jtextarea

First of all I want to tell you that I want to keep a JTextArea stable. When I first create this area I make it with (30,50). When I change the font takes a bigger place in the JFrame,because textArea wants to keep the her properties at 30,50. With a big size in font(size=72) she is going bigger than the frame!!!How can I change the row values an the columns values to keep her stable at the frame? i forgot to tell that i used these methods i want to create a notepad and i want the lines and columns to resize automaticaly when the user changes the font or size of letters just like Microsoft's notepad does. Manual resizing is my worst solution also i have not understand why a JTextArea is becoming larger than my JFrameand also larger than my screen.

I need to format a few lines of text in a JTextArea/JTextPane/ JEditorPane. As a matter of fact I want to justify the lines on both left and right side. I wish I could explain my requirement. How can I do that. I'm using NetBeans 5.5 and the label so far is as follows jTextArea1 = new javax swing. JTextArea(); jTextArea1 setColumns(50); jTextArea1 setEditable( I need to format ( justifythe left and alter sides) ....................... .................... ......................... ................................................... ............. Hey,you can use these to display HTML formatted text. Put your text into a html document with the change by reversal formatting tags <center>... . with the change by reversal formatting tags <center>... That's not what OP required. Center is not the same as Justified.@OP: Check out this old forum thread with sample label (see reply #5): http://forum java sun com/thread jspa?threadID=289879 Please do not unnecessarily resurrect this thread from 2003-03 by posting there. But do express us here whether StanislavL's code correctly formatted by JimDinosaur solves this problem db Hi zedoo. Thanks a ton for answering my question. Your hint worked. Though not <center> tag but <justify> tag. The HTML tag matters little. The Idea is important. So thanks again. I undergo awarded u 5 points. As a be of fact I haven't been able to analyse Darryle Burkes suggestion yet. Though I already have copied his suggested code. I haven't been able to try it yet. I have kept the rest 5 points so that I may allocate it to him if his suggestion also works. If it doesn't I shall award the to u. Further. I'm extremely sorry for the delay. As a be of fact. I had an emergency requirement to learn STRUTS so I could not find out measure to try the codes u two suggested. Hope u concede me for the delay. The code that worked is as follows javax displace. JScrollPane();jScrollPane1 setHorizontalScrollBarPolicy(javax displace. ScrollPaneConstants. HORIZONTAL_SCROLLBAR_NEVER); jScrollPane1 setVerticalScrollBarPolicy(javax displace. ScrollPaneConstants. VERTICAL_SCROLLBAR_NEVER); welcomeMessage = javax swing. JEditorPane();welcomeMessage setEditable( The Webpage welcome html contains the text I was trying to justify. Its code is as follows.

This question is not answered. Helpful answers available: 2. Correct answers available: 1. [Update: If I remove the transparency everything is fine. However. I really need the transparency..] Hi. I have the simplest question but I can't seem to get an answer to it. The problem is very simple: I have defined a JTextArea and I'm reading text into it. The problem is that the old text does not disappear and the new text is pasted on top making it unreadable. As an "act of desperation" I fixed this by setting the area invisible updating it and setting it visible again as you can see in the label. It works but now it blinks in the screen (quite annoying!). Is there a smarter way to to this? I need this on a transparent window (see class init below) overlayed on another JFrame. I am on Mac OS X. I hope some of you can help me with this problemThanks a lot in advanceLele "http://localhost/~" ); this. kill setBackground(this. OverlayColor); this. kill setLocationRelativeTo( ); this. Overlay setUndecorated( ); this. Overlay setSize(width,height); System out println( y = f getLocation() y +f getSize() height - border_y - height; this. Overlay setLocation(x y); this. Overlay add(this. OverlayText); this. Overlay setAlwaysOnTop( ); this. OverlayText setLineWrap( ); this. OverlayText setForeground(alter. color); this. OverlayText setBackground(this. OverlayColor); this. OverlayText setFont( Re: Can't update text in JTextArea! Can you back up? Oct 25. 2007 4:48 PM(reply 1 of 4) For now with too few label and information. I can only say call setText("") before updating text area content. gratify construe: http://java sun com/docs/codeconv/And post a small show code that is generally compilable runnable and could create your problem. See: http://homepage1 nifty com/algafield/sscce html and http://www yoda arachsys com/java/newsgroups html Re: Can't modify text in JTextArea! Can you help? Oct 26. 2007 3:39 AM(say 2 of 4) Hi so this is the class. If I act it like this it simply overwrites old text with the new (like JTextArea thinks that the old text is a part of the background to be buffered). If I set it invisible and back to visible it works but it blinks. How can I let JTextArea understand that it shouldn't consider the old window as a background? Should I use another categorise?Pls act in object that I'm on Mac so maybe it's a Mac-specific thing but I'd desire to know.. ThanksLele ); this. Overlay setBackground(this. OverlayColor); this. Overlay setLocationRelativeTo( );.

can anyone help me im curious how can the compilers for java e g.: Netbeans. JCreator direct the dominate promt output to a JTextArea. can anyone guide me on what class to be at??thanks a lot you should be at. There's a displace forum. Ask Swing questions there. And search there too. I'm sure I have seen that one asked several times. be at System setOut() and the equally interesting System setErr() and System setIn(). To confine System out use a PrintStream wrapped around a ByteArrayOutputStream. The output will go to your ByteArrayOutputStream instead of the console and from there youcan act it wherever you want. After giving it more thaught here is how I evaluate it works. System setOut() can be redirected as I said in my previous post. Use PipedOutputStream not ByteArrayOutputStream. here is a simple categorise that redirects the standard output to a file called a txt you have to be into the class java class. System and other i/o classes for your inspect where output goes to a textArea you might wanna use a multithreaded solution redirect your output to a file as above and use the thread to read the file and attach text into your text area there is other better solution that directly passes data into the textArea i'll post it if can find it in my label base. i belive baftos got the exceed solution use this technique along with the thread where the go listens for the new data on the pis and on availability it posts the data to the text area Unless otherwise licensed label in all technical manuals herein (including articles.

Chapter 5 hold back Structures: Part 2 227 if ( grade != sentinelValue ) System out println( “The next grade is ” + grade ); This flexibility can back up a programmer express a condition in a more convenient manner. The application in Fig. 5.19 demonstrates all of the logical operators and boolean logical operators by producing their truth tables.
