Hello All, Greetings..!!

I am new to blackberry app development. I am trying to make an app where in i have a picture scroller , the functionality i want to add is that when we click on a picture scroller image, the image should appear highlighted or little raised from rest of the images, but i am not able to do it.

In picture scroller, by default center image appears highlighted. If i overlap picture scroller with another image that remains fixed in such a way that as and when images from scroller crosses that fixed image it appears raised.

Could you please help how do i give this functionality, i am not able to implement it.

Thanks & Regards

Hi Henna

Try this solution

Add listner to picture scroll field

_pictureScrollField.setChangeListener(this);

Implement navigation click method

----------------------------------------------------

protected boolean navigationClick(int status, int time)
{
if(_pictureScrollField.isFocus())
{
_pictureScrollField.setHighlightStyle(HighlightStyle.SQUARE_BORDER);

return true;
}

return super.navigationClick(status, time);
}

implement FieldChanged method

----------------------------------------------------

if(field instanceof PictureScrollField){

 _pictureScrollField.setHighlightStyle(HighlightStyle.NO_HIGHLIGHT);

}

Hope this helps....

Sorry I do not actually understand what you are asking for.  Can you give us a screen shot showing something similar.

Hi Heena,

As per my solution is concerned..this will put a red border around the selected image.

No idea as per now how to raise this.....

hi rabi,

could the fields be overlapped, i mean

1. i have this particular square image filled with white color, and i placed it in the center, keeping it fixed

2. i have this picture scroll a little below  that  fixed image such that it overlaps that fixed image, and when we scroll the images included in the scroll overlaps on it and it appears raised.

i hope u understood what am saying.

Thanks

Hi

Not sure if we can place a fixed image inside picture scrol.....

Have tried diffrent styles available in 

PictureScrollField.HighlightStyle

like ILLUMINATE_WITH_SQUARE_BORDER etc....

hey rabi,

i wont place a fixed image inside picture scroll,

but the picture scroll will overlap over the fixed image..

i hope you got it now.

i have tried applying diferent styles, it dint help.

Hi Heena

I dont think it is so simple to implement...i dont know how to fix one image and overlap another field onto it.

I think it is best to implement your own custom class and draw accordingly.

Thanks
