Set the JProgressBar size
Hi all,
I've added a JProgressBar in to a JFrame as follows.
progBar = new JProgressBar(0, 100);
progBar.setValue(0);
progBar.setBorderPainted(true);It's working fine. But I'm stuck on one thing. I cannot change the length of the JProgressBar. It's use a same length even I've change the length(width) of the JFrame. How can I change that.
I've read the doc, but didn't found the way to change it's size. Please help me.
ItsJava wrote:
So JProgressBar is a swing component and the JProgressClass inherit Component class. So all the methods in Component class methods are valid here. Am I right?Yes, you are right. The preferredSize, however, will only be honored if you're using a layout manager (which shows you are). And even with layout managers, it's only the "preferred" size, so it may not always be honored given the circumstances.

How do I set the Page size default in Adobe Reader using Window 8?
I need to set the page size everytime I go to print from my Adobe Reader in my windows 8. Is there a way to set the page I want letter (8.5 by 11) as a default? So I do not have to do this everytime I print something?
I can't help but wonder why Adobe doesn't respond to this - at this point there are 464 views of this item and still no answer. I have the same problem and it's a big irritation to have to set the duplex mode everytime I want to print!

How can I set the font size of a form field in the fdf file?
I need to dynamically set the font size of a field to accommodate text of varying length, automatic font size won't work in this case. It seems like this can be done in the FDF but I have tried several variants without success. Could someone help out with a real example of what the syntax in the fdf should look like.
I am using Acrobat Professional 8.1 but the created fdf will need to work with Reader also.I think that the font size has to be set in the form itself, not the FDF.

How do I set the default size of a new folder?
I have finder sized the way I want for existing folders and if I do Finder > New Finder Window. These preferrences, however, do not seem to apply to new folders. Everytime I create a new folder on my desktop, and open that folder for the first time, the window size is really small and the sidebar is narrow. This is incredibally annoying. How do I set the default size for all new folders? Is there a plist file I can edit to fix this? Or an AppleScript I can run automatically in the background that fixes this? I am running Mavericks 10.9.1.
If you use the Finder's New Finder Window command (command N) to create a new window, resize it, place it where you want, and set it for icon view or however you want it. Then close it. Closing it is what sets these as the default. That should become the default for every new Finder window you create using the new window command. But if you have lots of windows open at once and then close them, the last window you close will set a new default.
There are lots of utilities that control Windows - their size and placement. I use one called Moom but there are many more. -
The lead-in above pretty much states the problem. I am attempting to install Windows 7 from a disk, but that is not the issue. Boot Camp 5 just quits and reopens. I then repeat. Help.
I am about to run specialized GIS software that may or may not need the full machine resources. I am an attorney who uses QuickBooks for my accounting. The Mac version does not do as much as the Windows version. This is from both Apple and Quick Books professionals. I am using Parallels Desktop version 8 at this time. It does not support QuickBooks Windows version per Parallels. Any other questions? I am a highly competent PC user who is new to Macs. I am entitled to my own configuration choices. That said, I know when I need help which is now.
As to the free space issue I have 665.18 GB free space out of 749.3 GB on the drive. I am not trying to run the 32 bit version. I know that it requires the 64 bit version. Besides, it does not get that far in the process. As I said Boot Camp asssitant terminates unexpectedly as soon as you hit the continue button after setting the partition size. Therefore I conclude that it does not have a chance to see which version of Windows that I am using. I am using Windows 7 Ultimate 64 bit version in the virtual engine (to use Parallels speak), but again Boot Camp would not see that since it is not running. It can't run at the momenet because Apple just installed a new hard drive and I have just restored the data from TIme Machine and Parallels needs reactivated, which I have not done yet deliberatley. With all of this addtiional information do you have any further suggestions? Thanks for your time and interest my issue. -
Hi, I am using Indesign CS6, How to set the page size in Inches.
Hi, I am using Indesign CS6, How to set the page size in Inches.
All fields in InDesign can be entered in any measurement system. So, if you want to make an 8"x10" document and go to File>New Document and the window looks like this:
…you can type either 8 in or 8" into the Width field like this:
…and when you move to the next field, it will convert the eight inches into the equivalent number in the unit of measure that it is using at the moment, like this:
… (203.2 milimeters is the same as 8 inches). You can also enter a different measurement unit into other fields once the file is created, such as the width or height of a frame, or the position of an object in the X and Y coordinates.
If you would rather just work in inches instead of having to type the inches mark or abbreviation, go to InDesign>Preferences>General and select the Units & Increments tab. There you will see Ruler Units for Horizontal and Vertical at the top of the window. Set them to Inches and all of the fields will display in inches. If you do that to an open document, you will change the unit of measure for that document. If you do it while no documents are open, it will change the unit of measure for any new documents you create. To change the unit of measure for existing documents, you will have to open each and make the change. -
How to set the page size and the margins programatically
Hello,
I am working with crystal report XI Release2 and asp.net.
One of my report is having 4 graphs in a single report.In order to display all the graphs in one page i have set the paper size as A3.(Via Crysta report ->File->Page set up)
But the page size A3 is not provided by all printers.So problem comes when the application is diployed on a machine which does not support A3 Printer.All the graphs will not be shown on a single page.
Also Each and Every time ,when the application is diployed on a machine,user has to open the crystal report and adjust the page size accordingly to get all the reports on a single page.
This is a kind of usability issue also.
Is it possible to set the page size and the margins programatically say for eg 11 X 17.so that with out doing anything all the 4 graphs will get displayed on a single page ?
Please let me know if you require more information regarding this issue.
Thanks in advance.
smitha.Hi Ludek,
i could solve the issue by using the follwing code.
report = new ReportDocument();
PageMargins customPageMargin = report.PrintOptions.PageMargins;
report.PrintOptions.PaperOrientation = PaperOrientation.Portrait;
report.PrintOptions.PaperSize = PaperSize.Paper10x14;
customPageMargin.rightMargin = 1;
customPageMargin.topMargin = 0;
customPageMargin.bottomMargin = 0;
report.PrintOptions.ApplyPageMargins(customPageMargin);
Thanks for you help.

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 classReposted from

@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 to set the paper size when printing to postscript...
I need help in setting the paper size in the PrintPreference when using either the Postcript File or Adobe PDF printer to generate ps files.
Here's what I am doing (in c++) and I seem to be getting only 8.5x11 no matter the document page size:
LPDISPATCH p_Dispatch = Document.DocumentPreferences();
p_Dispatch = Document.DocumentPreferences();
if(p_Dispatch)
DocPreference docPreference(p_Dispatch);
pgOrientation = (idPrintPageOrientation)docPreference.get_PageOrientation();
pageW = docPreference.get_PageWidth();
pageH = docPreference.get_PageHeight();
paperSize = docPreference.get_PageSize();
docPreference.ReleaseDispatch();
p_Dispatch = Document.PrintPreferences();
if (p_Dispatch)
{ PrintPreference printPreference(p_Dispatch)printPreference.SetPrinter(idPostscriptFile);
printPreference.PrintFile(outfile);
printPreference.SetPaperSize(paperSize ); /*I have also tried idCustom but it crashes with invalid parameter for the object type.*/
printPreference.SetPaperWidth(pageW);
printPreference.SetPaperHeight(pageH);
VARIANT vprinterPresetType;
vprinterPresetType.vt = VT_I4;
vprinterPresetType.lVal = CInDesignApplication::idCustom;
Document.PrintOut(FALSE, vprinterPresetType);....
So how do i pas the document paper size to the print preset or preference?

Perumal SGood afternoon,
This works: f?p=1:#MYPAGENUMBERCOLUMN#::Session:Request:Debug:Clearcache:itemname:itemvalue:printerfreindly
It works very well. I have been struggling for a couple of hours trying to figure out how to calculate the page number I wanted to link to from a report column defined as a linked item. I ended up modifying my VIEW to include the page number for that particular type of data and use this technique to jump to the correct page.
Thanks for posting this. Nothing else seems to work.

Hi,
Can some one show me how to set the frame size in this program? History: I have created a window and added a button but its to small. So I want to increase the size of the frame to at least 600X400 pixel.
private static void showGUI() {
//Create and set up the window.
JFrame frame = new JFrame("ButtonDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Create and set up the content pane.
Main newContentPane = new Main();
newContentPane.setOpaque(true); //content panes must be opaque
frame.setContentPane(newContentPane);
//Display the window.
frame.pack();
frame.setVisible(true);
}It would be nice if you could show me how to do it.
Thank you very much for reading this.Challenger wrote:
Simply adding
frame.setSize(new Dimension(600,400));to the end of your code should work perfectly.Or, if you want to do it correctly, .setPreferredSize() on your frame before you .pack() it. The default layout manager for JFrame is BorderLayout, which uses the preferredSize of each component to calculate sizes during the .pack() call.
