Calendar in Swings !!
Is anybody aware of any util package for manipulating a calendar like object. It should display a proper calendar for a month with features like changing month and year, selecting any date by clicking on any day.
I have a date picker applet on a website, with code, which could very easily be converted to swing
http://michael-dunn.freeservers.com/java/DatePickerApplet.htm
the applet doesn't appear to display using the MS VM (probably because of the single swing component)

Thanks.

marcalenaTo create a month spinner
String[] months= {" Jan "," Feb "," Mar "," Apr "," May "," June "," July "," Aug ",
" Sep "," Oct "," Nov "," Dec "};
JSpinner monthSpinner = new JSpinner(new SpinnerListModel(months));You can do something simular for years or get more creative if you wish.
Cheers

I've written up a little clock widget that extends JLabel, so it should work with any Swing application. Hope it's not too long... Feel free to edit it. The enums are just for looks and can be replace with something else.
It just works off of a Timer every second to update the time in the label, and can display in various formats.

How to pop a virtual calendar with a click of button in swing applications
How to pop a virtual calendar with a click of button in swing applications
Does anyone knows how to pop up a virtual calendar in swing applications when there is a click of button. Do u have any components plug in tutorials or free java components download. Does java allows to used Microsoft calendar active x to plug into java applications. ThanksIf you want a simple date picker, try this one
http://forum.java.sun.com/thread.jspa?threadID=620699&messageID=3497753its a stand alone, but can be easily modified to include in a popup, and,
instead of displaying the date:
- passing the 'date picked' back to the calling object
- close the popup -
JCE requires: java.lang.RuntimePermission requires accessClassInPackage.sun.security.provider
I'm trying to use the JCE with JWS1.0.2. All I want to do is generate a KeyPair and I can NOT use a signed application. The code is:
public static KeyPair genDHKeyPair() throws Exception {
// properties...
DHParameterSpec dhSkipParamSpec;
dhSkipParamSpec = new DHParameterSpec(skip1024Modulus, skip1024Base);
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("DH");
keyPairGenerator.initialize(dhSkipParamSpec);
KeyPair keyPair = keyPairGenerator.generateKeyPair();
return keyPair;
I'm using JDK1.4. This code works fine outside of JWS.
If I call this code I get an exception that states I need the stated RuntimePermission. IMHO this is a bug because I should be able to make use of simple standard extension methods like this. Is getting an instance of a KeyPairGenerator and generating a key pair a security risk?
The fix for this should be a simple addition to the security policy for JWS which gives SUN javax.crypto code access to the appropriate RuntimePermission.
Can anyone think of a reason why NOT to do this?
Thank you.
BTW, here's the Exception you would get if you tried this:

The Exception i am having on the console is
java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.security.provider)
Note that I am NOT using JCE and that both netscape and IE browsers gave this error
Can somebody help me please?

JDk1.5.0beta3build58 security bug
JWS isn't working with third party look and feel implementations wrt the FileOpenService.
This seems to be a regression to 1.4.1 behaviour where I had to manually set the look and feel to the System LNF before trying to use the FileOpenService. I'm using JGoodies 1.2.2.
I do not see this with JDk1.5.0 beta2.

This caused regressions (by running Dialogs with differant Look and Feels in the same AppCOntext) such as the one in the TCK test ( 5060636 ), which were fixed in b57 by partially removing the original fix, so now the original bug is back.
I will re-open it.

UIManager ClassPath ignored? (access violation)
Appologies if this is a second post, but I do not believe my previous post worked. I do not see it in the list of topics...
I've encountered a serious problem: I can not use any 3rd party look and feel
implementations inside the Java Web Start secure sandbox. More specifically,
they work unless you use the FileOpenService or FileSaveService, which bring
up a JChooser with UI components that are in the wrong ClassLoader and cause
access violation exceptions.
Some code I have tried to (unsuccessfully) work around this problem:
// Attempt #1
ClassLoader jwsClassLoader = this.getClass().getClassLoader();
UIManager.put("ClassLoader", jwsClassLoader);
SlafLookAndFeel slaf = new SlafLookAndFeel("com.memoire.slaf.SlafLookAndFeel"); UIManager.setLookAndFeel(slaf);
This brings up the SLAF look and feel for everything but the FileOpenService.
Exception pasted below.
// Attempt #2
// After executing the above code, I also run this:
Hashtable tb = UIManager.getDefaults();
tb.put("ClassLoader", jwsClassLoader);
Enumeration e = tb.keys();
while (e.hasMoreElements()) {
Object obj = e.nextElement();
if (! (obj instanceof String))
continue;
String k = (String)obj;
if (k.endsWith("UI")) {
Class uic;
try {
uic = jwsClassLoader.loadClass(tb.get(k).toString());
} catch(Exception ex) {
// classnotfound...
continue;
tb.put(uic.getName(), uic);
Again, this does not help.
// Attempt #3
In Sun bug:4155617 the username 'awiner' posted a message that contained
some code to register your own ClassInstantiator (implements UIDefaults.LazyValue)
I would like to try this, but I do not know how to use the code presented.
I think it needs to be integrated within the Look and Feel code?

How can I code around this: RuntimePermission accessClassInPackage
(JDK1.4)
I'm using JCE in Java Web Start without this permission.
The code I'm using very simple:
DHParameterSpec dhSkipParamSpec;
dhSkipParamSpec = new DHParameterSpec(skip1024Modulus, skip1024Base);
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("DH");
keyPairGenerator.initialize(dhSkipParamSpec);
KeyPair keyPair = keyPairGenerator.generateKeyPair();
This code tries to access the code in a sun.security.provider which throws the stack trace below.
Of course, the code works without a SecurityManager. I'm likely fubar'd with JWS and above code.
Is my only option to investigate complete JCE rewrites like IAIK so I can make it part of my classpath (and security policy)??
Thank you.

Hi guys,
I need your help on a swing question.
I did many researches on the web but I didn't find any useful result.
Does exists some good free library for swing project?
Is there a free library for use advances textbox, calendar or other controls?
I mean, to make a comparison, something like good primafaces for web..
I sayd it cause I need to develop a appointment calendar in swing and I can't find anything more than standard calendar...
Do you have some link for me?
Thanks,
RegardsI thought I remember Kleopatra posting a Calendar widget for trial on the old Sun forums for the SwingX project.
I couldn't find it on their new website ( http://swinglabs.org/index.jsp ) though, since the JNLP demos weren't working for me.
Perhaps she can chime in to shed some light on its status. -
Searching a calendar swing component
Hello friends.
I'm looking for a calendar swing component, to make a schedule aplication (like Outlook).
I found "Mig Java Calendar" (http://www.migcalendar.com/index.php) but it isn't free, i need one like this free.
Do you know someone free?
Thank you.And if you think, as I do, that a date picker is
standard component and should be part of the jdk,
please vote here:

Hi,
Commonly enough; in my Swing app I need to display a calendar of dates.
I've been looking for third-party components (both free and commercial) as building my own seems daft really. However, most seem to be primarily "date pickers". What I need is something that indicates "busy days" (days with an entry booked on them) on the calendar display.
Can anyone point me to any good ones? I see there are loads out there. I'd happily take a good/pretty "date picker" and add to it if I can get the source code.
I've looked at so many through Google that I don't know which to invest my time - and potentially money - in.
Many thanksis there a calendar component in the jdk or an open source component?The forum has a search facility. Its really not that difficult to think of search words. The words in your subject title will do just fine.

Does Swing have a calendar widget that can be connected to a JFormattedText
Does Swing have a calendar widget that can be connected to a JFormattedTextField? I want to be able to either type a date into the field, or click an arrow and choose the date from the widget.
Thanks,
Matthttp://freshmeat.net/projects/jcalendar4swing/
http://sourceforge.net/projects/jcalendar
You will have to perform the linking to your text field yourself. -
I've implemented this into my application:
http://forms.pjc.bean.over-blog.com/article-14848846.html
Now suddenly the Calendar is no longer showing up on my canvas. I must have changed something that has stopped it from popping up? I click the button and the code fires without error, but no calendar is displayed. Has anyone else experienced this? Do you have any suggestions?
I have both the Calendar push button and the Bean object on seperate, non-base table control block and the item it populates is on my main base-table canvas.
The push button code is:
go_item('induction_info.drop_dt');
Set_Custom_Property('CTRL.BEAN',1, 'SET_PROPERTY','title,Drop Date');
Set_Custom_Property('CTRL.BEAN',1, 'SHOW_CALENDAR','50,50');
Thanks in advance.In the event anyone runs into this issue going forward...
I had changed the 'Database Block Property' of my control block from 'Yes' to 'No' at some point. I changed it back to 'Yes' and now the calendar is displaying again. Especially strange to me in that my control block is does not specify a base table and no items on the control block are base-table items. -
Is there a way to add event details using a calendar object vs. those dumb field entry boxes?
I have switched from PC to Mac over a year and a half ago, and have been plagued with the "dumb" date entry boxes in iCal and now Reminders on the mac. For one, they don't show you the DAY OF WEEK for an event, it assumes you are parked on that day, but of course reality sets in and causes constant date changes for events. Picking a date in the future would be much more helpful if Apple followed some usability norms in iCal. For instance, if you are booking a flight online, those helpful little calendar objects pop up, and further, they are smart about "end dates and times" for events, knowing it can't be earlier than the start date. Apple iCal unfortunately always thinks you are creating an ALL DAY event, and when you change the start time, it creates the end time for the next day. Not very smart. Or is it me that is not very smart for constantly hawking every little data entry field for correctness. Why, oh why dear lord has Apple not given some usability attention to iCal on the mac??? At least match the interface of the iPhone with a nice little slot machine rolling control.
Is there an add in?
Is there hope that Apple will ever fix its lagging Mail and iCal apps on the Mac?
Please advise. Or just offer a kind word of consolation if there is no hope for a better interface.In the future, Swing related questions should be posted in the Swing forum.
The code you posted is of little use since it uses custom classes so we can't see the behaviour of your code.
In general if you add a component to a Container at run time then you just use
container.revalidate()
This will invoke the LayoutManager and repaint the components in the container based on the new layout. -
How to create the digital clock in java swing application ?
I want to create the running digital clock in my java swing application. Can someone throw some light on this how to do this ? Or If someone has done it then can someone pl. paste the code ?
Thanks.hi prah_Rich,
I have created a digital clock you can use. You will most likely have to change some things to use it in another app although that shouldn't be too hard. A least it can give you some ideas on how to create one of your own. There are three classes.One that creates the numbers. a gui class and frame class.
cheers:)
