the Visible property node of a VI class property node to FALSE or
TRUE to show or
hide the panel. To get the VI reference to wire to the
property node, you probably want to use the Open VI Reference node with
the VI name.

Why does ical on icloud have a different lay out than on my mac

Why does iCal on my MacBook Pro have a different lay out than on iCloud? I like the iCloud layout better, the only missing niceties is the year calendar. How do I get both iCals to look the same? The ideal iCal? The one from iCloud WITH the year calendar.

After installing the update to version 9 of Firefox, I can access some items on my toolbar. The log out button on my GMail can no longer be accessed, what's wrong.

None of the toolbar items, on the log out row, on my gmail account are active anymore. I also had this problem with my discover account, I couldn't use the log out button there either. When I called Discover, they told me their site was not yet updated for for version 9 of Firefox.

On iPhoto, I can no longer access the 'Classic' option which would lay out my photos on the page. It will send them as attachments only. I need the page layout for my work. Any thoughts as to why this has changed?

On iPhoto, I can no longer access the 'Classic' option which would lay out my photos on the page. It will send them as attachments only. I need the page layout for my work. Any thoughts as to why this has changed? It used to fully lay out the photos so I could add notes and detailed information before I sent them. I am thinking it is something simple that I have just missed...

The "Photos" view has been replaced by the Media Browser.
Most applications will show you the Photos icon in the Sidebar, when you need to select photos in a file chooser dialoge. Mail, Safari, the iWork apps. See Terence Devlin's User Tip: How to Access Files in iPhoto
For example, in the File > Open dialogue in Preview I am seeing this in the sidebar.

Hi experts,
       Pls anybody have an answer to my question, i'll be very thankfull to u,
                 I wanted to display the Tax Break ups in Invoice say,
ECess            25
Vat                 56
Excise duty    32
I've tried a lot with many of the SAP Forum thread but the results is not satisfactory..am using SAP Business One 2007 b
pls anybody who can guide me with step by step PLD creation for this problem.
I done the below steps in PLD
In Repetitive area 1
Field_1: Table-> OSTA
              Column-> Type
Field_2 : Table-> OSTA
              Column -> Code
Field_3: Table-> OSTA
              Column-> Rate
Field_4: Table-> OSTA
              Column-> Name
Field_5: Table-> A/R Invoice Tax amount per document
                Column-> Tax amount
Field_6 : Table-> A/R Invoice Tax amount per document
                Column-> Base amount
Field_7 : Formula -> Field_6 * Field_8
Field_8 :   Formula-> Field_1==1
      NOW I SORTED REPETITVE AREA 1 WITH 'SALES TAX AUTHORITIES;cODE' AND TICKED THE CHECK BOX 'SUMMARY'
    AND MADE THIS REPETITIVE AREA INVISIBLE.
IN Repetive area footer
F_01 :    Formula->   Field_4
F_02 :    Formula->   Concat(Round(F_rate,0), '%')
F_03 :    Formula->   Round(ColSum("F_tax_amount"),2)
I grouped the Repetitive area footer as Group 1
                            here i get the result but the Tax Rows are repeating and Tax amount varies for VAT for each rows
pls help me guys...
               Thanks in advance,
               Dinesh
