Removing GUI-element from JFileChooser

Hello,
I'm using JFileChooser to select a directory. Superfluously the JComboBox
for the filetypes keeps being displayed. Can this be supressed?
Greetings
Joerg

I don't think there is anyway to do this with the standard calls. You should be able to use getComponents() (probably recursively) to find the combobox and make it invisible.

Kill a thread and remove the element from the vector

Hi All
I have attached each Vector element to a thread which I later want to kill and remove that element from the Vector.
Thread.join(milliseconds) allows this functionality to let the thread die after n milliseconds.
However, I want to delete this element from the Vector now.
Can someone please throw some light on this?
Here the code I have written for this:
try
     System.out.println(counter);
     int xCoord = generator.irand(25,200);     // X-coord of AP
     int yCoord = generator.irand(25,200);     // Y coord of AP
     listMN.addElement(new MobileNode((int)mnId,new Point2D.Double(xCoord,yCoord)));
     listMNcoords.addElement(new Point2D.Double(xCoord,yCoord));
     for(int i=0;i<vnuBS.returnBSList().size();i++)
          if(vnuBS.returnBSListCoords().get(i).contains(xCoord,yCoord)&&(vnuBS.returnBSList().get(i).getChannelCounter()<=3)&&(vnuBS.returnBSList().get(i).getChannelCounter()>0))
               double c = exponential() * 10000;
               long timeToService = (long)c;
               System.out.println("BS "+vnuBS.returnBSList().get(i).id+" is connected to MN ");
               vnuBS.returnBSList().get(i).reduceChannelCounter();
               System.out.println("Channel Counter Value Now: "+vnuBS.returnBSList().get(i).getChannelCounter());
               mobileNodesThread.addElement(new Thread(listMN.elementAt(mobileNodeCounter)));
               mobileNodesThread.elementAt(mobileNodeCounter).setName(mobileNodeCounter+"");
               mobileNodesThread.elementAt(mobileNodeCounter).start();
               mobileNodesThread.elementAt(mobileNodeCounter).join(100);
//                              System.out.println("Died");// thread dies after join(t) milliseconds.
               System.out.println("ListMN getting generated : " + mobileNodesThread.get(mobileNodeCounter));
          else if(vnuBS.returnBSListCoords().get(i).contains(xCoord,yCoord)&&(vnuBS.returnBSList().get(i).getChannelCounter()<=0))
               listMN.remove(this.listMN.lastElement());                         //dropcall
               System.out.println("Removed "+mnId);
               removeCounter++;
               mnId = mnId--;
               mobileNodeCounter--;
          mnId = mnId+1;
     Thanks a lot.

I'm not sure if what you are trying to accomplish is correctly implemented.
The method join does not kill the thread. It will wait for the specified time for the thread to exit. If you want the thread to run for a specified ammount of time, develop the run method of that thread with that in mind. Do not try to kill it from the outside, but let it terminate itself (gracefull termination).
Now for your question regarding the vector (you should probably be using ArrayList nowadays): I would implement the observer pattern for this job. Make the threads post an event on the interface when they are done, let the main thread register itself with the threads and synchronize the method that handles the events. In that method you can remove the object from your list.
I'm not sure if you want to use thread anyhow, could you tell us what it is that you are trying to accomplish?

Hi Folks
In a webdynpro application,
I created a table and witten the below code to populate the table

     First_Table_Element.setF_Value("One");
     wdContext.nodeFirst_Table().addElement(First_Table_Element);
     First_Table_Element = wdContext.nodeFirst_Table().createFirst_TableElement();
     First_Table_Element.setF_Value("2");
     wdContext.nodeFirst_Table().addElement(First_Table_Element);
As per the code, i got 2 row in the table.
But , i have one Empty row on top of the table , how to get ride of this.
i find the same problem happening with dropdown too, where i used DDBI, i populated a the content as mention, but i initial 2 row as blank and then i have my own elements ,as per my code.

Removing specific element from a list

Hello, I'm very new to java, and to programming in general.
I'm trying to write a secret santa app for my family for christmas. Essentially the idea is that 7 names are put into a list, and each time a name is "pulled" (i.e. randomly assigned to a name /= itself) it will be removed from the list of available names to assign.
String[] nList = { name2, name3, name4, name5, name6, name7 }; // store names for random use
Random r = new Random();
name1assign = nList[r.nextInt(nList.length)];
String[] nList2 = { name1, name3, name4, name5, name6, name7 };
name2assign = nList2[r.nextInt(nList2.length)];
My goal for this is to take the string that is equal to name1assign, and remove an element with that string from nList2.
Can anyone give me some advice in this matter?
Thanks.

Sometimes a null value is used to indicate an 'empty' array element, but it would be better to try collections instead.
You could use an ArrayList instead of an array. This has methods to remove items by index or value.
An ArrayList also works with Collections.shuffle, which allows you to simply iterate over the list and not deal with random or removing elements at all.

I can't remove Yandex Elements from the Open menu list with right mouse button and Tools menu although I removed Yandex. I think it slows down Firefox.

I downloaded Freeyoutube downloader from internet and somehow got yandex installed in my computer with toolbars on firefox.Despite I removed Yandex from my computer Yandex elements still stays in open menu when right mouse button clicked and in the Tools menu. I tried to uninstall Firefox, remove yandex registry from windows registry and restart computer, and then reinstall firefox, Yandex elements still hangs there. Firefox is now running very slow compared to the running before Yandex.

hello, please try all these steps:
# [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords)
# afterwards go to the firefox menu [[Image:New Fx Menu]] > addons > extensions and in case there are still extensions listed there, disable them.
# finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.

Remove an element from XML present in CLOB column

Hi,
I need to remove element TEST2 and TEST3 from the below XML which is present in the CLOB column of a table. I need to do this using DBMS_XMLDOM package of Oracle as my existing code is using the same -
<ROOT>
<LEAF1>
<TEST1>TEXT1</TEST1>
<TEST2>TEXT2</TEST2>
<TEST3>TEXT3</TEST3>
</LEAF1>
</ROOT>
Hence the final o/p should be like
<ROOT>
<LEAF1>
<TEST1>TEXT1</TEST1>
</LEAF1>
</ROOT>
Please suggest how to achieve this.

Something like this?

Remove an Element from the Element level...?

i have appliction and a component. i put the component to stage using the addElement(new myComponent());
i use vertical layout so you can add the component over and over by clicking the button at the application level.
I just want to be able to delete the components that i choose after adding it so removeElement... tried the this. route not working
any help is appreciated
Here is the application code:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" xmlns:comp="comp.*">
    <fx:Declarations>
        <comp:PhotoButton />
    </fx:Declarations>
   <s:SkinnableContainer x="14" y="108" width="180" height="325" backgroundColor="#CCD9DE">
        <s:Group id="layerGroup" width="180" y="33" >
            <s:layout>
                <s:VerticalLayout gap="0" />
            </s:layout>
        </s:Group>
    </s:SkinnableContainer>
   <s:Button x="10" y="63" label="Button"
        click="{layerGroup.addElement(new PhotoButton());}"/>
</s:Application>
and my component:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"

    <s:layout>
        <s:HorizontalLayout />
    </s:layout>
    <s:SkinnableContainer backgroundColor="#ffffff">
        <s:Button id="removeBtn" label="X" width="29" x="0" y="0"/>
        <s:Button x="25" y="0" label="layer"/>
    </s:SkinnableContainer>
</s:Group>

I figured it out .... so in the component I wrote a function that did
this:
private function sendClick(event:Event):void{
                parentApplication.layerGroup.removeElement(this);
thanks for looking at it!

Remove element from GUI

Hi guys,
I am adding elements to the gui like this:
var myText = win.add("edittext", undefined, "whatever");
Later in my code I need to remove this element from UI. Is it possible?

Use the remove() method: win.remove(myText);
In general: container.remove(child);
You can add it later later but then, if you use the autolayout, you'll need to relayout: win.layout.layout(true) otherwise it won't show up

Removing element from vector

I am trying to remove an element from a Vector and using the ff code:
Vector abc = getVector();
int index = 0;
abc.removeElementAt(index);
The element is not being removed, when i go back to check the number
of elements in the vector, it is still the same.
Please give me any ideas to make this work.

Try this,
Vector abc = getVector();
int index = 0;
System.out.println("Size before : "+abc.size());
abc.remove(index);
System.out.println("Size after : "+abc.size());
What is the o/p?

Remove element from multi-surface

Hi there,
I am trying to fix some invalid multi-surface geometries that are derived from a 3D source, many of which have ORA-54514: overlapping areas in multipolygon. I can find out which subset geometry (aka the element in this context) is causing the problem with the VALIDATE_GEOMETRY_WITH_CONTEXT function, and even extract just that element (SDO_UTIL.EXTRACT3D), but how do I remove that element from the geometry (and hopefully fix the problem)? Is there any way to view the position of the element within the geometry in the same manner that the Extract3D function requires (i.e. 0,0,1,1,0,0,7), I can return this for the problem element but not for any of the other subset geometries. Unfortunately I'm using FME to load the geometries and the topology validation here is not as robust as Oracle, which means I need to fix the geometries once they are loaded, but there doesn't seem to be any tools to do this?
Regards
Dan

Hi Dan,
instead of removing the offending element, how about extracting all the correct ones? Should give the same net effect, I think.
Re FME: I find I can usually validate geometry enough that it will at least pass Oracle's Validate, but that's usually only 2D or 2D with a Z-ordinate (2.5D, as some folks call it).
Regards,
Stefan

Remove element from arraylist, jstl

HI there,
i use bean for an array list
<jsp:useBean id="list" scope="page" class="java.util.ArrayList"/>
then i add element in the list
later i need set up a loop does the following:
remove one element from the list and process it
until the list is empty
is this (romoving elment from a list) possible to be done using only jstl
thanks

No, it is not possible.
JSTL is for use on JSP pages.
JSP pages are meant for "display"
You sound like you are doing processing - this sort of stuff more properly belongs in a java class.
