JTable Model -- How to set the width of columns

Hello,
This project of mine is due in 2 days. :(
I am using AbstractTableModel and I can't figure out how to set the columns' width inside my JTable?
This following code does not work.
int vColIndex = 1;
TableColumn col = table.getColumnModel().getColumn(vColIndex);
int width=399;
col.setPreferredWidth(width);Please remember, that I'm using AbstractTableModel and not just simple JTables.
Thanks in advance.

The DataModel (AbstractTableModel or otherwise) has nothing to do with the table column size. The DataModel is used to store data.
When you create a JTable using a DataModel then a TableColumn is created for each column in the DataModel using a default column size. The normal order of creation would be:
TableModel model = new DefaultTableModel(...);
JTable table = new JTable(model);
Now that the table and table columns are created you can change the size of the columns:
int vColIndex = 1;
TableColumn col = table.getColumnModel().getColumn(vColIndex);
int width=399;
col.setPreferredWidth(width);
So your code looks ok.
However, if somewhere in you code you do:
a) table.setModel(...)
b) fireTableStructureChanged();
then the table columns are recreated based on the current DataModel and the table column size would be reset to the default values.

How to set the width of DataGridColumn dynamically?

What I want to do is, load data from a text file and put into a DataGrid component, the fields of ech record in the text have fixed length, and are seperated by a space, like this:
personal.txt
50 Uvwxyz Male    123456789
60 Hijklmn Male    67890123456789
30 Abcdefg Male    123456789012345
40 Opqrst   Female 987654321012345678
the configuration file is column.xml:
<dgcolumn>
     <personal>
          <len>20</len>
          <title>Name</title>
     </personal>
     <personal>
          <len>3</len>
          <title>Age</title>
     </personal>
     <personal>
          <len>6</len>
          <title>Sex</title>
     </personal>
     <personal>
          <len>20</len>
          <title>IdNumber</title>
     </personal>
</dgcolumn>
First I load the column.xml into an arrColumn, then read the personal.txt and seperate the record by the width( "len" in the xml file ), and put the seperated fields into another arrField, set the arrayFld as the dataProvider of a DataGrid, thus, the title can be showed as the headerText of the DataGrid and the data can be loaded correctly.
private function handleComplete( event:Event ):void
     var arrField:Array = new Array();
     var arrFile:Array = loader.data.split(/\n/);
     for( var i:int = 0; i < arrColumn.length; i ++ )
          arrField[i] = convIcom( arrFile[i] );
     adgFile.dataProvider = arrField;
     trace( "The data has successfully loaded" );
private function convIcom( strRecord:String ):Object
     var key:String = null;
     var dataField:String = null;
     var offset:int = 0;
     var obj:Object = new Object();
     if( strRecord.length > 0 )
          for( var i:int = 0; i < arrColumn.length; i ++ )
               dataField = strRecord.substr( offset, arrColumn[i].len );
               key = arrColumn[i].title;
               obj[key] = dataField;
               offset += arrColumn[i].len + 1;
     return obj;
<mx:DataGrid x="10" y="100" width="400" id="dgFile" />
The problem is, the width of the DataGridColumn is average, how to set the column width by the length of each field? I can calculate the rate of each field ( field / fields ), but I don't know how to change the property of the DataGridColumn.width.
Thanks for helping.

In the above post, I pasted an old version of personal.txt, so I paste it again:
personal.txt
Uvwxyz 50 Male   123456789
Hijklmn 60 Male   67890123456789
Opqrst 40 Female 987654321012345678
Abcdefg 30 Male   123456789012345
And I have another question, when the data is loaded into the DataGrid, the fields of each record are ordered in alphabetical order ( the "Age" column will appear firstly, then "IdNumber", "Name", "Sex" ), not as the order in column.xml, how to make it keep the sequence of the xml file?
Thanks again.

How to set the width of a cell in JTable?

I have created a JTable and I want to set the width of cells.How can I do that?

This is now the third person to tell you that Swing questions should be posted in the Swing forum.
You have several postings out there where you have been given an answer but you haven't bothered to respond to the posting. Indicating whether the suggestion was helpfull or not. I guess you really don't want help from people in the future.

How to set the width of a shuttle?

Hi
I have a group which is shown in intersection-shuttle style but the problem is that it breaks some rows into two lines and i want to make the shuttle a bit wider. How could I set the width of the shuttle. Apparently the Group Width attribute of the group doesn't work for this.

You could try this using the inlineStyle property of the shuttle component in the generated page. Not sure that works though. You better ask this on the JDeveloper forum.
If it works you can create a custom template to include the inlineStyle property during generation.

How to set the width: IF_WD_SELECT_OPTIONS- add_parameter_field

Hi everyone,
I would like to know if there's a way to set the width of UI controls defined for IF_WD_SELECT_OPTIONS.
In particular I've created a selection screen using
wd_this->m_handler_simple_left->add_parameter_field( i_id = 'CONTRACT_DESCRIPTION' i_value = lr_field
i_description = 'Contract description'
i_within_block = 'BL01' ).
but I'm unable to set the width of this field and the final rendering isn't very nice at all (all input fields have different data types and different size).
Thank you.
Regards

Hi,
I think we dont have any width type parameter to set width in selectoptions. The width comes directly from Domain.
Cheers,

How to set the width and heigh in the popup window

Hi All,
I tried to show a report in a popup window style.
In the column link section, I defined the URL like the following:
javascript:popupURL('f?p=&APP_ID.:128:&SESSION.::&DEBUG.::P128_PAY_RATE,P128_PAY_TERMS:#PAY_RATE#,#PAY_TERMS#'). how and where to set the height and width for page 128?
Thank you,
spark

Here is a sample of the JavaScript function I re-use that opens a popup window. You'll notice that it includes the width and height of the popup window:
function callTCPopup (formItem1) {
var formVal1 = formItem1;
var url;
url = 'f?p=&APP_ID.:1111:&APP_SESSION.::::P1111_TC_ID:' + formVal1;
w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
}You could also look at using a Modal Page (Skillbuilders' plugin - watch the video for use).

How to set the row height in a JTable

Is there a way to set the height of a row (actually all rows) in a JTable?
I have tried setting the font to be bigger but then the cells are not big enough.

Use "rowHeight" method of JTable class.
