jradiobutton

问题 I have added radio buttons to a JTable using renderer and editor. I have also created group for the same. I'm unable to achieve the exclusiveness (only 1 radio button should be selected) using this principle. Please see my code below and appreciate your response. Renderer and Editor classes: class RadioButtonRenderer implements TableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if (value =

问题 I am populating Employee Data in JTable using Netbeans. I want to add Radiobutton in each row, so that user can select any row and can perform actions like Update/Delete,etc. Here is my code for TableModel: DefaultTableModel model = new DefaultTableModel(); model.setColumnIdentifiers(new String[] {"Select","Employee ID","Name","Surname","Birth Place","Genre","Home","Marital Status","Phone","Age","Department"}); try{ con = DriverManager.getConnection ("jdbc:mysql://localhost:3306/"+database,

问题 I been learning about java for some time now and even bought several books to help me along. i am now in at the point in my journey that i want to learn about collections. i am able to use array lists in a very basic ways but i would like to understand how they work when use in conjunction with J radio buttons and other swing components. I been working, watching YouTube videos and reading books such as "Introduction to Java Programming- Comprehensive, 10E" and "Java in a Nutshell - (6th E) O

问题 In my problem I have an opaque JPanel and another JPanel that is translucent(semi-transparent) which sits on the first JPanel. When I have added radio buttons onto the top JPanel. The problem is every time I enter mouse over the area of the label of each radio button(and every time I move mouse away from the label), it gets darker and darker. package trial; import java.awt.Color; import javax.swing.ButtonGroup; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing

问题 I'm doing a project (something like a restaurant) for collage, and I'm not very good in Java (they didn't really try to teach us). The principle of the project is to show a message saying what radio buttons and check boxes I've selected. I have 5 radio buttons, they are for selecting a meal, and 5 check boxes for selecting a side dish. I've managed to have the radio buttons work but I don't know how to make the check boxes work... This is the code for the radio buttons (this goes for all 5):

问题 Is there any way to associate a group of JRadioButtons with a data model so it is easier to tell which button (if any) is selected? In an ideal world, I would like to associate a group of N radiobuttons with an enum class that has a NONE value and one value associated with each radiobutton. 回答1: I solved my own problem, this wasn't too hard, so share and enjoy: import java.util.EnumMap; import java.util.Map; import javax.swing.JRadioButton; public class RadioButtonGroupEnumAdapter<E extends

问题 I'm working in a project where I need to add a key shortcut for each JRadioButton , while looking on another similar question and as I'm using some other custom Action s I decided to use the method setAction on each of my JRadioButton s, however it requires me to press ALT + 1 - ALT + 5 to "trigger" the actionPerformed method of my CustomAction class. How can I modify this class in order to just press 1 - 5 and get the same behaviour? This is the code I made that demonstrates this issue:

问题 I have a bunch of dynamically added panels that contain radio button and a panel with several labels bind to radio button. Suppose I have a button that should retrieve container with labels bind to selected radio button or let's say another words - data bind to selected radio button. But how to get this container? Here is my code where I try to do this (in fact this is a stub to show what is going on on UI (view) side): public class Test extends JFrame { public static ButtonGroup radioButtons

问题 i have this class: public class TF extends JPanel implements ActionListener { private ButtonGroup buttonGroup = new ButtonGroup(); private JRadioButton rdbtnFilm; private JRadioButton rdbtnSerieTv; private JPanel pnlGeneral; private JPanel pnlRadioButton; private JLabel lblTitolo; private JTextField tfTitolo; public TF() { pnlGeneral = new JPanel(); pnlRadioButton = new JPanel(); rdbtnFilm = new JRadioButton("Film"); rdbtnFilm.addActionListener(this); pnlRadioButton.add(rdbtnFilm);
