jtable

问题 I want to make a JTable , where one single cell (not all rows of a column) will contain a JComponent like JdatePicker or JComboBox . I have written this code DefaultTableModel dm; dm = new DefaultTableModel() { public boolean isCellEditable(int rowIndex, int columnIndex) { return !(columnIndex == 0); //make 0th column non-editable } }; Object [] columnHeaders=new Object[]{"Field", "Value"}; Object [][] data=new Object[][]{{"ID",""},{"Reg Year",""},{"Reg Date", ""}} ; regFormTable.setModel(dm)

问题 I am querying a MySQL database via Java, pulling data out of the result set and placing it in a DefaultTableModel, which gets put in a JTable, then into a JScrollPane to get displayed. In the JTable, I enable sorting in the table via table.setAutoCreateRowSorter(true); However, if the cells in the row I want to sort are not of class String, then I get a java.lang.ClassCastException. The data in my table has the following classes: java.sql.Date java.sql.Time java.lang.Double java.lang.Boolean

问题 I'm using this method to convert minutes into time (hh:mm:ss) public static String time(double m){ double t = m; int hours = (int)t / 60; int minutes = (int)t % 60; double seconds = (t - Math.floor(t)) * 60; System.out.println(seconds); if (seconds > 59){ seconds = 00; minutes++; } String myFormat = seconds >= 10 ? "%d:%02d:%.0f" : "%d:%02d:%.0f"; String time = String.format(myFormat, hours, minutes, seconds); return time; } the time will return as a string, then I will post it into a jTable,

问题 i have been wondering for a long time, whilst creating several stupid solutions for this Problem, how the following should be done properly: DataTable: ID | givenname | lastname | address | data ... I want to show all givennames + lastnames in a listbox and uppon selection of one item, i want to retrieve the rest of the corresponding dataset and display is in some textboxes. So i basically do: 1) Query: SELECT ID, givenname, lastname FROM DataTable; 2) Create and ArrayList of "Contact Objects

问题 I have build code clone application, that using JCCD API that impelemnted ANTLR. To show the code clone, I am using a jtable. This is my screenshot Application : https://docs.google.com/file/d/0B_Rg--NnjJccMERpaTNidzR3cFE/edit?usp=sharing Okey, from the following screenshot above, I was success to compare one file to another one file. The problem is when I am compare a file to two or more files. The tables just give me the last suspect of code clone. But, in my netbeans output console, I was

问题 I have a sortable JTable; when a row is added I want to know its view -index. I tried using a table model listener like this: @Override public void tableChanged(TableModelEvent event) { if (event.getType() == TableModelEvent.INSERT) { int modelRowIndex = event.getFirstRow(); int viewRowIndex = table.convertRowIndexToView(modelRowIndex); System.out.println("viewRowIndex: " + viewRowIndex); } } This works if the table is not sorted. Unfortunately, if the table is sorted the conversion-method

问题 Question 1) I have a JPanel ps, which has a null layout; a JScrolPane scrollPane, and a JTable table. I have added the table to the scrollPane, and then added the scrollPane to the Jpanel ps. The following is my code for doing that:- ps = new JPanel(); ps.setLayout(null); ps.setSize(1000,600); scrollPane = new JScrollPane(); scrollPane.setBounds(10, 119, 975, 300); scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); ps.add(scrollPane); table = new JTable(data,

问题 When i want to get a cell value from my table (after search with filtering) and select that row and execute the returnAction() , Exception occur. My code: public class BookPage_User extends JFrame implements ActionListener { private JButton returnBookBtn; private JTextField filterTF; private TableRowSorter sorter; private JTable table; private BookJDBC bookJDBC; private BookModel model; public BookPage_User(String[] enterUserInfo, String userId) { bookJDBC = new BookJDBC(); model = new
