Layout problem in Swing.
Hi,
I have made an application in Swing containing Grouplayout on the panel.
On that panel I keep on dragging and dropping Swing Components like push button, textboxes etc and then save it using XMLEncoder i.e. I save the complete panel.
After saving, when I recall them using XMLDecoder, the layout is completely different.
I mean when I drag and drop the components to make a login screen and save them and when I open the same file they all appear in different layout.
Can anybody help me solve this issue.
Thanks and Regards,
Hi
If you have a layout that requires drag and drop support then you can't use a layout manager. You need to use a "null" layout so you can randomly position components.

I have an Layout problem. My Applications consists of a label and a panel in which some more labels are present.
The panel should contain the scrollbar in order to view all the label that excced the size of the panel.This label and a panel should be adjacent to each other.
My problem is, I am not getting the scroll bar to the panel when I am adding the label that excced the size of the panel, when I am adding the label adjacent to this label.Did you use JScrollPanel? If not, use it.

this my code for grid bag layout but when i run this code it is showing only empty panel..no components..
of course iam not posting entire code of tis class..because it is lenghty..
regards,
samWell, you set JPanel ja's layout to GridBagLayout, but it appears your adding the components to the parent, eg. add(j) should be ja.add(j) if you want it on JPanel ja. This is true for all your component adds.
By the you can combine the setConstraints( ) and add calls: ja.add(j, bgc);
Hope that helps.

Can someone please help me with a layout problem.
As far as I can tell the page looks as it should in Netscape,
Firefox, etc., but IE6 and 7 refuse to work correctly.
The page I am working on is:
http://www.vmtampademo.com/localangler/testpage.html
Most of the picture caption and headline of the middle column
is behind the picture. I attempted to force the info with a
seperating div which seems to work sometimes. I doubt that this is
the correct solution. What am I doing wrong?
Thank you for the help!It looks fine in Firefox 2.0.0.1, Opera 9.10, and IE 7.

Layout problem in PDF conversion
Hi all,
i am downloading spool data using the function module CONVERT_ABAPSPOOLJOB_2_PDF. But i am facing layout problem. e.g. RFBILA00(financial statement generation program) has written balancesheet data to the spool. This spool data has some 6 columns. but CONVERT_ABAPSPOOLJOB_2_PDF is writing only first 3 columns to the generated PDF file. i used 'GET_PRINT_PARAMETERS' function module also with values like layout as 'X_65_132' and 'X_90_120'. but no success. if anybody knows the answer, please let me know.

Layout problem - multiple repeating frames
Hi, I have a layout problem, pls help!
Short report description:
- Repeating Frame1 - gives 1 record, contains all other frames, variable vertical elasticity
- - Frame2 - contains all frames beneath - variable vertical elasticity
- - - Frame3 - variable vertical elasticity
- - - - some boilerplates
- - - - Repeating Frame 2 - various number of records, fixed vertical elasticity, height 100
- - - - Repeating Frame 3 - various number of records, fixed vertical elasticity, height 30
- - - - .. other repeating frames ..
When reaching the bottom of a page, and there is not enough room to print a record for Repeating frame 2, a record from Repeating frame 3 is printed in the bottom.
Next page starts with the remaining records from Repeating frame 2.. and then the remaining records from Repeating frame 3.
For example:
Page 1:
Rep frame 2 - Record 1
Rep frame 2 - Record 2
Rep frame 2 - Record 3
Rep frame 3 - Record 1 -- not enough space to print Record 4, so this record is printed
Page 2:
Rep frame 2 - Record 4
Rep frame 2 - Record 5
Rep frame 3 - Record 2
How can i ensure that all records from Rep frame 2 is printed before records from Rep frame 3?Hi, thanks for helping me out!
I tried to use anchors, but they had no effect when connecting top of 3 to bottom of 2, got the same layout.
I then tried to create frames with vertical elasticity expand around both rep frame 2 and rep frame 3, and it seems to do the job.
- Repeating Frame1 - gives 1 record, contains all other frames, variable vertical elasticity
- - Frame2 - contains all frames beneath - variable vertical elasticity
- - - Frame3 - variable vertical elasticity
- - - - some boilerplates
- - - - Frame 4 - vertical elasticity expand
- - - - - - Repeating Frame 2 - various number of records, fixed vertical elasticity, height 100
- - - - Frame 5 - vertical elasticity expand
- - - - - - Repeating Frame 3 - various number of records, fixed vertical elasticity, height 30
and so on..
Thanks again -
[solved] layout problem in amarok 2.02
Hi,
Here, I have a bad layout problem with amarok 2.02. Amarok does not fit on my screen which is 1400 pixels large! I cannot reduce the part where the collection is shown. So that it is really unpractical to use.
I uploaded a snapshot to illustrate the problem (it is the full screen!):
emmanuelfavrenicolin.free.fr/Public/Sna … ok202.jpeg
Someone have the same problem ?
I tried to install svn version but I stopped after 3 hours of compilation, it is quite a big application.
Last edited by manouchk (2009-05-23 06:28:43)Well, I tried amarok2-devel 2.0.90-1 but the problem of graphic layout remains similar, no improvement. Is it normall? Maybe amarok is only available for computer with screen >= 1600x1200 or is there an hidden configuration file where I could tweek this?

Urgent: Layout problem in "light inner page"
Hi Experts,
I am facing a problem in portal content area on external facing portal. I see a vertical scroll bar which restricts application from being displayed on entire screen.
I am getting this problem after a patching of EP 7.0, before patching every thing was running fine.
To me it looks like a layout problem in "light inner page", When I use "Light - 1: column (Full width)" layout I get a vertical scroll bar on portal. When I use default layout then this vertical scroll bar disappears but I see an empty navigation bar on left side which is not required.
Can some one advise a solution for this.

Hi - stuck on what I think should be a fairly basic layout problem:
I have 2 divs, equal widths but varying heights, one floated to the left and one to the right so that they appear next to eachother on the page. The one on the left contains varying amounts of text, the one on the right contains a flash player so never varies.
Where the text for the left div is long, I want it to start off next to the player, but then flow beneath it rather than continuing downwards at the same width as the div. If I remove the width of the left div, so that it reverts to the container width, the player div positions itself below it, so I can't work out how to get the effect.
Can anyone help?Hi,
hope I understood in the right way: I used (translated from German DW) "modify table" and so I got one more row and two columns in your Main_Content. In one of the new columns I copied the image and beneath I took the text (you now can replace with image and text of your choice), like this:
If that's not a help for your question, please ask me again.
What concerns the width of the pictures, I would format them with PS or a similar program in the same wide.

Design/Layout Problem in OOTB SP "Docs I'm following" page
Hello
The "Docs I'm following" My Sites page in SP 2013 has the following layout problem:
Long document titles overlap with other elements (see also screenshot).
Note: This is default SP, i.e. we have not deployed any custom branding.
I guess this is a problem which can easily be corrected even without having to wait for a SP update. Since I'm not very good with design changes I would be grateful if you could provide
us with a quick fix, e.g. an updated css file.
Thanks a lot.
Best regards
JohnHi ,
For your issue, you can add the following code into your MySite MasterPage:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".ms-contentFollowing-itemTitle a").each(function(i){
$(this).text(shorten($(this).text(),32));
function shorten(text,maxLength) {
var ret = text;
if (ret.length > maxLength) {
ret = ret.substr(0,maxLength-3) + "...";
return ret;
</script>

Hullo - I've written a little app that, because of the nature of what it does, prettymuch requires the use of null layout. It works well enough, but there are a few points where it does strange things that I don't understand. I haven't been able to find any good docs anywhere for how exactly layout/rendering works. The Swing tutorial, for example, almost completely ignores the topic.
Basically, I set the layout to null, add my components, use setBounds...but then nothing happens. In order for anything to be visible, I have to call pack() before I call show(). What is pack? What does it do? How can Sun's null layout examples work even though most of them don't use it?
Second, if I create JFrame of a certain size, and add a component that goes off the bottom of the JFrame (on purpose), then expand the size of the JFrame to reveal the bottom part of that component, it doesn't paint - there's just a grey area. No amount of repaint() pack() or anything will cause it to show. The only way I've found to do it is to make the JFrame larger to begin with, add the component so that it's visible, then resize to the smaller size, which is kind of ugly and clunky.
I basically do not understand why Swing is doing the things it does; why it paints sometimes and not other times, where it paints, when it paints, where it shows objects, how it packs them, etc. I would be very grateful if someone could englighten me!Hullo - I've written a little app that, because of the

Pack basically organizes the components so they take up the least amount of room, and then it shrinks the frame to as small as it will go without hiding any components. It think if you call revalidate() instead of repaint(), should solve your problem.
The other thing to do, is (hehe) make your own components -
Help needed with a layout problem
I'm trying to build a JTabbedPane where each tab has a grid of buttons. The number of buttons is variable, and I'd like the buttons to flow sort of like with FlowLayout, with four columns. I need all the buttons to be the same size, even across tabs. I tried GridLayout, which doesn't work when I have too few buttons to fill a row. It fails in different ways, depending on how I set things up. If I try to set the layout to GridLayout(0, 4) (four columns), then if one tab has one row and another has two, the buttons on the one-row tab expand vertically to the height of the two-row tab. If I try GridLayout(2,4), then if a tab has only one button, it expands horizontally to the maximum width of any of the tabs. (It also has the further problem that if the maximum number of buttons on any tab is 6, they are placed in a 2x3 array; I'm trying to get them to be 4 buttons on the first row and 2 on the second.)
I'm hoping there's a standard layout manager that can do the job, but I'm not too familiar with the Swing manager classes. Can I get what I want without writing my own layout manager?
Thanks,
Ted Hopp
[email protected]I didn't think it was specifically a Swing question.Well, its either Swing or AWT, people who develop GUIs are the ones who are going to have experience using layout managers.
but if someone can point the way to how to do this with GridBagLayout, nested containersSince you finished reading the tutorial, what have you tried? You've explained your problems using a single layout manager, so what problems are you having using nested layout managers?
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.

Need suggestion regarding Layout Manager using Swing in Java
I have developed a swing application where i am having problem with selecting the right layout manager.
I am attaching the file where it contains the method for addingComponents to the Content Pane. But, the code that i have written
contains lot of spaces between first panel and second panel and so forth.
Please suggest.
<<Code>>
public void addComponentsToPane(Container contentPane) {
this.contentPane = contentPane;
// File Panel
JPanel jfile1panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
JPanel jfile2panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
JPanel jfile3panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
JLabel jfile1 = new JLabel("Select File:");
jtfile1 = new JTextField(50);
jbfile1 = new JButton("Button1");
jfile1panel.add(jfile1);
jfile1panel.add(jtfile1);
jfile1panel.add(jbfile1);
jbfile1.addActionListener(this);
JLabel jfile2 = new JLabel("Select File:");
jtfile2 = new JTextField(50);
jbfile2 = new JButton("Button2");
jfile2panel.add(jfile2);
jfile2panel.add(jtfile2);
jfile2panel.add(jbfile2);
jbfile2.addActionListener(this);
JLabel jfile3 = new JLabel("Select File:");
jtfile3 = new JTextField(50);
jbfile3 = new JButton("Button3");
jfile3panel.add(jfile3);
jfile3panel.add(jtfile3);
jfile3panel.add(jbfile3);
jbfile3.addActionListener(this);
//Button Panel
JPanel jbuttonpanel = new JPanel();
jbuttonpanel.setLayout(new FlowLayout(FlowLayout.CENTER));
JButton jbcmd1 = new JButton("Submit");
JButton jbcmd2 = new JButton("Cancel");
jbuttonpanel.add(jbcmd1);
jbuttonpanel.add(jbcmd2);
jbcmd1.addActionListener(this);
jbcmd2.addActionListener(this);
//Content Pane
contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.Y_AXIS));
contentPane.add(jfile1panel);
contentPane.add(jfile2panel);
contentPane.add(jfile3panel);
contentPane.add(jbuttonpanel);
}But, the code that i have written contains lot of spaces between first panel and second panel and so forth.use pack(), see if it makes a difference
as you're using FlowLayout, make the frame not resizable -
Hello,
I am having difficulty with my box layouts in my form applet.
I have a JFrame with two panels. The left panel will allow the user to enter some parameters via text boxes, drop down menus, etc for a shape, which will appear on the right panel.
To arrange the form entry boxes on the left panel, I implemented a box layout. Here is where my trouble lies. I am not sure if I am using them correctly.
In the left panel, I added a box objectentitled entrySideBox, which has a createVerticalBox() orientation. I further added 7 boxes to this box layout, which had a createHorizontalBox() orientation. I have the form elements within the array of horizontal boxes. In summary, I hoped to create a box layout column with 7 horizontal rows to house the form entry elements.
Can I do this with the Box Layout? My form elements do not appear to be appearing as expected!
I have my code below. What is wrong?
