I am using this code to accept only numbers in the jtable cell, but I would like to know how to accept .
as well. Can someone help me?
I'm using java language on the netbeans platform.
TableColumn col = tabela.getColumnModel().getColumn(1);
col.setCellEditor(new MyTableCellEditor());
class MyTableCellEditor extends AbstractCellEditor
implements TableCellEditor{
JComponent component = new JTextField();
public boolean stopCellEditing(){
String s = (String)getCellEditorValue();
boolean valido = true;
for(int i = 0; i < s.length(); i++){
Character caractere = s.charAt(i);
if(!Character.isDigit(caractere)){
valido = false;
break;
}
}
if(!valido){
JOptionPane.showMessageDialog(null,
"Valor inválido");
return false;
}
return super.stopCellEditing();
}
public Component getTableCellEditorComponent(
JTable table, Object value,
boolean isSelected, int rowIndex, int vColIndex){
if(isSelected){
//
}
((JTextField)component).setText((String)value);
return component;
}
public Object getCellEditorValue() {
return ((JTextField)component).getText();
}
}
