jtable

问题 I am new to JAVA and I am trying to make a JTable. What I want is that whenever a user make a selection from the comboBox in the Jtable, the Jtable will put the current date in the cell next to the comboBox. I wrote a code, but the code cannot upate the cell value. Here is my code(I just want the Jtable to insert "a" at row 1 column 4 for right now). public class GChamber extends JPanel { private boolean DEBUG = true; ListSelectionModel listSelectionModel; public GChamber() { ... JTable

问题 I'm trying to implement the MVC on a test example. How can i update the table when there is a change Class: Model class valueUpdater extends Thread { private String sValue; public valueUpdater() { this.start(); } public String getValue() { return this.sValue; } public void run() { try { for (int i = 0; i <= 100; i++) { this.sValue = String.valueOf(i); try { Thread.sleep(2000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } catch (Exception e)

问题 In my JTable, all my checkboxes are in column 3. after I onclick a button, it will remove those rows that are checked. But however after implementing the functions in my onclick. It does not remove the the rows. The method for the button listener class DeleteBtnListener implements ActionListener { @Override public void actionPerformed(ActionEvent arg0) { for(int row = 0; row < table.getRowCount(); ++row) { if((Boolean) table.getValueAt(row, 3) == true) { myTableModel.removeRow(row); table

问题 So this is probably a silly question but I just cant figure it out. Basically I have my MainWindow, when I press a button a new window should appear named PartSelectionWindow that contains a JTable (the JTable is filled out with a custom table model). Then I select a row and press ok to go back to the MainWindow and work with the info selected. Here's the problem: If I use a JFrame for the PartSelectionWindow, after the window is closed the code execution does not continue in the MainWindow
