ExpressQuantumTreeList is Now Available

DevExpress is happy to announce the immediate availability of the ExpressQuantumTreeList v4, our 100% VCL Tree/List component library for Delphi and C++Builder. The ExpressQuantumTreeList represents the most advanced tree-list technology available for VCL developers. The ExpressQuantumTreeList is a power-packed component library that will help you create killer applications, deliver unbelievable features to your end-users, and blow away your competition - all without writing a single line of source code!

Blazing Fast!

Powered by the same architecture and shared libraries first introduced in the ExpressQuantumGrid 4, ExpressQuantumTreeList ships with all the features you have come to expect from DevExpress. It supports our industry leading Look And Feel and Style Controller technologies - and ships with the ExpressEditors Library 4.

The QuantumTreeList can be used in 3 different data access modes: Data Aware, Unbound and Virtual. Whichever mode you choose to use, the QuantumTreeList employs our unique DataController library to obtain and save data at lightening speeds. In virtual mode, the QuantumTreeList does not persist data and so displaying hundreds of thousands of nodes on screen occurs instantaneously!
