Is there a way that i can highlight or colour various table rows based on data entered in textfield?

What i’m trying to do it’s highlight the serial number that i scan from a box of items.

So when i scan the S/N. My idea is that the table, which contains the items in the box, change their color. My english sucks, so i think images can explain my idea in a better way.

So my code does the following:

First i load the table with the info from the box 1 (“Gaveta”):

Then when i filter the S/N of the item in the box:

i face my problem, the search paints the correct S/N but it damages my tablemodel.

My code:

Data search:

public void buscarNumeroSerie (String nserie) { try {

             String [] campos={"NUMERO_SERIE","MARCA","GAVETA"};
             String filtroNS = nserie;
             String NSSQL = "SELECT NUMERO_SERIE,MARCA,GAVETA FROM"
                     + "(SELECT NUMERO_SERIE,MARCA,GAVETA FROM discos_wd "
                     + "UNION "
                     + "SELECT NUMERO_SERIE,MARCA,GAVETA FROM discos_toshiba "
                     + "UNION "
                     + "SELECT NUMERO_SERIE,MARCA,GAVETA FROM discos_seagate "
                     + "UNION "
                     + "SELECT NUMERO_SERIE,MARCA,GAVETA FROM discos_samsung "
                     + "UNION "
                     + "SELECT NUMERO_SERIE,MARCA,GAVETA FROM discos_hitachi )"
                     + "AS TROUBLE WHERE NUMERO_SERIE LIKE '%"+filtroNS+"%'";

            System.out.println(NSSQL); 
                    nsconn = metodosPool.dataSource.getConnection();
                    //ModeloTablaLista = new DefaultTableModel(null, campos);
                    stmnt = nsconn.prepareStatement(NSSQL);
                    ResultSet nsrs = stmnt.executeQuery(NSSQL);

            //if(nsrs.next()== true){

Table Renderer:

public ClaseColor(int patron) {

}

@Override
public Component getTableCellRendererComponent
           (JTable tablaDiscosGaveta, 
            Object value, 
            boolean Selected, 
            boolean hasFocus, 
            int row, 
            int col) 
    {

    if (!tfNumeroSeriePurga.getText().equals(tablaDiscosGaveta.getValueAt(row, patron).toString())) 

    {
        System.out.println("FramePurgar.PurgarDiscos1.ClaseColor.methodName()"+"no pille nada !");
    } 
   else
    {
        setForeground(Color.RED);
        //setFont(font);
        //
        super.getTableCellRendererComponent(tablaDiscosGaveta, value, Selected, hasFocus, row, col);
        return this;
    }

return this;

} }

What i’m trying to do is paint every S/N that matchs with the textField “Serial Number” which does the search.

Something like this:

http://prntscr.com/o4ynui

so any new S/N i search, get a mark while i keep scanning S/N, and then the S/N that are not marked, are eliminated from the table.

Answer

Final update at this, i fixed my problem changing the value at the following line:

   Component comp = super.getTableCellRendererComponent(tablaDiscosGaveta, col, rootPaneCheckingEnabled, rootPaneCheckingEnabled, row, col);

for

        Component comp = super.getTableCellRendererComponent(tablaDiscosGaveta, value, rootPaneCheckingEnabled, rootPaneCheckingEnabled, row, col);

Finally !
