Obtaining true size of a JFrame prior to making it visible

Is there a way to accomplish the following without making the frame visible first?
frame.setVisible(true);
Rectangle frameSize = frame.getBounds();
frame.setVisible(false);
The problem is that if I don't make the frame visible, then I get a height and width of 0 in frameSize.
Thanks in advance.

its very simple. you can specify the frame size by setSize() method or
directly you can call pack() method after adding all components. so after calling
pack() method you can get the frames width and height by getWidth() and getHeight() methods. these methods apply to all components and u can call
this method before calling setVisible(true).
i think this will solve ur problem.

How Do You Set the Maximum Size of a JFrame?

Can someone show me a quick example? The JFrame can be empty, I just want to know how to set it's maximum size. I tried using setMaximumSize() and it doesn't work for some reason but setMinimumSize() works fine.
I tried it using a BoxLayout and even using null as a layout manager and can't get it to work. I heard that the other layout managers don't allow you to set the maximum size of a JFrame so that is why I tried it with the layouts that I did.
I tried the following code (imported the necessary classes), but it does not work...
public class MyFrame extends JFrame
    public MyFrame()
        super("TestFrame");
        setLayout( new BoxLayout(getContentPane(), BoxLayout.X_AXIS) );
        setMaximumSize( new Dimension(400,200));
        setSize(300,150);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible( true );
}// end class

@OP:
When you repost a topic, please always provide a link to the previous post so people can check what suggestions were already offered (and didn't solve the problem).
Better still, give a short summary of the advice you have already tried.
I suggested setBackground(...) so you can see whether your MyFrame is actually occupying the entire real estate of the window. Looks as if trying it out (which I would have done for you if I'd been at home, where my JDK is) would have been too much effort for you.
I'm pretty much a novice in Swing, but I can tell you this: setLayout controls the layout of components added to the JFrame, not the layout of the frame with respect to its parent container.

How do you change the size of a JFrame?

I have some code using a jframe for an application creating buttons, but i want to also have some graphics in there, and I was wondering if there was a way to change the size of the jframe.

Use JFrame.setSize().
Check the JavaDocs for the method signatures.

How to set the cell size in a JFrame

Hello. Is there any way of setting the cell size in a JFrame. The reason why I want to set the cell size is that I want to be sure of their location that when I am placing components on the JFrame. So is there any way of setting the cell size beforehand. Also for the following code.
JFrame frame = new JFrame("Window");
frame.setSize(100,100);is the size 100 by 100 is he size of the cell?

Setting the size of a tablespace prior to its creation

Hi guys,
Oracle version: 10.2.0.x
OS: Windows 32bit
I was wondering if there are any 'conditions' in setting the intial size of a tablespace prior to its creation. This is because, one of our customers wants to export and import from one schema into another but set an initial size for a tablespace during its creation and prior to importing data into it, but we have a database wizard tool that creates the accounts/schemas by using the following underlying sql:-
CRETE TABLESPACE <tbl_name> datafile <path><datafile_name>.dbf SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M DEFAULT STORAGE (INITIAL 256 NEXT 256K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCREASE 0) ONLINE;
Under normal circumstances, what he would do is to use our wizard tool and create an account and then import data from an export dump.
But he wants to create a tablespace using a SQL something like:-
CRETE TABLESPACE <tbl_name> datafile <path><datafile_name>.dbf SIZE 2000M AUTOEXTEND ON NEXT 500M MAXSIZE 32000M DEFAULT STORAGE (INITIAL 256 NEXT 256K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCREASE 0) ONLINE;
He thinks this should be ok because his export dump would be on size 2GB and would want to import all of that 'at once' i.e. without actually using autoextend feature for the first 2GB.
Does this make any sense? Do you guys see any difference 'performance-wise' between the 2 create tablespace statements?
I think the second sql (with size 2000M initially) seems to be a more logical approach but I am not really sure of the implications going down the line performance-wise.
Any help/input much appreciated!
Thanks guys

1) Provide the facility in your tool to change the default size of datafiles and keep autoextend off.You won't believe it...we had this option in a previous version but now it isn't there anymore!
But why turning off AUTOEXTEND? I mean, our customers are not meant to modify anything in the database other than via using our software, hence we would want our customers to just use the software as it is but have their DBAs monitor the growth of any datafiles etc...
2) Let your tool do what it is doing and then manually increasing the size of the datafiles and making autoextend off once you have created the tablespace and before doing import. This can be done by your tool or loggin to the database.We could do this, but we don't want our customers to manually finger the database as they are/might not be Oracle-efficient and wouldn't want production systems to crash for the same reason.
Hence we could just give them the SQL to be replaced with the 'default' one and then create a tablespace via the tool which would create a tablespace with an initial size of 2GB+ and with greater autoextend facility (such as autoextend on 500M) rather than 100M so that there are fewer autoextends.
Also, in your point 2, are you saying to turn off autoextend only for the import and set it back on by alter tablespace....?
Thank you.

If you are on release 620, have a look at class CL_ABAP_MEMORY_UTILITES method GET_MEMORY_SIZE_OF_OBJECT. It will tell you how much memory is allocated and how much is actually used. Here is some sample code:
TABLES: sflight.
DATA: isflight TYPE TABLE OF sflight.
SELECT-OPTIONS: carrid FOR sflight-carrid.
SELECT * FROM sflight INTO TABLE isflight
        WHERE carrid IN carrid.
DATA: size1 TYPE abap_msize,
      size2 TYPE abap_msize,
      size3 TYPE abap_msize,
      size4 TYPE abap_msize,
      flag1 TYPE char128,
      size5 TYPE abap_msize,
      size6 TYPE abap_msize,
      flag2 TYPE char128,
      flag3 TYPE char128.
TRY.
CALL METHOD cl_abap_memory_utilities=>get_memory_size_of_object

      object                     = isflight

      bound_size_used            = size2

      referenced_size_used       = size4
      is_part_of_non_trivial_szk = flag1
      szk_size_alloc             = size5
      szk_size_used              = size6
      low_mem                    = flag2
      is_in_shared_memory        = flag3.
ENDTRY.
WRITE: / 'Size of Bound and Allocated Memory:', size1.
WRITE: / 'Size of Bound and Used Memory:', size2.

WRITE: / 'Flag, whether ONJECT is in the shared memory:', flag3.
If you aren't on 620 or don't need to be that precise, you might try the following:
DESCRIBE TABLE isflight LINES size1.
WRITE: / 'Number of Lines:', size1.
DATA: wa_sflight LIKE LINE OF isflight.
DESCRIBE FIELD wa_sflight LENGTH size2 IN BYTE MODE.
WRITE: / 'Size of one Line:', size2.
size3 = size1 * size2.
WRITE: / 'Total Size:', size3.
Please note that the addition IN BYTE MODE only works in 610 and higher. It isn't neccesary before that release. However it is important to get accurate resuls in an Unicode System.

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?

Possible to Restrict the Max Size of a JFrame?

I guess that the JFrame is my top level container, within which JTabbedPane is used. I wish to be able to not make the window maximizable. I remember how that could be done in JInternalFrame. When I looked up JInternalFrame, it looks like the boolean value for maximizable is specific to JInternalFrame and not inherited. Is there another way I can do that? When I messed around with setMaximumSize(), it doesn't stop the user from maximizing.
Also, if I want another container containing various components to obtain user input, which will pop up as a response to a button from the tab, is one container just as good as another, or is there a specific approach which is more friendly to this type of program?
Anyways, this is the bare bones of my code with all the bells and whistles and extra components cut out, in the event that it matters. ;o
public class TabTest extends JFrame
     public TabTest()
          JTabbedPane mainPane = new JTabbedPane();
          JPanel layer1PanelE = new JPanel();
          JPanel viewNclearPanel = new JPanel();
          layer1PanelE.add( viewNclearPanel );
          JPanel entryPanel = new JPanel();
          layer1PanelE.add( entryPanel );
          mainPane.addTab( "Tickets", null, layer1PanelE, "Edit new or existing tickets" );
          getContentPane().add( mainPane );
          setSize(850, 600);
          setVisible( true );
     public static void main ( String args[] )
          TabTest tabtest = new TabTest();
          tabtest.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

How to set a minimum size of a JFrame

hi freinds,
i have written a swing application which starts like this ,
public class workerclass extends JFrame implements ActionListener {
blah blah blah ..
now can you please tell me how to set a minimum size for this application once it starts so that user cant minimize it more than that minimum size.....
when i tried
setDefaultLookAndFeelDecorated(true);
it did my job by setting it to a particular size which wasnt minimizable, but this default look and feel looked ugly.
so i used system look and feel
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
but with this how do i set the minimum size..
please do help
and one thing more , like
in my main Method when i say
new workerclass().setSize(500,500); or say(100,100) or say(300,300)
new workerclass().setVisible(true);
the size (***,***) , doesnt reflect when my application starts, it always starts with some damn fixed size , what can be the issue .
waiting.........
Thanks

how do i set my Jrame to a minimum size so that
minimizing beyond that can be restrictedThis is what the code is all about

Setting the image size within a JFrame!

This is the code i have implemented
import javax.swing.*;
import java.awt.*;
class SampleJFrame extends JFrame
     JLabel l1;
     ImageIcon image;
     SampleJFrame()
          image=new ImageIcon("G:/java files1/images/aa.jpg");
          l1=new JLabel("DEDICATION",image,JLabel.RIGHT);
          l1.setSize(100,100);
          //this.setLayout(new FlowLayout(FlowLayout.RIGHT));
          this.add(l1);
public class JFrame2
     public static void main(String args[])
          SampleJFrame samplejframe=new SampleJFrame();
          samplejframe.setTitle("FRAMES WITH JLABELS WITH IMAGEICON");
          samplejframe.setSize(400,400);
          samplejframe.setVisible(true);
}When i run this the image occupies the entire JFrame.I want to resize it to a width of around 100,80 pixels.How can i do it?
I know when i draw a image without linking to a label i can use drawImage of Graphics class to set the size of the image.But in this case i am linking the image to the JLabel and it's occupying the entire screen and the text with the JLabel is thrown somewhere out.

Read it.Got a lot of info from that.But the trouble with mine is that i am linking the image to the JLabel and thats why i am unable to set its size because the image will be added to the JPanel when i add the JLabel to it?If i was directly printing the image i would have rather used Graphics.drawImage( ) where i can manually specify the width.

Cannot set the initial size of nested JFrame in NetBeans 5.5.

For some background; I'm trying to design a small configurable, multi-market clock for Traders of foreign currency. Several international market times will be displayed and each will change color as that market opens and closes. The user will be able to select specific foreign markets and configure several options such as color and size.
I was trying to use a JFrame for the initial window and an undecorated JFrame to hold the clocks and their labels. In the GUI builder for the initial JFrame, I dragged a JFrame and dropped it outside the original to add an (other Component). My problem is that I can't set the prefereedSize or the minimumSize properties for the nested JFrame. When I run the program, a button sets the second JFrame visible but at (0,0) size which when undecorated is invisible, and when decorated shows only the Min/Max/Close buttons. Am I just going about this all wrong or is this a bug
I am running Java Version 1.5.0 (build 1.5.0_08-b03)

I have tried to use several different components but I have not been able to get them to appear as a component, undocked from the main window.
Another idea that I tried was to have the whole program run from the same frame and then just set the window as undecorated and hide the menu bar. Unfortunately decorated state cannot be changed after it is displayable or packed. Besides that, how do you then make it moveable when there is no title bar? So many questions? Any other suggestions?
