How can the code be compiled and executed for testing? It is incomplete and is missing a main method.

Had to post twice due to length.

Ok, that compiles and executes. Now what is needed to see the problem?

**Eric Cauley** · July 13th, 2021, 02:46 PM

If you compile and execute program, and click Previous Customer Tab, search for contact, I have a JTextArea box displayed. I want to attach a JScrollPane top this TextArea box.

In the code the text area box is searchResults, and the ScrollPane is sp. I can not seem to write the code in a way that the scroll bar is correctly displayed in the GUI. I am not sure what I am missing.

Is it something Im not coding correctly in my action listener method? Or some type of typo Im not seeing...

		gbc.gridx = 0;
		gbc.gridy = 2;
		sp = new JScrollPane(searchResults, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
		sp.setBounds(0, 0, 100, 100);
		panel2.add(sp, gbc);
		panel2.add(searchResults, gbc);

**Norm** · July 13th, 2021, 02:56 PM

something Im not coding correctly

The first thing I see is the component: searchResults being added to more than one container. A component can only be in one container.

I made this change to allow for testing:

//	    searchedContacts = readRecord(tfContactFirstName.getText().toUpperCase(), tfContactLastName.getText().toUpperCase(), tfContactEmail.getText().toUpperCase());
            searchedContacts.add("adasds\ndaddsd\n3333\n44444\n5555\n6666\n7777");   //>>>>>>>>> ADDED for testing

I thought potentially that could be an issue. How ever even when I only attached searchedResults to sp, and not add searchedResults to panel2 component it still does not display. I am driving myself nuts trying to figure out the cause behind not being able to add a simplistic scroll pane.

**Norm** · July 13th, 2021, 04:01 PM

I think a problem is with the use of setVisible to hide/show components. It may be confusing the layout manager.
I think a better solution would be to use CardLayout to swap between showing an input panel and the results panel.

**Eric Cauley** · July 13th, 2021, 04:04 PM

Ok, I will give that a try. Now that I have you on the phone, over all the rest of program looks solid? Or do you have suggestions tips on any thing that may help myself on my development?

**Norm** · July 13th, 2021, 04:11 PM

One comment on the code: many lines are too long. They should be folded so all of the statement can be seen on the screen without having to scroll right-left.

**Eric Cauley** · July 13th, 2021, 08:06 PM

Was able to fix by adding this line of coding.

				searchedContacts = readRecord(tfContactFirstName.getText().toUpperCase(),
						tfContactLastName.getText().toUpperCase(), tfContactEmail.getText().toUpperCase());
 
				lblContactFirstName.setVisible(false);
				tfContactFirstName.setVisible(false);
				lblContactLastName.setVisible(false);
				tfContactLastName.setVisible(false);
				lblContactEmail.setVisible(false);
				tfContactEmail.setVisible(false);
				searchContacts.setVisible(false);
				searchResults.setVisible(true);
				searchAgain.setVisible(true);
 
 
				searchResults.setEditable(false);
 
				for(int i = 0; i < searchedContacts.size(); i++) {
					searchResults.append(searchedContacts.get(i) + " ");
				}
				sp = new JScrollPane(searchResults, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
						JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
 
				gbc.gridx = 0;
				gbc.gridy = 0;
				gbc.ipadx = 400;
				gbc.ipady = 225;
				panel2.add(sp, gbc);
				repaint();
