Unable to make LWUIT Textarea to grow by content

[ChinLoong]

I am using LWUIT for the Series 40 below.

http://projects.developer.nokia.com/LWUIT_for_Series_40

Below is my code for using the LWUIT textarea.

//Set textarea row to 1, and column to 10
title = new TextArea("The quick brown fox jumps over the lazy dog",1,10);
title.setSingleLineTextArea(false);
title.setGrowByContent(true);
title.setEditable(false);

The textarea does not grow, even though my string requires more than 1 line to be displayed completely.

However, if I pass 2(for row argument) into the textarea constructor, the textarea will grow to show the string completely.
My problem with setting row to 2 is if the string is only 1 line, the textarea will still display an additional empty line, which I want to avoid.

May I know, how I can solve this issue? Thanks in advance.

Hi ChinLoong,

s40 version of LWUIT has this problem. I reported to RnD team. Thanks for bringing this issue up.

Excellent! Thanks for looking into the issue.

Till the time this Issue is fixed (automated), as a workaround you can try to calculate the length of String which you want to render in the textArea by using charsWidth(char[]) with the used Font and based on this define the no. of rows.

Yes, this is a very useful workaround. Thanks!

it's useful on static case, but when it's dynamic , I have no good solution

For Dynamic you do these calculation and runtime and repaint after changing the TextArea size.... as text grows.

Use setFocus() to move the focus to some other component on the screen or move to another form by calling its show().

it seems first method doesn't work. second not suitable for the scene。
