Positioning a JLable on a JFrame absoloutely

How can we position a JLabel on a JFrame at a specific position. I tried setLocation(x,y) but that does not seem to work. When i try setLayout(null) the jlabel is not displayed at all. What could be the soloution...

when you use this
setLayout(null)
you need this
setLocation(x,y)
and this
setSize(..,..)
or setBounds(..,..,..,..);

"relative" positioning of buttons in a JFrame

I want to draw an image as a background on a JFrame and then position several buttons in the frame such that when the frame is resized, the background is resized and the buttons remain "over" the same thing in the background image. I've tried to "do the right thing" and use a layout manager to position the buttons, but they just don't seem to behave like I need them to.
Is there an easy way to get a button to appear at e.g. 70% horizontally across the frame and 40% down the frame? And then when I resize, have the button still be 70% across and 40% down (based on the new size of the frame). Or should I just give up on the layout managers, and calculate my own absolute positions for everything?
Thanks

How to fix the position of JInternalFrames added in JFrame.

Hay Frnds, I am having a problem. I have a JFrame ,in which i have added five JInternalFrames. My problem is that i want to fix the position of thaose Internal frames so that user cant move them from one place to other. Is there any way to fix there position. Plz reply as soon as possible. Its very urgent.
Thanks.

import javax.swing.plaf.basic.*;
        BasicInternalFrameUI internalframeUI = (BasicInternalFrameUI)frame1.getUI();
        internalframeUI.getNorthPane().addMouseListener(new MouseAdapter() {
            public void mouseReleased(MouseEvent evt) {
                frame1.setBounds(0, 0, frame1.getWidth(), frame1.getHeight());
        });

Positioning JButton in a JFrame

Hello,
I am having a problem positioning a JButton in a JFrame. All I want to do is to have a JFrame that contains a JButton at location 100,100. I dont know why I've been having trouble with this. I just want something simple, so if anyone can write a small program that extends JFrame as an example for me that would be much appreciated. Thanks for your time everyone

For component positioning, Java use LayoutManagers which are placement algorithms.
By default, all components have a layout manager :
JPanels have a FlowLayout that layout the sub-components like a text document,
The contentPane of a JFrame has a BorderLayout which divides the screen in five areas (NORTH, SOUTH,EAST, WEST and CENTER).
If you want an absolute positioning you have to "remove" this layout manager and replace it by an "hidden" layout manager : AbsoluteLayout.
To do this use :
frame.getContentPane().setLayout(null);
After that you can give absolute positions and size to your components which won't be moved or resized.
I hope this helps,
Denis

JFrame array

I'd like to know if it's possible to get the position of a component stored in an array of JFrames.
For example:
JFrame jframe[] = new JFrame [5];
if i add a mouse listener to each of the components of the array, can i get the position in which the current jframe selected by the click of the mouse is stored?
example:
JFrame jframe[] = new JFrame [5];
MyMouseListener ml = new MyMouseListener();
for (int i=0; i<5; i++)
jframe.addMouseListener(ml);
then, inside the class MyMouseListener:
public void mouseReleased (MouseEvent e){
e.getSource() //and i get panel that was clicked but which position does it occupy in the array?
is there a way to get also the position in which the panel was stored in the array?
thanks a lot

Um. When I said Windows only, I should have said WinXP only. Does Vista even have Minesweeper? The install I've used doesn't have any games. And the program depends on image matching, so it won't work on Win98/95 unless the images are changed.
Vista is a pain. The company gave us Vista laptops, mine has been booted up about 10 times in the 3-4 months I've had it. And I still use my own XP laptop for my VFP development.
A tip that may some day come in handy: a freeware program I've had from Win98 days which runs perfectly ok on XP was crashing in Vista even after setting compatibility mode to XP, but did run ok when I setting the compatibility mode to Win2k.
XP SP3 isn't so hot either, after installing it my Intel motherboard CD can't run its autoinstaller. When I put in a new HD recently, I had to reformat and start over to be sure my chipset drivers were correctly installed.

Popup not in specified Component, but in main JFrame

Hi,
how do I make a popup appear inside the Component "owner" that is
given as parameter to the show method?
I have a JFrame containing a JPanel component in a GridBagLayout.
The JPanel has a MouseListener, causing "MousePressed" to show a
popup with a small textfield at the mouse position inside JPanel.
The popup is called as follows:
show(e.getComponent(), JTextField, e.getX(), e.getY());
I also tried giving explicit parameters: show(JPanel, JTextField, 10, 10);
However, the popup is not positioned inside the JPanel, but in the JFrame that
contains the JPanel.
Thanks for any help!
Regards,
Elke

Below is a test code I made.

Displaying images in an application frame

I'm trying to display a .gif in a frame. The first challenge is to turn the file(local) into an Image class. I don't know how to do that. Second is taking that Image and using Graphics to draw it. Alas, made necessary are "ImageObserver", "ImagerConsumer", "ImageProducer" and other such nonsensical classes. I've spent quite some time trying to figure this out
I feel bad wasting a post on something like this, but it seems to me like a valid question. It even says in the O'Reilly's Java in a Nutshell that images in Java are confusing. If there are links to good tutorials, or someone could post code for a simple Frame with a Graphics object that displays a .gif image from the same directory as the class I would appreciate it greatly.

I'm not sure why "Java in a nutshell" would say it's complex or confusing. But then that's the only O'Reilly book I've bought and didn't like. I prefer Bruce Eckel's "Thinking In Java"
In any case, let's look at images:
First, reference the "How to use Images" sectin of the Java Tutorial at http://java.sun.com/docs/books/tutorial/uiswing/misc/icon.html
The way I'd do it is to construct an ImageIcon class using
public ImageIcon(String filename)
Now, ImageIcon and Image are not derived from Component, so you can't put them into a Frame. BUT, you can put a JLable into a JFrame and the JLable can have an image. So you construct a new JLable like this:
ImageIcon myIcon = new ImageIcon("/images/duke.gif")
JLabel myLabel = new JLabel(myIcon);
Then put myLabel into your JFrame
myJFrame.getContentPane().add(myLabel);
(or put it in whatever layout manager and panel you are using within yoru JFrame)
That should do it. If you're going to be putting your code into a jar file then there is an additional bit of code that needs to be added. If you search for "Images jar" you'll find lots of discussion. Or you could go to my site at www.brouelette.com and look at the code for "One Hour Wumpus" to see the ImageLoader that I use that works in or out of a jar file.
Good luck.

How to create an

Hi folks,
I'm having a weird problem to solve.
I have a JFrame, displaying some texts (JTextpane).
Now, I want to open a Search dialog, entering some word into its text field, press "Search" button of the dialog and set the caret to the first occurance in the text pane that is located in my JFrame.
But I don't want the dialog to dispose nor hide. It just shall lost its focus (because the JFrame has the focus now). Clicking on the dialog again should give it the focus for changing the search phrase or go on with search.
It's exactly the behaviour like the "Find" dialog in eclipse has.
Oh, and I'm stuck to use Java 1.4.2, any other version.
I played around with this a while and the best I can get is an always-on-top dialog WITH the focus. But I need to edit texts while displaying this dialog in JFrame, so it's not good enough.
I also can not position the dialog beneath the JFrame, because its full screen.
Can anybody help me? I nearly lost y nerve.

Well, thank you VERY much!
That did it!
(I can't believe, I didn't try that. Shame.)

Displaying Korean in Frame style standalone application

I have desktop application and its user interface implemented in Frame class. I want to display/enter text in korean lang. I have
res-ko_KR.properties file contains korean equivalent texts. I also used native2scii with UTF-16 encoding on the prop file. However application doesn't show korean text. The app is running on Windows 2000 regular english edition and has korean fonts and IME installed.
Do I have to set font to Frame object or something like that?
I read on Font.Properties but just couldn't summerize how to use it and not sure if this a way to approach my problem.

In Jframe I added one rootPanelI don't know what a rootPanel is or why you think you need to add one.
The general code should probably be something like:
frame.add(userPanel, BorderLayout.CENTER);
frame.add(buttonPanel, BorderLayout.SOUTH);
frame.pack();Read the section from the Swing tutorial on [Using Layout Managers|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html] for more information and working examples.
For more help create a [SSCCE (Short, Self Contained, Compilable and Executable, Example Program)|http://sscce.org], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.

How to make JFrame positioned to lower right corner of user's desktop

I'm a new java user, and I'm working on building a small
application. When the application is launched, I would
like the application (JFrame) window to be positioned
in the lower right corner of the user's desktop. Does
anyone know how to get the user's desktop size so
I can position the application.
Here is a code snippet where I lauch the app.
public static void main(String args[]) {
ArchiveRestore mainFrame = new ArchiveRestore();
mainFrame.setSize(500, 500);
mainFrame.setTitle("Master Model Automation");

Initial vertical positioning in JFrame

In my frame(using GridBagLayout) I have several components, out of which some are not visible in the beginning. The problem is that the components that are visible in the beginning are positioned in the center of the screen, and when the rest of the components become visible, those components change position according to the space taken by the "new" components. So I would like the components' position to be initially static.
Hope this is clear enough...
There is a short piece of code, which demonstrates the prob...

Positioning Caret when Loading JFrame

Hi all,
My Question is that wether it is possible to position caret(Blinking cursor) when loading a JFrame..
Say for example my JFrame has a JTable and i want to position the caret in the JTable First row/First Column During runtime itself.. when loading it self the caret has to be displayed..
Thanks in Advance...
regards
Vijay

hi,
here is my code it is working but the problem i am facing is that... when the frame loaded i dint capture the
caret rather if i pressed any key the caret will position ... and i can type any language(say for example japanese) this is happening only for the particular cell if i press tab the cursor is not moving to the next cell..what to do any idea.......

How to position JFrame on Screen

Hi
I am using Netbeans 5.0 for GUI. I want to specify a particular size to my JFrame and position it to the center of my screen.
How do i do that ?
I tried maximumBounds which works only when I maximize application window.
Is there any other property available in netbeans that i should use?
Thanks
Nagarajan

frame.setLocationRelativeTo( null );
