Problem with JComboBox in a fixed JToolBar

Hi,
I've created a JComboBox in a JToolBar that contains all available fonts. When I click on the drop down arrow I only see the first font and a small part of the second. The JComboBox is dropped down in fact just as far as the border of the JToolbar. All the rest isn't visible to me; it seems that they are behind the other components of my JApplet. However, if I move the JToolBar from it's position (as it's a floatable component), there's no problem at all. So I'm wondering why I can't see everything when the JToolBar is docked.... Can anyone help me?
Thanks in advance!!

it seems that they are behind the other components of my JApplet.Sounds like you are mixing AWT components with your Swing application. Make sure you are using JPanel, JButton ... and not Panel, Button....

Strange problem with JComboBox

I am having a strange problem with JComboBox, I created a method as a JComboBox factory which returns a JComboBox filled with items. the method works fine and I can see the items in the JComboBox. The problem is when I try using the method myCombo.SelectedItem(String item); the object myCombo does not set the selected item, it just leaves the item blank (or unselected).
//This method build a JComboBox
public javax.swing.JComboBox makeJComboBox(String[] items) {
javax.swing.JComboBox myComboBox = new javax.swing.JComboBox();
for (int index=0;index<items.length;index++){
myComboBox.addItem(makeObj(items[index]));
return myComboBox;
public Object makeObj(final String item) {
return new Object() {
public String toString() {
return item;
}

Couple of better ways to populate a combo with items-
public javax.swing.JComboBox makeJComboBox(String[]items) {
javax.swing.ComboBoxModel cbModel = new DefaultComboBoxModel(items);
javax.swing.JComboBox myComboBox = new javax.swing.JComboBox(cbModel);
return myComboBox;
}OR
public javax.swing.JComboBox makeJComboBox(String[]items) {
return new javax.swing.JComboBox(items);

Are the problems with Compressor's encoding fixed yet?

Sorry for the slightly vague title but I only use compressor once a year basically, which is after the production of a Christmas show I produce. Last year I upgraded ot Final Cut Studio to do the DVD and got caught out. I encoded using what I thought was the best setting (2 pass variable bit rate) and got jittery encoding. After investigating on this very forum, I found lots of comments about known problems with Compressor's encoding in this setting and ended up re encoding using one pass which was "ok".
I'd rather do the best job I can so the basic question is, "is it fixed yet". Keeping in mind I understand about altering settings so that I can get the time I need onto one disc (110 minutes unfortunately!) What setting will offer me the best possible picture quality, regardless of encoding time, with compressor? Many, many thaks for any advice you regular user can offer!!
Happy Christmas in advance, Gareth

Gareth:
According what was posted in this thread:
http://discussions.apple.com/thread.jspa?threadID=760041&tstart=15
by Brian a lot of problems must be solved using the last 2.3 version.
Hope it helps !

Lots of problems with E6 - must be fixed soon (e.g...

I have used Nokia mobiles since 1999 and recently "upgraded" from an E71 to an E6. I have found far too many problems with the E6 and would like Nokia to explain what they are doing to fix these issues.
The E6 needs to have the @ symbol in the notifications area at the top of the screen when a new email arrives (like in the E71). It is really shocking that this feature is currently missing - especially as the E6 is supposed to be the upgrade route for E71 / E72 users.
The notification light in the 5-way button is currently useless because it is far too dim to see except in very dark conditions. The light must be turned up much brighter AND it needs to include the option of notifying when emails arrive.
Vibrate is too weak. This needs to be stronger (I believe a firmware update can fix this easily).
Lots of apps in OVI are not yet updated for the higher pixel density E6 screen compared to the E71, so lots of detail and buttons are far too small to use, especially in maps (where the text shrinks too small straight after enlarging a map).
Eg:
- Facebook app (based on the former Snaptu app), works fine but everything is tiny.
- Online maps in ViewRanger (the pre-downloaded OS sheets are fine as they can be enlarged without the text shrinking again).
- Most weather apps
Also, the browser shows web pages adjusted for mobile phones far too small. try looking at the Daily Telegraph webpage - it automatically goes into the mobile site and all text is so microscopically small that it is unreadable (the current solution is to use Opera Mini).
I want the widget that existed in the E71 for email notifications (it shows up a popup with the latest emails) back.
I want the function that tells you how long a call was (like E71) straight after the call.
I want the camera app to be available as a shortcut on the one-touch keys - as this would be the only way to have a physical key for firing up the app. Currently, one needs to find an on-screen icon, which can be a fiddle unless you have the icon on every homescreen.
A better choice of Themes needs to be pre-installed.
I almost feel like ditching my E6 and going back to my E71 because it actually did everything I needed.

I had E6, Im using past 1 years, now only its hanging,My warranty time also finished.

CopyRights problem with "expires at the fixed time" uat mode

Dear all
I found a problem with rights parameter
When I use rights parameter in uat mode or umt mode
it can't be work with this two modes($uat and $umt)
and I found a document in adobe jp
the document says "only uat mode works well with expire function"
so I change the rgihts to uat
but it still has problem and does not work
this is part of my ASP VBS code
startTime=DateDiff ("s","1-Jan-1970",Date())
endTime=DateDiff ("s","1-Jan-1970",DateAdd("n" , 1 , Now()))
strQueryParams = oGBLink.AppendToQuery("bookid", pSku, strQueryParams)
strQueryParams = oGBLink.AppendToQuery("rights", "$uat#"&endTime&"#"&startTime&"$", strQueryParams)
strQueryParams = oGBLink.AppendToQuery("price", CStr(pPrice), strQueryParams)
....and more
is there any problem with my code??

I don't see a problem with your code. You might put in a print statement and make sure that strQueryParams contains what you're expecting.
When you're testing, are you using the same book more than once? If so, ACS can get confused about which voucher to use and use an old one.
- either use a different book each time
- or after each test, reset Acrobat or Reader on your test download machine. Adobe has a KB article:

Many Trash problems with leopard and no fix

Hi
I posted that my trash is not emptying under any circumstances no one seemed to know how to solve this. i noticed that there are several people with trash issues (some not emptying until restart, others cant see the trash) i just hope that apple fix this with an update or something. meanwhile i am using a program called onyx to empty my trash and it works fine.

I am not an expert on this but i had a problem similar to what you experienced. I deleted tens of thousands of stuff at one go and it got stuck at one point. But the difference between your experience and mine is that it gave a dialog saying it cant find the file xxx to delete and also that i should click continue to proceed further. needless to say, i had to do that twenty to thirty times with each tiem a dialog popping up with same message but different file. when done, it seems to have deleted all other files except the ones it showed in dialog box. So i opened trash again and option clicked it and everything went away without any dialogs. hope that helps.
I dont know if that applies to secure emptying the trash.

Problem with RSCRM_BAPI (extraction to Fixed Lenght txt file)

Hi Experts,
I have a question about a RSCRM_BAPI limitation:
I want to extract a Query, using this transaction, to a fixed lenght .txt file. The query has a tabular structure like this:
CHARACT1 | CHARACT2 | CHARACT3 | CHARACT4 | KEYFIG_MONTH1 | KEYFIG_MONTH2 | .... | KEYFIG_MONTH12.
so i have a tabular structure with some CH and a KF repeated for the 12 month of the year.
The problem is that the fixed lenght .txt file extracted with RSCRM_BAPI stops to the month 11, month 12 is discarded. If i try to extract a .csv file with the same query all the 12 month are included in the file.
Question: Is it possible that RSCRM_BAPI has a row lenght limitation considering the fixed lenght .txt file?
Many thanks in advance.
Fabio

How did you sechudle the Query/Report Using BAPI, i'm having similar Problem. Please Can you help me out.
My problem is , i have a query which is schedule for every month 2 wed and a bapi is associated to The query.
for some reason's the query is not working properly .
Can you please help.

Event problem with JComboBox

Hi, javamen.
I ve gotten a little problem when working with Itemlistener interface. My combo has 4 options, in which the first one always appears when the applet starts up. Whenever the user DOESNT change it and submit the applet form, throught a button click, the applet gets a NullPointerException. But, if the user changes the option, i always get it, throught my interface' methods(ItemStateChanged). Of course, i know its because there was no combobox event, just a button event (click). So, how can i deal with this situation, since i need to get the combobox option content.
Regards, Euclides.

But, this is the question! I dont know how to initialize the combobox' first option. Help me, please! I am using the addItem method as follow:
MakeJCombo ( JComboBox ComboObj) {
ComboObj.addItem ("option1");
ComboObj.addItem ("option2");
ComboObj.addItem ("option3");
then:
public void itemStateChange(ItemEvent ie) ...
Object origem = ie.getSource()...
if (origem == ComboObj) ...

Problems with Mass Changes of fixed assets (Transaction AR31)

Hello all,
I have the next problem: I am trying to make a massive update of fixed assets , by means of the transaction ar31, but the system goes directly to the transaction so01 .
That I must do for being able to execute the transaction of normal way?
Thanks.

I think the same, but I don't understand :
<i>for a simple change better use BDC to tcode AS02.
-> you can use transaction-recorder SHDB</i>
I was investigating and I managed to deactivate wf, now I can execute the transaction, but not successful. The system show the next message " They do not exist responsible for task " and when checking the customizing the fixed assets (OAWF) the task have a responsible.
So I do not know that to do.
I hope you can help me
