Switching a panel to another panel in the same frame.Is there a better way?

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() instanceof toolButton){
            westPanel.remove(optionPanel);
            westPanel.setVisible(false);
            toolButton tb = (toolButton)e.getSource();
            optionPanel = tb.getPanel();
            westPanel.add(optionPanel);
            westPanel.setVisible(true);
    }This code above is what I used to execute when one of several JButtons is being pressed.
In this program, one of the JPanel will be automatically switched to another JPanel when you press the respective JButtons.
Here are my questions:
1. Right now, I use westPanel.setVisible(false) and then change some stuff and then invoke westPanel.setVisible(true) to make it visible again. Although this works, I have a feeling that this is not quite right. I feel that there should be some better way to do this, switching the panel and request the program to redraw the replacing JPanel. Is there a better way for this?
2. Most of the time, the JPanel changes the size according to the components on it. I have tried several LayoutManager, but it seems that those components have more priority. Is there a way to completely fix the JPanel so that they stay the same size?

Look into using a Card Layout rather than manually swapping the panels: http://java.sun.com/docs/books/tutorial/uiswing/layout/card.html

Adding items to the sidebar automatically - is there a better way?

I'm working on a way to automatically add a user's network home to the sidebar when they log in.
Currently, I've removed the local home from the sidebar in the user template, and the following runs at every login to check whether it is there and add if not:
(ignore the http link in line 2, forum doesn't like my code)
name="$(whoami)"
if [[ "$(defaults read com.apple.sidebarlists)" =~ "$name" ]]
then echo "true"
else
open /Volumes/MacHomes/$(whoami)
osascript -e 'tell application "System Events" to keystroke "t" using command down'
osascript -e 'tell application "System Events" to keystroke "w" using command down'
Which does the job, but I don't like the way that it has to open the folder in the GUI and can therefore be interrupted by an ill-timed click of the mouse. If possible, I'd prefer to run this without any visible element to the user. I'm also bothered by echoing a string that doesn't seem to go anywhere - to verify a condition and invoke else if necessary.
Can anyone offer any suggestions on how to improve this?
thanks
Chris

Tony,
Yes, but no!
The client's need is for an AFP based, per user, private storage area without using the functionality provided by OD but retaining the ability to manage with MCX - so it's a network home in all but name. Life is too short to waste my time explaining the politics... I will write it up and stick it on t'web when the project is done.
Essentially I have a collection of shell scripts that run at log in on the client. This part comprises a fairly minor piece that I would like to be a little more reliable and less intrusive to users in operation.

How to merge the Panel with another Panel to One Panel?

As Title!!

i will give it a shot. by no means do i say it is correct being a beginner myself
Panel aPanel = new Panel();
Panel anotherPanel = new Panel();
Panel mythirdPanel = new Panel();
aPanel.add(anotherPanel);
aPanel.add(myThirdPanel);
this should create one panel called aPanel with two panels inside - another Panel first, followed by mythirdPanel second. This should be in FlowLayout pattern as that is default unless specified.
That is my guess and my shot.

Two sliding panels/w tabs widgets on the same page?

I would like to use two of the same widget (Sliding Panels/w
tabs) on the same page.
How can I get two instances to function independently and not
break each other....?
I edited the sp_withTabs.js file by duplicating the first
section below copying it, modifying it, and then pasting it below
as the second section:
// Turn the slidingPanel region into a real sliding panel
widget.
Spry.$$("#slidingPanel").addClassName("SlidingPanels");
Spry.$$("#slidingPanel >
div").addClassName("SlidingPanelsContentGroup");
Spry.$$("#slidingPanel .SlidingPanelsContentGroup >
div").addClassName("SlidingPanelsContent");
sp2 = new Spry.Widget.SlidingPanels('slidingPanel');
// Turn the slidingPanel2 region into a real sliding panel
widget.
Spry.$$("#slidingPanel2").addClassName("SlidingPanels");
Spry.$$("#slidingPanel2 >
div").addClassName("SlidingPanelsContentGroup");
Spry.$$("#slidingPanel2 .SlidingPanelsContentGroup >
div").addClassName("SlidingPanelsContent");
sp2 = new Spry.Widget.SlidingPanels('slidingPanel2');
This actually gets the second instance to function properly,
but now the first instance is "frozen".

Chapman, i know its been a while
but where on the JS file is the part you changed?
I cant find that in mine
check out my page:
http://www.pupr.edu/department/industrial/students.asp
Im trying to do that same thing, but a sliding panel inside another one.
The one inside isnt being recognized as a slliding panel, im thinking its the same problem you were having.
If you need me to copy the .js file let me know!
This is working with the Spry Sliding Panels Widget

i have tried.. What happened to your shift key? Please apply it once at the start of every sentence, rather than those rare occasions you 'feel like it'. Adding an upper case letter to each sentence makes it easier for people to quickly scan the text, looking for ways to help. You would not want to make it harder for someone to help, would you?

Center a panel in another panel

Good day:
I am trying to center align (horizontal & vertical centering) a panel in another panel.
How would I go about doing this?
I have tried a few different layout managers, but they have not produced the results I am looking for.
The parent panel is fixed sized, but the child panel is dynamic.
Please help!!

Thank you for your post, I greatly appreciate it. However, I tried both of those methods, and my child JPanel is always being placed in the upper left corner of the parent JPanel.
Here is some code showing my initialization of the JPanel, and the adding of the child JPanel:
Creating the parent JPanel:
        imagePreview = new JPanel();
        imagePreview.setBackground(Color.white);
        imagePreview.setBorder(new LineBorder(Color.black,1,true));
        getContentPane().add(imagePreview);Adding the child JPanel
void displayThumbnail()
              wallpaperChanger.imagePreview.removeAll();
              wallpaperChanger.imagePreview.add(new viewer(THUMB_LOCATION));
              wallpaperChanger.imagePreview.repaint();
         }If it helps, the viewer class:
class viewer extends JPanel
     private Image image;
     public viewer(String fileName)
          Toolkit toolkit = Toolkit.getDefaultToolkit();
          image = toolkit.createImage(fileName);
          MediaTracker mediaTracker = new MediaTracker(this);
          mediaTracker.addImage(image, 0);
          try
               mediaTracker.waitForID(0);
          catch (InterruptedException ie)
               System.err.println(ie);
          setSize(image.getWidth(null), image.getHeight(null));
          //show();
     public void paint(Graphics graphics)
          graphics.drawImage(image, 0, 0, null);
}

How can I using tpcall from one service to another service in the same server

ok. However,
when I using tpcall from one service to another service, it's failed?
anybody can tell me why?Basically, tpcall:ing another service in the same server is a no-no, unless you
a) are running a multi-threaded server (requires TUXEDO 7 or newer + compilation
options) or
b) use tpacall() instead of tpcall() and specify the flag TPNOREPLY. This is probably
not what you want to accomplish, though.
The reason is that TUXEDO servers by default (and always in versions before 7)
are single-threaded. If service A and B both reside in server X, server X will
be busy taking care of the call to A. If A makes a call to B, the call will be
put on the queue to X, but X will not look at the queue until it is done with
A, which won't happen until B returns... deadlock!
You can play tricks with starting multiple instances of X, but in the end you
will always face a risk (something lika a race-condition) for a dead-lock.
Solution: Move service B to another server (usually quite easy) OR switch to multi-threading,
if that's possible. Just make sure all code your service calls is MT-safe as well...
thanks

How can I copy an audio effect from a clip and paste it to another clip in the same timiline...With FCPro 7 it was all so fast........

The advantage goes to FCP7 if you allow that it can copy and paste filters, audio and video, transformations, and other attributes separately.
You can do that in FCPX too, as all the things you cited are listed separately in the inspector.
Here's a little gotcha. Let's say you've color corrected a few clips and you've applied an effect to one and want to paste it the other clips. You switch off color correction and copy the clip. You select the other clips and paste effects. What do you think happens? The effect is applied, but the color correction is applied as well, only it's switched off as it was in the first clip, so all the color correction on the other clips is lost. Fun, eh?
I'll try to replicate your gotcha - but no, that doesn't sound like fun at all!

Load another sound in the same sound object

Hi,
I am loading a sound like this:
public var smallSound:Sound = new Sound();
public var trans1:SoundTransform = new SoundTransform(1, 0);
public var channel:SoundChannel = new SoundChannel();
smallSound.load(new URLRequest("firsttrack.mp3"));
channel=smallSound.play(0,1,trans1);
When an event occurs (button click actually) I would like to stop playing the first sound and playing another sound in the same object. So I try doing this:
smallSound.load(new URLRequest("secondtrack.mp3"));
channel=smallSound.play(0,1,trans1);
but it does not work. The first sound keeps playing. I havent understood something probably.. Can someone help me ??

ok, i solved my problem. It works like:
channel.stop();
smallSound = new Sound;
smallSound.load(new URLRequest("secondtrack.mp3"));
channel = new SoundChannel;
channel=smallSound.play(0,1,trans1);

Radio group in classic report based on another column on the same row.

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Application Express 4.1.0.00.32
How can I have a radio group column based on an LOV utilizing another column on the same row of the report?
For example: what if I had a survey application and depending on the likert scale that was assigned to the question there would be different possible answer choices:
Question 1 on row 1 of the report: The class instructor was friendly?
Likert scale choice is Agreement.
Choices on Radio Group: Strongly Agree, Agree, Undecided, Strongly Disagree
Question 2 on row 2 of the report: The class offered good materials?
Likert scale choice is Quality.
Choices on Radio Group: Excellent, Below Average, Average, Above Average, Excellent
The radio group can change per row depending on the Likert scale assigned to the question which is assigned to a different column on the row.
Can LOV utilize the column? :
SELECT scale_text
FROM scale_choices
WHERE scale_category_choice_id = 2 <<= this would be the Likert scale identifier
ORDER
BY display_order

Here is the answer:
APEX_ITEM.SELECT_LIST_FROM_QUERY(
p_idx IN NUMBER,
p_value IN VARCHAR2 DEFAULT NULL,
p_query IN VARCHAR2,
p_attributes IN VARCHAR2 DEFAULT NULL,
p_show_null IN VARCHAR2 DEFAULT 'YES',
p_null_value IN VARCHAR2 DEFAULT '%NULL%',
p_null_text IN VARCHAR2 DEFAULT '%',
p_item_id IN VARCHAR2 DEFAULT NULL,
p_item_label IN VARCHAR2 DEFAULT NULL,
p_show_extra IN VARCHAR2 DEFAULT 'YES')

Mountain Lion: Copying mailbox from one user to another user on the same mac

When I bought the mac I had only one email address. Since then I have accumulated 3 more addresses. I created another User on the same MAC to seperate the personal emails from the 3 new email addresses, that I use for business.
There are some mailboxes from the 1st account that has business information in them that I want to move to the 2nd User account (with the 3 e-mail addresses). I though that I could save them in the dropbox and then save them into the 2nd User accounts like I did with the documents and spreadsheets, but this does not work.
I really need to separate the Family Personal email information from the Busines Information and I do not want to just send lots and lots of emails to the accounts to get them there.
I am not using Cloud at the moment because it created some syncing issues. Because the 1st User Account and email account is synced with an iPad and iPhone that my wife uses with an Apple ID. The 2nd User (and 3 mail addresses) are synced with my iPhone and a separate Apple ID. We have separate ID's because she did not want my personal & business contacts seeping into the family email accounts
I know that this is long, but I wanted to provide as much information as possible, so that I can resolve this.
Thanks in Advance

I spent quite a few hours after this was posted trying to figure it out and I did.
Select Mailbox > Export Mailbox. This asks you a location to export the mailboxes to. It just uploads the exported mailboxes into Dropbox.
Then change the User that I want to import the mailboxes into. Select Import and select the location of where you placed the folder in Dropbox. This then imports the mailbox into a folder called Import. You then drag and drop the copied mailboxes from the Import folder to the folder in the structure you have. If you decide to delete the folders from the import folder list, do this. You can also delete the copied folders from Dropbox if you wish.
Took a while, but I got there and I'm happy now....
