Hi all
I am about building a java desktop application that query a database and show the results
the results are stoked in a jtable, to show the results, i did the following :
//tabledb: an instance of a class that execute the query and save the results in a jtable named donnee (tabledb.donnee, donnee is a field in the class retrieving data )
JScrollPane jScrollPane2 = new JScrollPane(tabledb.donnee);
JPanel buttonPanel = new JPanel();
JFrame fr = new JFrame();
fr.getContentPane().add( buttonPanel, BorderLayout.SOUTH );
fr.getContentPane().add(jScrollPane2);
fr.pack();
fr.setVisible(true);
its works fine, but now I am trying to show in the frame where i have entered the query: ie i dont wont to create another jframe to show the table of results
I tried this :
jScrollPane2.add(tabledb.donnee); //jScollPane2 is declared before, actually I am working with swing framework where I can drag and drop component (jScollPane2 is draged
// and droped into the main frame
JPanel buttonPanel = new JPanel();
this.getContentPane().add( buttonPanel, BorderLayout.SOUTH );
this.getContentPane().add(jScrollPane2);
this.pack();
this.setVisible(true);
but when i run the application i issued a query and no changes in the jScollPane2, no results
did i miss something or I have problem in my conception??
thanks in advance
regards rachid

jScrollPane2.add(...)That's not how to use a JSrollPane. Read the API and follow the link to the tutorial on How to Use Scroll Panes.
