Guten Tag,
ich versuche aus meiner ArrayList ein Wert löschen leider klappt dies nicht wie ich will
Probiere das grade so:
[code=Java]
public class test TableModel extends AbstractTableModel {
Object[][] objects = new Object[1][3];
private StammdatenDelegate delegate = StammdatenDelegate.getInstance();
ArrayList<test > list = new ArrayList<test>();
int COL_POS_NAME=0;
int COL_POS_AKTIV=1;
int COL_POS_SORT=2;
int row=0;
public void holeDaten(){
list = (ArrayList<test >) delegate.suchenallertests();
for(test entity:list){
addRow(entity, row);
row++;
}
}
private Object[][] data = new Object[][]{};
public String getColumnName(int pos) {
String[] cols = new String[]{
"Name", "Aktiv", "Sotierung"
};
return cols[pos];
}
public int getRowCount() {
return data.length;
}
public int getColumnCount() {
return 3;
}
public boolean isCellEditable(int row, int column) {
return true ;
}
public void addRow(int position) {
position = Math.max(0, Math.min(data.length, position));
Object[][] newObjects = new Object[data.length + 1][];
System.arraycopy(data, 0, newObjects, 0, position);
System.arraycopy(data, position, newObjects, position + 1,
data.length - position);
newObjects[position] = new Object[getColumnCount()];
data = newObjects;
fireTableRowsInserted(position, position);
}
public void addRow(test entity, int positionRow){
addRow(positionRow);
data[positionRow][COL_POS_NAME] = entity.getName();
data[positionRow][COL_POS_AKTIV]= entity.getAkiv();
data[positionRow][COL_POS_SORT] = entity.getSortierung();
}
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col);
}
public void deleteRow(int positionRow) {
list.remove(positionRow);
holeDaten();
}
@Override
public Object getValueAt(int rowIndex, int columnIndex)
{
return data[rowIndex][columnIndex];
}
}
[/code]
