How to make JFrame window un-resizable?

I create a window using JFrame. I don't want user to re-size the window. How can I do that? Thanks!

JFrame f = new JFrame();
f.setResizable(false);
Jframe entends frame
setResizable() is a method in frame

How to make JFrame become the topmost window?

I have server that is supposed to show a TOPMOST JFrame window each time it gets a "Show Window" command from client. I use JFrame to create and show the window in the server code:
JFrame mainWin = new JFrame();
mainWin.setResizable( false );
Container mainContainer = mainWin.getContentPane();
mainContainer.setLayout( null );
// add components to mainContainer
mainWin.setVisible( true );
mainWin.show();
mainWin.toFront();
If I run the server under windows platform, the first created JFrame window is always hiding behind under other application windows. However, the JFrame windows other than the 1st one are always at top.
The BAD thing is, if I run the server under Macintosh platform, the JFrame windows are always hiding behind the other application windows.
Does anyone know how to fix the problem? i.e., making the JFrame window appear on top of other windows under any platforms?
Thanks.

p.s. I am using JDK version is 1.3.0.

there is some weirdness with java I've noticed under windows during development. When you start the app from a console window or script, if you change focus to another window before the first java window shows up, it will show up behind the window you changed focus to. If you leave it alone until the window shows, it will be on top. A work around is after you call show(), call toFront().

How to make jframe transparent?

Hi
some software's uses the monitor as a whiteboard to draw or to type text. How is this possible? I mean i thought that by making a jframe (full screen) transparent we should be able to do this? Is my understanding right? if so how to make the jframe transparent? when jframe is transparent will we be able to draw on it?

Try this:
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override public void run() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setUndecorated(true);
f.setBackground(new Color(0,0,0,0));
f.setExtendedState(JFrame.MAXIMIZED_BOTH);
f.add(new JComponent() {
@Override protected void paintComponent(Graphics g) {
g.setColor(Color.BLUE);
((Graphics2D)g).setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g.fillOval(0, 0, getWidth(), getHeight());
f.setVisible(true);

How to make dos window scrollable under win98?

Hi, I am using win98, every time when I run my GUI application, whenever I got bunch of error message that can not be displayed in one window, I will miss the original error information. Can anyone tell me how to make my dos window scrollable so that I can view all error message.
Thanks a lot.

I don't think that you can do this. There is another way, however: When java throws an exception, if it is not caught in your program, it is sent to the standard error, which is the console. You can simply reset this to be a file, so you can read this to get all the error info. Try using the following code in your main method:
public static void main(String[] arg) {
    try {
      System.setErr(new PrintStream(new FileOutputStream(new File("Errors"))));
      //instantiate your main class here
      MyClass mc=new MyClass(); //or whatever
    } catch (Exception _ex) {
      System.out.println("An error occurred"); //exception get sent to standard error automatically, so there
                              //is no real need to catch this exception. However, I use it to display
                              //a message on the console to let me know an error has occurred.
      System.err.println(_ex.getMessage()); //and finally, print the exception to file
      _ex.printStackTrace();
}

How to make a window fixed in size

Hi,
Is there a method with which I can prevent the user from resizing the current window/Form
Secondly, which event is generated when a window is resized?
Thankx in advance...

1. You can use the setResizable( false ) method of the Frame class.
2. You will need to add a listener to the addComponentListener() method of the Frame

How to make JFrame scrollable?

How can I make a JFrame scrollable? So that when I resize the JFrame to a smaller size the contents remain accessible? The way it is now is that when I resize a JFrame I can't access the components that fall out of the window (I'm using absolute component positioning within the JFrame). I thought adding two scrollbars to take care of this would be easy, but so far I haven't been able to get it right. Any suggestions would be appreciated.

Why dont you put all your components in a JPanel, add a scrollpane to it and then add that JPanel to
ur JFrame.

Pheeeewww...
Don't people ever search the forum and read older posts?
Both the question and the partly wrong answer have appeared many, many times before.
In pre-1.4 Java you simply cannot maximize a frame.
The 'solution' is probably the best you can do, but it does not really maximize the frame:
* The user can still move/resize it.
* It does not take into account the size/position of the windows task bar or any other window manager palette windows.
There also has been a solution that uses the Robot class to simulate a click on the maximize button, but that's a real dirty trick, that won't work in applets and strongly depends on the exact layout of the window's decorations.
In Merlin you can programatically maximize a frame as well as find out the screen's insets (resulting from the task bar...)

How to make New Windows open where I want!

Every time I launch Safari, it opens the window on the left side of the screen. How to do get it to open on the right side? I'm sure there is a keystroke combination to reset the default position or AppleScript, but I can't find one. Any help would be greatly appreciated.
Thanks in advance!

I had the same problem way back. I finally gave up and now use the following applescript. Change the pixel coordinates of the top left and bottom right of the window, that appear in parentheses, to fit size of your screen. Mine is set for my 2x" early Cinema display.
javascript:self.moveTo(190,0);self.resizeTo(1150,995)
Make a bookmark put this script into the URL area of the bookmark (right side) and rename it to something like "my window size" and then put it in your bookmark bar folder. Then just click on it in the bookmark bar and window will move and resize to whatever you have entered in the parentheses.
Fair winds and happy bytes, Dave Flory

How to make safari window open up to my size pref

Sorry about the long subject title. Everytime I open safari on my Apple computers the safari window will open up in a different size or place. How can I set it to open to my own default like preference so that it covers the screen when I open safari.
Does that make sense?
Thanks!

Thanks alot for the quick response. However, my problem is that I do resize the window with the lower right drag every time I open safari. It doesn't seem to save the setting or something. If I stretch it out huge....next time I open, it will be tiny, (and hitting the green button doesn't fix it) or in a different possition.
Any other ideas?
Thanks!

How to make download window open to front

When I download a file, how can I make the download window automatically come to the front?

THANK YOU! I don't know which idiot thought of removing the downloads window in favor of that ridiculous menu but I've been tearing my hair out trying to fix it. The old window has everything you need in one easy window while the menu requires multiple steps to check EACH download. I was ready to drop release 20 and go back to 19.

How to make JFrame ToFront to all applications

HI
My problem is i have a JFrame where in i have a JCheckBock and when i check it my frame should be top from all applications opened(like MS Word,notepad or any window) and when it is dechecked it should be back when any application is opened . I tried in solaris by using toFront() but no result is found any suggestions please...

You should use JLayeredPane as container of your objects. It has a method called "setLayer", or similar, through which you can assign Z-Order to the objects contained in it.
See the JDK Documentation on "JLayeredPane" topic.
