Reference for unit 'LCLVersion'

Contains the version number constants of the LCL.

Overview

The LCLVersion unit contains the version number constants of the LCL. They can be used at runtime to determine the LCL version, so LCL application writers and component writers can offer different functionality or workarounds for bugs and take the LCL version into account while choosing their algorithms at run-time.

Likewise, these version constants can be used at compile time in an conditional expressions, such as {$IFDEF lcl_major>0}. Currently these kinds of epressions are only support in {$mode delphi}. Recently fpc 2.3.1 added support for these kind of expressions in {$mode objfpc}.
