JComboBox Locked after filling with Objects

I used Netbeans to create a vehicle management system. I have added a JComboBox from the Netbeans IDE to an JInternalFrame. When I call the following cord to populate the JComboBox, when run, the first item remains as the selection. I can get the other items in the drop down, but can not select any of them except for the first one. That means the JComboBox is locked. As the complete source code is big, I can not attach it here. I will email it if you need.
public static void fillList(ArrayList objects, JComboBox combo) {
combo.removeAllItems();
for (Object object : objects) {
combo.addItem(object);
Thanks in advance,
[email protected]

As the complete source code is big, I can not attach it here.We are not interested in the complete source.
I suggest you use the DefaultComboBoxModel and remove/add items directly to the model and not the combo box.
For more help create a [url http://sscce.org]SSCCE, that demonstrates the incorrect behaviour.

Text filled with objects

Illustrator
can anybody help me in this?
let say we need some text like " CIRCLE" and it should be filled with small circles (Like below) but not clipping mask mean the object should not flash cut on the edge of characters.
is there any effect, or we need to do it manually?

Sajid,
Here is a(nother) way to get a nice and orderly distribution of dots (that do not touch one another). It may be further optimized, beyond what is shown.
You may (specifics applying to an S):
1) Create the lettershape or Type>Create Outlines from an existing live Type letter;
2) If needed (starting with live Type), change from Fill to Stroke and delete the end segments;
3) If needed (starting with live Type), Ungroup and Object>Compound Path Release and possibly reverse either path so both have the same direction, see below;
With only the outer paths (which should have matching Anchor Points),
4) Object>Blend>Options, with Specified Steps set to the number of inner paths (2 in the case shown), and Orientation>Align to path;
5) Object>Blend>Make
6) In the Stroke palette, set the Stroke Weight to the desired dot thickness, set Cap>Round Cap, and tick Dashed Line with Dash = 0 and Gap = Stroke Weight+desired gap between dots, corresponding to the gap between the rows of dots;
7) If needed, adjust the Dashes to fit, inbuilt (in the options) in the newest version, in older versions, you may use the free Adjust Dashes script avaialble here:
http://park12.wakwak.com/~shp/lc/et/en_aics_script.html
Below is shown an S in Helvetica Bold at 144pt, with Stroke Weight = 12pt and Gap = 15pt (before adjustment). It may be further optimized.
To reverse the direction of a path, you may select the path and:
A) Object>Compound Path>Make;
B) In the Attributes palette tick Reverse Path Direction On;
C) Object>Compound Path>Release.
You can see whether it is needed when you make the blend; if it is messy, reverse either path.
You can also see the path directions by Effect>Stylize>Add Arrowheads; they should be at the same end.

Has anyone experienced Labview 8.2 crashing when attempting wire a cluster filled with object and task references?

I am getting a complete shutdown (crash) of Labview 8.2 when placing the wiring tool over a cluster that is filled with task and object references. The crash occurs on all computers I have attempted it on and happens throughout all VIs in all classes that distribute multiple references throughout the VI using a cluster. The entire project I am developing is programmed in GOOP. Has anyone experienced anything like this? I have provided a screen shot of the place where the crash is generated. Let me know if anyone has any insights.

There are several known crashes with LVClasses. One of the easiest
fixes is to load your application into memory and then hit
ctrl+shift+click on the Run arrow of your top-level VI. Then do
File>>Save All. You might also try selecting that wire (with the
selection tool -- use the Tools Palette to explicitly select a tool
other than wiring) and deleting it and then rewiring those terminals.

Zen 32 GB locks after sync with AudibleManager or WMP 11

Have a new Zen 32 GB and after syncing Audible content using either Audbile Manager or WMP , the player locks - screen goes dark, blue light on side stays on. This is repeatable! If I hit the reset button with the paper clip, the blue light turns off, then it can be turned on again but it rebuilds the library, every time. This is very irritating - any suggestions? My computer has WinXP SP3, latest Zen firmware (.2.03)

Thanks for the suggestion but I had already tried that. Still keeps happening whenever I add or delete Audible content.
Maybe someone else that uses Audible will chime in. I have not used that format or software. Sorry I'm not more help

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

Can't figure out why colors don't totally change when you select type with curser? It looks like it has by looking at it, but when you highlight the area after the old color is still there. It happens with objects to. Driving me NUTZ. Help!

Select the text, and open the Appearance palette (Come on guys, text highlight is irrelevant, it happens to objects too says the OP), and see what's listed there. For a simple text object, there should only be a line item "Type", followed by "Characters", and when double-clicked the Characters line item expands to tell you the stroke and fill color. For a basic object, there should be a fill and/or stroke.
What happens sometimes, is that you end up adding extra strokes/fills to objects or text, and the appearance palette is where that will be noted. Especially when you are dealing with groups, and/or picking up a color with the eyedropper, you may inadvertently be adding a fill or stroke on top of something. You can drag those unwanted thingies from the Appearance palette into its own little trash can.

Objects in transports are not locked after DB migration

Hi all,
we had an OS\DB migration to Linux\Oracle.
The transports were Not released prior to the migration.
after migration, when changing an Object the system asks for a new transport allthough there a transport allready exists with the locked object.
this way , we have the same object in 2 different transports - and the system displays the object is locked in both.
please advise.
many thanks.

How to fill an object made with line segment?

I made some objects with the line segment tool, but i cant seem to fill them. Not even when i group the lines and try to fill after.
Anybody an idea? thanks

Live paint will do the trick you select the lines and click on the live paint bucket tool which will make the lines a part of live paint group, there are options for controlling the gap distance.
Then select a color and click the live paint tool somewhere in the area that the lines are used to define. it will fill with that color.n CS 2 and 3 I think well CS3 for sure.

How can I allow the application to line through a field that has been locked after being digitally signed? We have multiple sections on a form with some fields being proposed information and other in another section having the approved information. once

How can I allow the application to line through a field that has been locked after being digitally signed?
We have multiple sections on a form with some fields being proposed information and other in another section having the approved information. once the approved information is entered we line through the proposed field so the data entry clerk won't pick up the wrong information. However we are receiving an error when attempting to enter data in the field which we have this edit. Error property: line through cannot be set because doing so would violate the document permission setting. any idea how we can get around this issue?

You can control which fields are locked down after signing by setting up a collection. Then those that are not locked can be changed after signing. If this is not possible, then the line outs must occur prior to signing.

Gnome 3.2 suspend with status menu: screen is not locked after wakeup

Locking the screen with gnome-screensaver-command --lock or with the lock screen option from the status menu works fine.
However, when the suspend from the status menu is used, although it does seem to go into lock mode before it suspends (the screen goes black and there is a little lock icon in to top corner), it never asks for a password after it wakes up. This happens on both my laptops with gnome3 by the way.
The wiki article https://wiki.archlinux.org/index.php/Gn … ter_resume tells me to use
# gsettings set org.gnome.power-manager lock-use-screensaver 'false'
But that key doesn't exist in gnome 3.2.
Any ideas ?

In the meantime I found the following:
- When I suspend with the power button, the screen is locked, but not when I use the status menu option
- This seems to be related to the screen setting 'Lock screen after'. I had it set to 1 minutes. When I change it to 'after the screen goes blank' the
problem doesn't seem to occur.
So, the way it looks now, it uses the same settings for delaying the locking the screen after the screensaver kicks in when locking the screen before suspend.
Which doesn't make much sense. And then the behaviour is still inconsistent with the power button suspend.

Problems with the table of lock is fills

Hello all
In my system in occasions repeated, the table of lock it is fills
Per this problem, I did open the message with SAP and in this message the sap support, I replied that increase the parameter value "enque/table_size" at 200 MB, this is the value for 200 MB (202752)
With the parameters implemented in my system, the table of lock to a is fills, this is not resolved my problem and continuos.
Other comment is that the value maximun is 200 MB for this lock table.
I think the problem is in the programs that executed this lock, when is executed some programs that sent the information at my stores, is when the lock table fills.

Thaks for you answer

Filling Worflow container with objects (OOAD)

Hi Gurus,
I have created a workflow,which has abap objects as container element. Can anyone let me know how can I fill the container element with object..I have tried with marcos as mentioned in the library..but not container is not filled ..plz advice....
Create a variable for the object reference. Use the following command to do this:
DATA <Object> TYPE SWC_OBJECT.
Create the object reference. Use the following command to do this:
SWC_CREATE_OBJECT <Object> <ObjectType> <ObjectKey>.
Write the object reference into the container using the following macro instruction:
SWC_SET_ELEMENT <Container> <ContainerElement> <Object>.
Thank you

BalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.
SomeObject someObject = null; // The someObject reference is null.
someObject.doSomething(); // Invoking a reference which is null would throw NPE.

Filling an object with a pattern without distortion?

I have this camo pattern:
wich already tiles seemlessy but when i turn it into a swatch it won't tile. it distorts the pattern and blows it up instead of using it as is and tiling:
what is the problem here? can i scale it in some option menu? can i control the orientation? im creating a vector based logo, is this the right way to go about filling the object with this pattern?
i want it to be scaled and tiled. what is the best way to go about it? what would u do? thanks in advance

yup i thought so. it HAS to be vector based.
it does not have to be vector, it can be jpeg or gif, but it has to be embedded...as for not using it in a logo, Scott can explain that.
255x247 px
the object is any size as its a vector. How are u filling yours? photoshop then a clipping mask?
I meant the size of the camo image in relation to your vector object, not the actual size in pixels.
in this sample I grabbed a GIF, embedded it, dragged it to the swatches palette, sent the image to back, then filled both the small object and the big object with the gif-embedded swatch, just to illustrate what happens with the size position.

You have to restore the iPad by syncing to the original computer that you synced to.
