`data_table.getTableHeader().setReorderingAllowed(false);` should do the job, unless you mean that the user can resize column headers.

To anyone having this problem using **Netbeans** IDE you can disable the user from dragging columns in the JTable by doing the following steps.

  [![Customizer Dialog][1]][1]

 - Right click the table   
 - Select Table contents   
 - Click the columns tab    
 - Uncheck the Allow to reorder columns by drag and drop

I am creating a mobile simulator that mocks the appearance and functionality of an iPhone (and other devices later) in a web browser, using 100% javascript, HTML5, and CSS, with the simulator fully functional with only client side code.

While trying to accomplish this task with as little modification as necessary to the original app projects themselves to be hosted in the simulator, I am injecting the `&lt;script&gt;` and `&lt;link&gt;` tags into the head of the page, then loading the html into a `&lt;div&gt;` screen.

The problem is that when I load in a new css file, it (obviously) overrides the one I&#39;m using to style the page, and therefor some elements are affected (ex the background changes color).

My question is: Is there any way to limit the &quot;scope&quot; of an external `.css` file to apply only to objects within the `&lt;div&gt;` screen? Would it make any difference if instead of me injecting it into the `&lt;head&gt;` of the page, I inject it into a `&lt;style&gt;` element in the `&lt;div&gt;` screen?

Limit scope of external css to only a specific element?

I am passing `date` value to my custom filter this way:

    angular.module(&#39;myapp&#39;).
      filter(&#39;filterReceiptsForDate&#39;, function () {
        return function (input, date) {
          var out = _.filter(input, function (item) {
            return moment(item.value.created).format(&#39;YYYY-MM-DD&#39;) == date;
          });
          return out;
        }
      });

I would like to inject a couple of scope variables there too, like what I can do in directives. Is that possible to do this without having to passing these vars explicitly as function arguments?

I have declared my `JTable` as:

    data_table = new JTable(info, header) {
        @Override
        public boolean isCellEditable(int row, int column) {
            return false;
        }
    };

But I&#39;ve seen that at runtime it&#39;s possible to **drag the columns** with mouse.
How can I disable that?

I created a CircularImageView with this question: [Create circular image view in android][1]

Download project on [**GitHub**][2]

1) This is the CircularImageView class :

    public class CircularImageView extends ImageView {
        public CircularImageView(Context context) {
            super(context);
        }

        public CircularImageView(Context context, AttributeSet attrs) {
            super(context, attrs);
        }

        public CircularImageView(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
        }

        @Override
        protected void onDraw(Canvas canvas) {
            Drawable drawable = getDrawable();
            if (drawable == null) {
                return;
            }

            if (getWidth() == 0 || getHeight() == 0) {
                return; 
            }
            Bitmap b =  ((BitmapDrawable)drawable).getBitmap() ;
            Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);		

            Bitmap roundBitmap =  getCroppedBitmap(bitmap, getWidth());
            canvas.drawBitmap(roundBitmap, 0, 0, null);
        }
	
        public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
            Bitmap sbmp;
            if(bmp.getWidth() != radius || bmp.getHeight() != radius)
                sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
            else
                sbmp = bmp;
		
            Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(), Bitmap.Config.ARGB_8888);
            final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());

            Paint paint = new Paint();
            paint.setAntiAlias(true);
            paint.setFilterBitmap(true);
            paint.setDither(true);      
            paint.setColor(Color.parseColor(&quot;#BAB399&quot;));

            Canvas c = new Canvas(output);        
            c.drawARGB(0, 0, 0, 0);
            c.drawCircle(sbmp.getWidth() / 2+0.7f, sbmp.getHeight() / 2+0.7f, sbmp.getWidth() / 2+0.1f, paint);
            paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
            c.drawBitmap(sbmp, rect, rect, paint);

            return output;
        }
    }

2) I use in my layout like this :

    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;

        android:gravity=&quot;center&quot;
        android:orientation=&quot;vertical&quot;
        android:padding=&quot;10dp&quot; &gt;

        &lt;com.mikhaellopez.circularimageview.CircularImageView

            android:layout_width=&quot;@dimen/image_view_size&quot;

            android:layout_gravity=&quot;center&quot;
            android:background=&quot;@drawable/border&quot;

What exactly is the difference between **core pool size** and **maximum pool size** when we talk in terms of `ThreadPoolExecutor`?  
Can it be explained with the help of an example? 

Core pool size vs maximum pool size in ThreadPoolExecutor

I have `@Autowired` service which has to be used from within a static method. I know this is wrong but I cannot change the current design as it would require a lot of work, so I need some simple hack for that. I can&#39;t change `randomMethod()` to be non-static and I need to use this autowired bean. Any clues how to do that?

    @Service
    public class Foo {
        public int doStuff() {
            return 1;
        }
    }

    public class Boo {
        @Autowired
        Foo foo;
        
        public static void randomMethod() {
             foo.doStuff();
        }
    }



@Autowired and static method

Source:

    public class TestVarArgs {
      public void varArgsMethod(Object ... arr) {
         System.out.println(arr.getClass().getName());
         for(Object o : arr) {
           System.out.println(o);
         }
      }

      public static void main(String[] args) {
        TestVarArgs tva = new TestVarArgs();
        tva.varArgsMethod(args);    
      }
    }


Compile:

    javac TestVarArgs.java 


Error:

    TestVarArgs.java:15: warning: non-varargs call of varargs method with inexact argument type for last parameter;
    cast to java.lang.Object for a varargs call
    cast to java.lang.Object[] for a non-varargs call and to suppress this warning    
    tva.varArgsMethod(args);     
    ^

    1 warning


I am using `javac 1.6.0_20` and the code o/p indicates that a non var arg call was made anyways.


Why do I get a compilation warning here (var args method call in Java)

Providing white space in a Swing GUI

I have installed IntelliJ IDEA (13.1.1 #IC-135.480) and JDK 1.8.0 (x64) and I generated some GUI with the GUI Form designer. 

Then I ran the code and realized that something is not alright. 

Here is a Screenshot of my GUI:
![Buggy Rendering JDK 1.8.0][1]

The rendering of the Font seems to be not OK. Additionally the Button looses its Text, when I move my mouse over it.

So I installed JDK 1.7.0_40 (x64), recompiled the Project and ran it again.

The following Form appears, when i use JDK 1.7:
![Rendering OK JDB 1.7.0_40][2]

The Rendering seems to be OK and the Button is also OK.

So I installed the newest Graphics and Chipset drivers and much more, but the problem still exists.
Have you ever had such problems with Java Swing UIs? Could you help me to fix my problems? 
Any help would be greatly appreciated.


----------

UPDATE:
-------

 

I created a small Project with only 1 JTextArea and 1 JButton and i have the same rendering problems.

According to Andrew Thompson i changed the setSize() and I start from EDT. The Example below:

    package at.maeh.java.client.simpleTextClient;
    
    import javax.swing.*;
    import java.awt.*;
    
    public class SimpleClient extends JFrame {
        private JPanel panel1;
        private JTextArea textArea1 = new JTextArea();
        private JButton button1 = new JButton();
    
        public SimpleClient() {
            super(&quot;SimpleClient&quot;);
    
            // Panel
            panel1 = new JPanel();
            panel1.setLayout(new FlowLayout());
    
            // BUtton
            button1.setText(&quot;TestButton&quot;);
    
            // TextArea
            textArea1.setColumns(40);
            textArea1.setRows(15);
    
            // Add Components
            panel1.add(textArea1);
            panel1.add(button1);
    
            // Add to Frame
            this.getContentPane().add(panel1);
    
            // pack and set Visible
            pack();
            setVisible(true);
    
            System.out.println(&quot;Constructor EDT: &quot; + SwingUtilities.isEventDispatchThread());
        }
    
        public static void main(String[] args) {
            SwingUtilities.invokeLater(SimpleClient::new);
    
            System.out.println(&quot;Main EDT: &quot; + SwingUtilities.isEventDispatchThread());
        }
    }
       
The result is a simple JFrame with the Components in it.

![SimpleClient -&gt; Screenshot immediately after Start][3]

When I write some Text, or moove my mousePointer over the Button the components get rendered like this (Text: testsentence.123; Button-Label: TestButton)

![after writing - or mouse over][4]
