Problems with resizing a JFrame

Hello people! I'm having a problem setting the size of a JFrame while it is visible. Just resizing it by hand with the mouse is no problems, everything works ok, but when I call the setSize(blabla) method, the contents of the window doesn't notice that it has more space to draw the components on. The result is that the extended area of the window is just plainly white... until I resize it by hand, then everything looks ok. Does anyone have a solution? repaint() doesn't help...

hay svenmeier...
I'm all confused with the pack() method... I don't like it :) It always sets the size 2 pixels too large in windows 9x/Nt/2k/xp. Of course that's adjustable, but I'm unsure whether it will be the same on all other platforms. It's just one problem that I have that I have never been able to solve. Asking people around here for a solution never helped, because it seems others do not have this particular problem.
So, to me it seems that the most reliable way to set the size of a frame is to first set it visible, and then resize it with respect to the insets.

Weird problem with jpanel vs jframe

I'm using jmathplot.jar from JMathTools which lets me do 3d plotting. I used a JFrame to get some code to work and it worked fine. Here's the code that worked for a JFrame:
public class View extends JFrame
    private Model myModel;
    private Plot3DPanel myPanel;
    // ... Components
    public View(Model m)
        myModel = m;
        // ... Initialize components
        myPanel = new Plot3DPanel("SOUTH");
        myPanel.addGridPlot("Test",myModel.getXRange(),myModel.getYRange(),myModel.getZValues());
        setSize(600, 600);
        setContentPane(myPanel);
        setVisible(true);
}Here's the class that starts everything:
public class TestApplet extends JApplet
    public void init()
        //Execute a job on the event-dispatching thread; creating this applet's GUI.
        try
            SwingUtilities.invokeAndWait(new Runnable()
                public void run()
                    createGUI();
        catch (Exception e)
            e.printStackTrace();
    private void createGUI()
        System.out.println("Creating GUI");
        Model model = new Model();
        View view = new View(model);
}And here's the Model:
public class Model
    private double[] myXRange,myYRange;
    private double[][] myZValues;
    public Model()
        createDataSet();
    public double[] getXRange()
        return myXRange;
    public double[] getYRange()
        return myYRange;
    public double[][] getZValues()
        return myZValues;
    private void createDataSet()
        myXRange = new double[10];
        myYRange = new double[10];
        myZValues = new double[10][10];
        for(double i=0;i<10;i++)
            for(double j=0;j<10;j++)
                double x = i/10;
                double y = j/10;
                myXRange[(int) i] = x;
                myYRange[(int) j] = y;
                myZValues[(int) i][(int) j]= Math.cos(x*Math.PI)*Math.sin(y*Math.PI);
}However, as you can see, my main class is a JApplet because ideally I want View to be a JPanel that I add to the applet. All I did was change "extends JFrame" to "extends JApplet" and changed:
setSize(600, 600);
setContentPane(myPanel);
setVisible(true);to
this.add(myPanel);and added these two lines to createGUI():
        view.setOpaque(true);
        setContentPane(view);When I run it however, it appears really really small. It seems like its drawing the panel to the default size of the applet viewer and doesn't resize it when I resize the applet. I don't know if it's a problem with the library or if I'm doing something wrong in my applet.

However, as you can see, my main class is a JApplet because ideally I want View to be a JPanel that I add to the applet. All I did was change "extends JFrame" to "extends JApplet" and (...)What do you mean? View extends JApplet? I thought View was meant to extend JPanel in the end...
When I run it however, it appears really really small. It seems like its drawing the panel to the default size of the applet viewer and doesn't resize it when I resize the applet.Or, the panel has its preferred size, and this latter is too small. Actually the panel has the size its container's layout manager awards it (taking or not the panel's preferred, minimum, and maximum sizes into account). See the tutorial on [layout managers|http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html] .
In particular, this line adds the myPanel to a parent panel (presumably, it is in class View which extends JPanel, whose default layout is FlowLayout):
this.add(myPanel);
I don't know if it's a problem with the library or if I'm doing something wrong in my applet.Likely not (presumably the library interfers only in how it computes the Plot3DPanel's preferred size). There's an easy way to tell: try to layout correctly a custom JPanel of yours, containing only e.g. a button with an icon. Once you understand the basics of layout management, revisit the example using ther 3rd-party library.
N.B.: there are a lot of "likely" and "presumably" in my reply: in order to avoid hardly-educated guesses especially on what is or isn't in your actual code, you'd better provide an SSCCE , which means reproducing the problem without the 3rd party library.

Problem with setContentPane() in JFrame class

I recently discovered a problem with the setContentPane method in the JFrame class. When I use setContentPane(Container ..), the previously existing contentPane remains in the stack. I have tried nullifying getContentPane(), and all manner of things, but, each time I use setContentPane, I have another instance of a JPanel in the stack.
I'm using code similar to setContentPane(new CustomJPanel()); and each time the user changes screens, and a similar call to that is made, the old CustomJPanel instance remains in the stack. Can anyone suggest a way around this? On their own the panels do not take up very much memory, but after several hours of usage, they will build up.

I tried what you suggested; it only resulted in a huge performance decrease. The problem with memory allocation is still there.
Here is the method I use to switch screens in my app:
public static void changeScreen (JPanel panel){
          try{
               appFrame.setTitle("Wordinary : \""+getTitle()+"\"");
               appFrame.setContentPane(panel);
               appFrame.setSize(appFrame.getContentPane().getPreferredSize());
               appFrame.getContentPane().setBackground(backColour);
               for (int i = 0; i < appFrame.getContentPane().getComponents().length; i++)
                    appFrame.getContentPane().getComponents().setForeground(textColour);
               //System.out.println("Background colour set to "+backColour+" text colour set to "+textColour);
               appFrame.validate();
          catch (Exception e){
               //System.out.println("change");
               e.printStackTrace();
And it is called like this:
changeScreen(new AddWordPanel());The instantiation of the new instance is what is causing the memory problems, but I can't think of a way around it.

Problem with JPanel in JFrame

hai ashrivastava..
thank u for sending this one..now i got some more problems with that screen .. actually i am added one JPanel to JFrame with BorderLayout at south..the problem is when i am drawing diagram..the part of diagram bellow JPanel is now not visible...and one more problem is ,after adding 6 ro 7 buttons remaing buttons are not vissible..how to increase the size of that JPanel...to add that JPanel i used bellow code
JFrame f = new JFrame();
JPanel panel = new JPanel();
f.getContentPane().add(BorderLayout.SOUTH, panel);

Hi
JFrame f = new JFrame();
JPanel panel = new JPanel();
// Add this line to ur code with ur requiredWidth and requiredHeight
panel.setPreferredSize(new Dimension(requiredWidth,requiredHeight));
f.getContentPane().add(BorderLayout.SOUTH, panel);
This should solve ur problem

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);

     public main(){}
     public static void main (String args[])

}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]

Problems with resizable container

Hi,
I have a resizable JPanel with cubes inside it.
The problem is when I resize the JPanel the cubes inside it gets resized only after I move the borders of the JPanel ~14 pixels...
The problem is in the X axis...
The Y axis "jumps" every ~5 pixels...
I need content of the JPanel also to resize every 1 pixel (so it would be on the borders of the JPanel)...
Any Ideas?

I guess that the only solution is NOT to use gridLayoutWell that would explain the behaviour. It would have been nice if that information was included in the original question. Thats why I always ask for a SSCCE, since you never no what information is importan or not.
All components in a GridLayout have the same size. So if you have a Grid with 10 component that is 400 pixels wide each component will be 40 pixels wide. As suggested above the size of each component will only be adjusted when you incread the width by 10 or more (since you have 10 components in each row).
Doing it manually would also be a pain. If you increase the width by 1 pixel you would only be able to increase the size of one component. Then if you increase it by one pixel again you can only change one component, so do you change the first one again or the second. So now you need an algorithm to determine which component gets the extra space.
I need content of the JPanel also to resize every 1 pixel (so it would be on the borders of the JPanel)...Don't know exactly what your layout is like, but maybe you could center the panel in the frame. That way as you change the size the "border" will change on both sides and it may not look as bad.
You can try using a BoxLayout. Components will grow as the size is increased but I think you might have problems with the first components always growing first.

Thread problem with displaying to JFrame :(

Hi everyone I have a problem, I have a JFrame which I use to submit a transaction. I am submitting a multiple number but would like to do so sequentially. SO for now i am starting one transaction thread, waiting for it to finish then starting the next etc.
My problem is that once a transaction is finished it will not print the msg to areaOutput untill all transactions have finished processing. But the call to system.out will print at the correct time.
I am sure i have missed a point just don't know what.
Thread m = new Thread(transactionN);
m.start();
try{
m.join();
areaOutput.append("Finshed thread #: " + threadNum + newline);
System.out.println("Thread done");
}catch(InterruptedException ie){
System.out.println("interrupted.");
threadNum ++;Thanks for any advice!!
luv M

Yes, like the previous poster said. If you are running your example code from the event thread (as response to some gui-interaction like pressing a button), you are blocking the event thread. The event thread is also the same thread that paints the screen. So nothing is painted until that piece of code is finished.

Problem with backspace on JFrame

Hello,
I have a problem on a JFrame. Indeed, I add a keyListener to the frame, but the "Bakcspace" don't work. There is anything when a I press on Backspace (with KeyTyped, KeyReleased and KeyPressed). All other keys are working.
Thanks.

the solution of the problem is :
Version note: This page reflects the focus API introduced in released 1.4. As of that release, the focus subsystem consumes focus traversal keys, such as Tab and Shift Tab. If you need to prevent the focus traversal keys from being consumed, you can call
component.setFocusTraversalKeysEnabled(false)
on the component that is firing the key events. Your program must then handle focus traversal on its own. Alternatively, you can use a KeyEventDispatcher to pre-listen to all key events. The focus page (in the Creating a GUI with JFC/Swing trail) has detailed information on the focus subsystem.

Problem with resizing the new Pages window

I can't get my Pages Window any smaller, it says (if I use Window Tidy for example) that the window size was restricted.
With the old Pages I used to have two Pages-windows open right next to each other, so I coul work on two documents at the same time. Now that i can't resize them anymore (only making them bigger is possible) they don't fit on the screen anymore.
Anyone having the same problem, maybe even a solution?
Thanks a lot in advance!

Posting here is only talking to fellow users.
Dump Pages 5 and go back to Pages '09, then give proper feedback on either Apple's website or the App Store.
The App Store is probably the best place as it is public and a bad review has more impact than private entreaties to Apple.

Problems with resizing video

I have a video which I would like to be able to play on my HTC Hero smartphone. The video size is 480 x 272 pixels. According to my friend, I have to resize it to fit in my smartphone device resolution, which is 3.2-inch TFT-LCD touch-sensitive screen with 320x480 HVGA resolution. However, I installed QuickTime Pro 7. I tried to resize it under Inspector Movies Property and I get an error saying that the timecode is invalid or something like that. I also noticed the file size would be in kilobytes than in megabytes. I tried extracting the video and editing from there but that did not work.
The problem is when I tried to play it on my smartphone, I cannot get the picture, I get a blank green coloured screen. The audio track work fine.

I have both Flip4Mac WMV and Perian installed. I do not have DIVX installed. You want me to convert the video? If so, which format? Alright then, I will send you a sample of the video.
If you have one of the "Studio" ($49 or more) level versions of Flip4Mac installed, I would recommend a WMV conversion since it is very standardized and specifically mentioned as being supported by your device. (Even if you only have the free player installed, you should be able to make up to a 30-second "demo" conversion for testing purposes.) Converting to Perian AVI could be iffy but your could try an MPEG4, H264, or H264 video with AAC, MP3, or WAV audio. (Official AVI support was dropped by originator a decade ago but Windows seem unwilling to "move on" to more modern file types.) The mere fact that WMV support is specifically mentioned leads me to think the multimedia player may be more "Windows" based than Mac based. Let us know how your test turns out as this may be an issue for other Mac users of this device.
I only have the free player and I am not very keen on paying $49 or more for these softwares. It is far fetch for me. I will make an attempt to try to convert the video and see what happen.
Erm...How do I do this? I had a look in System Preferences.

Problem with threads in JFrame

Hy everyone...i have a small problem when i try to insert clock in my JFrame , because all i get is an empty text field.
What i do is that i create inner class that extends Thread and implements Runnable , but i dont know ... i saw some examples on the intrnet...but they are all for Applets...
Does any one know how i can implement this in JFrame (JTextField in JFrame).
Actually any material on threads in JFrame or JPanel would be great....THNX.

For my original bad thread version, I have rewritten it mimicking javax.swing.Timer
implementation, reducing average CPU usage to 2 - 3%.
Will you try this:
import javax.swing.*;
import java.awt.*;
import java.text.*;
import java.util.*;

Problem with IconImage for JFrame

If I create an BufferedImage by ImageIO.read for example and then call getScaledInstance on this image and set the scaled Image to a JFrame as the IconImage (via setIconImage(Image image)), the application hangs.
Has anyone else this problem?

ok ok, i read it and now think that this is a sscce:
import java.awt.Image;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class Start
     public static void main(String[] args)
          final JFrame frame = new JFrame();
          final Image image, imageScaled;
          try
               image = ImageIO.read(new File("test.png"));
               imageScaled = image.getScaledInstance(8, 8, Image.SCALE_DEFAULT);
               frame.add(new JLabel(new ImageIcon(image)));
               //frame.setIconImage(image); works
               frame.setIconImage(imageScaled); // works not
               frame.pack();
               frame.setVisible(true);
          catch (IOException e)
               System.err.println(e.getMessage());
               e.printStackTrace(System.err);

Problem with display of JFrame

I have a run opperation in which i call a method that creates a j frame and displays it. all the j frame is used for is displaying the text "adding sample data...". It works fine when I have my main window open but when I have my layout editor open, the JFrame shows up grayed out. It clears after my samples are added. I have no Idea why it wont display correctly and I was just wondering if you had any ideas as to what whould cause this to happen. Thanks

I can't be sure without seeing your code, or without more information about what it is your doing, but the problem could be threading. Is the JFrame that's showing up grayed out just supposed to tell the user to basically "please wait while I do something", and then dissapear after it's done working? If so, you should probably use a JDialog. In any case, try wrapping the code that opens the window in this:
Thread opener new Thread(new Runnable(){
public void run()
// ... put your code that opens the window in here. such as myFrame.setVisible(true);
opener.start();

Problem with resizing canvas

PSE 8, Windows XP
Attempting to resize the canvas I entire a width and a lenght. I leave the position square in the middle. I click OK. The canvas extension appears only at the bottom of the photo, not all around as it does in PSE 3. I tried relative. Same result, just new canvas at the bottom. I checked Barbara Brundage's book and it should work the same as it does in PSE 3 but doesn't. I also went to PSE "Learn more about canvas size". It also shows that my canvas extensions should show all around. It also suggests that I should be able to choose a background color, but that option is grayed out for me.
I know I can just do what I want to do using PSE 3 which I kept on my computer for emergencies just like this, but I would like to solve the problem.
Can anyone tell me what I'm doing wrong?
Thanks. Eva

Eva,
Works fine in my PSE8 on Win XP. I see the following options (sorry, I only have a German version available):
The image centers just fine. Are you sure you're seing the entire image (ctrl-0)? What's the image format you're working on (PSD, JPG, 8-Bit, 16-Bit)?
