JTable: Zelleninhalt fett schreiben

Lädde

Grünschnabel
Hallo!

Ich verwende den TableSorter, mit dem ich meine Tabelle nach der Spalte, auf die geklickt worden ist, sortieren kann.
Jetzt würde ich gerne die Inhalte in der Spalte, nach der sortiert wurde, fett schreiben.

Kann man in einzelnen Zellen die Schriftart ändern?
Hat mir da jemand einen Tipp?
 
Moin,
geht mit einem eigenen TableCellRenderer in der Methode getTableCellRendererComponent().
Beispiele dazu gibt es hier im Forum genügend.

Danke, dein Programm läuft echt gut.
Leider will´s bei mir nicht richtig.
Ich hab mir den Teil herausgenommen:
Code:
jTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {
            public Component getTableCellRendererComponent(JTable table,
                    Object value, boolean isSelected, boolean hasFocus,
                    int row, int column) {
                Component component = super.getTableCellRendererComponent(
                        table, value, isSelected, hasFocus, row, column);
                if (column == getColumn()) {
                    component.setFont(component.getFont().deriveFont(Font.BOLD));
                }
                return component;
            }
        });
Irgendwie fängt bei mir die column erst bei 1 an zu zählen. D.h. meine erste Spalte wird nie fett.
Woran könnte das liegen?

Und meine nächste Frage wäre dann:
Wie bekomm ich den Spaltenkopf auch noch fett geschrieben?

Gruß, Lädde
 
Hallo!

*räusper*
Code:
 public void sortByColumn(final int clm) {
 			 if (clm == 0) { // erste Spalte nicht Sortieren...
 				 return;
 			 }

Hi!

Das ist nicht das Problem.
Den Teil hab ich gar nicht benutzt.
Ich sortiere damit:
Code:
package xdki;

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.util.List;

import javax.swing.*;
import javax.swing.event.TableModelEvent;
import javax.swing.event.TableModelListener;
import javax.swing.table.*;

/**
 * TableSorter is a decorator for TableModels; adding sorting
 * functionality to a supplied TableModel. TableSorter does
 * not store or copy the data in its TableModel; instead it maintains
 * a map from the row indexes of the view to the row indexes of the
 * model. As requests are made of the sorter (like getValueAt(row, col))
 * they are passed to the underlying model after the row numbers
 * have been translated via the internal mapping array. This way,
 * the TableSorter appears to hold another copy of the table
 * with the rows in a different order.
 * <p/>
 * TableSorter registers itself as a listener to the underlying model,
 * just as the JTable itself would. Events recieved from the model
 * are examined, sometimes manipulated (typically widened), and then
 * passed on to the TableSorter's listeners (typically the JTable).
 * If a change to the model has invalidated the order of TableSorter's
 * rows, a note of this is made and the sorter will resort the
 * rows the next time a value is requested.
 * <p/>
 * When the tableHeader property is set, either by using the
 * setTableHeader() method or the two argument constructor, the
 * table header may be used as a complete UI for TableSorter.
 * The default renderer of the tableHeader is decorated with a renderer
 * that indicates the sorting status of each column. In addition,
 * a mouse listener is installed with the following behavior:
 * <ul>
 * <li>
 * Mouse-click: Clears the sorting status of all other columns
 * and advances the sorting status of that column through three
 * values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to
 * NOT_SORTED again).
 * <li>
 * SHIFT-mouse-click: Clears the sorting status of all other columns
 * and cycles the sorting status of the column through the same
 * three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
 * <li>
 * CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except
 * that the changes to the column do not cancel the statuses of columns
 * that are already sorting - giving a way to initiate a compound
 * sort.
 * </ul>
 * <p/>
 * This is a long overdue rewrite of a class of the same name that
 * first appeared in the swing table demos in 1997.

Wieso der Renderer die columns bei 1 anfängt zu zählen, hab ich leider noch nicht gefunden.

Hast Du für die erste Spalte einen anderen Renderer gesetzt? Oder eine andere Class für diese TableColumn?
 
Nicht, dass ich wüsste.
Vom Renderer hab ich erst bei dem Problem hier was gehört.

Meine Tabelle befüll ich so:
Code:
package xdki;

import javax.swing.*;
import javax.swing.table.*;
import java.util.*;

public class MyTableModel extends AbstractTableModel {
    private String[] columnNames = {"Part no.", "Type", "Article designation", "Product name", "Price in €", "PC"};
    private Object[][] data;
        
    public MyTableModel(Vector v){
        this.data = new Object[v.size()][6];
        for(int i = 0; i < v.size(); i++){
            Produkt produkt = (Produkt)v.get(i);
            data[i][0] = produkt.getPartno();
            data[i][1] = produkt.getType();
            data[i][2] = produkt.getBnn();
            data[i][3] = produkt.getVn();
            data[i][4] = produkt.getTrz();
            data[i][5] = produkt.getTrw();
        }
    }
    
    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.
        return false;
    }
    
        /*
         * Don't need to implement this method unless your table's
         * data can change.
         */
    public void setValueAt(Object value, int row, int col) {
        
        
        data[row][col] = value;
        fireTableCellUpdated(row, col);
        
        
    }
    
    
}
Meine Daten kommen aus einer DB und werden mit dem Vektor v übergeben.
 
Lädde hat gesagt.:
Code:
jTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {
            public Component getTableCellRendererComponent(JTable table,
                    Object value, boolean isSelected, boolean hasFocus,
                    int row, int column) {
                Component component = super.getTableCellRendererComponent(
                        table, value, isSelected, hasFocus, row, column);
                if (column == getColumn()) {
                    component.setFont(component.getFont().deriveFont(Font.BOLD));
                }
                return component;
            }
        });
Irgendwie fängt bei mir die column erst bei 1 an zu zählen. D.h. meine erste Spalte wird nie fett.
Woran könnte das liegen?

Gruß, Lädde

Also offenbar ist ja
if (column == getColumn()) {
von Bedeutung. Hast Du geprüft, ob column jemals 0 ist? Wenn ja, liefert getColumn() evtl. eine Abweichung? Wenn nein, wird der Renderer definitiv nicht für die erste Spalte benutzt. Dann musst Du herausfinden, weshalb. Die Renderer-Zuweisung ist ein Zusammenspiel zwischen getColumnClass und setDefaultRenderer(Klasse, zu verwendender Renderer)
 
Nein, column wird niemals 0.
getColumn() dagegen liefert mir, nach welcher Spalte sortiert wurde und ist dann 0.

Danke für die Erklärung.
Jetzt weiß ich, wo ich anfangen kann zu suchen.
