tablemodel

问题 I have a problem with refreshing a JTable . I start with an empty ArrayList and after setting my choice of a combo box I load content to the ArrayList but JTable does not react to it - it remains empty. Is it a problem with a TableModel ?

问题 I have an issue with pass result-set from xaction to prpt. When I use a example prpt then modify it, the report is ok.

问题 I want to refresh a JTable after performing db operations like insert/update/delete without frame reload. Is there a programmatic solution to do so? 回答1: The answer depends on what type of TableModel you're using...and at what level the events are occuring. For example, if you have some kind of background Thread or "update" button and want to reload the content from the database, simple create a new TableModel based on the results from the database and apply it to the current JTable , this

问题 I am running a query on ID column but I don't want it to be visible in my frame/pane. How can I achieve this?

问题 Hi, I have created my TableModel and want to refresh JTable once I added a new row. What should be added to the listener to "refresh" JTable? public class MyTableModel implements TableModel { private Set<TableModelListener> listeners = new HashSet<TableModelListener>(); //List<Staff> staffs = Factory.getInstance().getStaffDAO().getAllStaff(); private List<Staff> staffs; public MyTableModel(List<Staff> staffs){ this.staffs = staffs; } @Override public int getRowCount() { return staffs.size();

问题 First of all, apologies for posting something perhaps a bit excessively specific, but I'm not very experienced with Swing, and can't seem to find good examples that fit my needs. So I'm trying to figure out the best way to implement the a dynamic GUI for choosing filtering criteria in Swing: The underlying model is a class containing a list of criteria that can be negated (i.e. applied with a NOT-prefix), and a property indicating whether these should be combined with AND or OR. The GUI would

问题 I want to display a database table as a JTable. I have never used JTable before so I googled JTable and TableModel.

Following is the code of custom TableModel. public abstract class
