The last officially released package can be downloaded from the Lazarus CCR SourceForge site.

Note, however, that this version is quite outdated. A newer and maintained version is available via the Online Package Manager which is available in newer versions of Lazarus.


The component is available on Lazarus CCR's svn repository:

 svn co https://svn.code.sf.net/p/lazarus-ccr/svn/components/rx

Dependencies / System Requirements

Tested on Linux. Changes to be made:

  • Canvas.BrushCopy is used. You should replace this with a call to Canvas.CopyRect.
  • Add Types to the uses in rxdbgrid.pas and rxtoolbar.pas

An updated version will be posted as soon as possible.


  • Place sources in any directory.
  • Go to menu "Packages" -> "Open Package File (*.lpk)". Navigate to the folder containing the rx sources.
  • At first open package "rxtools.lpk". Compile.
  • Then open rxnew.lpk. Compile the component to verify that everything is ok. Install and let Lazarus rebuild.
  • There are several addon packages. Install them only if you need them. They depend on other packages which must be installed first.


If someone knows how the authors can be contacted, please tell us. My russian is not too good.
