Closing The JFrame without using setVisible(false)

Question

I am using a frame for creating table "public class createTable extends JFrame" this class is being used by two panels to display the data . in a last panel where I have put two buttons "ADD" for adding records to a access table and "RETURN" to return back , while closing the "createTable" frame.
On Clicking the "RETURN" button the code :
setVisible(false)
just closes the buttons in the panel whereas the original frame doesnot hides. whereas, if i use an instance of createTable:
private createTable ctbl;
and the have it as
ctbl.setVisible(false);
exception is thrown . as well as the method :
void remove(Container con) also throws exception and does not functions smoothly.
Can anyone please help me>>>>

Answer 1

The problem is probably that you're calling setVisible on the button, not on the frame.
If you maintain a reference to the frame then just do something like this:
frame.setVisible(false);If you don't then you'll need to work out which frame the button belongs to:
SwingUtilities.getWindowAncestor(this).setVisible(false);Hope this helps.
