HI all,

Please whats the equivalent of JTextArea in Blackberry API?

Thanks,

Dan

LabelField most likely. there are some other fields that provide added functionality, like RichTextField, Active... etc

[dankolix]

really? LabelField? I thought that was just for adding labels..

Sorry for not making myself very clear. What I am trying to do is make a simple chat program that looks like this (pictures are worth Kilo-words)

send and quit are buttons..

I want to have a text window for both the editfield and the TextArea. So when you type in the editfield and click send, it appears on the TextArea(which is not editable).

If i was using normal Java SE i would use JTextArea for both. What is the equivalent of that in BB? excuse the oversimplification ;-)

[simon_hain]

i have used a listfield for the text area. each message is an object in the listfield.

another option would be to add one labelfield per message.

or use a labelfield for the whole area.

a labelfield is just a field to display text.

[dankolix]

i get what you mean simon, but i want it to look like a proper conventional JTextArea (chat window) with a whilte background and some border around it, without making the whole Screen have a white background.

[simon_hain]

a textfield has no background per se. you have to overwrite paintbackground to create one.

[titakalpesh]

Hi,

for that you have to create a custom FieldMenager that has the border then you can add the label to it so it will become same like chat area.

Thanks,

Tita

thanks titakapelsh,

One more thing, How do i make it scorllable? is there any properties in the FieldManager that would make it scrollable? or do I have to overwrite something again and draw the scrollbars myself? hope not

[simon_hain]

i use a verticalfieldmanager with scrollable style.

[titakalpesh]

Hi,

as simon said you can set the style property see below code.

VerticalFieldManager fieldManager2 = new VerticalFieldManager(VerticalFieldManager.VERTICAL_SCROLL);

and if you get it's working please mark it as solved

Thanks

Tita
