A small layout problem...

Hi,
I have a JPanel with a grid layout of 12 rows and 1 column. And it holds 12 buttons like so:
button1
button2
button3
button12
The problem is I would like a small bit of space between the buttons. Not closely packed as shown. any ideas? all help appreciated

try:
JPanel myPanel=new JPanel()
myPanel.setLayout(new GridLayout(12,1,5,10));where you'll a horizontal spacing of 5 pixels and a vertical spacing of 10 pixels.
;o)

Layout problem with JTabbedPane

Hi,
I'm creating a JDialog with a JOptionPane in it which has a JTabbedPane as its ContentPane
Supposed to look like the pic below. I've put the JOptionPane into a JScrollPane in case the user makes the Dialog too small.
Problem is that the JTabbedPane stretches to a very large height (way bigger than the dialog height).
Using setPreferredSIze(..) on the JTabbedPane doesn't help either. If the dialog is made bigger, then the TAbbedPane doesn't stretch, if it is made smaller, the TabbedPane shrinks to the minimum necessary size.
Any ideas, tips on getting this layout would be appreciated.

CSS Layout Problem?

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

Layout Problem in swings

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.

[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.

Div layout problem

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.

Small SQL problem

Hello,
I have a small SQL problem...
I am designing an online bank using servlets for a university project and it allows customers to view their statements. They select which of their account numbers they want to view the statement for and the start and end date of the statement.
The problem lies with the dates. Here is the SQL:
SELECT date, details, amount, balance
FROM HISTORY
WHERE bankaccnumber=13494925 And date>=1/1/01 And date<=31/1/01;
All of the books I have looked at show dates in '1/1/01' format but whenever I try it this way I get a 'Data type mismatch in criteria expression' error (the 'date' field in the Database IS a Date type).
Although, whenever I run the query in Access and prompt the user to enter the start and end date, it works fine.
I have spoken to a few people and no-one seems to know why it is not working.
Any ideas???
Thanks

If your database is MS Access and you don't expect to switch to something else, then write this:
SELECT date, details, amount, balance
FROM HISTORY
WHERE bankaccnumber=13494925 And [date]>=#1/1/01# And [date]<=#1/31/01#
Note that you MUST format your dates as MM/DD/YY and not as DD/MM/YY, that's an Access rule, and that you will probably have to "quote" your column name "date", which I think is a reserved word in SQL and hence a bad choice for column name.
Personally I always use PreparedStatements. That way my SQL would look like this:
SELECT date, details, amount, balance
FROM HISTORY
WHERE bankaccnumber=13494925 And date>=? And date<=?
and I would use the setDate() method to fill in the parameters. Since this method uses a Date as a parameter, I don't need to fight with date formats, the JDBC driver handles that for me.

Can Lincat find big endian and small endian problem?

Hi, I want to migrate a project from linux to solaris. And I read that lincat can save a lot of time in migration. But when I tried with lincat. I found that what is found is mainly the difference between linux API and solaris API. I use the following
codes:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
int flagVal = 0x01020304;
char cptr = (char )&flagVal;
printf("Val is %d\n", *cptr);
my lincat does not find the big endian and small endian problem. I also wonder whether lincat can find the misaligned problem and "32 bits and 64 bits" problem. Could you please tell me? I didn't find the answer from lincat manual.
Edited by: baiwd on May 6, 2008 6:03 PM

Hi Ankit,
You may use "Cross Platform Transportable Tablespaces" method if the endian format is different between source and target platforms. Please have a look at Oracle's "Platform Migration Using Transportable Tablespaces" document for more information: http://www.oracle.com/au/products/database/maa-wp-11g-platformmigrationtts-129269.pdf
Please note that "Transportable Database" is a different feature and can only be used to migrate a new database platform that has the same endian format.

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
John

Hi ,
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>

/* ~~ These are the columns for the layout. ~~
1) Padding is only placed on the top and/or bottom of the divs. The elements within these divs have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.
2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a div set to float right). Many times, padding can be used instead. For divs where this rule must be broken, you should add a "display:inline" declaration to the div's rule to tame a bug where some versions of Internet Explorer double the margin.
3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar divs could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.
4) If you prefer your nav on the right instead of the left, simply float these columns the opposite direction (all right instead of all left) and they'll render in reverse order. There's no need to move the divs around in the HTML source.

Using Adobe's CSS templates put you behind the eight-ball from the
start. The tutorial linked to might have been a fairly good and reliable
tactic last year, but I'm afraid it might be a bit obsolete. If you
decide to deploy media queries, please read all of the comments
thoroughly and not just the tutorial.
If you'd like to use a more bulletproof method to support small devices,
we do have a product that will help you:

Using null Layout - Problems

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!

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

A small layout problem...
