I tried to add JRadioButton
into JTable
by using CellEditor
and CellRenderer
, but I can't add JRadioButton
into JTable
. I am using NetBeans and backend MySQL. Please help me.
Edit: Thank you, but I have no idea about how to group JRadioButton
. Can you help me?
I have 4 columns .First column cell containing item name , second column cell containing quantity,3rd and 4th column cells contiaining JRadio Buttons.Then I want to grouping 3rd and 4th column cells containing JRadio Buttons in each row
Edit:If I try to add radiobutton in the customize code of jTable by using this,
new JRadioButton("a")
, then it'l come as, javax.swing.JRadioButton[,0,0,0x0,invalid,alignmentX=0.0,.....text=a],
in the column instead of button
It's not clear how you want to use JRadioButton
in a JTable
; consider these alternatives:
Use SINGLE_SELECTION
mode to select individual rows.
table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
Use a column of type Boolean.class
, which will be rendered using a JCheckBox
. This example limits selections to a single row.
Use a JComboBox
as an editor for mutually exclusive choices within a row.
Addendum: If JRadioButton
is required, they can be added to a JPanel
, as shown in this example due to @mKorbel.
Addendum: If each JRadioButton
has its own column, you can't use a ButtonGroup
because a single button is used for all cells having the same renderer. You can update other button(s) in the same row from your TableModel
, which should override setValueAt()
to enforce the single-selection rule that is usually managed by the ButtonGroup
. There's an example here.
Addendum: This example due to @Guillaume Polet illustrates a way to manage one radio button per row.
