This change require this other change
Inside the class ThemeTable you must change the configuration from this code
UIManager.put("Table.alternateRowColor", this.isAlternaterowcolor());
UIManager.put("Table.alternateRowBackground", this.getAlternaterowbackground());
to this code
UIManager.put("Table.alternateRowColor", this.getAlternaterowbackground());
Why? You can find the answer to the your question here
To correct work of this JTable configuration style, you should did this change
Now if you did all passage correclty you should be see the correct effect, inside the table with layer KRC.
The Swing L&F Work witht the ResurcesUI instances, you can find motivation here
The method getAlternaterowbackground() should return the ColorUIResources and not an Color because the Color is ignorate to Swing.
You can use the following code inside ThemeProvaider
public static Color parse(String input) {
Pattern c = Pattern.compile("rgb *\\( *([0-9]+), *([0-9]+), *([0-9]+) *\\)");
Matcher m = c.matcher(input);
if (m.matches())
{
return new ColorUIResource(Integer.valueOf(m.group(1)), // r
Integer.valueOf(m.group(2)), // g
Integer.valueOf(m.group(3))); // b
}
return null;
}
Before this reafctoring the CraterTable used a personal renderer but shoult be instancent the new DefaultTableCellRenderer and not the TableCellRenderer because this last, is an interface and you shourd be implement all swing logic that is contains inside the DefaultTableCellRenderer
The new code is
TableCellRenderer diameterRenderer = new DefaultTableCellRenderer() {
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (value instanceof String) {
setText(""+value);
}else{
double val = (Double)value;
if (val>500) {
setText(diamterFormatter.format(val / 1000.0) + " km");
} else {
setText(diamterFormatter.format(val) + " m");
}
}
return this;
}
};
Also, this the previus code you can lose some L&F personalizzations, like the text centered.
So for material library you shoul be create a new MaterialTableCellRenderer, but for refactoring the JMars code only one time, you should create a JMarsTableCellRenderer (This is a Template pattern), the code of the class is very, very basic
package edu.asu.jmars.ui.jmarscomponent;
import mdlaf.components.table.MaterialTableCellRenderer;
import javax.swing.*;
import java.awt.*;
public class JMarsTableCellRenderer extends MaterialTableCellRenderer {
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
//Insert here some common personalizing.
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
return this;
}
}
Now the final code of CraterTableCellRendere is the following:
TableCellRenderer diameterRenderer = new JMarsTableCellRenderer(){
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
if (value instanceof String) {
setText(""+value);
}else{
double val = (Double)value;
if (val>500) {
setText(diamterFormatter.format(val / 1000.0) + " km");
} else {
setText(diamterFormatter.format(val) + " m");
}
}
return this;
}
};
Why? because inside the Crater TableCellRendere you can call the super and you should be add the common personalizzation inside the JMarsTableCellRenderer without refactoring in all classes. It is cool, right? 😄
