hi,

I am developing a  login password screen for my application.

 EditField user=new EditField("User ID:","",10,EditField.FIELD_HCENTER|EditField.FIELD_VCENTER);
 PasswordEditField password=new PasswordEditField("Password:","",10,PasswordEditField.FIELD_VCENTER);
 

Functionality wise its ok but i am just wondering how can i 

1. draw editfield into the centre of the screen

2. how can i change the background color of the fields.

Hi,

Plz. go thru the properties of these fields. There are properties like 

(1.) EditField.FIELD_HCENTER and EditField.FIELD_VCENTER,which are inherited from " class net.rim.device.api.ui.Field".

      Also you can use Mangers like HorozontalFieldManager and VerticalFieldManager to make it align as you wish..

(2.)You will have to override:    public void paint(Graphics g){ }

I have already tried these VCENTRE AND HCENTERE abut they don't work in my case.

I want to put these two fields in the centre of screen.

Any Suggestions!

how are you adding the field to your screen?

Make a custom Manager that will help you place the fields as u like... 

CustomManager cmanager = new CustomManager();

cmanager.add (user); 

cmanager.add(password);

add(cmanager); 

The customManager class would extend manager... and it overrides the sublayout method that positions the children of manager.. 

something of this sort... 

private class CustomManager extends Manager {
     
        protected CustomManager() {
            super(NO_VERTICAL_SCROLL);
        }
      
        protected void sublayout(int width, int height) {
           if (getFieldCount() > 0) {
                layoutChild(user, width, height);
                layoutChild(password, width, height);
                int y = 10; //this is assumption
                setPositionChild(user, (Display.getWidth()- user.getContentWidth())/2, y);
                y += user.getContentHeight();
                setPositionChild(password, (Display.getWidth() - password.getContentWidth())/2, y);
               
                setExtent(width, Display.getHeight());
            }
        }
 }

To change background colour.. override the paint method...
