Rapid Solutions is a shareware library that works with Delphi and C++ Builder, leveraging RapidTree and FlyTreeview RE. This powerful software provides a range of capabilities for users.

One of the standout features of Rapid Solutions is RapidTree - which boasts the title of fastest tree in the world. Meanwhile, FlyTreeView RE is an even more powerful tree control, with a superset of features and abilities. The Polymorphic TTreeCollection is also worth highlighting - this is a collection that comes with a hierarchical structure and polymorphic streaming system.
The library includes a range of other controls, too. CheckedGroup controls include CheckedGroup, CheckedOptionGroup, CheckedCheckboxGroup, and CheckedEdit. Meanwhile, the RapidEditor control comes in four different styles: Simple, Dropdownlist, DropdownChecklistbox, and DropdownTree. File controls like DropDownFoldersTree and RapidExplorer are also included.
When working with Rapid Solutions, you'll have access to the runtime IDE PropertiesTree - a runtime property editor. And while the library is already packed with features, there are even more expected in future versions. These will include more integration with the runtime IDE PropertiesTree and the most advanced property editors around. Additionally, DropdownFoldersTree and RapidExplorer will become even more powerful and flexible, and new controls like PopupFlyTreeview and DropDownFlyTree are set to be added.
