tablemodel

How do I display my "Click" objects in a JTable? ArrayList<Click> myClicks = new ArrayList<Click>(); Click click = new Click(620, 1028); Click click2 = new Click(480, 230); myClicks.add(click); myClicks.add(click2); It should look something like this: |---Mouse X---|---Mouse Y---| | 620 | 1028 | | 480 | 230 | Which is really... | | v v click.getX() click.getY() click2.getX() click2.getY() I don't want to use a 2D Object[][] because it makes more sense to keep them as Click objects as long as possible. I know I probably have to extend the TableModel interface but I'm not sure how. I'd just like

I am trying to make all the cells of a JTable uneditable when double clicked by the user. I have read a lot of forum posts and the general consensus is to create a new table model class, extend DefaultTableModel and then override method isCellEditable(int row, int column). I did all of this and now when I run my program (applet) Nothing shows up in the cells. NOTE I have a prof this semester that does not think applets are outdated... Code for the table model: public class MyTableModel extends DefaultTableModel { public boolean isCellEditable(int row, int column) //override isCellEditable /

I should tell this first, this is NOT about Rendering a Table cell. Here is the TableModel that i'm building using a 2D array based on a User object in my DB. List<User> userList = userManagerService.getAllUsers(); /* String[] col_user = {"Username", "Name", "Phone", .... } */ String[][] data = new String[userList.size()][col_user.length]; int i = 0; for (User user : userList) { String[] userdata = new String[col_user.length]; userdata[0] = user.getUserUsername(); userdata[1] = user.getUserName(); userdata[2] = user.getUserPhone(); userdata[3] = user.getUserNic(); userdata[4] = user

I'm building and app with multiple JTables and I need to detect when cell value change occurs so I can update it in the database. I tried TableModelListener and overriding tableChanged , but it fires only when I click away (click on another row) after I have edited a cell. Any other way to do this? You can implement the CellEditorListener interface, as shown in this example . Note that JTable itself is a CellEditorListener . It may also be convenient to terminate the edit when focus is lost, as shown here : table.putClientProperty("terminateEditOnFocusLost", true); More Swing client properties

I have a TableModel that may throw an exception on its setValueAt method if user enters an invalid value: public class MyTableModel extends AbstractTableModel { public void setValueAt(Object value, int rowIndex, int columnIndex) { String valueStr = (String) value; // some basic failure state if(valueStr.length()>5) { throw new ValidationException("Value should have up to 5 characters"); } this.currentValue = valueStr; } } Question is: how can another class catch this exception? It may show a popup message, or update a status bar, or paint the cell red. Whatever I chose to do, I don't think the

I want to make 25 JTables. I generate the table names by doing: for(int i=0; i < 26; i++) { TableNames[i] = "Table" + i + ""; ... How can I go about using these String names in the array as the new JTable names? i.e. TableNames[i] = new JTable(model){ ... Instead of an array, consider using a List<JTable> or List<TableModel> . Pass the name to the table's constructor or factory method. The example below uses the Component 's name, but a JComponent 's client property may be more versatile. Update : The revised Java 8 example below illustrates how to add new tables dynamically. import java.awt
