Am trying to create a single JTable column that can have several different cell editors. Java seems to be bias to having 1 cell editor for the whole column.
For example in 1 column can I have
Row1 : TextBox
Row2: Check Box
Row3: Radio Buttons
Row4: JColorChooser
......
At the moment I can only have one CellEditor for the whole column which is not very helpful.
the default implementation offers to provide editors per column in the tableColumn and/or editors per class type by setting default editors ( JTable.setDefaultEditor(Class class, TableCellEditor editor) ). If you look at the getCellEditor method of JTable you see that first the tablecolumns are asked for an editor, and if this doesnt succeed a default editor for the class acording to the value at the passed grid position is determined.
If this does not fullfil your needs, you can still overwrite the getCellEditor method of JTable and return whatever editor is suitable.
regards,
stefan
Consider these hints and let me know if I can help U any further:
1)Extend JTable
2)setSelectionMode ListSelectionModel.SINGLE_SELECTION
3) implement getCellRenderer(row,column):
columnClass = getModel().getColumnClass(row)
return getDefaultRenderer(columnClass)
4) implement getCellEditor(self,row,column):
row = getSelectedRow()
columnClass = getModel().getColumnClass(row)
return getDefaultEditor(columnClass)
Try this;
public class MyTable extends JTable {
public TableCellRenderer getCellRenderer(int row, int col) {
Object o = getModel().getValueAt(row, col);
return getDefaultRenderer(o.getClass());
}
}
your tablemodel's getValueAt
must return an object type that maches the cell renderer setup with setDefaultRenderer(Class,yourcellrenderer)
