JTable looses selection

Hi all,
I am working with JDeveloper 9.0.3 and SuSE Linux 8.1. I used jTableName.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION); to make multiple selections in my JTable possible. This works. But the JTable looses its selection when I scroll the table. I saw this working on an other (Windows) machine. Is this a known bug under Linux or what sould I do?
Thanks,
Axel

You may want to upgrade to the latest 1.3.1 on Linux. I haven't seen this myself.

How to set special rows in jtable not selectable

Hello programmers,
anybody knows how to set special rows(p.E. row 0) in jtable not selectable.
in advance thanks for your answers

table = new JTable(...)
     public void changeSelection(int row, int column, boolean toggle, boolean extend)
          if (row == 0)
               return;
          else
               super.changeSelection(row, column, toggle, extend);

JTable custom selection and mouse drag events

Hello
I am currently experiencing a problem when using a JTable and a custom selection. I have made a small example to demonstrate the probem. Selection works for this example by listening for when the user clicks or clicks and drags (button held down) and moves the mouse across cells in the table. For each MouseEvent received in the MouseMotionListener mouseDragged method I store the coordinates of that cell at the point of the mouse and render the cell at those coordinates with a line border allowing a more versatile cell selection. The problem that occurs is when you click+drag and move the mouse fast, it looks MouseEvents are created every x milliseconds so when you move fast there isn't a MouseEvent raised for each cell in the click+drag from A -> B. If you run the following example then click and hold down the mouse button and move fast downwards from the top of the table to the bottom you can see that not all the cells are selected vertically.
Is there someway of increasing the mouse poll (if this is indeed the problem) during the click+drag or a better solution to this problem that any one knows!?
I have tried attaching the example but it exceeded the message length for the forum post here is a link to code
[http://www.oneandonlyluppy.pwp.blueyonder.co.uk/TableTest.java]
[http://www.oneandonlyluppy.pwp.blueyonder.co.uk/TableTest.zip] <-- Contains the source and compiled classes
I'll try adding the code again as a separate post
Thanks

AFAIK the mouse polling rate is OS dependent (being interrupt driven), and may even be affected by processor load. What you could do is store the mouse location (Point) of the last mouseDragged event, and compute a line to the current location, then use some coordinate geometry to identify any intervening cells which are presently being skipped.

How to find out if JTable's selected row is visible?

Hello there,
Given:
a JTable is inserted into a JScrollPane and the number of rows in the table is greater than the vieport size.
A random row within the table gets programmatically selected.
How to find out if the selected row is visible in a JTable visible area?
Your help will be greatly appreciated.
Tim

That will make the row visible, but not answer whether it was visible
in the first place. Try something like:
public boolean isRowVisible( JTable table, int row ) {
    Rectangle rect = table.getBounds();
    int rowHeight = table.getRowHeight();
    int viewHeight = table.getParent().getHeight();
    int max = rect.y - viewHeight + 1;
    int rowPos = - rowHeight * row;
    return ( rect.y >= rowPos && rowPos > max );
}assuming all rows have the same height.

JTable Multiple Selection

Hi,
I am having a problem with the jTable's multiple selection.
I apply cell renderers on a table's cells and also apply cell selection model on the table. I want to have mutliple row selection but I only get single selection.
Could someone please explain why that is?
Thanks

Hello,
Please edit your post and use proper tags.
+if (table.getSelectedRow() == row) {+
From the JTable API Javadoc:
getSelectedRow()
Returns the index of the first selected row, -1 if no row is selected.
So this only returns +one+ index among all those selected.
You could use <tt>getSelectedRows()</tt> (notice the +s+ !) instead, but there's a much better approach: guess what the +isSelected+ argument to <tt>getTableCellRendererComponent(...)</tt> stands for :o)
Regards.

JTable - row selection not working + change the text format

Hi All,
I have written a code to display Jtable with 2 columns, 1 column to display image+text and other is multiline.
I have used 2 different cell renderer for achiveing the same.
Please advice on the following:
@ When I click on row, only one column gets selected. How to fix this?
@ Data to be displayed in rows is fetched from database. And on some STATUS value row should be in bold text or plain text. I have achieved this but withou logic to iterate over it.
@ When user right clicks on the row allow them to set text in the row as bold or plain.(Just like we do with mails in outlook box)

          public boolean isSelectedIndex(int index) { return false; }

Multi Jtable row selection

I am trying to allow a multi Jtable selection :
In a JPanel, boxlayout, I have many Jtables aligned with the Y AXIS (one below the other). They have the same model and what I want is to be able, when I drag an area with the mouse, to select all the rows that are into this area event if the area covers many JTables.
In other words, the user must be able to select rows from differents Jtables as if there was only one Jtable at all.
Do seomeone has an Idea ?

        tcol.setPreferredWidth(10); // tried any other number as well...
        rtrvTable.setModel(temp.getModel());
        rtrvTable.repaint();and on the remove column - it removes it completly - not only hiding it, so I cannot get the value at the column (which I need as it is the PK of the tabe)

JTable row selection

What technique would you recommend to programmatically select one or more rows in a basic JTable?

I used addRowSelectionInterval to get multiple selections. Your note directed my attention to the proper method(s). Naturally I overlooked it on several occasions. Thank you DrClap.

JTable - loosing focus without tabbing out

Hi all,
I have a JTable and when the user goes to enter some text in a field I would like the value entered to persist to the underlying object as soon as the text is changed. This is without the user tabbing out of the JTable.
Currently when a value is changed and the user hits a save button the value is not saved as the focus is still in the table, it all works fine as soon as the user enters the new value and tabs out of the table and then selects save,
Does anyone have any suggestions?
THanks,

This can be done via your own TableCellEditor class. Create a TableCellEditor class. Implement KeyListener in this editor to save whenever the data is modified.
You can set the default editor via setDefaultEditor() on JTable.

Multi JTable line selection

Hi,
How can I get the values of selected rows / columns when more than 1 at a time?
Wha I need is the following:
cell. What I am looking for is the values of
multiple cells as follows:
Col1 Col2 Col3 Col4 Col5
row1 A B C D E
row2 F G H I J
row3 K L M N O
row4 P Q R S T
row5 U V W X Y
when I select (highlight) any number of rows - i
want the values in
the left most column of all these rows. In the above
example I should get:
var1 = A
var2 = F
var3 = K

Loosing selection...

Dear Java Gurus,
Again I have a question. The path to Jedi is a looong one :-)
I am playing around with a default editor kit and a JTextPane/JTextArea. When I select text
inside the text area everything works just fine, but when the text area looses focus, the
selection is cleared. I have noticed that that is not the behaviour in other tools and the
selection is only lost once you create a new one.
What setting or magic do I need to perform to avoid loosing the text selection when my editor
looses focus?
The reasons I am asking is that if I want to implement a button for let's say cutting the
selected text, the selection is lost just when I press the button, leaving nothing to cut out :-)
Quite silly :-)
Please help a confused soul?
Best regards,

Change of Jtable feature select in 1.5?

I have a JTable Object, with 12 columns and 32 rows.
when the user want to populate the first eight rows there is no problem, they begin ant the rown 0 column 0, But when the user want to capture only from the 9 to 16 row, they select those range, but until the version 1.4.2, the cursos was positioned in the first row&colum selected.
But after jdk 1.5.x, the cursor focus focus is in the last row&column selected..
How can I make that the first position select get the focus in the JTable?
In other worksheet have this feature, fouc son the first colun&row selected.
why Java change it?
Please help me out.

The problem is not how to select an interval.
The problem is the position of the cursor when finalizing the selection of an interval.
In the versions prior at the 1.5 was positioned at the beginning of the selection and not to end.
But since version 1.5, the focus on the table have the last position selected.
Look the excel feature or another worksheet, and the focus always is the first cell selected.

JTable about Selection Mode

I need to implement a new selection mode similar to MULTIPLE_INTERVAL_SELECTION but every time the user clicks on the table the entire column must be selected (or deselected if the column was selected before) and the other columns must stayed selected as If control key was pressed without being pressed! Does anyone know how to figure this out?

I have figured it out in a different way... The problem is the way the screen is refreshed... do you know a way to solve this issue?
