I have a JTextField that a User and an Admin update to try and solve a problem that a user may have. Although when I setText(conversation) to the JTextField the text starts in the middle and when it goes to the end of a line it does not go to a different line. Can I set the JTextField so that text begins at the top? and when the user/admin gets to the side of the text field it goes to another line? I have tried looking this up everywhere and can not find an answer
here is a picture of the window with the conversation text field
Just noticed that you are using a JTextField. JTextField is a single line and will hence print the text that appears to be center aligned. You should be using a JTextArea instead that that is multi-lineand it will solve your problem

I have a JTextField on my first GUI window. Later in the program I open another GUI and go to display the value of the JTextField but in the program I get an error of invalid layout. I'm not sure what I need to change to get it to display the correct value.
Picture for reference
JLabel supfirst = new JLabel("Supervisors First Name :" + firstvalue.getText());
.getText() is probably what you're missing.
This is what displays the content from the input field.
I'm trying to create one search toolbar that appears inside the letters hidden stick. when I press the hidden letters that when the bar disappears and there's no hiding the letters that appear. I've tried to capture events keyPressed entering the search bar, but I do not really feel comfortable with that way. if anyone has a better way, I hope everyone helps do.cam Thanks!

Check out the Text Prompt.
You can control when the prompt disappears. You can also control the color and style of prompt.
The Text Prompt uses a DocumentListener and a FocusListener to determine when the prompt should be displayed.
You can use the default settings with a single line of code:
JTextField textField = new JTextField(10);
TextPrompt tp7 = new TextPrompt("First Name", textField);
In JFrame Form I have added a jTextArea and added a text into it, while still in design mode. But when I run the form I want the text to be invisible, which is not happening. I checked the properties of the JTextArea but I am not really sure how to change the visiblity of the text..
For clearing the JTextArea filed you need to set its text as empty.
For this you need to see JTextArea#setText as null or "".Try this code at the execution of your application.
jTerxtAreaObject.setText("");
Set the color of the text as the same color as the background.
I am writting a simple server chat client using gui to make the chat box and so on. I am simply wondering if I should use jtextarea instead of jtextfield if someone wants to write a long message since jtextfield does not allow word wrap.
Does it matter if I use jtextarea of jtextfield or is there a specific reason not to use jtextarea as my input box?
My guess:
You'll probably need both a JTextField and a JTextArea (or other multi-line text component).
The JTextField would be for the user to type in their chat messages to be sent. It would be editable.
and the JTextArea would show the incoming chats as well as the chats the user has sent. It would not be editable.
Consider placing the JTextArea in a JScrollPane
Consider placing both in a BorderLayout-using container with the JScrollPane that holds the JTextArea placed in the CENTER position and the JTextField in the SOUTH position.
A JTextField is a little easier to work with. You can add an ActionListener to it so that when the user hits enter the Action can be invoked an the message will be sent. Of course you can still have a "Send" JButton. the user can click on as well.
With a JTextArea, the Enter key will add a new line, so it you want the user to be able to sent the text when Enter is used you will need to customize the processing, maybe by using Key Bindings. I would prefer the text area because I like to see as much of the text as possible, like I am doing now as I repond to this question.
From oracle docs and personal experience, the JTextField makes life a lot easier as the ActionEventListener is set by default so the actions(characters or text) set in the field are copied to the JTextArea which is like a log of activity carried out in the field.
So the ball is in your court. You can use it JTextField together with JTextArea or JTextArea alone and write the listener class to suit you purpose and certainerly added a listenable event e.g a button.
Besides, always specify the size of the field to avoid layout issues that may compromise the Ui of your application as there is always a dynamic resizing if the size is not specified out rightly.
I have a few text areas that are filled with loops of information. Is it possible to make it 'jump' or scroll back to the top automatically after the loop has completed, so that the user sees it from the start and not the end?
You can use setCaretPosition() to set the cursor at position 0 of the TextArea. That usually works for me.
Use setUpdatePolicy with NEVER_UPDATE, and make sure the setUpdatePolicy comes before setting any text to the JTextArea. In my example I initialize a JTextArea without any text and call setUpdatePolicy right after.
JTextArea jTextArea = new JTextArea();
((DefaultCaret)jTextArea.getCaret()).setUpdatePolicy(DefaultCaret.NEVER_UPDATE);
I have solved this problem by creating a new TextArea which acts as a sort of buffer (and isn't displayed). The loop writes to this area and when completed gets the text from that and sets it to the required TextArea.
