hi,

           LabelField  tabHome = new LabelField("HOME",Field.FOCUSABLE)
                                {
                                    protected boolean navigationClick(int status,int time)
                                    {
                                        // write your code on click
                                        return true;
                                    }
                           
                                };

I tried this an it worked on a single field. However, I tried to extend it by doing it on more than one field

eg

        _authorTab = new LabelField("Author", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT )
        {
            protected boolean navigationClick(int status,int time)
            {
                displayauthorTab();
                return true;
            }
            
        };
        
        _fileManagementTab = new LabelField("File Management", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT)
        {
            protected boolean navigationClick(int status,int time)
            {
                displayFilemanagementTab();
                return true;
            }
        };

When I do this, the code does not do a new build (the same code is on teh simulator) - if I have more than one label field with the navigation click even if I comment out the calls.

        _authorTab = new LabelField("Author", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT )
        {/*
            protected boolean navigationClick(int status,int time)
            {
                displayauthorTab();
                return true;
            }
            */
        };
        
        _hTabManager .add(_authorTab);

        _fileManagementTab = new LabelField("File Management", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT)
        {/*
            protected boolean navigationClick(int status,int time)
            {
                displayFilemanagementTab();
                return true;
            }*/
        };

It still fails. I need to remove the brackets around all but one to make it build new code. eg

        _authorTab = new LabelField("Author", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT );

        _fileManagementTab = new LabelField("File Management", Field.FOCUSABLE | Field.HIGHLIGHT_SELECT)
        {
            protected boolean navigationClick(int status,int time)
            {
                displayFilemanagementTab();
                return true;
            }
        };


Is there a bug in the compiler or is what I am trying to do not supported?

Hi,

I suggest you create some custom label field and use this label for different purpose.

public class LabelFieldCustom extends LabelField {

 public LabelFieldCustom( String text, int color, long style)

{

} 

}

There in the class you can put the navigationClick( ) method. I hope it will work. Check it.

Hi, I tried small bit of code and its working fine.. Check this out..

class MyScreen extends MainScreen

{

   LabelField label=new LabelField("click",LabelField.FOCUSABLE);

Myscreen()

{

   add(label);

   label.setFocusListener(listen);

}

FocusChangeListener listen=new FocusChangeListener()

{

   public void focusChanged(Field field,int eventType)

   {

     if(field==label)

     {

       Dialog.alert("Label clicked");

     }

   }

};

Hope this code will help you...

I ended up using this solution.

The actual problem is defined at this link below. http://supportforums.blackberry.com/t5/Java-Development/Eclipse-wont-build/td-p/418217 It seems that by adding the navigationClick event or even just the braces added an extra class and made me jump above the 71 class bug (defined in the link above). I defined the JDK path in my system path variable and it now works.

Excellent.

Can you mark this as solved please?

[angelo_f]

I can't see where to mark it solved. I didn't create the thread - is that sopping me from having an option to mark it solved?

[peter_strange]

You are rifght, you can't.
