Hello,

I have a screen with several fields in a VerticalFieldManager.

I would like a focused field to be as much near the top of the screen as possible when I call setFocus on it.

Right now, the focused field is on the bottom of the screen (as if I scrolled down until I reached it).

I want it to be on the top of the screen.

How can I do that?

thanks

call the setFocus() method on the field that you want to have the focus.

that's what I do but it doesn't put the focused field on the top of the screen, its at the bottom

Sorry, you've lost me.

If you want the last field at the bottom of the screen to be at the top of the screen, then you need to put it there.

Not sure you got what I meant.

I have a vertical field manager too big for the screen. I have a button at the top of the VFM.

When I press the button I want to "search" for a field. At the moment I use setfocus on my field, but when I do that the field is a the bottom of the screen, like this:

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

blabla1

blabla2

blabla3

blabla4

FOCUSEDFIELD

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

I want it to be like that:

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

FOCUSEDFIELD

blabla5

blabla6

blabla7

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

How I can put it up more?

Look at Manager.moveFocus()

I tried it but thats not what I need since I don't know how many field there is going to be below.

I really just want to dynamically select a field and "put" it at the top of the screen.

Solved it:

((TitleField)mgr.getField(0)).setFocus(); // scroll it to the bottom of the screen
getScreen().scroll(Screen.DOWNWARD); // make it go up but focuses the bottom most element
((TitleField)mgr.getField(0)).setFocus(); // reset the focus to the field, now at the top
