Have to resize frame

I have made a GUI application which consist of many JPanels and classes that extends JPanels. However, when I do stuff, I have to resize my frame to see that anything has changed.
What is the cause of this and more importantly how do I fix it?
I am not sure wheter I should use, validate(), repaint() or updateUI(). But even so it doesnt seem to work. Have I just missplaced the call to one of them?

What is the cause of thisThe LayoutManager doesn't know you've made changes.
Invoke the layout manager. Generally the format of your code should be:
panel.remove(...);
panel.add(...);
panel.revalidate();
panel.repaint(); or updateUI(). Never use that. Did you read the API? That is for a LAF change.
Maybe you should be using a [Card Layout|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html].
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], 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.

Resize frame

I use NetBeans 5.5
With help of GUI Builder I made a JFrame Form.
Then, I add a class which extends JPanel to my Form.
This Class has Panel with JTable and a panel with some buttons.
The problem is:
Frame doesn't resize after my class adding.
User sees half om my JTable. So he has to resize frame window manually.
Is there any way to get "real" size of my frame (including added components) and resize frame to "real" size?

As i have wrote before, I think problem is in the interaction between GUI Builder designed components and manually wrote components

Why does FireFox open as a very small box in the top l/h corner and i have to resize it every time

Why does FireFox open as a very small box in the top l/h corner and i have to resize it every time this only occurs on the initial opening up of F/Fx after boot-up

Open the system menu via Alt+Space and see if you can resize that window. 
If that works then close Firefox (File > Exit/Quit) to save that setting.

Need to global find and scale and resize frame on a linked graphic

I have a whole set of files that contain multiple instances of an icon set (placed AI file). All of these are formatted to flow in the text as anchored objects with various object styles. I need to make sure that all instances of the placed AI icons are scaled to 30% and that their frames are fit to content. I have a LOT of files and each one has at least 20 of these icons. I thought the Object find and replace would help, but unfortunately it will not let you search for links, and while I can search for the object styles, there's no option to change scale and the fit content options does not have the "fit frame to content" (and doesn't work anyway from the few tests I ran using "fit content proportionally").
Does anyone have any ideas for how I can fix this globally in nearly 500 documents without having to manually select each icon and change the scale and apply the fit frame to content? I've done a handful of files this way, and it's VERY time consuming.

First make sure this works by duplicating a file and testing.
Make 1 image the size you need it
Grep search for
Find
~a
Change to
~C
if that doesn't work then try ~c (lower case) I can't remember how that works
If it does work - then you can open 2 documents and choose "All Documents" in the Search field.
If it's fine on 2 docs - then I'd say go ahead and do the rest.
I stress to please use a duplicate set of files in case things go bad.

Why the images have missed their frame stroke, once online?

I am working on my new website on iweb 09, and published a test, it looks very nice.
The only thing I don´t understand is why the images have missed their frame stroke, once online.
What´s wrong, any idea?
On iWeb, Inspector/Graphic/Stroke/Picture Frame

It appears that the Scrips folder for you site has not been uploaded or not uploaded fully. There are two files, iWebImage.js and iWebSite.js. Try the following:
1 - do a File->Publish Entire Site and see if the site works as intended. You may have to do a refresh on the pages a couple of times.
2 - next, in needed, publish your site to a folder on your hard drive. Mount your iDisk and go to the iDisk/Web/Sites/arkimo folder. Drag the two files above from the Scripts folder on your computer into the Scripts folder on the iDisk Then try the site again.
Part of the problem is the server, some files not loading the first time, and part is the missing js files in the Scripts folder.

I use a macbook pro retina. I use a 32 in. monitor and use it full screen. I size the screen manually. Since i upgraded to maverick, I have to resize the screen each time I change windows.Before the upgrade the screen stayed where I put it.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Captivate 5 - issue with editing imported PowerPoints that have been resized

I'm having an issue with editing PowerPoint files that have been imported into Captivate 5 when they have been resized within the Captivate project after the initial import.
1. I import a PowerPoint presentation into 800x600 dimension.
2. I resize the project to 900x600 by not locking the aspect ratio and selecting to position to the top right so there is a 100 pixel strip to the left of the slide that we use for navigation buttons and other info.
3. If I need to make a change to a PowerPoint, I select Edit > Edit with Microsoft PowerPoint > Edit Slide (or Edit Presentation).
4. The slide opens in PowerPoint and I make the changes and click Save.
5. When the slide is imported back into Captivate, it is stretched and resized to not fit either 800x600 or 900x600, but something in between. This did not happen in Captivate 4 - the slide would retain the 800x600 dimension slid over to the right with no issues.
Are there any settings that can be done to ensure the edited slides will import back into the project with the correctly sized dimensions for the current project?

Hi there
I agree that it would be nice to see a notification. You know, Captivate offers a special area for notifications that appear when you open it. I'm stymied as to why Adobe doesn't use this area for making such announcements.
Cheers... Rick

Possible to have UILabel auto-resize frame?

I'd like to display a block of text, but it's not known at compile time. I know I can set the numberOfLines to 0 for the UILabel and it will automatically use as many lines as it needs, but what about the frame? I want to display content immediately beneath it and I don't know how tall of a rect to provide when I create the UILabel initWithFrame.
Is there something like UILabel.resizeFrameHeightBasedOnTextWrapping?
I've checked the docs and can't find anything like this.
Thanks

Solved this myself. sizeWithFont() message series should do the trick.

I have a resize problem and a question about the reset button.

What I am trying to do is clear the list, I can clear the name but I want the list to have no selections instead of going back to default. Also I wanted to know if there is anyway to resize the list windows because one of my list windows is off on my maac computer but not on a regular pc.

How to have automatic resizing of container when JInternalFrame resizes?

Is there a good way for the automatic resizing of its container when a JInternalFrame is resized?
The intent is to have the JTree below, automatically resize. for example,
if you type newlines into the JTextArea contained in JInternalFrames.
(Tried adding the JInternalFrames to a JDesktopPane, but it did not display them. I wonder if it is inefficient to have a JDesktopPane for each tree node).
Is there any way to know if a JInternalFrame is resizing? Perhaps then one can reload the tree as:
treeModel.reload()thanks,

I think this does what you want; it's basically the same technique as we used before.
It also suffers from an interesting bug: if I type in the text area inside the internal frame, the editor resizes nicely
with the node below it staying visible; if I type in the text area next to the panel, the editor will resize over the node
below it. I didn't dig into it further to see the cause.

JTable have no resize cursor under a JLayeredPane

Hi,
i have over my JScrollPane a JLayeredPane to show infotext.
When the JLayeredPane is over the JScrollpane you can resize the column but the JTable show no resize Cursor.
Does anybody know why?
import java.awt.Component;
import java.awt.Dimension;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JLayeredPane;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.WindowConstants;
import javax.swing.table.DefaultTableModel;
public class NoResizeCursorDemo extends JFrame
public NoResizeCursorDemo()
    JTable table = new JTable( new DefaultTableModel( new String[]{ "aaa", "bbb" }, 10 ) );
    JScrollPane scrollPane = new JScrollPane( table );
    InfoLayer layer = new InfoLayer( scrollPane );
    add( layer );
public static void main( String[] args )
    NoResizeCursorDemo frame = new NoResizeCursorDemo();
    frame.setDefaultCloseOperation( WindowConstants.EXIT_ON_CLOSE );
    frame.pack();
    frame.setVisible( true );
class InfoLayer extends JLayeredPane
    private final JComponent wrappedComponent;
    public InfoLayer( JComponent wrappedComponent )
      this.wrappedComponent = wrappedComponent;
      setLayout( null );
      add( wrappedComponent, JLayeredPane.DEFAULT_LAYER );
      setInfoText();
    private void setInfoText()
      add( new JLabel( "Info......" ), JLayeredPane.POPUP_LAYER );
      revalidate();
    @Override
    public Dimension getPreferredSize()
      return wrappedComponent.getPreferredSize();
    @Override
    public void doLayout()
      Dimension size = getSize();
      Component layers[] = getComponents();
      for ( Component layer : layers )
        layer.setBounds( 0, 0, size.width, size.height );
}Thanks

Hi,
I had almost the same problem with JTable and JSplitPane, the components worked fine, but cursor did not change when require.
I already had in place mouse events dispatching in my top layer. It passed all events to the components underneath (see example in [Glass Pane Demo Project|http://java.sun.com/docs/books/tutorial/uiswing/examples/components/GlassPaneDemoProject/src/components/GlassPaneDemo.java]; in my case the listener was the content panel of the top layer).
And now here is the trick around the cursor. Within the custom dispatch method I've called the following:
this.setCursor(comp.getCursor());
where "this" is the content panel of the layer and comp is the component where mouse event passed to.
Hope that helps!
Regards,
Sergey

Rescale GUI-Components on resizeing frame?

Hello,
how do I have to implement rescaling GUI-components when a frame (JFrame) is resized by a user on runtime?
Should I have to use the observer-observable-pattern?
thanx

If you've got a layout manager then its automatic otherwise add a WindowListener to capture the resize event then resize them yourself.
