Most needs can be satisfied with native widgets, but emulated widgets help fill in the gaps and allow you to completely take control of the look and feel of your user interface.
Graphic Acceleration
DirectWrite and GPU acceleration are utilized within the editors on Windows.
Communications & Web Dev
Web Services Tools
A self-contained, modular framework for accessing and hosting Web Services with tools for creating and deploying them.
Server Smalltalk (SST)
SST is a flexible communications framework that is the foundation of many VAST protocol implementations including distributed garbage collection, logical processes, web services, HTTP, SMTP, and IMAP.
Integrated Web Technology
Inclusion of the Seaside web framework, REST, HTTPS, jQuery, AJAX, and several other web development technologies and tools will get your web project off the ground quickly.
Network Protocol Support
Powerful HTTP, IMAP, SMTP, FTP/FTPS, IBM MQ series, MQTT, and LDAP/LDAPS clients are all included for superior connectivity with a powerful sockets API including full support for TCP/IP V4/V6 protocols.
External Interface Support

Streamed HTTP Retrieval
Using our asynchronous streams functionality, retrieve large pieces of streamed HTTP content, and asynchronously process these large files in smaller pieces for improved efficiency.
MQTT Client
MQTT is a lightweight communication protocol that’s a close relative of IBM® MQSeries. Support for version 3, 3.11, and 5 protocols are included, and asynchronous streams are already integrated for easy consumption of publish/subscription updates.
Databases
