#16250 — NetBeans Application with sortable Table and pre-existing frame/table code

I have an NetBeans application with a few controls. To this, I dragged a Swing Table control from the control palette. I'd like to use all of these and not use the below code.

The reason I don't want to use the below example is I cannot use the dragged in table above. I unsuccessfully tried to modify this code (the frame and table variable names) to use the above dragged-in table with its pre-existing frame. But, when I try to do that I get error messages such as "non-static method add (...) cannot be referenced from a static context". I even tried instantiating a class object, but received similar error messages.

http://www.java-tips.org/java-se-tips/javax.swing/sorting-and-filtering-tables.html

This linked example creates a table (columns which are sortable) but the new window is not docked anywhere.

Do you have a better example for me.

Thanks,

Each of those error messages can be solved by analysis and the right code changes.

Giving up on error messages is a recipe for failure.

Where's *your* code?

Do you have a better example for us?

How do I get this modified code to work.

I modified the working/good code from the attached link to the below code. The reason I do not want to use the code exactly on this link is it creates a new window and doesn't use the form that I already am using. The pre-existing form has jPanel1 (swing JPanel) containing jPanel3 (swing JPanel). And, jPanel3 contains jTable1 (swing JTable).

http://www.java-tips.org/java-se-tips/javax.swing/sorting-and-filtering-tables.html 

(jTable1 was dragged to the form from the swing control  palette. Design view shows a table with 4 columns and 4 rows, but the area is blanked out when I run the project!)

The below code compiles and runs, but the form's jTable1 is not populated with the data.

Thanks  for any help,

With the below, line of code I get the same result of no table displayed.

           jPanel3.add(pane);

#16347

The below 2 additional attempts also are failing (each yields the same result).  jInternalFrame1 (class JInternalFrame) was dragged to the designer form from the NetBeans swing Palette.

(Another Attempt)  
         JTable jTable1 = new JTable(model);
           RowSorter<TableModel> sorter =
             new TableRowSorter<TableModel>(model);
           jTable1.setRowSorter(sorter);
           JScrollPane pane = new JScrollPane(jTable1);
           //frame.add(pane, BorderLayout.CENTER);
           //frame.setSize(300, 150);
           jInternalFrame1.add(pane, BorderLayout.CENTER);
           jInternalFrame1.setVisible(true);


(And Yet Another Unsuccessful Attempt)  
           //JTable table = new JTable(model);
           RowSorter<TableModel> sorter =
             new TableRowSorter<TableModel>(model);
           jTable1.setRowSorter(sorter);
           JScrollPane pane = new JScrollPane(jTable1);
           //frame.add(pane, BorderLayout.CENTER);
           //frame.setSize(300, 150);
           jInternalFrame1.add(pane, BorderLayout.CENTER);
           jInternalFrame1.setVisible(true);

I don't think you want to be doing this. 
I presume the jTable1 already exists, and has a parent.

Nowhere that I can see are you setting the new table model in jTable1.

The code below works. It's just a basic JFrame app. created in NetBeans, with the code 
inserted to set the model/sorter for the default table. If you don't change the model
the code will throw OOB exception because the model data in the sorter only has 3 columns,
and the default table created by Matisse has 4.
