Hi friends,
I need to give different foreground color for the same cell in a JTable?
I used the TableCellRenderer to give different color for different rows of a JTable by checking the value of the data in each cell.
Is there any way to give different foreground color for a single cell in a JTable.

Thanks In Advance......

Looks like I have solved similar problem.

My point was to dash cell background with diagonal lines under the cell value so everything is displayed in cell as usual,
but over diagonal dashes.

The solution was to implement proxy renderer which inherits from JPanel. It contains any custom
renderer as subcomponent of panel.
Before display placed component is switched to invisible,
the panel rendered,
the any other staff rendered over empty panel,
the component switched to visible and rendered with property opaque=false.

Please consider sources for details.

Doesn't TableCellRenderer's getTableCellRendererComponent both a row and column parameter? In other words, you know the exact cell.

Thanks Rob,
I really appreciate your time and help.

Yes, I know the exact cell.

This is the TableCellRenderer class I am using

class CustomTableCellRenderer extends DefaultTableCellRenderer {

protected static Border noFocusBorder = new EmptyBorder(0, 0, 0, 0);

public CustomTableCellRenderer() {
super();
setOpaque(true);
setBorder(noFocusBorder);
}
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);
Object columnValue = table.getValueAt(row, 1);
String columnValue1 = columnValue.toString();
columnValue1 = columnValue1.trim();
Object columnValue2 = table.getValueAt(row, 0);
String columnValue3 = columnValue2.toString();
columnValue3 = columnValue3.toString();

if (isSelected) {
setBackground(table.getSelectionBackground());
setForeground(table.getSelectionForeground());
} else if (columnValue1.equals("In:")) {
if (columnValue3.indexOf("Error") != -1) {
setBackground(Color.GREEN);
setForeground(Color.WHITE);
} else {
setBackground(Color.WHITE);
setForeground(Color.GREEN);
}
} else if (columnValue1.equals("Out:")) {

if (columnValue3.indexOf("Error") != -1) {
setBackground(Color.RED);
setForeground(Color.WHITE);
} else {
setBackground(Color.WHITE);
setForeground(Color.RED);
}
}
return cell;
}
}





In a cell, I have a string value like ("Red Yellow"). I need to display the first part of the value (Red) in red color (foreground) and the second part of the value(Yellow) in yellow color(foreground).

Rob, thanks in advance.............

Thanks....

Please http://faq.javaranch.com/java/UseCodeTags


As for the answer, you'll need to parse your value into two substrings, then convert each into a Color object (using a lookup or something).

It's even simpler to solve your problem, try HTML for your values:

<html><span bgcolor="blue">Blue</span> Normal <span bgcolor="red">Red</span>

Thanks Rob,

I can parse the string into two substring and after that how can I convert that into Color object.
I don't know how to use lookup.
Rob, please send me some links or some hints about how to use lookup, if you have time,

Thanks in advance....

Thanks..

Hi Dmitry,

Thanks for your time.

I tried the code .



But it is displaying the characters in black color....

I don't know, what is the problem with this.

Is there any other way to do this coloring.


Thanks

Hi Renjith.

My example explains how to configure text background color,
to change foreground you may use tag <font> like:

<html><span bgcolor="blue"><font color="red">Red on blue</font><span>

A map comes into mind:
I've used a TreeMap with String.CASE_INSENSITIVE_ORDER so the case of the strings does not matter. Therefore, COLORS.get("red") COLORS.get("RED") and COLORS.get("Red") all return Color.red.
