Tabbing through cells of a JTable

I have a JTable that has the following columns:
Item, Desc, Qty1, Qty2, Qty3, Price
The only fields that are editable are the Qty columns.
Is there a way to make it so tabbing is only enabled to the Qty columns?
For example, if the the cursor is in the Qty1 column for Item 1, hitting tab would put the cursor in Qty2 for Item 1, then hitting tab again would put the cursor in Qty3 for Item 1, then hitting tab again would put the cursor in Qty1 for Item 2, etc. Basically, I would like the tabbing for the Qty columns only and to ignore the Item, Desc, and Price columns.

Tab through cells in a table created in Pages

In 5.0 when I create a table I cannot tab through the cells. Is there a setting I'm missing here? Why must I use the arrow keys?
Thanks.

Thanks. I hadn't considered that and yes it works but not the same way it did before. Prior to the change if you made a change in the cell you could double tab to move onto the next one. Now you must use option + tab after making the change to go onto the next cell.

Is tabbing through all the active cells of a table possible?

hi...
i need to tab through the active cells which are already not seen on the table. i mean i can only tab through the cells which i see, i need to use the horizontal scrollbar to move to the cells which are not already seen.
can i programmatically change this behaviour?
i used the example program below to disable a part of the table.

then i noticed this behaviour. hope its the same with arrays also.
please reply with your valuable suggestions
thanks in advance

Getting right end of text displayed in cells of a JTable column

Hey All,
Platform: WinXP, Java 5.0.
I have a simple one-column table whose cells contain pathnames of user-selected files. The pathnames may be quite long, and when they're too long for the fixed width of the column (the containing JFrame is not resizable), I want the trailing (right) end of the pathnames to visible (so the filenames are visible) and for elipsis to be used on the left side (omitting root directory, etc., if need be). I can't figure out how to do this. I've tried many different approaches. Currently I use a class that extends TableCellRenderer, but no combination of alignment settings in this class seems to do the trick.
I've noticed that in the case of JTextFields, this manner of display seems to be the default, no matter what alignment setting I choose. I can't seem to get the desired effect with the display of cells in my JTable though.
Anyone have any suggestions?
Thanks in advance.

Great job camickr,
That did just what I wanted; you get the points for sure! I will say that It's surprising to me that Swing leaves so much work in calculation to be done for this simple idea.
Btw, I also want to mention here that there's another forum issue I raised and you responded to recently, and you never quite answered my question there:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=5160875
That's got 10 pts riding on it too, if you care to revisit the issue...
Thanks very much for the good work on the CellRenderer.

How do I change the colour of text in a cell in a JTable?

I am trying to change the color of the text in a single cell in a JTable. I have tried not adding a cell renderer and it changes the colour of text in all cells.
I have tried adding a cell renderer to the table and it does the same ie all cells text colour changes.
I am able to add a cell renderer to a column and it changes all the cells in the column.
I cannot figure out how to change just one single cell's text colour without effecting the other cells.

Ok, so if i create my own cell renderer do I set it as the default renderer for the whole table i.e.
table.setDefaultRenderer(MyCellRenderer, renderer);
Does this set one cell renderer for the whole table or is there an individual one for each cell?

How do I change the colour of a selected cell in a jTable?

I have a Jtable that displays URL names in one column. There are several problems I'm having. The effect I'm trying to achieve is this:
When the user runs the mouse over the URL name the cursor should change into a hand (similar to what happens in an HTML hyperlink). I'm aware that the Cursor class can set the cursor graphic so i figure that i need a listener of some sort on each cell (so the cursor can change from an arrow to a hand) and also one to indicate when the cursor is not on a cell (so that it can change from a hand back into an arrow). Is this the right track?
Also, I've looked at the DefaultTableCellRenderer class (which, as i understand it, is responsible for how each cell in the jtable is displayed) for a method that will allow me to set the background of a selected cell (or row or column). I require this because each time i select a cell (or row) it becomes highlighted in blue. I would rather it just remained white and changed the cursor to a hand. I know there exists a method for setting the background for an unselected cell but none for a selected cell. Again, I'm not sure if I'm going down the right track with this approach.
Lastly, if the cell has been selected (by a mouse click) the font of the writing in the cell (i.e. The name of the URL) should change. This shouldn't be too much of a problem I think.
I do not expect anyone to provide code to do all of this but some general pointers would be extremely helpful as I do not know if I'm thinking on the right track for any of this. Having some (limited) experience with Swing I doubt there is a simple way to do this but I can only hope!
Thanks.

In creating a fillable PDF in XI Pro, can I insert a table which can be tabbed through?

In creating a fillable PDF in XI Pro, can I insert a table which can be tabbed through?

You're in luck. Create the first field and then right-click it (in Form Edit mode) and select Create Multiple Copies. You'll be able to specify how many copies of the fields to generate, and at what intervals. The nice thing is that although the properties of the new fields will be identical to the source one, they'll each have a unique name, so you'll get an instant "table" of fields.

I can no longer tab between cells in a table with pages 5.0.

I use pages everyday for filling in my work booking sheets. I need to have them synching to the cloud, so I can access the client information while on the road.
My booking sheet is basically a large table with many cells for name, address, phone number, etc. In pages 4.3 I could enter some information into the cell, hit the tab button, and it would go straight to the next cell in the table. This was a quick and easy way for me to fill out my forms on the computer.
Well, since the update, the tab button only moves the cursor over in the same cell, as opposed to the next cell. It is VERY rare to need to tab in a cell, as opposed to going to the next cell.
I did figure out that I could Option+ Tab to move to the next cell, but it is very hard to change my procedure of tabbing after all this timing doing it the other way.
Am I just missing a preferance to tab between cells, instead of inside a cell?
Thanks
Dave

Option-tab makes sense and can be done with the left hand's thumb/forefinger.
Using tab was always arse-backwards as it defeated the use of tab within the table cell.
Best to use both for what they always do:
Option tab or an arrow key (singular) to jump cells
tab to jump to the next tab in the text wherever it is within or without cells.
The contrary precedence was set by Microsoft and was a bad idea. In good UI you do not have shortucts reverse roles such that you need to pay excessive attention to the context.

Date field automatcailly changing when tabbing through other scripted fields

I have a form with a datetime field. The object is readonly. I format the field with javascript as yyyymmddhhmmss as a tracking number for the form. When tabbing through other fields with javascript the value changes to the current date time, like the code is being executed each time a scripted field is entered.
Any ideas how to prevent that? I just want the code to execute when the form is opened.
----- form1.sbfDirect_Pay.dteCurrentDate::ready:layout - (JavaScript, client) ----------------------
// Current Date in short-style date format.
// $.rawValue = num2date(date(), DateFmt(1, "))
var varCurrentTime = new Date();
var varYear = varCurrentTime.getFullYear();
var varMonth = varCurrentTime.getMonth() + 1;
var varDay = varCurrentTime.getDate();
var varHour = varCurrentTime.getHours();
var varMin = varCurrentTime.getMinutes();
var varSec = varCurrentTime.getSeconds();
if(varMonth<10) varMonth = "0" + varMonth;
if(varDay<10) varDay = "0" + varDay;
if(varHour<10) varHour = "0" + varHour;
if(varMin<10) varMin = "0" + varMin;
if(varSec<10) varSec = "0" + varSec;
// $.rawValue = year + "" + month + "" + day + "" + hour + "" + min + "" + sec;
dteCurrentDate.rawValue = varYear + "" + varMonth + "" + varDay + "" + varHour + "" + varMin + "" + varSec;

I think I just answered my own question. The code was in the layout:ready event. This area is executed each time the layout is modified. I moved the code to form:ready event.

How to enable JScrollPane in a cell of the JTable

Hi,
I am able to place the components into the cell of the JTable. But I am unable to interact with the components like JTable or JComboBox after inseting them into a cell of the JTable.
This was the one of the Scenario:
Step 1: I created One JTable named as "insertTable"and adding to JScrollPane
Step 2: I'm able to inserted the newly created JTable ("insertTable") in to a cell of another JTable(like table inserting a table) using TableCellRenderer.
here was the problem. I am able to insert the newly created table into the cell. the "insertTable" size is greater the Cell size. So, the "insertTable" is appering with Horizantal and Vertical Scrollbars because the "insertTable" is added to JScrollBar. but I am unable to move the scrollbars.
please any one help me for this.

you still didn't try to learn the difference between cellEditor vs cellRenderer - as you were advised to do more than once in recent posts.
If you do, the answer will be obvious (to you :-). As long as you don't there's nothing to help
Cheers

JComboBox Cell Editor in JTable

I've scouered the forums for an answer to my question, and while
finding other valuable advice, I have yet to find an answer to my
question. But first, a little description:
I have a JTable consisting of 5 columns:
col1= standard Object cell editor
col2= JComboBox cell editor
col3= JComboBox cell editor, values dependent on col2
col4= JComboBox cell editor, values dependent on col3
col5= JComboBox cell editor, values dependent on col4
Data structure looks like this:
col1= company object, containing vector of values for col2
col2= lease object, containing vector of values for col3
col3= well object, containing vector of values for col4
col4= pump object, containing vector of values for col5
col5= simply displayed.
I have a JButton that adds a new row to the table via dialog, then menu
options to add entries to the comboboxes/vectors. The kicker here is
that everything is fine up until I've added a pump, and click the cell
to view the entry. In my cellEditor class, I have a 'getSelected()'
method that returns 'combobox.getSelectedIndex()'. When 'edittingStopped()'
is thrown for any cell in this column, I get a null pointer in my
getSelectedIndex() method of the lease combobox - only in this pump
column. Even the part column works correctly. Code snips:
public class MyApplication ... {
private TableColumn leaseColumn;
private TableColumn wellColumn;
private TableColumn pumpColumn;
private TableColumn partColumn;
private LeaseDropDown leaseDropDown;
private WellDropDown wellDropDown;
private PumpDropDown pumpDropDown;
private PartDropDown partDropDown;
private int currentLease = 0;
private int currentWell = 0;
private int currentPump = 0;
public MyApplication() {
    leaseColumn = pumpshopTable.getColumnModel().getColumn(1);
    leaseDropDown = new LeaseDropDown(companies);
    leaseColumn.setCellEditor(leaseDropDown);
    DefaultTableCellRenderer leaseRenderer =
      new DefaultTableCellRenderer();
    leaseRenderer.setToolTipText("Click for leases");
    leaseColumn.setCellRenderer(leaseRenderer);
    //... same for lease, well, pump, part ...
    leaseDropDown.addCellEditorListener(new CellEditorListener() {
      public void editingCanceled(ChangeEvent e) {
      } // end editingCanceled method
      public void editingStopped(ChangeEvent e) {
        updateCells();
      } // end editingStopped method
    }); // end addCellEditorListener inner class
    //.... same inner class for well, pump, part ...
} // end MyApplication constructor
public void updateCells() {
    currentLease = leaseDropDown.getSelectedLease();
    //... get current well, pump, part ...
    leaseDropDown = new LeaseDropDown(companies); // companies=Vector,col1
    leaseColumn.setCellEditor(leaseDropDown);
    //... same for lease, well, pump and part columns ...
} // end updateCells method
} // end MyApplication class
public class LeaseDropDown extends AbstractCellEditor
    implements TableCellEditor {
private Vector companiesVector;
private JComboBox leaseList;
public LeaseDropDown(Vector cVector) {
    companiesVector = cVector;
} // end LeaseDropDown constructor
public Component getTableCellEditorComponent(JTable table,
      Object value, boolean isSelected, int rowIndex, int vColIndex) {
    Company thisCompany = (Company) companiesVector.get(rowIndex);
    Vector leasesVector = (Vector) thisCompany.getLeases();
    leaseList = new JComboBox(leasesVector);
    return leaseList;
} // end getTableCellEditorComponent method
public Object getCellEditorValue() {
    return leaseList.getSelectedItem();
} // end getCellEditorValue method
public int getSelectedLease() {
    JOptionPane.showInputDialog("Selected lease is: " +
      leaseList.getSelectedIndex());
    return leaseList.getSelectedIndex();
} // end getSelectedLease method
} // end LeaseDropDown class... LeaseDropDown can be extrapolated to well, pump, and part,
handing well the selected lease, handing pump the selected
lease and well, handing part the selected lease, well and pump.
I guess my question is how do I get the selected comboboxitem (I'd
settle for the entire combobox if there's no other way) to fill in the
next column? Why does the way I have it now work for the first 2 combobox
columns and not the third?

I'll try to provide more details.
I use a JComboBox implementation as a cell in a JTable. The CombBox is editable . This is what I get when I try to type in something.

Issue tabbing through form fields on Adobe Reader 9.2

Hello everyone. I am having an issue that I am hoping someone can assist me with. We are currently using IE6 and Reader 5.5 in our production environment and we are currently testing IE8 and Adobe Reader 9.2 for deployment. Our company uses a web portal where we have many pdf forms that open within a web browser. The problem we are experiencing is that when tabbing through fields on the pdf, the cursor will eventually cycle down to the end of the form and then start cycling through to the top of the browser (toolbars, address bar, search bar,etc) before finally returning to the pdf document's fields. Is there either a setting in the reader or maybe even IE which controls this functionality and will limit the tabbing to only the pdf form? Or does anyone know of a method of limiting the tabbing functionality to only work within the pdf document itself when opened within a browser?
Any help on this is greatly appreciated. I have looked through all the reader preferences and do not see anything directly related to this. Thank you very much in advance.

I guess by QTP you mean HP Functional Testing 11. This is really something to take up with HP, it's the job of monitor software not to crash.
