Default table cell renederer get Methods

If I use a JComboBox as a cell editor in a JTable, is there a way I can use the .getSelectedIndex(); function on that editor? Also, with a JCheckBox as the renderer, How would I use the .isSelected(); function? Thank you!

You don't query the editor to find out its value. You query the TableModel.
When you select an item from the combo box the item gets saved in the TableModel. So you just use table.getModel().getValueAt(...).
Same with the check box. A Boolean value will be stored in the TableModel.

How to get the data from a table cell

Could somebody suggest me how I can get the data value from a table cell if I set that cell a Double object previously.
Thanks very much

Thanks for camickr's information.
And thanks uhrand,
I haven't got it sloved. I am sick on this problem.
I have the methods to let the table editable. My tableModel code is from Sun Tutorial.
It has the code like this:
public int getColumnCount() {
            return columnNames.length;
         public int getRowCount() {
            return data.length;
          public String getColumnName(int col) {
            return columnNames[col];
         public Object getValueAt(int row, int col) {
            return data[row][col];
         * JTable uses this method to determine the default renderer/
         * editor for each cell. If we didn't implement this method,
         * then the last column would contain text ("true"/"false"),
         * rather than a check box.
        public Class getColumnClass(int c) {
            return getValueAt(0, c).getClass();
         * Don't need to implement this method unless your table's
         * editable.
        public boolean isCellEditable(int row, int col) {
            //Note that the data/cell address is constant,
            //no matter where the cell appears onscreen.
            if (col < 1) {
                return false;
            } else {
                return true;
         * Don't need to implement this method unless your table's
         * data can change.
        public void setValueAt(Object value, int row, int col) {
            if (DEBUG) {
                System.out.println("Setting value at " + row + "," + col
                                   + " to " + value
                                   + " (an instance of "
                                   + value.getClass() + ")");
            data[row][col] = value;
            fireTableCellUpdated(row, col);
            if (DEBUG) {
                System.out.println("New value of data:");
                printDebugData();
        public void printDebugData() {
            int numRows = getRowCount();
            int numCols = getColumnCount();
            for (int i=0; i < numRows; i++) {
                System.out.print("    row " + i + ":");
                for (int j=0; j < numCols; j++) {
                    System.out.print(" " + data[i][j]);
                System.out.println();
            System.out.println("--------------------------");
        }

Getting text to the top of a table cell

I'm sorry, I have asked this before but I still have nothing that works.
In a table I want the text to start at the top of the cell. I can force it with a clear gif and the end, but surely that is not right. It often works OK in Safari and Opera, but not in Firefox or IE.
I have copied some code below. It seems to me that the text should be aligning top, but it remain vertically centred in live view and all browsers (MAC).
What am I not seeing?

The default alignment in a table cell is LEFT MIDDLE, i.e., left horizontal and middle vertical. If you have no specification in your code for anything other than that, then that's what you get. I see no such specifications in your code, so your symptoms are not surprising. To make things align to the top of a table cell (in HTML4.01) you would use <td valign="top"> or in XHTML you would use CSS to bring the content to the top of the cell, e.g., <td style="vertical-align:top"> (inline CSS shown for clarity).
Be aware that text contained within a paragraph or an <h#> tag WILL HAVE A TOP MARGIN, so if you want that text to be flush with the top of the cell, you will have to control that top margin on the container tag, too.
In your case, I'm assuming that this is one of your attempts to get to the top of the cell -
<td><h1 class="top">Text test header</h1>
But we have no idea what rule is specified by the class="top". At any rate, you will have only affected the alignment of the text within the <h1> tag and not within the table cell by that. Perhaps <td class="top"> would be better? But best would be (if you wanted ALL content in the table to be at the top of the cells) to use a descendent selector like -
table#whatever td { vertical-align:top; }
and then give that table the id="whatever".

Problems with vertical cell borders and the default table style

When laying out tables in Word, I like to use thin horizontal lines (cell borders) and thick-ish white vertical lines. The vertical white cell borders create a subtle negative space that is less cluttered than the typical boxed-in-all-sides style.
Issue 1.
In Pages, horizontal cell borders seem to take precedence over vertical cell borders so my vertical white line trick doesn't work. Is there a way to force my vertical white cell borders to "show up" over my think black horizontal cell borders?
Issue 2.
So, for the time being, I'm not using vertical white cell borders in tables; instead, I set the vertical cell borders to "none." Unfortunately, when I try to set the default table style using a table with no vertical cell borders, Pages adds the vertical cell borders anyway. Does anyone know a way to get Pages to surrender?

I checked and here, aftere defining a new default format with vertical lines set to none, this format is used when I cvreate a new table.
But the same with horizontal lines doesn't apply.

Thanks Peter
Can you just walk me through dumping Pages 5 and getting to the Applications/iWork folder - and does this mean that when I see future Pages Upgrades I should block them?

MVC Problem with getter method of table attribute in model class

Hi,
I am on 620 SP34. I am writing a bsp application with mvc. One of the model classes has an attribute of type table. I use this attribute in a htmlb-tableview and '//MODEL/ZMY_TAB' for data binding. If I try to activate a getter method for this attribute, the application dumps with exception <i>BSP exception: Structure component with name "ZMY_TAB" does not exist</i>. I find the SAP source, that raising this exception (see below). The source code looks like: <i>"I don't support getter methods for tables in attribute path"</i>! The setter method works fine, so I am at a loss. Has anyone of you wrote a getter method for an table attribute in bsp-mvc? Have I to consider anything special?
Thanks,
Carsten
Main Program CL_BSP_MODEL==================CP
Source code of CL_BSP_MODEL==================CM00Z
METHOD IF_BSP_MODEL_BINDING~GET_ATTRIBUTE_DATA_REF
       * check if attribute exists for binding!
         if exists_attribute( l_name ) is initial.
           return.
         endif.
* setter or getter defined? Not supported for DATA REF requests
         if get_getter( attribute_name = l_name ) is not initial.
           raise exception type cx_bsp_inv_component
             exporting name = l_name.
         endif.

You have two options:
1. Make your attributes public. It should work fine.
2. If you need to process the attribute values before it is used, you can make the attribute private but will need three methods
GET_T_ZMY_TAB that returns the table
SET_T_ZMY_TAB that sets the values
GET_M_T_ZMY_TAB that returns DDIC information about the attribute. The same holds good for structures(Change to GET_S_ and GET_M_S_ ) and simple attributes(Change to GET_ and GET_M_).
The set and get methods are kind of documented at http://help.sap.com/saphelp_nw04/helpdata/en/fb/fbb84c20df274aa52a0b0833769057/content.htm but there is no mention of the GET_M_ methods. I could not find one single document on the Model part MVC.
Once I added the GET_M_XYZ methods to my attributes, my BSPs started to work fine.

How to get name of table cell ? Also, how to set name and label property on table itself?

I am trying to use below API:
PMString tableName = "myTable";
ErrorCode error = Utils<Facade::IPageItemNameFacade>()->SetUserAssignedPageItemName(tableUIDRef, tableName);
But this is not setting up the table name, also I am getting error = 1.
Also, I am not getting the API to get the name of table cell(which is the read only property)

Hello kapoor_aman27,
a table is not a page item. The page item name is stored in the interface IPageItemName of the kDrawablePageItemBoss. So you must get the page item of your table and set the name of the page item.

Getting rid of blank table cells

I am currently making an address book and have had to occasionally remove names from the listings. What this means is that there are now blank cells all through out my address book. How can I remove those cells?

I am surprised that Word would be much smarter at doing this; InDesign has had the tables feature for qutie a while now I would have thought they would have worked this out by now.
<cough>
Corrupt tables are pretty much the primary cause of corrupt Word documents. I've never seen a table cause a corrupt InDesign document. Word allows a lot of table-mangling, but I'd say that giving table-manglers what they want is the exact opposite of "smart." Tables in Word are pure hell. InDesign's table implementation (purchased from a third party plugin developer, if I recall correctly), while not as... er... flexible as that of Word, is far more stable. I guess it depends on what you think is smart.
Anyhow, back to what you want:
The reason I designed it using tables like this is because this is the way that my client said they wanted it to be.
Well, I hope you bill hourly. There is a way to automate this, I think, using InDesign's Data Merge feature. If you aren't billing hourly, then it may be worth setting up - moving all of the content into an application like Excel, a spreadsheet app where it's really easy to do address-book-entry-management the way you want, and does not induce corruption when you have to spot-delete individual cells, unlike some other apps I can think of. You can then save a file out of Excel, and InDesign can automagically fill up your tables with content from your Excel file, with no gaps. When your client wants changes, then you just tweak your Excel file a bit, export, and then run the Data Merge to get your gap-free table back.
However, that'd be a lot of work, and I can't even guarantee that it would work, never having tried it. But it's where I'd go in your shoes if my dataset wasn't this small:
my list of names is relatively short so cutting and pasting shouldn't take too much time.
Lastly, I think that your client might not care about whether or not they're in table cells; they just want it to look that way, right? If so, there are many, many ways to set up your doc that don't involve tables, that still yield the desired appearance. If you want to go in that direction, I can toss out a few ideas - I think that Rik already has, although his suggestion is a little bit low on detail.

Get the handle to the table cell button

Hi,
I need to get a handle to a button which is itself is table cell - please have a look at the xml below.
How do I get a handle to a button which has id "EamSubmitButton" below?
Thank you
Anatoliy
<ui:tableSelection>
<oa:multipleSelection viewName="EAMIssueMaterialResultTableVO" viewAttr="Selectflag" id="FndSelectCheckbox" user:akAttributeCode="FND_SELECT_CHECKBOX" user:akAttributeApplicationId="0">
<ui:contents>
<oa:selectionButton text="Issue" id="EamSubmitButton" textTranslationExpansion="100%" user:akAttributeCode="FNDBUTTONCELL" user:akAttributeApplicationId="0" use="/oracle/apps/fnd/attributesets/Buttons/Submit"/>...

Ajay and Anil,
Thank you for responding.
In my case it is customization (extension, R12.1.1)
I have a custom region with a button A.
And I have a seeded page where I have a table with a button (id=EamSubmitButton) contained within a table cell - this is a piece of xml that I quoted before:
... <oa:selectionButton text="Issue" id="EamSubmitButton" textTranslationExpansion="100%" user:akAttributeCode="FNDBUTTONCELL" user:akAttributeApplicationId="0" use="/oracle/apps/fnd/attributesets/Buttons/Submit"/>
</ui:contents>
</oa:multipleSelection>
I need to toggle Disabled property of button "EamSubmitButton" when button A is clicked.
And I don't know how to get the handle to this "EamSubmitButton" button so that I can set it's Disabled property to true or false.
Normally I would get the handle off the bean by way of webBean.findIndexedChildRecursive.
But this doesn't work in this case. I get null.
Please let me know if you have any ideas.
Thanks
Anatoliy

How Do I Change the Padding in Table Cells

Hi, I am trying to set up a table that will allow text to fill the entire cell. I know that if I double click an individual cell, the left and right boundaries of the cell will be displayed on the ruler. However, I can't select multiple cells (even in a column) to adjust the boundaries. By default, all cells are created with no padding on the left, but half an inch on the right. I want no padding on the right as well. I know I can change the the tab for the table with the text inspector, after the fact.
So, #1. How can I change the default right cell wrap for all cells in a table?
Additionally, I know how to get rid of the padding above the text (via text property "instant margins"), but I also need to eliminate the padding at the bottom of the text. When I adjust the instant margin, it just moves the text the upper-left corner of the cell, but does not change the vertical size of the cell. I can change the individual row height by grabbing the border and dragging it up, but, again, this is a pain for large table. I know I can also change the overall cell height by dragging the lower table boundary.
#2. How do I change the default cell height so the cell is tight against the text, regardless of the font size, for all cells in a table?
Any help or suggestion will be greatly appreciated.
Thanks
Gary

Thanks for the reply.
Unfortunately, those options will not do what I need.
If I turn off "Wrap text", the text overflows the cell and the text in the adjacent cell to the right will hidden. I still want the text to wrap, just not half an inch from the right border.
And the "Resize to fit" changes the cell width, which I want to keep the cell at a static width.
One workaround I found, was to modify the table as needed, using text properties, and then save the table as the table default. Unfortunately, that overwrites the factory default, and new table's tabs in other templates (all other properties seem to be retained)
The second option that seems to work, is to save my entire document as a template. That seems to hold all the properties for graphics, tables, etc.
A bit kludgy, but those methods seem to do the trick.
Now, how do I get the default table properties back?

Inline Error Message in a table cell

There is a requirement where in an error message is to be thrown in a table cell.
(For eg, when the filed value is getting populated from a VO.Considering the scenario where the value is null for some reasons.)Can anyone suggest to implement the same?

It is possible with the controller coding.
User putAttrDialogMessage method on pageContext.
public void putAttrDialogMessage(OAWebBean webBean,
OAException message)
Registers a dialog message for a web bean that is not based on a view object. The dialog message will be displayed in the message box located in the top section of the current page and also attached to the corresponding region item as an inline message.
The proper way for preserving the bad value which caused the exception is by using OAAttrValException as follows:
OAMessageTextInputBean textField = ....; // webBean in question
OAAttrValException attrEx = new OAAttrValException(
OAAttrValException.TYP_VIEW_OBJECT, // Just default it to ViewObject
null, // View Usage Name as null
null, // The primary key as null
textField.getDataAttributeName(), // The attribute name
value, // The attribute bad value which caused validation failure
"FND", // Message application short name
"ATTR_EXCEPTION_MSG"); // Message code
pageContext.putAttrDialogMessage(textField, attrEx);
Parameters:
webBean - the web bean to which the message belongs
message - an OAException object representing the dialog message. An appropriate message type must be set on the exception object through the constructor.
Do let me know if you got struck.

Table cell renderer works with any L&F, but not with Windows

Hi,
I created a table cell renderer / editor for a combobox in a table cell. This works all as expected, but if the Look&Feel is com.sun.java.swing.plaf.windows.WindowsLookAndFeel, which is the system L&F on Vista, the selected values in the combobox are not shown in the cell after loosing focus. Metal LF and Motif LF work, and a third party one "TinyLF" works as well.
Can anyone imagine why, and what needs to be changed to get a cross platform consistency without Metal LF?

}

1) Your custom cell renderer does nothing extra, so you can depend on default renderer.
2) Instead of extending JLabel and implementing TableCellReneder, you should extend DefaultTableCellRenderer and override its get renderer method because DefaultTableCellRenderer itself extends JLabel and aditionally it does some optimizations etc., which you can miss if you implement your own renderer.

JTABLE Number Editor - Table Cell Renderer Clash

Hello gentlemen,
I have a JTABLE with an editable column 1. I implement a number editor and a table cell renderer (pls see below) to this column. I apply the setClickCountStart(2) method to the number editor in order to render each cell in the column editable only after two clicks. However, I believe setClickCountStart(2) is somehow overridden by a "default" functionality in my
CustomTableCellRenderer.
My problem is that any cell I select (click only once) in column1 is automatically editable whereas I only want a cell to be editable after two clicks.
Please see my code below. Any comment is more than welcome!
Cheers.
hoodNumberEditor = new NumberEditor();
        hoodNumberEditor.setClickCountToStart(2);
        class CustomTableCellRenderer extends DefaultTableCellRenderer {
            public Component getTableCellRendererComponent(JTable table,
                    Object obj, boolean isSelected, boolean hasFocus, int row, int column) {
                Component cell = super.getTableCellRendererComponent(
                        table, obj, isSelected, hasFocus, row, column);
                if (isSelected) {
                    cell.setBackground(Color.white);
                    cell.setForeground(Color.black);
                return cell;
       CustomTableCellRenderer customrenderer = new CustomTableCellRenderer();
        table.getColumn(1).setCellRenderer(customrenderer);
        table.getColumn(1).setCellEditor(hoodNumberEditor);

1) Your custom cell renderer does nothing extra, so you can depend on default renderer.
2) Instead of extending JLabel and implementing TableCellReneder, you should extend DefaultTableCellRenderer and override its get renderer method because DefaultTableCellRenderer itself extends JLabel and aditionally it does some optimizations etc., which you can miss if you implement your own renderer.
3) If you set foreground and background color in last else statement also, then you can see the values correctly in windows L&F as well.
Thanks!

How do I edit a table cell value in the same view?

This is probably just a clarification more than a question, but when looking at the iPhone->Settings->Mail,Contacts,Calenders view. If you select a mail account, you are taken to the account edit view where you can edit your account information.
In this particular example, there is a 4 row grouped table section, with headers like "Name", "Address", "Password" and "Description".
I am trying to duplicate this method of data entry where I don't have the user select the cell and get navigated to a new screen, but rather just pop up the appropriate keyboard, and allow them to edit within the cells within the same view.
Currently, the only implementation that seems to make sense is to add a UITextField to the cell, and when the user selects, it will allow them to duplicate this behavior. It seems like there's an easier way to do this, but just not finding it.
it seems like SetEditing deals more with deleting, adding and reordering...not actually editing data within the cells.
Anyways, if there are any tips/tutorials/etc to look at, much appreciated!

i do that. but the new window doesnt open a folder in the same path location
