jradiobutton

问题 Currently I'm getting the selected button in this way, but I don't if this is the right/best method. MAybe there something more easy or object oriented than this. private int getFilterType(JRadioButton... buttons) { for (int i = 0, n = buttons.length; i < n; i++) { if (buttons[i].isSelected()) { return i + 1; } } return buttons.length + 1; } 回答1: I like using the ButtonGroup itself for this. i.e., import java.awt.GridLayout; import java.awt.event.ActionEvent; import javax.swing.*; public

问题 Is there any code that I can use to pass value of selected radio button to another frame? This is my code: import javax.swing.*; import java.awt.*; import java.awt.event.*; public class bookBatman extends JFrame implements ActionListener { private JLabel jlbName, jlbTime, jlbPic, jlbDate, jlbDescription, jlbAuthor, jlbDateProduce, jlbDirector, jlbActor, jlbRate, jlbNoOfTicket, jlbPrice, jlbTotal; private JTextField jtfNoOfTicket; private JRadioButton jr1, jr2, jr3, jr4, jr5, jr6, jr7, jr8,

问题 I intend to write a program where I will give the user a choice to choose from a 8*8 matrix. Because my reputation is below 10 I can not include an image but rest assured its just a normal 8*8 matrix. I plan to visualize it in my Java program with 8*8=64 radio buttons. the user can choose only one radio button at a time so it means all 64 buttons will be of the same button group. Now, how can I manage the action listeners? it is impossible (really tiresome and boring) to set up 64 individual

问题 I want to replace the text in my radio button list by an icon. I've tried this: rotateButton = new JRadioButton(rotateIcon.getImage()); But this replaces the radio button and text by the icon.
