Re: [codenameone-discussions] Re: Trying to use third party lib (PubNub) to handle messaging

There is also a WebSocket sample in the SampleRunner
https://github.com/codenameone/CodenameOne/tree/master/Samples

The sample (a chat app), should run out of the box. Just download the CN1
sources, open the Sample Runner (instructions at link above), and click
"Launch" next to the WebSocketSample.

[codenameone-discussions] Re: AutoCompleteTextField NullPointerException

[Shai Almog]

Did you remove the auto-complete component (or one of its parents) from the 
form dynamically?

[codenameone-discussions] Re: how to render TextArea or textField to vary font and color within the body of text

[Dave Dyer]

Text is an interface that mostly mimics strings, but it's part of a group 
of interfaces I use to build my GUIs, not something
you could just pull out and plug into your applications.  You have to take 
the whole village, and I haven't engineered the
villiage for export and general use.   

The key things are that Text has string-like methods such as "append" and 
"getWidth", and interfaces with a canvas proxy
that supports things like"draw".  I produce widgets that look like this 
using Text objects, using essentially the same logic that
was once based on strings.

[greensoter]

Where can I get the Websockets document and sample code? Then I can 
implement in my app as well, thanks!

[shop . service . assistant]

Can you share the "text" Object and some examples of use?

It would be great if I were able to use mixed text fonts colors and icons.

Thanks in advance,

Regards.
