JFrame 1 and JFrame 2
Need help please.....
how to send a text from jTextField1 of JFrame 1 to jTextField2 of JFrame 2? i'm using netbeans.... thanks..
use something like this....
public class frame1 extends JFrame{
private JTextField text1;
public frame1(){
text1 = new JTextField();
JButton button = new JButton("My Button");
text1.setText("hello world!!!");
add(text1);
add(button);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
new frame2(this).setVisible(true);
public String getText(){
return text1.getText();
public class frame2 extends JFrame{
public frame2(frame1 frame){
JTextField text1 = new JTextField();
text1.setText(frame.getText());
add(text1);
}

Problem with JFrame and busy/wait Cursor
Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread. -
JFrames and Java3D simple problem
Hi ive created a program using jframes in Java and im wanting to move it over to java 3d but im having problems. Ive litterally just looked at java 3d so my knowledge is limited. All i want is to set up my canvas so that i have a Jframe panel on the right and a 3d ball on the left. Here's my failed attempt......

}It Compiles but the 3d ball and the Jframe gui are in different windows but i want them in the same window but i duno how ?Hi tesla66 I'm sorry if I didn't correct your code, but drop some new code trying to solve the problem. I've used the cube instead the sphere because it's easier to see is rotating but just change "new ColorCube(0.4f)" with " new Sphere( 0.4f )". I wrote even some coments tought they're helpful. Tell me if I solved the problem

Inability to draw simple graphics in Java properly (threads and JFrame)
I am trying to use a thread to continually draw randomly positioned and randomly sized squares in the middle of a JFrame window. I have got 'something' working with the following code, however when run, the actual window doesn't come up properly. If I resize the window it does, and I get the result I wanted, but when the window is first opened it does not fully draw itself on screen. Can anybody help here?

I can't don't understand code in netbean and it's about Jframe.
i use netbean to design 2 jframe with some buttons on both frame.
frame1 is login form, frame2 is mainform. i want to show loginform then click the button1 to show 2nd jframe.
then i click exit on 2nd jframe and it come back to loginform(frame1).
i do alot of search on the google and here. i know the basic to show a jframe using
setVisible or .show() .hide(), etc..
the problem is what is my jframe variable name in netbean?
i know i can create an jframe object
such as: JFrame frame1 = new JFrame(); etc.. (it's ok if the syntax is wrong for now).
When i use netbean, i drag the Gui components to the Jframe. The jframe is generated by netbean automatically.
When the main program runs, it calls main() method, follow by :
public void run() {
new LoginForm().setVisible(true);
new LoginForm().setVisible <--- setVisible(true) means show the form.
and is new LoginForm() create an object from LoginForm class.
public LoginForm() {
initComponents();
When it create a new object, it runs default constructor and calls iniComponoents and finally show the jframe.
my question is when you create object, you usually declare variable and use variable to hold reference to the object.
that's why i don't understand how it works here.
it only create news object, bu no variable to holding it. how do i control this Jframe to show and hide without a reference variable????????????

Encephalopathic . thank your reply so much. your reply is fast. i love it and love this forum.. LOLyou're welcome
i tried hand-written code, and it looks just fine when design few buttons, labels and textfields.
The adjustment of buttons(labels) are not that good on the frame.
However, when you use IDE, you can drag the button on any spot you like in the jframe.... and in the process not learn how Swing works, and lose flexibility and power. Sorry to sound conceited, but I'll match any of your netbeans-created GUI's with one of my own, and mine will likely be better -- and I'm not all that good at this just yet.
Much luck. -

}Now the problem I'm having is changing that class to a JFrame, it seems simple but I keep having problems like when it runs from another JFrame nothing pops up. I can do it like this:
FinalTest ft = new FinalTest();
ft.setVisible(false);
JPanel example = ft.contentPanehowever I will probably be marked down on this for bad code. I'm not asking for the work to be done for me, but I'm really stuck on this and just need some pointers so I can carry on with the project. Thanks,

I'd actually consider your GUI being a JPanel instead of a JFrame quite good design - makes it easy to put the stuff into an applet when necessary...
Anyway, you should set setVisible() to true to make it appear, not to false. Otherwise, I don't seem to understand your problem.That is actually my problem. I am trying to convert this JFrame to a JPanel -
Problem with refreshing JFrames and JDialogs
My program is based on few JDialogs and one JFrame. I'm still changing them, one time one of the JDialogs is visible, other time JFrame. During this change I call dispose() for one window or frame and I create (if it wasn't created before) other component and call setVisible(true) for it. Problem is that sometimes (only sometimes! like 5% of calls) my windows appears but they are not refreshing (not showing new objects added to their lists or sth like that) until I resize my window by dragging mouse on the edge of it. Is there anyway to ensure that window will be displayed properly?
I ran into this problem about a year ago...so I don't really remember but I think a call to validate(), or paint() or repaint() or something like that should do the trick (forgive me for not knowing the exact one but as I said it has been a while). Its been about that year since I stopped coding in java and moved to c#. You want the window to redraw its self what ever that is.

Problem with insets and placement within a JFrame.
I have written some code that actively renders (at about 100 fps) to a JPanel contained within a JFrame. The size of the frame and the size of the panel are both set to 1000 by 700 (odd i know..)
Everything seems to work fine and I have encountered insets before so when I am rendering I have been adjusting accordingly. However I have started to try and draw my own menu bar at the bottom of the panel and this is where I am having problems. Whatever I draw seems to be too low and disappears off the bottom. To solve this I tried getting the insets from the JFrame:
Insets insets = getInsets();
xAdjustmentLeft = insets.left;
xAdjustmentRight = insets.right;
yAdjustmentTop = insets.top;
yAdjustmentBottom = insets.bottom;When I do this on my vista machine I get insets of 3, 3, 23, 3 accordingly. When I print out the coordinates of mouse clicks I find that at the top left corner i get 3, 23 as you would expect. When I click in the bottom right corner of my screen I get 996 (ish), 716.
The 996 can be explained by the left inset and my bad clicking however the 716 bears no relation to the top inset of 23 or the bottom inset of 3 in any way .... I am doing something wrong or have I missed something such as by adding the JPanel to the JFrame I have added or subtracted a distance somehow?
I ran the program on my xp machine and got similar insets of 3,3,29,3. However when I click in the bottom right of the page I get exactly the same coordinates as on the vista machine .. this just doesn't seem to make sense?
I should probably also mention how the rendering works just incase ... I'm drawing to a VolatileImage which I then draw onto the JPanel using its own graphical context. Interestingly anything I render on the image at y coord of 0 appears correctly at the top of the screen .... which it shouldn't because of the inset ... I'm so confused.
I hope someone can help / understand my babblings. If you need more code I can post it.. just there's rather alot of it.Sorry, my bad I realised I was doing some rather stupid calculations elsewhere in the program. I have now managed to get my drawn bar where I need it to be on both machines.
However, if I am rendering a picture of 1000 by 700 and the actual screen you are seeing is something along the lines of 993 by 674 (values minus the insets) this means I am wasting time rendering a picture larger than I am actually displaying, how to be normally interpret the sizes, do they go to the very outside of the panel or the visual element inside it? I could easily just increase the JFrame itself to be larger say 1006 by 726 and have the image the exact size within that.
Whichever way I have solved my original problem so no worries. -
Problem with ScrollPane and JFrame Size
Hi,
The code is workin but after change the size of frame it works CORRECTLY.Please help me why this frame is small an scrollpane doesn't show at the beginning.
Here is the code:
import java.awt.*;
public class canvasExp extends Canvas
private static final long serialVersionUID = 1L;
ImageLoader map=new ImageLoader();
Image img = map.GetImg();
int h, w; // the height and width of this canvas
public void update(Graphics g)
paint(g);
public void paint(Graphics g)
if(img != null)
h = getSize().height;
System.out.println("h:"+h);
w = getSize().width;
System.out.println("w:"+w);
g.drawRect(0,0, w-1, h-1); // Draw border
// System.out.println("Size= "+this.getSize());
g.drawImage(img, 0,0,this.getWidth(),this.getHeight(), this);
int width = img.getWidth(this);
//System.out.println("W: "+width);
int height = img.getHeight(this);
//System.out.println("H: "+height);
if(width != -1 && width != getWidth())
setSize(width, getHeight());
if(height != -1 && height != getHeight())
setSize(getWidth(), height);
}I create frame here...
import java.awt.*;
import java.awt.event.*;
import javax.swing.JFrame;
public class frame extends JFrame implements MouseMotionListener,MouseListener
private static final long serialVersionUID = 1L;
private ScrollPane scrollPane;
private int dragStartX;
private int dragStartY;
private int lastX;
private int lastY;
int cordX;
int cordY;
canvasExp canvas;
public frame()
super("test");
canvas = new canvasExp();
canvas.addMouseListener(this);
canvas.addMouseMotionListener(this);
scrollPane = new ScrollPane();
scrollPane.setEnabled(true);
scrollPane.add(canvas);
add(scrollPane);
setSize(300,300);
pack();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
public void mousePressed(MouseEvent e)
dragStartX = e.getX();
dragStartY = e.getY();
lastX = getX();
lastY = getY();
public void mouseReleased(MouseEvent mouseevent)
public void mouseClicked(MouseEvent e)
cordX = e.getX();
cordY = e.getY();
System.out.println((new StringBuilder()).append(cordX).append(",").append(cordY).toString());
public void mouseEntered(MouseEvent mouseevent)
public void mouseExited(MouseEvent mouseevent)
public void mouseMoved(MouseEvent mouseevent)
public void mouseDragged(MouseEvent e)
if(e.getX() != lastX || e.getY() != lastY)
Point p = scrollPane.getScrollPosition();
p.translate(dragStartX - e.getX(), dragStartY - e.getY());
scrollPane.setScrollPosition(p);
}...and call here
public class main {
public main(){}
public static void main (String args[])
frame f = new frame();
}There is something I couldn't see here.By the way ImageLoader is workin I get the image.
Thank you for your help,please answer me....I'm not going to even attempt to resolve the problem posted. There are other problems with your code that should take priority.
-- class names by convention start with a capital letter.
-- don't use the name of a common class from the standard API for your custom class, not even with a difference of case. It'll come back to bite you.
-- don't mix awt and Swing components in the same GUI. Change your class that extends Canvas to extend JPanel instead, and override paintComponent(...) instead of paint(...).
-- launch your GUI on the EDT by wrapping it in a SwingUtilities.invokeLater or EventQueue.invokeLater.
-- calling setSize(...) followed by pack() is meaningless. Use one or the other.
-- That's not the correct way to display a component in a scroll pane.
Ah, well, and the problem is that when you call pack(), it retrieves the preferredSize of the components in the JFrame, and you haven't set a preferredSize for the scroll pane.
Please, for your own good, take a break from whatever it is you're working on and go through The Java™ Tutorials: [Creating a GUI with JFC/Swing|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html]

Problem with jframe has jtextfield and jpanel
hi all
i ve a jframe with some components on it
of these components a jpanel that i repaint each time i want
and a textfield for chatting between players
the problem is as follows
some times when i click the textfield after repaining the panel
it can not be activated and the caret does not appear
when i click any other component out or in the frame
and return i get it active and in a good state
i use single buffer for repapint
thanks for reading
i'm waiting for responseYour best bet here is to show us your code. We don't want to see all of it, but rather you should condense your code into the smallest bit that still compiles, has no extra code that's not relevant to your problem, but still demonstrates your problem, in other words, an SSCCE (Short, Self Contained, Correct (Compilable), Example). For more info on SSCCEs please look here:
[http://homepage1.nifty.com/algafield/sscce.html|http://homepage1.nifty.com/algafield/sscce.html]
Again, if the code is compilable and runnable more people will be able to help you.
Also, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, you will need to paste already formatted code into the forum, highlight this code, and then press the "code" button at the top of the forum Message editor prior to posting the message. You may want to click on the Preview tab to make sure that your code is formatted correctly. Another way is to place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
// your code block goes here.
// note the differences between the tag at the top vs the bottom.

Problem with JFrame, JInternalFrame and JDialog
problem solved..sorry
I have just found this post:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=302473
And the first way seems to be the only way to solve the problem... :(
Now the question is, does it exist a way to refresh a JFrame after that I have uset setVisible(true)?
If it does exist I could have something like this:
setVisible(true)
new panel(getInsets(););
contpan.add(panel);

Problem with JFrame, JPanel and getInsets()...
hi, this is my problem:
I have a JFrame and I want add a JPanel to its ContentPan, I need to know the JFrame's getInsets values to set (with setBounds()) the right dimensions of the JPanel, but if I call getInsets() before of setVisible(true) I obtain all 0 values, if I call setVisible(true) before of add() I obtain the right values, but the JPanel is not showed.
By now I have solved with this sequence:
new panel();
contpan.add(panel);
getInsets();
panel.setBounds();but I would pass the bounds values to my panel constructor, something like this:
new panel(getInsets(););
contpan.add(panel);Could someone help me?I have just found this post:

Swing layout/size problem with JFrame and JApplet.
I have a class that extends a JFrame, the classes layout is BorderLayout. I then have a class that extend JApplet, this classes layout is GridBagLayout (this class has a JTabbedPane - which contains JPanels). The problem I'm having is no matter how big I make the size of the applet or frame (using setSize), the applet/frame stays the same size - no matter how large I make it.
Can anyone please help?
