Give static size to Jcomponents

Hi,
I have problem to fix the size of my JLabel, JComboBox and JCheckBox.
Those components are included in a JPanel which is included in a GridLayout component.
However I used the following propertie :
tabComboBox.setPreferredSize(new Dimension(80, 5));
If I run my application, this size isn't set.
It depends of the "JPanel", I think ?
If somebody has an idea how to do that ?
Thanks.

And I saw that "GridBagLayout" doesn't offer the same possibility ?Sure it does. You just need to become familiar with the various constraints. Check out the tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/layout/visual.html]How to Use Layout Managers.
Or, you can always mix and match LayoutManagers. Maybe something like:
JPanel main = new JPanel( new GridLayout(0, 1) );
for (each row)
JPanel row = new JPanel();
row.add(label);
row.add(comboBox);
row.add(checkBox);
main.add(row);

Time machine gives wrong size in lion 10.7.4

The hard drive has a total size of 250 gb but time machine gives wrong size of 750 gb??

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select "system.log" from the file list. Enter "backupd" (without the quotes) in the String Matching text field. Post the messages from the last backup, beginning with "Starting standard backup."
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Do not post many repetitions of the same message.

N73 Gives Static on Startup.

Yes. Just like the title says. When i boot up my N73 it just gives me static of al different colours. The thing though is the phone works fine i can ring people and what not. But cant read or see anything. I took some photos for the helping you solve this.
This is the screen where it just shows the word "nokia"
http://i42.tinypic.com/2s8g4dl.jpg
and this is the main menu/home page
http://i42.tinypic.com/2943rb4.jpg
The first time i booted it up it worked flawlessley but i dropped it with the back cover off whilst it was on charge and the battery came out.
From my research over google it has lead me to find that it is a fauly screen and needs to be replaced. I need to know what it is to speed up the repair process. For i bought this second hand off E-bay. This is the quote " WARRANTY WILL COVER THE COSTS OF LABOUR & PARTS" I hope everyone can help me because i only got the phone yesterday.
Thanks in advance

Thank you for the reply.I dont really think that it has anything to do with any data because i havnt used any of the phone memory and installed everything to my miniSD. I updated the firmware also. Still gave me the screen. But on a lighter note i sent the phone back to the seller today. They claim that their "technician" will have a look at the phone and run a routine check through everything that came with it and if they find a fault, they will repair it for free. Im hoping that this is a genuine guarentee because i would be out 40 bucks getting a new screen.
Thanks for the reply

MF8580 prints two pages, then gives paper size and settings mismatch error. Help!

Hello, I have been dealing with this problem for weeks now. When i called support, they told me it was my computer, that it was "running slow" and that i need to pay for their service - that fixing errors in my registry would fix the problem. However, i have my own registry cleaner and that isnt the problem. Every time i print something, the printer will print the first two pages, and then beep, giving me the error "paper size and settings mismatch Drawer 1" - I have everything set to letter - in the driver, on the printer, etc. I do nto understand why it prints two pages and then tells me there is a mismatch. If i open and close the drawer, it will print the second page again and then the third page, and give me the same error again. rinse and repeat. This also happens when multiple documents are spooled. I send three - one page documents, it will print the first and second, give me the error, i open and close the paper drawer 1, then it prints document two and three - then gives me the same error - i open and reclose and it prints the thrid document... I am just baffeled.

Possibel to give stage size as parameter in html ?

I know Stage size width and length are read only, but i think
to remember that it was possible to change it the moment you call
it from html ?
No ?

Just to add my 2 pence to what was already said..
One of the rules for Robust Software is not to rely on implicit data type conversions to make things work. And that is what you are doing.
The parameter is a date type. You pass a string value. Oracle now attempts to implicitly convert that string to a date.
Sometimes it will work. Sometimes not. Why? Because it depends on things like the NLS settings of that particular sessions that governs implicit data conversions. Like what format must a string be in to be successfully converted into a date?
And relying on this, is bloody dangerous. Consider the string '12/01/2008'. One session has a NLS date format of 'dd/mm/yyyy' and the other the format 'mm/dd/yyyy'.
The result will be a successfully converted date.. but the WRONG date. And slowly and silently (no errors) your application starts to corrupt data in the database, because your code relies on implicit data type conversions.
General rule: Implicit data type conversions are EVIL! Do not use!!

Landscape Orientation: [view bounds] gives wrong sizes?

Hi
Getting a view's bounds rect while in Landscape Mode returns the wrong sizes:
Starting from a new UIView Template Project, I'm adding a single UIView to the ViewController in Interface Builder (in Landscape Mode) and setting the view size to width=400, height=200;
However when I add a breakpoint in the ViewController (at viewDidAppear), the sizes are w=220, h=380!
(Even though the view clearly is correct on the screen)
In myViewController.m I've set:
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); // home button on right
In myAppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
application.statusBarOrientation = UIInterfaceOrientationLandscapeRight; //home on right
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
and in the info.plist I've set: Initial interface orientation = Landscape (right home button)
I'm not trying to rotate the view with the iPhone, it is meant to be fixed in Landscape only.
Is there a workaround for this? I need to create some CALayers dependent on the correct view size.
Thanks
Steve

K7T 266 Pro2 RU; Raid gives wrong size on HDD

Hi!
I've got a K7T266 Pro2 RU, and trying to set up two Samsung 160GB in Stripe mode (2+0), creating an array of 320GB.
The Promise bios displays one array of 320GB (as I set it up), but when I try to install WinXP, it only comes up with a volume of about 260GB...
There should not be any limitations on terms of WinXP/NTFS, so therefore I suspect that the Promise driver gives false information to WinXP, showing what most likely is a raid containing two 130GB disks.
Has anyone experienced the same problem?
FYI: I striped two 40GB IBM's earlier, creating an array of 80GB - worked like a charm. Also - the jumper settings on the Samsung disks are correct... I have even tried with Promise's own drivers for this controller, but it won't work. I guess MSI has added too much change for its OEM drivers :-(
I would greatly appreciate any help!!

How do I find out a file's particular size?

Good Evening,
I am looking for assistance with figuring out a file's particular size within a group of files.
If I have one large directory and I am looking to find out what the smallest file in that directory is, how would I go about doing it?
Also, how would I figure out when the file was created on the system or particular hard drive such as a network attached storage device?
Thank you!

While command + i (or the Finder Information icon) would give you the file size, that would require a one-by-one approach. Perhaps quicker would be using a utility like "What Size" that will list Folders/files and give the size of each.

Scanning size with HP 2570

I've been having a problem scanning documents with my HP 2570 all-in-one printer-scanner as far as the size goes.
The window that gives the size I want it to scan in as says it's 100 per cent, yet it scans in almost 3 times bigger. When printing what I scanned in, if I set the print size to 36 percent it will print the original size.
Does anyone have any idea what may be causing the problem??
Thanks,
Barry

Welcome to the HP Community Forum.
I don't know if this will fix the problem, but one of the first things you can do is to take out the old software and install a fresh copy and see if that takes care of it. Sometimes this is all that is needed.
Out with the Old:
If you are using a USB cable, be sure to disconnect the cable before starting this procedure.
Control Panel > set icon view > Programs and Features >
Scroll down, find the Printer program > Right-Click on the program > Uninstall
Repeat these steps for each occurrence of your printer's name until none remain in the list.
Restart / Reboot the computer and log in
In with the New:
Install Full Feature Software – Printer
There are more Troubleshooting tips in your printer's Support pages that may provide some additional help, too.

How can I change the size of a logo?

I started making a logo in Illustrator. At the beginning I had to give the size in points. Now I'm finished and I want to change it. How can I do this?

Pieter,
Always keep the original artwork, so make changes to a copy. In this case you should keep them in separate documents.
If you wish to have the size(s) changed so that everything has the same dimensions in the other unit, you may use the conversion factors, 1 inch = 72 points, 1 mm = 1/25.4 inch, etc.
So if you wish to have the same dimensions in mm as you had in points, to do it with full(est possible) accuracy you need to select everything, then with Scale Strokes and Effects ticked in the Transform palette flyout:
1) Add *72 in the W field and press Ctrl/CmdEnter (to have the same dimensions in inches);
2) Add /25.4 in the W field and press Ctrl/CmdEnter (to have the same dimensions in mm).
Remember to untick Scale Strokes and Effects if unneeded afterwards.
You can check the dimensions of the original and converted artwork against each other when you have them in the corresponding File>Document Setup>Units.

How to find the Size of a Folder &also list the sub folder and files in it

In my program I want to know the size of a folder . The input given is the path of the folder and the ouptut should be the list of files and subfolders with their size. What is the function we have to use for this?
Thank you

class: file
method: listFiles() - list all files of the dir referenced by the file object
method: length() - give the size of the file referenced by the file object ; you have to call this method on all file of the dir to make the sum and have the dir size

Get the file size of a file on the server.

okay.. for my download manager i need to get the file size. I tried using the available method of inputstream, and the getContentLength() of URLConnection, which worked but only for webpages. so does anyone know how to do this? Sun does it in SDM, but i dont think the source is included. ill download it again and check.
thanks.

content-length is not guaranteed to be anythingi dont think so. correct me if i am wrong..
http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#s
c4.4 states -
" When a Content-Length is given in a message where a
message-body is allowed, its field value MUST exactly
match the number of OCTETs in the message-body.
HTTP/1.1 user agents MUST notify the user when an
invalid length is received and detected."
this sort of guarantees that if a file is being
downloaded the content-length gives the size of the
file. i am able to confirm this by sniffing the
traffic of my download manager.This is only guaranteed if the content length field is present. :-)
However, looking two paragraphs up:
'All HTTP/1.1 applications that receive entities MUST accept the "chunked" transfer-coding (section 3.6), thus allowing this mechanism to be used for messages when the message length cannot be determined in advance.'
There is mechanism built in for cases where the size cannot be determined.

Problems with size with JList

Hi...I have made an application that has a JTable with listeners on. When you press a cell the information in the cell appears in the Jlist.
When you first run the program you see the JTable and the empty JList. We have set a preferredSize on the JList, but when we press the different cells in the JTable (even though it has no information under it), the size sometimes changes. The JList gets bigger (even though its empty), and when we press a nother cell again it goes back to normal size.
Anyone has any idea why the size changes? How can you set a static size, or a none altering size??

Set minimumSize and maximumSize for the list and for the viewport of the jscrollpane (if any) as well.

Report Size to fit Chart Size

Using the dynamic width and dynamic height properties of a chart I will change the size of the chart dynamically.
However, when exporting the chart to an image I want it to export at the chart size and not be restricted to the static size of the page.
Any way to do this ?

Hi St33ln,
If I understand correctly, you want to make the size of report to fit the size of chart, so the chart can be fully displayed after export the report to an image. Based on my research, I find that PageSize property is a static value. The page size does not
grow or shrink to accommodate the contents of the report body. If you want the report to appear on a single page, all the content within the report body must fit on the physical page.
So in your scenario, I couldn’t find an appropriate method to make the report size automatically change to fit the chart size. This is by design. As a workaround, I suggest that you can change the size of report to an appropriate value based on the chart
size you may select.
Thank you for your understanding.
Regards,
Katherine Xiong
