Selection problem in JTable

Hello everyone,
I've a JTable,which I'm rendering using my own renderer.When the background of any cell within the table is rendered,that particular row does not get highlighted on mouseclick.However,when only the foreground is set (without setting the background),the row is highlighted.Can anyone suggest anything on this problem.I want the row to be highlighted on mouse click even if the background of the cell is rendered.
thanx in advance.
J.C

Maybe u can use this, but you might want to extend your cell renderer.
[qouote from API docs]
setSelectionBackground
public void setSelectionBackground(Color selectionBackground)
Sets the background color for selected cells. Cell renderers can use this color to the fill selected cells.
The default value of this property is defined by the look and feel implementation.

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!
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.

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

Use a button to select contents in Jtable

I have a jTable which holding a data list, I need two buttons, one is 'up' and one is 'down', to move selections in the jTable. The idea is if a client don't have a mouse, they can use these two buttons to navigate through the jTable.
Problem One: if the jTable is not selected, how can press a button make the first record been selected?
Problem Two: if the jTable is selected, how can press a button move the selection
I tried to mod ListSelectionModel, but I cannot find a method that does this. I thought if I can get this jTable selected (any record), I probably can move the selection by setting the selectionIndex or some...
Thank you

I know what he can do if their is no mouse.
OP can use the Robot class and keylisteners then move the mouse cursor according to which listener method is called and which key is responsible for the call.
I mean this is so brilliant, can you imagine how much money people will save on buying a mouse if this catches on.
I am telling you this is the future, say good by mouse your history now. Hahahaha

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;
}

How to get the default selection color from JTable

Hi, there,
I have a question for how to get the default selection color from JTable. I am currently implementing the customized table cell renderer, but I do want to set the selection color in the table exactly the same of default table cell renderer. The JTable.getSelectionBackgroup() did not works for me, it returned dark blue which made the text in the table unreadable. Anyone know how to get the window's default selection color?
Thanks,
-Jenny

The windows default selection color is dark blue. Try selecting any text on this page. The difference is that the text gets changed to a white font so you can actually see the text.
If you don't like the default colors that Java uses then use the UIManager to change the defaults. The following program shows all the properties controlled by the UIManager:
http://www.discoverteenergy.com/files/ShowUIDefaults.java
Any of the properties can be changed for the entire application by using:
UIManager.put( "propertyName", value );

Select Problem For 'Back Menus' - Zen V P

Just got the Zen V Plus and tried to set the time/date. Followed the 'guide' and after the time/date screen pressed the 'back button'. Got the Set Alarm/Date/Time (etc) menu but when I selected an option (moved joystick down to desired option then pressed the joystick) the time/date display came up and I was NOT ABLE to set the date. Same thing occurred trying to set the date (tried it several times and it worked once .... then attempted again - several times (4) but it only worked once). Turns out I have the same problem with any option in ANY 'back' menu. Suggestion?
Do I have a defecti've unit (can't be the 'operator' who is defecti've! haha)? Should I return it and try another?
Actually not that interested in playing music .... it's more for playing .wma(DRM) book files.

Latest ... updated my firmware (to ZENVPlus_PCFW_P4S_L2___0.exe) and it fixed the select problem for SET DATE/TIME etc however
the SELECT procedure doesn't always work for 'back button' menus. Example: tried to set a bookmark... following procedure in 'guide', pressed 'back button' and held it, from 'NOW PLAYING' screen - works 2 out of 5 times. Most of the time, pressing and holding takes you back to the previous menu - not to the 'back' (or in this case the SET BOOKMARK) menu. Sounds like something for the next version of firmware ... the code doesn't always set an internal timer correctly (am a programmer of 30 years ... part of that time pgmmng firmware).

Print selection problem

when i select a page to be print from my pc the page select in

Hello. I feel your pain and frustration with the print selection problem in safari, especially in Snow Leopard. I have spent hours trawling help pages and forums etc. BUT YEE HAA (sorry got a bit excited, but it really was hours) I found the answer. So here goes.
Click on Safari
Scroll down to services then slide to right
Scroll down to services preferences and click
Scroll down to the Text section
If you Tick the Text box it will choose all options for you. Or if you don't want all options in the Text list, then untick Text box and tick options you do want.
BUT for your print selection problem make sure you tick NEW TEXT EDIT WINDOW CONTAINING SELECTION.
Then when you want to select something in a web page you want to print (including pictures etc) then highlight it, then Right click. And low and behold, in the list is NEW TEXT EDIT WINDOW CONTAINING SELECTION. Click that, Then press cmd+p and your printing.
I really hope that helps with your problem
I can now go to sleep.

Weird BGP path selection problem

Hi, all,
I am seeing a weird BGP path selection problem on 4948 switch running cat4500-entservicesk9-mz.122-46.SG.bin code, this switch has two uplinks to the same ISP's different edge router, one circuit is primary the other one is strict backup, only default route is accepted from ISP. I am setting both local preference and weight to the default route advertised over backup link, however neither one is taking effect, BGP still thinks the backup link is better, what could be wrong?

Thanks

Hi,
On cisco routers , weight is having highest preference to decide best path. By default for received route, weight is 0 but you are setting weight 90 to backup path and that is why it is getting preferred (higher is better). Please remove weight and let local preference be 90 (lesser than route on primary path)

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

Thank u for ur suggestion..

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.
