CellComponent is used to create user defined editor renderer for quicktable.
Example class MyCell implements CellComponent { JCombobox myCombo = new JCombobox(); MyCell() { myCombo.addItem("Alive"); myCombo.addItem("Dead"); myCombo.addItem("Leave"); } public void setValue(Object value) { myCombo.setSelectedItem(value); //handle the case if null is passed } public Object getValue() { return myCombo.getSelectedItem(); //return "" if nothing is selected } public JComponent getComponent() { return mycombo; } public void addActionListener(ActionListener listener) { mycombo.addActionListener(listener) } } yourQuickTable.getColumn(1).setUserCellEditor(new MyCell());
Column.setUserCellEditor(CellComponent)
,
Column.setUserCellRenderer(CellComponent)

Method Detail |
public void setValue(java.lang.Object val)
public java.lang.Object getValue()
public javax.swing.JComponent getComponent()
public void addActionListener(java.awt.event.ActionListener listener)
e.g. If the cell component is a combo box public void addActionListener(ActionListener listener) { yourComboBox.addActionListener(listener) } So the combo box will notify JTable, whenever the data is changed. If the JComponent which you are using in your cellcomponent doesn't have a addActionListener method, or if the cell component only fires some other type event like itemChanged, then all you have to do is, notify the listener whenever there is a change in data using listener.actionPerformed(null); e.g class MyCellCompoenent implements CellComponent { ActionListener listener; ... public void addActionListener(ActionListener listener) { this.listener = listener; } public void valueChangedInMyJComponent() { listener.actionPerformed( null ); } }
