How to set the control in TvirtualStringTree

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Editors IDEs

Delphi is the most powerful Object Pascal IDE and component library for cross-platform Native App Development with flexible Cloud services and broad IoT connectivity. It provides powerful VCL controls for Windows 10 and enables FMX development for Windows, Mac and Mobile. Delphi is your choice for ultrafast Enterprise Strong Development™. Look for increased memory for large projects, extended multi-monitor support, improved Object Inspector and much more. Delphi is 5x faster for development and deployment across multiple desktop, mobile, cloud and database platforms including 32-bit and 64-bit Windows 10.
