Thread: JTable CheckBoxes

I have a JTable, X Rows by 4 Columns. The first column is text, but the other 3 are CheckBoxes. I am attempting to make it so when 1 CheckBox is selected, the other 2 in its row deselect. However I cant seem to get that to work. To specify, the Checkboxes just don't deselect.

Here is my current attempt:

table.getColumnModel().getColumn(1).setCellRenderer(new TableCellRenderer()
{
	public Component getTableCellRendererComponent(
		JTable table, Object value, boolean isSelected,boolean isFocused, int row, int col)
		{
			boolean marked = (Boolean) value;
			JCheckBox rendererComponent = new JCheckBox(modelSel.get(row).B717+"");
			if(marked)
			{
				rendererComponent.setSelected(true);
			}
		return rendererComponent;
		}
	});
DefaultCellEditor cellEditor1 = new DefaultCellEditor(new JCheckBox());
cellEditor1.setClickCountToStart(1);
cellEditor1.addCellEditorListener(new CellEditorListener(){
	public void editingCanceled(ChangeEvent e)
	{ 		}
	public void editingStopped(ChangeEvent e)
	{
		if(((JCheckBox)((DefaultCellEditor)e.getSource()).getComponent()).isSelected())
	    	{
	    		data[table.getSelectedRow()][2] = false;
			data[table.getSelectedRow()][3] = false;
		}
		else
		{
	    		data[table.getSelectedRow()][2] = true;
			data[table.getSelectedRow()][3] = false;
		}
	data[table.getSelectedRow()][1] = ((JCheckBox)((DefaultCellEditor)e.getSource()).getComponent()).isSelected();
	}
});
table.getColumnModel().getColumn(1).setCellEditor(cellEditor1);

In this attempt, I tried to make the values change in the CellEditorListener, but that doesnt seem to do it.


On a parallel, I have an issue when I close my JDialog when it reference those cells. It should try to find the column in each row that has a check, and set the value that corresponds to that column.

For a 5 Entry Test, I make the following Selections at Runtime:
Entry 1: Column 2
Entry 2: Column 3
Entry 3: Column 1
Entry 4: Column 2
Entry 5: Column 3

My printout is:
Entry 1 chose B737
Entry 2 chose B717
Entry 3 chose B717
Entry 4 chose B737
Entry 5 chose Blended

The printout should be:
Entry 1 chose B737
Entry 2 chose Blended
Entry 3 chose B717
Entry 4 chose B737
Entry 5 chose Blended

I would think the problem is most likely a result of my selections not working correctly, but I'm not totally sure of that yet, and I wont be until I get the selections working right.

tempDialog.addWindowListener(new WindowAdapter()
{
	public void windowClosing(WindowEvent e)
	{
    		for(int i=0;i<data.length;i++)
    		{
    			String name = data[i][0].toString();
    			int index = -1;
    			for(int x=0;x<marketList.size();x++)
    			{
    				if(marketList.get(x).Name.equals(name))
    				{
    					index = x;
    					break;
    				}
    			}
    			int number = 0;
    			Object[] it = data[i];
    			if((Boolean)(data[i][1]))
    			{
    				marketList.get(index).Cost = modelSel.get(i).B717;
    				System.out.println(name+" chose B717");
    			}
    			else if((Boolean)(data[i][2]))
    			{
    				marketList.get(index).Cost = modelSel.get(i).B737;
    				System.out.println(name+" chose B737");
    			}
    			else if((Boolean)(data[i][3]))
    			{
    				marketList.get(index).Cost = modelSel.get(i).Blended;
    				System.out.println(name+" chose Blended");
    			}
    			else
    			{
    				System.out.println("Error with "+name);
    			}
    		}
    	}
});

Lol, nevermind. I figured both out like the second I posted this.

If anyone has a similar issue, I forgot the most important statement:
table.setValueAt(true,table.getSelectedRow(),1);

Adding those fixed both issues.
