How to focus on a specified item?

[baihaoping]

I want to focus on a TextField every time I show a Form.Did anyone know how?

[Jason Glass]

should be able to use form.setselected(item) or is it item.setSelected, note, this is only MIDP 2.0

It seems it's not possible to set focus, right?

[Jason Glass]

we were using setselected, which from a MS standpoint, is similar to setfocus

but had to remove it, or put in preprocessor statements, for doing MIDP 1.0 builds as it was not supported.

I think it works?

[baihaoping]

Sorry,I don't find a any method similar to setSelected.

[Jason Glass]

you, and juarez are so correct, i am sorry, it is only for a list, i.e. lcdui.list

there is getselectedindex and setselectedindex methods

I was going through all this code, and I just kept seeing it 20 plus times, and though it was inherited from lcdui.item

I apologize

Anyone know how to implement something similar?

This is exactly what I wanted to do in a game I'm developing. The user needed to input text into a textfield, so I wanted that field focused as default. You can use the following command to achieve this:

display.setCurrentItem(item);

where 'display' is a reference to the midlet diapay and 'item' is the component to focus upon.

Something I would like to know, is how to force an form component to retain focus. (ie, so a user cannot press the up/down arrows, changing the focus of a component). I can manage this using a customitem and overriding the traverse method, but can't do this with standard components, such as textfields.

Or perhaps this is asking a bit much! Any ideas??!

nice pervasiveapp, I though there was a way

with your dilemma, it sucks their is no lostfocus, focus changed, onchange methods, like there are in other languages
