Guide to set the cell background color and foreground color

hi all,
I am using a tool called POI for excel from java. IF any body know POI please tell me the various colors --------> equivalent Short number. I need the color and equavlent number for better usage.
please respond as early as possible.

Hi
Use the class HSSFColor at org.apache.poi.hssf.util and the inner classes defined, for example (sample form jakarta.poi):
style.setFillForegroundColor(HSSFColor.ORANGE.index);
or for a cell
cell.setFillForegroundColor(HSSFColor.ORANGE.index);
If you need know what index for a color may be at source code you can see the implementation.
Hope this helps

Setting the Border background color

Post Author: gravy
CA Forum: .NET
Hi,
Using the API I'm trying to set the Border background color to transparent but I can't. I want to set the background color to match what the designer does when you uncheck the Background option on the Border tab of a TextObjects properties.
Can anyone help?

Setting the TabbedPane background color

Hello everyone,
The following code does not set the tabbedpane's background color:
class LIB
public static void main (String ... args)
javax.swing.JTabbedPane t=new javax.swing.JTabbedPane();
t.setOpaque(true);
t.setBackground(java.awt.Color.RED);
t.setForeground(java.awt.Color.GREEN);

t.setTitleAt(0,"Tab 1");
javax.swing.JFrame f=new javax.swing.JFrame();
f.getContentPane().add(t);
f.pack();
f.setVisible(true);
}What is wrong with thid code ??
Thank you

You had an answer with in the first 10 minutes. And your post was on one of the three most popular forums.10 minutes, that is true. But then I sent a reply on Dec 6, 11:43 AM and did not get an answer until Dec 8, 5:44 AM (that is after I had already posted the same problem on another forum).
Also, if you ever do need to post the same question on another forum at least put a link between the two.Since I am new to the forum, I don't know how to do that. Would you be kind enough to tell me how.
Thank you

Set cell background color conditionally?

I want to set a cells' background colors conditionally, e.g., if the computer value is between 5 to 9, make the background red. Is there any way to do that?

That is a good question. It would appear it does not work. A way around it is to put 1:00 (1 hour duration, not 1 o'clock) in a cell and a 1:30 in another then reference those cells as your two conditions.
This is not the only place where the duration format is not fully implemented.

Set current row background color

during post-query process, if record meets condition,
i would like to set the color of entire line.
thank you

Hi Jim,
create a visual_attribute named e.g. PQR and set the desired background color.
In post-query trigger:
declare
     currec number := Get_block_property('block1', current_record);
begin
if "condition" then
     set_item_instance_property('item1',     currec,visual_attribute,'PQR');
     set_item_instance_property('item2',     currec,visual_attribute,'PQR');
     set_item_instance_property('item3',     currec,visual_attribute,'PQR');
end if;
end;
Good luck,

Is it possible to apply conditional formatting to a cell (or range) based upon a LOOKUP query to cell values in another sheet.? I want to alter the formatting (i.e., text and/or cell background color), but not cell content.

Is it possible to apply conditional formatting to a cell (or range) based upon a LOOKUP query to cell values in another sheet.?
I want to alter the formatting (i.e., text and/or cell background color), but not the content, of the target cell(s).

Hi Tom,
Your LOOKUP formula will return a value that it finds in the "other" table. That value can be used in conditional highlighting rules. (Numbers 3 calls it conditional highlighting, not conditional formatting. Just to keep us awake, I guess, but it works the same).
Please explain what you are trying to do.

Ian.

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.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.

Cell background colors are not showing in preview - help? - DW4

Hi,
I created a horizontal table for my menu bar, and gave each cell a different color by creating a separate class for each with background image - image is a block of color created in Photoshop. In design mode they look they way I want, but in preview (Safari) the colors don't show up at all - the whole area is gray, and all I see is the text for each cell. Can someone tell me what I'm doing wrong? Alternatively, is there a better way I can set this up to have different colors for each button?
Thank you!

Here is the HTML code, and the CSS code for the menu bar follows:
     ul.MenuBarHorizontal

JTable cell background color

Hi All,
I want to change the background color of the same of the cells in jTabel. How can I do that.
Like, I want to keep 3 cells in red color. Another 2 cells in in green color, And keep other cell background color to default.
Also I want to change the background color of the cell, with different selection in other component(like jTree, jList).
Thank you,
Avin Patel

The same cell renderer is used by all cells of the table. You can't just set the background color of a cell once. You have to reset it every time the cell renderer is called (depending on which row/column you are being asked to render). Here is an example:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableCell extends JFrame
     JTable table;
     public TableCell()
          Object[][] data = { {"1", "A"}, {"2", "B"}, {"3", "C"}, {"4", "D"} };
          String[] columnNames = {"Number","Letter"};
          DefaultTableModel model = new DefaultTableModel(data, columnNames);
          table = new JTable( model );
          // Set default cell renderer
          TableCellRenderer renderer = new TestRenderer();
          table.setDefaultRenderer(Object.class, renderer);
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
     public static void main(String[] args)
          TableCell frame = new TableCell();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
     class TestRenderer extends DefaultTableCellRenderer
          public Component getTableCellRendererComponent(
               JTable table,
               Object value,
               boolean isSelected,
               boolean hasFocus,
               int row,
               int column)
               super.getTableCellRendererComponent(table,
               value, isSelected, hasFocus, row, column);
               if (column == 0)
                    setHorizontalAlignment( LEFT );
                    setBackground( Color.blue );
               else
                    setHorizontalAlignment( RIGHT );
                    setBackground( Color.green );
               if (row == 1)
                    setBackground( Color.red );
               return this;

Calendar Activity instance using calendar cell background color

Hi ,
We have a requirement to show activity instance belong to a certain provider in calendar using the calendar cell background color, instead of the color of activity. Is this possible? If so, how to implement it?
I checked the calendar skin keys here:
http://jdevadf.oracle.com/adf-richclient-demo/faces/components/skinningKeys/calendar.jspx
but only find some keys related to activity like "af|calendar::month-time-activity", "af|calendar::all-day-activity" and "af|calendar::month-time-activity". These highlight the activity with color, but not the whole calendar cell.
I saw there is a skin key called "af|calendar::month-grid-cell" which set the background color of the calendar cells for the month. This is similar to what I am looking for, but I would like the cell's background color for the cells of the activity instance only, not all the cells in the month.
Any ideas?
Thanks
-Mina

Hi Mina,
There is a way to highlight cells corresponding to activity by using skinning, but you have to set the backgroud color property: af|calendar::month-time-activity{ background-color: Blue; }

How do I change the tab background color in Firefox 4?

I just upgraded to Firefox 4. Tabs are now fine black font on dark grey background -- very hard to read. How do I change the tab background color?
I have searched and the closest I can come is some instructions for modifying .css files, and it is not clear that those instructions will impact the tab background color.
Thanks in advance for your help.

Similar question asked by TH received another response.
Here is the address of that question and answer:
https://support.mozilla.com/en-US/questions/804464?s=change+tab+color+firefox+4&as=s
I like the solution recommended there.
Added information - after several days experience, I notice that some tabs occasionally revert to the original dark grey. So I am still looking for a better solution, ideally within Firefox rather than via add on. This seems like a basic setting for the browser that should be easy to change, rather than something so complex that I need an add on to change it. Or just build it without such a dark grey background to begin with and I would not need to change it.

How to change a selected cell background color in JTable?

Hi all,
I am trying to change the background color of a selected cell by clicking on that particular cell. DefaultTableCellRenderer class provides setBackground(Color c) to change the background color of unselected cells. Is there a way to change a selected cell background color?
Thank you,
Arthur

Write your own renderer (eg. extending DefaultTableRenderer) and put in getTableCellRendererComponent method something like this:
if( isSelected && hasFocus )
setBackground( Color.RED );
setForeground( Color.GREEN );
}

Setting a default background color

Hi All,
I would like to set a default background color for all the
components that I'm going to draw. What is the best
way to achieve this?
Thanks.
Syed

You can set using UIManager of the Look and Feel.
UIManger.put("Button.background", Color.blue);
will set the color of all the JButtons to blue. Like that you can change for all the components you need.
