Thread: JDialog from JFrame button (GUI)

Hi

So I aim to make a GUI with 9 buttons, each one opening up a new window (JDialog) with input fields/tickboxes etc...

My code so far opens up a new Jdialog but does not display my added components (JTextFields) I cannot see why. My JDialog is just blank.
Any ideas?

public void actionPerformed(ActionEvent e) {
		Object s = e.getSource();
		if (s == addHose) {
			// JDIalog
			JTextArea addOwner, addNumberOfSections, addBore, addUsage, addLength;
			JRadioButton addHasTapAttachment, addHasJet, addIsOnDisplay;
			// buttons
			JButton btnOK, btnCancel;
			// variables representing user input
			String owner, numberOfSections, bore, usage, length;
			AccessibleContext hasTapAttachment;
			AccessibleContext hasJet;
			AccessibleContext isOnDisplay;
			JPanel main, addHosePanel;
 
 
			JDialog addHoseD = new JDialog();
 
			addHoseD.setLayout(new FlowLayout());
 
			addOwner = new JTextArea();
			addHoseD.add(addOwner);
			owner = addOwner.getText();
 
			addNumberOfSections = new JTextArea();
			addHoseD.add(addNumberOfSections);
			numberOfSections = addNumberOfSections.getText();
 
			addBore = new JTextArea();
			addHoseD.add(addBore);
			bore = addBore.getText();
 
			addUsage = new JTextArea();
			addHoseD.add(addUsage);
			usage = addUsage.getText();
 
			addLength = new JTextArea();
			addHoseD.add(addLength);
			length = addLength.getText();
 
			addHoseD.setTitle("Add Hose");
			addHoseD.setModal(true);
			addHoseD.setSize(250, 300);
			addHoseD.setVisible(true);

Right, ok.

I've added that code and it looks like this:



The text areas will just be attributes to my object (the hose) that the user will fill in.
