Problem on Swing TextArea
I want to display characters in TextArea with Upper case only. If customer input some data in a TextArea, by default the entered data should appear in Upper Case only in the TextArea, incase user enters in Lower case also. Can anyone please provide me a solution to my problem.
Thanks
Thanks alot its working with your solution. One more question What listener is used for JTextArea? for AWT TextArea, there is a textlistener, and writing code in textValuechanged() method, like this is there any way for JTextArea in Swings.
Thanks for your help,

How can I get a TextArea to show whatever item I click on a Checkbox?
Add an ItemListener to the CheckBox. In the itemStateChanged method of the listener, check the state of the CheckBox and add the appropriate text to the TextArea.

Problem in Swing tree root node when displaying Japanese
I'm trying to create a tree using DefaultTreeModel. The root node will display text in Japanese and the other child nodes are in English. My problem is the root node fails to show Japanese correctly (only squares are shown).
I've already set my font.properties.ja to display Japanese font for virtual font "dialog":
dialog.plain.0=Arial,ANSI_CHARSET
dialog.plain.1=\uff2d\uff33 \u30b4\u30b7\u30c3\u30af,SHIFTJIS_CHARSET
dialog.plain.2=WingDings,SYMBOL_CHARSET,NEED_CONVERTED
dialog.plain.3=Symbol,SYMBOL_CHARSET,NEED_CONVERTED
And I've checked the "Tree.font" of UIManager is:
Tree.font = javax.swing.plaf.FontUIResource[family=dialog,name=Dialog,style=plain,size=12]
I'm quite sure that my font.properties.ja is correct as all message dialogs in my app. shows Japanese correctly (also using the same dialog font).
I got stuck. Can anyone please give me some advice? Thanks in advance.hello!
first of all i am sorry that i cannot help u.
i am a java developer and start work on

in a textarea.when i run a code,this display only
square.
plz help me.i will be realy thankful to u.

Hi all. I've run into some design problems when trying to create a Swing app.
I've got a non-graphical class that emulates a power supply unit. Let's call it PSUnit. I have to create a GUI for PSUnit.
Every class designed to build a full GUI app uses PSUnit in some way (changes its voltage, displays voltage, turns it on, turns it off, etc.)
Here's the catch. Suppose I've got a class:
public class BuildingBlock extends JPanel {
// code includes a JTextBox displaying
// the current PSUnit voltage.
}another class is created for setting the voltage:
public class AnotherBlock extends JPanel {
// this class contains a JSpinner and
// a button that retrieves the JSpinner value
// and sets it as the current voltage of
// PSUnit
}When the button in AnotherBlock is clicked, I must notify the BuildingBlock class that a PSUnit has changed its state so it can update it's values and display the correct data.
I've tried to do this a few times but failed miserably, so I'm hoping you guys could help me out.
Please note that both of the above classes have some additional code and it's not very pleasant to make one class an inner class of another. I should be able to create a "standalone" classes which, combined together, form a GUI for PSUnit.
Thanks.Yes this is a common problem that many of us have when building UIs
Here's the question: In this instance, are these two classes really independant? Could they stand alone? Often when building a GUI, it's not even that easy to answer that question, but these leads to the two ways you can solve this
#1. Make them independent, and use listeners either using Observable / Observer or creating your own custom listeners. The advantage of this is smaller classes and more independence. The disadvantage is it's generally more complicated, especially at the design stage
#2 (what I'd probably recommend). Make 1 GUI class "MyPSFrame", then declare your panel classes as inner classes within that class. This way, everything goes into one spot, and everything is shareable. This also makes sense if you can't have 1 of the panels without the other. -
Hi, I am trying to develop a simple applet where a user can click on the screen to add jbuttons at the location of the mouse click. I have written an overly complex set of code that tries to achieve this goal, and in the end I have come close. My applet allows the user to input a certain number, and then click that many times on screen to create more jbuttons. The problem is that whenever the user clicks on screen a jbutton is created, but it only appears once the mouse has moved over it. I find this pretty weird, but basically when the user clicks, a jbutton is created within the program, but it is only "drawn" to the screen when the mouse moves directly over it.
www.geocities.com/nickv360
Can anyone explain to me why this is happening?
http://www.geocities.com/nickv360/Source/AirlineModel.java
http://www.geocities.com/nickv360/Source/City.java
http://www.geocities.com/nickv360/Source/DrawingCanvas.java
These are the source files if that helps at all. Addtinonally, the reset button doesn't work. The way the applet is supposed to be set up is to have an array of cities (JButtons) stored in DrawingCanvas. The drawing Canvas then accesses that cities[] array and adds each city[i] to the map. If there are no cities in the cities[] array, then no cities will be added. So, in order to successfully reset the map, here is what I do:
cities = new City[numCities];
removeAll();
index = 0;
repaint();
I change the cities[] array to a new array of cities. I use the removeAll() method to take away all the JButtons that are currently on the map, I reset the index counter, and I repaint. Unfortunately this doesn't work.
Does anyone know why Swing won't paint my buttons until the mouse moves over them, and why the reset method I've written doesn't work? Thanks in advance to anyone who can help.Just wanted to let people know that I found the answer:
As for the other problem, I think it has to do with you having overridden paint. Normally, when you call repaint on a container, it will automatically call repaint on all the components that it contains. I'm fairly certain that if you don't manually call super.paint(g); in your paint method, it won't do it for you.
Calling super.paint(g) makes the all of the bugs in the code disappear.
Thanks. -
Character reordering problem in swing text components on macintosh
I have created a swing application that handles devanagari script.(script for Hindi language).The application works perfectly in windows but in apple macintosh
there is a problem with the reordering of characters in text componets. Reordering means some characters needs to be displayed not in the exact order in which they are stored.I was wondering how this can happen as the application works fine on windows.Also other applications like text editor displays devanagari script correctly on macintosh.
I tried with several fonts like Arial Unicode MS,Devanagari MT etc/.javaVery odd. Post your Reordering code.

Hi,
I have a doubt in GridLayout and Threads. I�m doing one small application which is accepting images and Alphabets. Actually, What I�m doing running images and alphabets(combinedly) in frequent intervals. For this I used GridLayout and Thread concept. But I have a problem in paint method. How to call the GridLayout frequently. In GridLayout , I�m putting Images and alphabets. Acutually in paint method , there are only drawString or drawImage or other methods. Is it possible to call my layout. Is so, can anybody help me in this regard. Is there any way to do it . please suggest me.

I'm building I guess its like an online strategy game. On the map, when you move your mouse to within 50 of the bounds of the applet, it'll start scrolling the map at a predetermined speed.
When working with applets/painting/threads this worked like a dream. Java was too fast for itself and I had to even slow the scrolling down.
Now, I'm building the whole thing in swing instead. The map is technically a JLabel inside of a Container that gets loaded into the main contentPane.
The only way I could use setLocation in my threads run method was to setLocation on the Container, not the JLabel. Odd fix to that problem. (I kept getting a null pointed exception otherwise)
My problem is, when the mouse is in that 50 pixels, the program knows it, but it just /lags/. Horribly. I set a counter to print to the console and when the mouse enters the area it moves to like 15 (in 0.001 seconds), and stops. I move my mouse around, and a few seconds later I see 700-705, then it stops, and jumps ahead again if I move my mouse.
So my program will now scroll the map in very small, /very/ jagged bits.
It's not an intensive program or code. I don't see how or why the thread can't continually run it.
My run method:
public void run() {
while (true) {
if (mouseX > 650 && mouseX <= 700)
moveRight = true;
if (moveRight == true) {
if (mapCurrentX + screenX < (xDimension)) {
mapCurrentX -= moveSpeed;
contentPane.setLocation(mapCurrentX, mapCurrentY);
try {
// Stop thread for 20 milliseconds
Thread.sleep(20);
catch (InterruptedException ex) {
// do nothing
Thread.currentThread().setPriority(Thread.MIN_PRIORITY);
}I got this when I ran it ^_^;; Gonna try to fix it

I programmed a applet with swing, imbedded in html page. then opened a browser window to run it, everything was ok but the memory used was increasing with every clicking the applet. Anyone can help me?
I found out that only the window is not active the memory used goes down.This is the evidence that the garbage collector is running when necessary. So don't worry about it. Once your program uses too much memory (How much does it use anyway?), gc will kick in.
As your program runs on a computer in your company's hallway, it seems very unlikely there are other processes competing for memory. And I bet the window isn't active all the time day and night. :-)
If the memory problem concerns you very much, you can optimize your program by using static instances of frequently used objects instead of allocating new ones every time users click. -
Problems with swing, please help!!!

i have a JFrame class which has the main method placing a JComponent into its Container using the getContentPane().add method.

Problems with large textarea in ITS transaction
We have an ITS template which contains a <textarea>. This is working ok for some text, however most of the time when the user enters their text and clicks save the web page hangs.
In SM51 I can see the report name and the process running, but it isn't doing anything. It is then using up a huge amount of memory and causing a bottleneck.
I have put an external breakpoint in the PAI of the report, but the system doesn't get that far. It hangs before running any of the code.
We have recently upgraded from 46c with an external ITS to ERP6 with the internal ITS. This same transaction was working fine before the upgrade.
We have checked all the memory parameter settings we can see. The em/global_area_MB is set to 3GB and the text is only a few paragraphs long. Is there another parameter we can change?
The textarea source code is as follows.
<textarea cols="95" rows="10" name="ASI:95[]">
The SM11 trace files produce the following errors.

We have recently installed patch 178.
The problem is happening in IE and Firefox.
Is anyone able to help us resolve this issue?
Many thanks
KarenThe simplest solution is either to reduce the system load by stopping unnecessary processes or to increase the scope of the swap
When you set the memory for the integrated ITS (1), you determine the maximum amount of memory that the integrated ITS may consume.
When you set the number of slots in the template cache (2), you determine how much of this memory is to be used for the preparsed templates.
Changing the slots in the template cache has the following effect:
If you increase the number of slots, the template cache becomes larger. The performance of the ITS applications improves. However, there is less memory for ITS sessions, and you can run fewer ITS sessions in parallel.
If you reduce the number of the slots, the template cache becomes smaller. The applications take more time to run because templates have to be parsed again and again. There is more memory for ITS sessions, and you can run more ITS sessions in parallel.
If there is sufficient memory, set the number of slots so that there are always empty slots in the template cache. There is then no displacement in the template cache. (Best performance) -
Adobe acrobat causing repaint problems in swing app
Hello,
I am launching an external PDF browser from my swing desktop application using Process.exec(String[],String[],File) .
The problem is that once the adobe screen is visible (on top of my application's frame), moving it around causes the contents of my own frame to become "greyed out". The frame does not repaint itself until adobe is closed.
I have searched for similar problems on this forum with no success. Any ideas would be appreciated.
Thanks.That is usally an indicator that you have thread locked the Event thread.
Are you by chance calling
process.waitFor() on the returned process? -
Resolution problems with Swing, MigLayout, and Substance.
I've got some testers trying out my application on various systems. One computer is a Dell Mini and it is giving me some trouble with resolution. I am using MigLayout as the layout manager for every JPanel and for everything. I am also using Substance L & F. I thought this would be all I need to do to keep my application resolution independent. It appears that I have too many rows. The extra rows are getting cut off.
