Hi,all

In my project, i encountered a problem：

i found that  between the images ,setMargin() do not work!

here's  my test codes.

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.component.BitmapField;
import net.rim.device.api.ui.component.SeparatorField;
import net.rim.device.api.ui.container.HorizontalFieldManager;
import net.rim.device.api.ui.container.MainScreen;

public class BB extends UiApplication {

	public static void main(String[] args) {
		BB app = new BB();
		app.enterEventDispatcher();
	}

	public BB() {
		pushScreen(new BBScreen());
	}

	class BBScreen extends MainScreen {

		BBScreen() {
			setTitle("TEST");
			HorizontalFieldManager hfm = new HorizontalFieldManager(
					USE_ALL_WIDTH);
			BitmapField bmf1;
			BitmapField bmf2;
			BitmapField bmf3;

			bmf1 = new BitmapField(Bitmap.getBitmapResource("loading.png"));
			bmf2 = new BitmapField(Bitmap.getBitmapResource("loading.png"));
			bmf3 = new BitmapField(Bitmap.getBitmapResource("loading.png"));

			bmf1.setMargin(50, 20, 50, 20);
			bmf2.setMargin(50, 20, 50, 20);
			bmf3.setMargin(50, 20, 50, 20);

			hfm.add(bmf1);
			hfm.add(bmf2);
			hfm.add(bmf3);

			add(hfm);
			add(new SeparatorField());
		}
	}
}

 and the results is

i searched in the past posts,but nothing found.

because when i  focus to the image ,there's a border,so i can't use setPadding().

very strange problem,can anyone help me?

The distance between images should be 40 ,but  it  is  20.

That is working as designed, but it caught me out too initially. The Managers maintain the margin between Fields as a single value equal to the greater of the 2 margins set for adjacent fields, in your case 20. NOT as the sum of the 2 margins between 2 adjacent fields.

That is correct. If only I could find the resource. There should be some article in the KB that shows how a field is arranged. It shows Content, Padding, Border, and Margin.

They have something like this when you look at the HorizontalFieldManager documentation for API 6.0 (scroll down if you don't see it).

It has finally been documented in the 6.0 API documentation. Check the entries for HorizontalFieldManager or VerticalFieldManager, for example.

hi, rcmaniac25, Thanks for API 6.0 Docs!

This figure shows all.

THX all!

I should seriously look at API 6.0.
