Coloring entire row ??? (TableColumn) (cell rendering)

Hi,
I know this question has been posted a few times but i just couldn't make it work.. i have attached my app below. the idea is to paint the whole row to red if value[row,0] = '*' but the problem here is that only that particular row and column i.e. aRow and aColumn indicated in the cell renderer class is painted red .. i want the whole row to be red not only that particular column and row.. i can get the aRow and aTable from the renderer class but can't figure out how to use these values to paint the whole row for the table RegLocationsTableModel2...... please shed some lights on this.....
loadhandler.java
=============
int vcolIndex=0; //for checking '*' value
TableColumn col = screen.regLocationsTable.getColumnModel().getColumn(vColIndex);
col.setCellRenderer(new RenderRedGreen());
( (RegLocationsTableModel2) screen.regLocationsTable.getModel()).
addPartnerProRecord(partner);
( (RegLocationsTableModel2) screen.regLocationsTable.getModel()).
fireTableDataChanged();
cell renderer class:
===============
final class RenderRedGreen extends DefaultTableCellRenderer {
RenderRedGreen () {
setHorizontalAlignment(SwingConstants.RIGHT);
public Component getTableCellRendererComponent(JTable aTable,
Object aNumberValue,
boolean aIsSelected,
boolean aHasFocus,
int aRow, int aColumn) {
if (aNumberValue == null) return this;
Component renderer = super.getTableCellRendererComponent(aTable,
aNumberValue,
aIsSelected,
aHasFocus,
aRow, aColumn);
System.out.println("RenderRedGreen.java::aTable=" + aTable);
System.out.println("RenderRedGreen.java::aRow=" + aRow); // how to use these values????
if (aNumberValue.equals("*"))
System.out.println("RenderRedGreen.java::aNumberValu is *=");
renderer.setBackground(Color.red);
else {
renderer.setBackground(Color.white);
return this;
thanx very much....
tamoooo

even after changing that if(..) statement, only the first column/cell of the row that has '*' value is coloured to red... other columns of the row basically remains as white..
as far as i understand correctly the cell rendering, in my case, the loadhandler.java calls the cell renderer class (RenderRedGreen.java) with vColIndex=0... i.e. checking the 0th column of the row.. if the value of the first cell is '*' then the background OF THE CELL is set to red otherwise the background of the cell is set to white.. and all the while, the check is only been done on the 0th column of each row... so basically no coloring will be done on the other rows.. (???)
i think that somehow since aRow of aTable indicates the row for whose the 0th column is '*' and is the row whose entire column is to be colored.. somehow it has to be rendered from within the render class (RenderRedGreen.java).. any suggestions??? i think some of us has already done entire row coloring.. need some insight into this..

Custom table model, table sorter, and cell renderer to use hidden columns

Hello,
I'm having a hard time figuring out the best way to go about this. I currently have a JTable with an custom table model to make the cells immutable. Furthermore, I have a "hidden" column in the table model so that I can access the items selected from a database by their recid, and then another hidden column that keeps track of the appropriate color for a custom cell renderer.
Subject -- Sender -- Date hidden rec id color
Hello Pete Jan 15, 2003 2900 blue
Basically, when a row is selected, it grabs the record id from the hidden column. This essentially allows me to have a data[][] object independent of the one that is used to display the JTable. Instinctively, this does not seem right, but I don't know how else to do it. I know that the DefaultTableModel uses a Vector even when it's constructed with an array and I've read elsewhere that it's not a good idea to do what I'm trying to do.
The other complication is that I have a table sorter as well. So, when it sorts the objects in the table, I have it recreate the data array and then set the data array of the ImmutableTableModel when it has rearranged all of the items in the array.
On top of this, I have a custom cell renderer as well. This checks yet another hidden field and displays the row accordingly. So, not only does the table sort need to inform the table model of a change in the data structure, but also the cell renderer.
Is there a better way to keep the data in sync between all of these?

To the OP, having hidden columns is just fine, I do that all the time.. Nothing says you have to display ALL the info you have..
Now, the column appears to be sorting properly
whenever a new row is added. However, when I attempt
to remove the selected row, it now removes a seemingly
random row and I am left with an unselectable blank
line in my JTable.I have a class that uses an int[] to index the data.. The table model displays rows in order of the index, not the actual order of the data (in my case a Vector of Object[]'s).. Saves a lotta work when sorting..
If you're using a similar indexing scheme: If you're deleting a row, you have to delete the data in the vector at the INDEX table.getSelectedRow(), not the actual data contained at
vector.elementAt(table.getSelectedRow()). This would account for a seemingly 'random' row getting deleted, instead of the row you intend.
Because the row is unselectable, it sounds like you have a null in your model where you should have a row of data.. When you do
vector.removeElementAt(int), the Vector class packs itself. An array does not. If you have an array, when you delete the row you must make sure you dont have that gap.. Make a new array of
(old array length-1), populate it, and give it back to your model.. Using Vectors makes this automatic.
Also, you must make sure your model knows the data changed:
model.fireTableDataChanged(); otherwise it has no idea anything happened..
IDK if that's how you're doing it, but it sounds remarkably similar to what I went thru when I put all this together..

How do you set the font color for a specific entire row inside a JTable?

How do you set the font color for a specific entire row inside a JTable?
I want to change the font color for only a couple of rows inside a JTable.
I've seen some ways to possibly do this with an individual cell.
Clarification on changing the font color in an individual cell would be helpful too if
there is no easy way to do this for a row.

hai,
Try out with this piece of code.Create your table and assign the renderer to each column in the table.
CellColorRenderer m_CellColorRenderer = new CellColorRenderer();
for(int i=0;i<your_JTable.getColumnCount();i++)
your_JTable.getColumnModel().getColumn(i).setCellRenderer(m_CellColorRenderer);
class CellColorRenderer extends JLabel implements TableCellRenderer
CellColorRenderer()
setOpaque(true);
setHorizontalAlignment(LEFT);
setVerticalAlignment(CENTER);
setBackground(Color.white);
setForeground(Color.black);
protected void setValue(Object value)
     setText((value == null) ? "" : value.toString());
public Component getTableCellRendererComponent(JTable table,Object value,boolean isSelected, boolean hasFocus, int row,int column)
     if(isSelected == true)
          setForeground(Color.red);
     else
          setForeground(Color.black);
     setValue(value);
     return this;

Jtable: How to change the color of an entire row?

How can I change the color on an entire row in a Jtable based upon the value in one of the cells in that row.
For example: Lets say:
I have 5 rows. Each row has 4 columns.
If column 4 has a value "A" in any of the rows, all the text in that row should be red.
If column 4 has a value "B" in any of the rows, all the text in that row should be blue.
Just point me in the right direction and I will try to take it on from there.
Thanks

In the future, Swing related questions should be posted in the Swing forum.
But there is no need to repost because you can search the Swing forum for my "Table Prepare Renderer" (without the spaces) example which shows how this can be done.
But first read the tutorial link given above.

JTree cell renderer: how to fill whole row?

hi,
i'm trying to make a tree cell renderer that renders at default height, but fills the horizontal width of the tree (e.g. with a JLabel with a custom background color). I'm working on the theory that in order to do this you need to change the preferred size of the component used to stamp the image at render time.
The problem is that the preferred width then needs to be set to a value that depends on the context of the particular node (e.g. a deeply nested child node will be further to the right than the root node).
I can't seem to find a method to say where the rendering starts though - does anyone know a way?
(also if not then would setting the width to some astronimcal value break anything?)
thanks,
asjf

Try this one, it will higlight the background and foreground colors of entire rows.

How to change the semantic color of entire rows in a table.

Hi, in the past I already managed to change the semantic color of a cell by a condition (for example all the cells with negative number -> I set negative semantic color)
My question is how can I change the semantic color of the entire row where this cell belong, and not only the cell. Im using NW2004.
BTW, Im not a java programmer, neither a Webdynpro expert, just an ABAP Programmer. So try to be very explicit, Thx.

Rodrigo,
You can just bind correspondign property of every cell editor (TextView) of every column to the very same context attribute. Next, when you change attribute value for certain elemnt, the whole row (every cell editor in row) will get same value.

Hi,
I have created a custom cell renderer to set color in my table based on some value and the screen also shows colors when i set this cell renderer.
But, I am not able to see the row selection ie. with blue background when I select any row in the table is nor appearing. Can you tell me how to solve this problem.

Right way to change datagrid row, column, cells background colors in code-behind?

Hi all,
I have a winform program that I'm upgrading to wpf (I'm new to wpf). The wpf code for the function (SetdataGridBackgroundColors()) is below with the winform code commented out so I can fix it. I have a datagrid with a Cornsilk background color alteranating
with LightGreen depending on the content of datetime cell. If the day portion of the datetime is different then the color changes from one to the other. I used a colorIndex variable because at the end of the month it could go from 31 to 1 and that would
not work if I use the day directly.
I tried this line to change the background color:
optionsDataDatagrid.RowBackground = new SolidColorBrush(Colors.Cornsilk);
this works but it changes every row. I found this other stuff:
DataGridRow currentRowColor = optionsDataDatagrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
//DataGridRow currentRowColor = optionsDataDatagrid.ItemContainerGenerator.ContainerFromItem(optionsDataDatagrid.Items[i]) as DataGridRow;
currentRowColor.Background = new SolidColorBrush(Colors.Cornsilk);
Either ContainerFromIndex or ContainerFromItem throw an exception because currentRowColor is null. I looked at optionsDataDatagrid.Items[i] and is not null. Then I read that using ItemContainerGenerator is not a good idea.
BTW I'm calling SetdataGridBackgroundColors() after datagrid is been filled with data.
So... what is the proper way to set each row, column or cell background color in wpf?
Thanks
private void SetdataGridBackgroundColors()
optionRowData rowData = new optionRowData();
if (optionsDataDatagrid.Items.Count == 0)
return;
int colorIndex = 1;
DateTime savedDate, currentRowDate;
rowData = optionsDataDatagrid.Items[0] as optionRowData;
savedDate = rowData.col_datetime.Date; //only compare the date not the time
for (int i = 0; i < optionsDataDatagrid.Items.Count; i++)
//currentRowDate = Convert.ToDateTime(optionsDataDatagrid.Rows[i].Cells[3].Value); //winform code
//currentRowDate = currentRowDate.Date; //winform code
rowData = optionsDataDatagrid.Items[i] as optionRowData;
currentRowDate = rowData.col_datetime.Date;
if (currentRowDate != savedDate)
colorIndex++;
savedDate = currentRowDate;
if (colorIndex % 2 == 0)
//optionsDataDatagrid.Rows[i].DefaultCellStyle.BackColor = Color.Cornsilk;
//------------------- testing new code --------------begin
optionsDataDatagrid.RowBackground = new SolidColorBrush(Colors.Cornsilk); //this changes all rows
//DataGridRow currentRowColor = optionsDataDatagrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
//DataGridRow currentRowColor = optionsDataDatagrid.ItemContainerGenerator.ContainerFromItem(optionsDataDatagrid.Items[i]) as DataGridRow;
//currentRowColor.Background = new SolidColorBrush(Colors.Cornsilk);
//------------------- testing new code --------------end
//optionsDataDatagrid.Columns[4].DefaultCellStyle.BackColor = Color.DarkSalmon;
//optionsDataDatagrid.Columns[5].DefaultCellStyle.BackColor = Color.Aquamarine;
//optionsDataDatagrid.Rows[i].Cells[4].Style.ApplyStyle(optionsDataDataGridView.Columns[4].DefaultCellStyle);
//optionsDataDatagrid.Rows[i].Cells[5].Style.ApplyStyle(optionsDataDataGridView.Columns[5].DefaultCellStyle);
else
//optionsDataDatagrid.Rows[i].DefaultCellStyle.BackColor = Color.LightGreen;
//------------------- testing new code --------------begin
optionsDataDatagrid.RowBackground = new SolidColorBrush(Colors.LightGreen); //this has no effect
//------------------- testing new code --------------end
//optionsDataDatagrid.Columns[4].DefaultCellStyle.BackColor = Color.Coral;
//optionsDataDatagrid.Columns[5].DefaultCellStyle.BackColor = Color.LimeGreen;
//optionsDataDatagrid.Rows[i].Cells[4].Style.ApplyStyle(optionsDataDataGridView.Columns[4].DefaultCellStyle);
//optionsDataDatagrid.Rows[i].Cells[5].Style.ApplyStyle(optionsDataDataGridView.Columns[5].DefaultCellStyle);

I (also) strongly recommend mvvm.
Setting values is a particularly bad idea in this case.
I don't mean to be rude but your explanation of the requirement is kind of vague.
I would bind solidcolourbrushes.
Set the properties based on whatever your logic is within the viewmodel.
You can switch out what each of the brushes holds when the user clicks wherever.
So you use a highlightbrush when something or other is true.
That highlightbrush is set to a blue brush when the user clicks left and a red brush when they click right.

Set Background/Foreground color for Cell Renderer in JComboBox

Hello,
I was wondering if there is a way to change default settings for when I browse items under a JComboBox's cell renderer? I want the item's color to change (to what I set it to), when mouse enters the item. As of now, the cell's background color changes to Blue when I enter it. Is this default for JComboBox or might it have been set somewhere, that I need to look into?
Please let me know if there are ways to do this.
Thanks!

JTable: Custom cell renderer on T(row, col)

Sorry if this was posted before, but the whole Search function doesn't seem to work these days (hasn't been working for a week now). Anyways:
I know how to create custom cell renderers. My problem lies with which cells I want to apply that cell renderer to. It seems I am limited in setting a cell renderer to a whole column, which I don't want.
For instance, I'd like to apply cell renderer R1 to (0,0) but not to (1,0) and not to (3,0). Instead I want cell renderer R2 on (2,0) and (3,0).
Example of my table:
|--icon--|--filename--|--extension--|
|   R1   | file1.txt |     txt     |
|   R2   | img1.jpg |     jpg     |
|   R1   | file2.txt |     txt     |
|   R2   | img2.jpg |     jpg     |
|-----------------------------------|Is there any possibility this can be achieved? I am probably overlooking some method or class, but I don't know which. Some pointers or clues in the right directions are appreciated.
Thanks

Camickr, again you've been a great help. Works great, but a NullPointerException is being thrown and I can't find out what points to a null object.
Code is this:
    public TableCellRenderer getCellRenderer(int row, int column) {
        if (getValueAt(row, 3).equals("jpg") && column == 0) {
            return new IconCellRenderer(Klue.iconAdd);
        } else {
            return super.getCellRenderer(row, column);
    }Solution is catching the NullPointerException in this method, but I'd rather have an if statement checking for it. But what to check? Any ideas?

Setting Table Cell Renderer for a row or cell

I need to make a JTable that has the following formats:
Row 1 = number with no decimals and columns
Row 2 = number with no decimals and columns
Row 3 = percent with 4 decimals
I can use a table cell renderer to set each COLUMN as one or the other formats like this:
NumDispRenderer ndr = new NumDispRenderer();
for(int i = 1;i<dates.size();i++) {
table.getColumnModel().getColumn(i).setCellRenderer(ndr);
Where NumDispRenderer is a class as follows:
public class NumDispRenderer extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent (JTable table, Object value,boolean isSelected, boolean isFocused, int row, int column) {
Component component = super.getTableCellRendererComponent (table,value,isSelected,isFocused,row,column);
if (value != null && value instanceof Double) {
DecimalFormat df = new DecimalFormat("###,###");
String output = df.format(value);
((JLabel)component).setText(output);
((JLabel)component).setHorizontalAlignment(JLabel.RIGHT);
} else {
((JLabel)component).setText(value == null ? "" : value.toString());
return component;
This is fine for the first two rows, but the third row (which is also an instance of Double) I would like to format differently.
The tutorial and other postings have not given a solution to this problem. Any suggestions would be very appreciated.

Hi,
the method getTableCellRendererComponent() of your renderer gets the row as a parameter. So just create the label depending on that value. For 0<=row<=1 you create the label as is, and for row=2 you create another label with the Double formatted as you wish.

Change colors of entire row according to another

Just to keep you guys busy:
I have a crosstab layout and I want to change the color of the entire row according to one column, is that possible??

Hi Wendy
This is a simple one to answer because the answer is no. Coloring of individual rows of data is not one of the features that any version of Discoverer currently has. I have a copy of the newest Drake and this also does not allow this I'm afraid.

How do I sort specific cells without affecting entire rows?

In Excel I can sort specific cells ascending/descending and only what I highlight will sort.
In Numbers, when I try to do that the entire row sorts.
Is there a way to only sort the highlighted cells and not have the rest of the rows sort as well?

Here's a link (Dropbox download) to a Copy Sort Acending service, that in your menu would look similar to this:
To use it, select the cells you want to sort, just as in Excel, and make the choice from the menu.
After that, unlike Excel, click once in the first cell where you want the sorted values to start appearing (either the original range, or a different range if you want) and type command-v or option-shift-command-v to paste.
The one-time installation takes a double-click on the .workflow package and a click on 'Install'. You may also have to go to System Preferences > Security & Privacy and click 'Download anyway'. Installing simply moves the service to your Library > Services folder so that it will appear in your menu. It does nothing to the innards of your Mac, and does not run unless you specifically tell it to by choosing it from the menu or running it from within Automator. You can view the script by opening it in Automator. You can remove the service if you don't need it by holding down the option key in Finder, choosing Go from the menu and navigating to Library > Services, where you can delete it the way you would any other folder or package.

A script to apply cell style to entire rows containing a specific text

Hi,
I am using InDesign CC 2014
Does anyone know how to apply a cellstyle based on text contents found in a cell in javascript?
I need to search the document and change cell style in entire row to "cellStyle01" if the text "someText" appear in cell.
I've found similar script here in forum which apply table style, but don't know how to change it to apply cell style!
var curDoc = app.activeDocument;
var allTables = curDoc.stories.everyItem().tables.everyItem();
app.findTextPreferences = app.changeTextPreferences = null;
app.findTextPreferences.findWhat = "someText";
var allFounds = allTables.findText();
app.findTextPreferences = app.changeTextPreferences = null;
for ( var i = 0; i < allFounds.length; i++ ) {
var curFound = allFounds[i];
if ( curFound.length == 1 ) {
var curFoundParent = curFound[0].parent;
// curFoundParent.parent.appliedTableStyle = curDoc.tableStyles.itemByName( "tableStyle" );
curFoundParent.parent.appliedCellStyle = curDoc.cellStyles.itemByName("cellStyle01");
Thanks!

Entire row conditional formatting based on cell value

What is the best way to apply conditional formatting to an entire row based on the value of one of the columns on that row? For example, I just want to highlight the entire row (make it red color) if the value of one of the columns is greater than 0. The method described in the past discussions is just way to difficult to apply in real life scenarios. I think it should work without any tricks as it's just a very basic functionality of spreadsheets.

The other idea is to make a second table, which has a single column and is as wide as the first table. This second table will reference the value in the first table which indicates how to shade and is formatted with conditional formatting. The second table is slid behind the first, AND the first is made transparent.
- Bottom table refers to original (top) table
bottom table contains conditional formatting as:
Now make the original table transparent by selecting the table and changing the background fill to none.
Now send the second table to the back by selecting the table then the menu item "Arrange > Send to Back"
Now slide the second table under the original
