scrollbars in JTextArea

Question

How do I add scrollbars to a JTextArea

User · Answer

I just wanted to say thank you to the topmost first post by a user whom I think is named "coobird". I am new to this stackoverflow.com web site, but I cant believe how useful and helpful this community is...so thanks to all of you for posting some great tips and advise to others. Thats what a community is all about.

Now coobird correctly said:

As Fredrik mentions in his answer, the simple way to achieve this is to place the JTextArea in a JScrollPane. This will allow scrolling of the view area of the JTextArea.

I would like to say:

The above statement is absolutely true. In fact, I had been struggling with this in Eclipse using the WindowBuilder Pro plugin because I could not figure out what combination of widgets would help me achieve that. However, thanks to the post by coobird, I was able to resolve this frustration which took me days.

I would also like to add that I am relatively new to Java even though I have a solid foundation in the principles. The code snippets and advise you guys give here are tremendously useful.

I just want to add one other tid-bit that may help others. I noticed that Coobird put some code as follows (in order to show how to create a Scrollable text area). He wrote:

JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);

I would like to say thanks to the above code snippet from coobird. I have not tried it directly like that but I am sure it would work just fine. However, it may be useful to some to let you know that when I did this using the WindowBuilder Pro tool, I got something more like the following (which I think is just a slightly longer more "indirect" way for WindowBuilder to achieve what you see in the two lines above. My code kinda reads like this:

JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(23, 40, 394, 191);
frame.getContentPane().add(scrollPane);

JTextArea textArea_1 = new JTextArea();
scrollPane.setViewportView(textArea_1);`

Notice that WindowBuilder basically creates a JScrollPane called scrollpane (in the first three lines of code)...then it sets the viewportview by the following line: scrollPane.setViewportView(textArea_1). So in essence, this line is adding the textArea_1 in my code (which is obviously a JTextArea) to be added to my JScrollPane **which is precisely what coobird was talking about).

Hope this is helpful because I did not want the WindowBuilder Pro developers to get confused thinking that Coobird's advise was not correct or something.

Best Wishes to all and happy coding :)

You first have to define a JTextArea as per usual   public final JTextArea mainConsole   new JTextArea        Then you put a JScrollPane over the TextArea  JScrollPane scrollPane   new JScrollPane mainConsole   scrollPane setBounds 10 60 780 500   scrollPane setVerticalScrollBarPolicy ScrollPaneConstants VERTICAL SCROLLBAR ALWAYS     The last line says that the vertical scrollbar will always be there  There is a similar command for horizontal  Otherwise  the scrollbar will only show up when it is needed  or never  if you use  SCROLLBAR NEVER   I guess it s your call which way you want to use it   You can also add wordwrap to the JTextArea if you want to Guide Here  Good luck  Norm M  P S  Make sure you add the ScrollPane to the JPanel and not add the JTextArea
