Custom List

[Ofer Gurman]

Does anyone know of a custom item which implements a custom list?

O Gur,

Please change your display name to conform to the JavaRanch naming policy, which you had agreed to when you signed up.

thanks.

Oh sorry.
Back to my question, can you help me please, I need to write a custom item that implements a list behavior (MUST support text wrapping). I have succeeded in most parts of the custom item but for the text wrapping.

Thanks,

Ofer.

Hi Ofer,

There is no component or class that provides what you need in MIDP. I also had to do something like that. For the text-wrapping part I wrote a function that takes a string and divides it into lines based on the width available.

What you need is Canvas.getWidth() to see what is the maximum width of the screen and then Font.getCharWidth() to find out how many chars can you have in one line. You should also check for whitespace to break on word boundary.

Ofer,

Your name still does not conform to the requirement. Please read the link I provided above. You need a first name and a last name.

In MIDP 2, the Choice.TEXT_WRAP_DEFAULT variable controls whether the item wraps text. There is no need for a custom item.

Ups, I have missed this one. Always good to learn something new, though.
