I have JTable which first column is editable as a checkbox. It works correct for single row selection, but I don't have any idea what should I do if I want to check more than one row. There is my class which implements TableCellRenderer:
private class MyTableRenderer extends JCheckBox implements TableCellRenderer{
private int row;
public MyTableRenderer() {
}
@Override
public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus, int row, int col) {
if(isSelected) {
this.row = table.getSelectedRow();
if(isSelected()) setSelected(false);
else setSelected(true);
}
return this;
}
}
and there is a part of class which extends AbstractTableModel:
private class CompanyTable extends AbstractTableModel {
//...
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
if(columnIndex==0) {
MyTableRenderer renderer = new MyTableRenderer();
TableColumn tableColumn = new TableColumn();
tableColumn = table.getColumnModel().getColumn(0);
tableColumn.setCellRenderer(renderer);
return null;
}
if(columnIndex==1)
//...
else
//...
}
@Override
public String getColumnName(int column) {
// TODO Auto-generated method stub
return columnsName[column];
}
@Override
public Class<?> getColumnClass(int columnIndex) {
return super.getColumnClass(columnIndex);
}
@Override
public boolean isCellEditable(int rowIndex, int columnIndex) {
if(columnIndex == 0) return true;
return false;
}
Do you have any idea what should I do?
