Colum Resizing problem in JTable

HI All,
I am facing a problem with JTable while resizing the colum. when user clicks and drags to resize a column, the column width increases continuously till the mouse button is released. I am sure this sounds like a vague description,
(eg)
when I click on a column boundary and drag, the column width is getting increase beyond where the cursor of the mouse is. In a normal table, when I click and drag, the column resizes to the size that I have the mouse position at, and gets set to the width when I release the mouse. But right now, when I click the mouse and drag to say a width of 50 from 10, it is still increasing beyond 50 and stops when I release the mouse at about 100 or higher. I hope this is a clearer explanation.
In Java 1.2, it works fine. but in java 1.4...
If Anyone knows, please let me know
Advance thanks for any comments and suggestion..
Best Regards,
Muthu

I solved this problem... Problem is getPreferredSize() method. I override this method
Thank u for ur suggestion..
Best Regards,
Muthu

What method should be used for resizing the particular JTable Column width

I have a four table. Only one table which are on top have a table header. I want that when user resize the topmost table with a mouse other table colume also be resized automatically. So I want to know that what method should be used for resizing the particular JTable Column width.
Thanks
Lalit

maybe you can implement a interface ComponentListener as well as ComponentAdapter with your topmost Table.
for example:
toptable.addComponentListener(
new ComponentAdapter(){
public void componentResized(ComponentEvent e){
table1.setSize(....);
table2.setSize(....);
/*Optionally, you must also call function revalidate
anywhere;*/
);

Problem of JTable's column setPreferredWidth.

Hi All,
I have a problem about JTable,I want to set the preferredwidth for every column when the table is first established,but it is always failed.
Could someone tell me the root?Thanks!

Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
The problem is that the size of the frame is greater than the size of the table so the widths of all the columns get adjusted after you specify the original default size.
Your code should be something like:
typeTable.setPreferredScrollableViewportSize(typeTable.getPreferredSize());
JScrollPane typeTableScrollPane=new JScrollPane(typeTable);
mt.pack();
mt.setVisible(true);Or you might be able to use my [Table Column Adjuster|http://www.camick.com/java/blog.html?name=table-column-adjuster] which will resize the columns automatically.

Hi!!! A Problem in JTable

HI,
I have a problem in JTable.I have a Jtable and a button named validate.My JTable first displays a set of rows and colums.if we name the colns as a,b and c. when i click the validate button i will take the values of a1 and b1 and do some validations. If it is in correct position then the row remains as it is else i will change the value of b1 to a1 position and vice versa. This happens in a loop till the end and the data vector of the table gets changed accordingly.Now the problem is suppose if there are 10 rows and the value changes in row 1,5,7 thn i need that rows alone to be colored while the button ends its action.Finally the JTable should be viewed as row 1,5,7 colored and others in their default color....
Please help me...

You will have to create your own Renderer or use a table like JXTable from swing labs that allows highlighting.

Problem with JTable in a JScrollPane

Hello all,
I have a problem using JTable, that the number of columns is very big,
and the JScrollPane shows only vertical ScrollBar, isn't there any way to show a horizontal ScrollBar, to show the other columns without being bunched.
Thanks in advance.

table.setAutoResizeMode( JTable.AUTO_RESIZE_OFF );

Selection Problem with JTable

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name |   Type |   ...
--------------|---------|---------------------
Hotmail       |   POP3 |
GMX           |   IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!

[SOLVED] GNOME 3.8 annoying window resize problem

Hello all fellow early-adopters :-)
A very annoying quirk I've noticed, moving from GNOME 3.6 to 3.8, is that it no longer remembers, nor retains, the size/positions I set for many of my application windows. For example, my mail client (Evolution) is sized to fill most of my screen (centrally), with Empathy and Skype as long narrow windows on both sides - giving me a nice, broad "communications" overview on that particular desktop (with dev tools etc open on others).
On 3.6, this layout was retained during my session, as well as next time I started these apps up.
In GNOME 3.8, not only does it insist that these windows are always started as small little bunched-up windows that I need to resize, but every time a window displays a notification/warning (message in internal yellow bar inside the window - such as loss of internet connection, mail retrieval failure etc) it resizes the windows spontaneously to a stupid, small size that overlays the other windows. This is driving me crazy!
Where can I learn a bit more about how window sizing / positioning works in GNOME 3.8, or is it finally time to switch to awesome wm? I want to love GNOME 3.8, I really do. It's so slick, but so... unpolished.
I want to dig in an assist with problems like these, but I need some pointers to some background material first to understand the problem. Is it the window manager? Is it the app?
** UPDATE: Doing a full system upgrade, as of May 18, 2013, has resolved this annoying problem. My windows now stay where they belong, and start with the same size they were closed with. GNOME is now pleasant to use again :-)

I really like GNOME 3.x though (and would like to understand the windowing behaviour), but if the annoying quirks are insurmountable, I will happily switch.
Man I love GNOME 3.x. I admire the courage they had to change, basically, everything, and I find myself more productive with my GNOME 3 Arch box than with my good ol' Slackware KDE 4 box. I just hate those bugs - for example I filed a task in their bugtracker for this window resize problem I have with gedit. If it's a love/hate relationship, I think it's marriage ^_^
With the 3.8 upgrade, deadbeef was having a similar problem with window size/position. I just recompiled it against the latest GTK+3 package upgrade (that came after the 'big upgrade' here on Arch) and it was fixed. But not with gedit

Man I really hope this gets fixed soon, because aside from this one incredibly annoying issue I am loving gnome 3.8.
I get the feeling gnome badly needs more beta testers, sizable regressions like this in "stable" releases happen way too often sad.
I get the exact same feeling. Well bugs exist everywhere, there's no denying. But I think it would be wiser to 'alternate' the nature of each major stable release - one focusing on new features and one focusing on fixing bugs. For example if the only new features in GNOME 3.10 were the AppsFolder full implementation and the introduction of gnome-calendar, and the rest of the development cicle being devoted to fix bugs, I'd be more than happy.
Like Fedora and Ubuntu, the fixed 6-month release cycle colaborates with the bugs. They don't do like Debian or Slackware which are released 'when they are ready'.
EDIT: fout (yet) another bug. At least with facebook chat (haven't tested with other telepathy plugins) the buddy tray icon appear duplicate. Anybody with the same issue?

Problems with JTable

Hi All,
I am facing some problems in JTable :
1) How to remove all lines between cells, neither i should have column nor row lines....there should not be any lines between any cell at all.
2) If i select a perticular cell, complete row is getting selected with a blue background, that should not happen at all.....row should not get select....
3) How to make a cell non editable.
Regards,
Ravi

1) Read the API. Check out the set??? methods until you fine what you want
2) Read the API. Check out the methods that deal with row and column selection
3) Override isCellEditable(...) method of JTable or DefaultTableModel

JCheckBox clicking problem in JTable

Hi,
I have a column of JCheckBox in a JTable. The JTable is only used to layout the controls(for lagecy reason). The JCheckBox has an item change listener attached. The problem is that OCCASIONALLY when the JCheckBox[i] was clicked, the debug in itemStateChanged show the source object was NOT JChechBox, it was JCheckBox[i+1] or JCheckBox[i-1]. In other word, it was the check box in the previous or next row changed state.
Has anybody experienced similar problems? Is it a problem of JTable dispatching mouse click event?
How to solve the problem?
Thanks

I'm not sure why you get the results you do, but instead of adding a change listener to the JCheckBox you could add a TableModelListener to the TableModel. This will fire an event whenever any data is changed. This thread shows a simple example:

Preview Application Resizing Problem

Preview Application Resizing Problem
Microsoft platforms have two significant advantages. The first is the concept of an operating system that can function with hardware that ranges from cellular phones to desktop computers. The second is that Microsoft has excellent software development tools
for creating and testing computer programs.
Software compatibility across hardware platforms requires not only meeting CPU and memory requirements. Application programs must be able to automatically adjust Window and control sizes to meet the needs of available window sizes, video display unit sizes
and screen resolutions, switching between vertical and horizontal viewing, vertical and horizontal scrolling, changes in font sizes , and variations in the available screen space due to usage of vertical and horizontal toolbars.
Software developers must be careful that resizing doesn’t squeeze controls too close together or make them so small that they cannot be finger or stylus selected when used with touch screens.
Some of the required automatic resizing options are provided by the Microsoft software compilers and the Windows operating system. Softgroup Component’s “.NET Forms Resize” is an example of one of the third party applications that provide advanced
resizing functionality.
Many of the resizing functions are programmer options and, if not properly enabled, an application may not have the required resizing functionality. At the current state of the art, application programs are highly variable in their capability to do the “intelligent
resizing” that is required to handle different display environments.
A case in point is the Microsoft Preview Application for Windows 10. When entering lengthy comments, the send button becomes positioned off the end of the program window. It is possible to scroll to the button, but the display automatically resets when scroll
is released. The result is that the text cannot be sent. You can try a "blind" TAB to the SEND button. This appeared to work after several tries, but the comment was apparently not received,

Cell Editor Problem in JTable

I have a problem using JTable. I have a requirement like each specified cell will have different editors like JtextField or Jcombobox as per some condition. I am building the rows at run time. Number of rows may vary as per condition.
can anyone guide me what to do?
thanks

Override the getCellEditor(...) method to return the appropriate editor.

However I don't think it's a hard problem....
I want ask to you if you have found some problems when you are in Editing mode in a cell.....
in the jdk1.2 version I could save while was in editing mode using the editingStopped method.
It permit to update all data .... also the data in the cell I was editing.
in the jdk 1.3 if I use this method It doesn't work properly... It maybe destroy the content object in the Cell..... because I'm able to print all the table except the editing cell (it throw an exception...)
What's changed????
I don't know...
Can u help me?

Illustrator Resizing Problems

I am having reduction resizing problems in Illustrator CS6. E.G. Straws & lemon wedge rinds become significantly proportionately wider when reduced. Also, numerical text does not skew with everything else. I have a CC membership w/PS & Ai installed. There are no other Adobe items on my 8 month old imac, Lion 10.7.4 except Flash player & the Adobe Applications Manager. Additionally, I have no 3rd party plug-ins & deleting the prefs file does not fix the problem. Any help on this matter would be greatly appreciated.

sgem,
And untick Align to Pixel Grid if ticked (you can do it in the Transform panel, or search for it in the Helpfile).
Hi Steve. Still summer?

A problem with JTable

Hi !
I have a problem with JTable - would like to use this component as a simple list of rows taken from a database : don't want to be able select or set a focus to a column - want only to be able select and set focus to a row ( just like in the menus). How to disable "focusability" for a cell with JTable ? Could You help me ?
thnx in advance

The Border is changed by the renderer, depending on whether the cell has focus or not. So you will need to create custom renderers without a Border. Something like:
class NoBorderRenderer extends DefaultTableCellRenderer
     public Component getTableCellRendererComponent(
          JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
          super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
          setBorder(null);
          return this;
}
