Hi all! I want to store the results of reading lucene index into jTable, so that I can make it sortable by different columns. From index I am reading terms with different measures of their frequencies.

Hello, I am programming a Matrix Explorer that allows me to reorder the rows and columns of a matrix. The Problem that I have is that I want the drag and drop to be visually consistent, meaning that the rows reordering should be visually similar to the one of the columns reordering( that is already implemented in Jtable). In the Jtable...
I have this JTable on my Swing app with the autoCreateRowSorter enabled. My table only has 3 columns, two strings and one int, it works well for all of them when I click the column headers. However, I'm looking for way to do it programatically. I wanted to set the "initial state" for this table. With the Windows look and feel, the colum...
Hello, I have been stuck on this problem for a while now. I want to drag a row in a jtable to reorder it. But I really want the user to see the row while dragging it and not just the default "drag" rectangle symbol. So I took a look at the java DnD tutorial finding it very useful, but.. The problem is that I still dont know which meth...
Any time I create a custom header renderer for a JTable it ends up not looking correct with the nimbus look and feel. The default table headers have a silvery gradient, custom renderers do not look that way. In the past I just avoided creating custom header renderers. Is it possible to copy the default look onto my new custom renderer? B...
Im creating a table which is dynamically changing its width. And I add columns by time as well. And I have bounded this table to a scrollpane. Here I have set the auto resizing to false in the JTable (else it will fill the whole area from the beginning). And I'm adding images to cells using cellrenderer as well. Now I need to allow use...
Can somebody please explain how I would create row headers? I already have the data and header texts set in the JTable: all I want to know is how I can use a cell renderer to take that first column (i.e. the row header column) and make it look like the column headers (i.e. the first row). Right now its background is white, so it looks ...
This is possibly has a trivial solution, but I am at the end of my tether so I hope somebody can help out. I use a JTable which has a custom renderer and a custom editor for a set of columns. The renderer uses a JLabel component and the editor uses a JSpinner component. Our users want to be able to enter values in a column, and then pre...
Hi All, I have a class that has a Boolean field in it. I display in a JTable a list of of those classes. I created a CustomCellRenderer to change the background color of the rows, so I could have different colors. the problem: when the customrenderer is applied on the Boolean field, (true/false) is rendered instead of the default rende...

I am using 2 Tables (JTable) with their DefaultTableModels. The first table is already populated. The second table is populated for each row of the first table (using an SQL Query). My purpose is to export every line of the first table with it's respective lines of the second in an Excel File. I am doing it with a for (for each line of ...
Hello, I've encountered a strange behavior from JTable (JDK 1.5_22): After a selection change in the table and under some unknown particular circumstances, the JTable will call the cell renderer with 'null' for the value parameter. This will eventually lead to a nice 'Null Pointer Exception' on a custom renderer code that is not ready f...
I found this forum thread which suggests overriding ListSelectionModel to prevent rows from being selected. I would like to prevent selection changes when there are unsaved changes (external to the table) for the currently selected item UNTIL the user confirms the discard. Something like: public class confirmSelectionChange extends Def...
