From RxLib to JVCL in details. List of lost properties and methods of Rx components.

June 28th, 2011 No comments

The original post in Russian can be found here: Переход с RxLib на JVCL в деталях. Список пропавших в JVCL свойств и методов Rx-компонентов.

My previous post doesn’t provide full information about differences between RxLib and JVCL components. So here is full list of all public and published properties and methods, which are missing in JVCL-components. For every component.

Ante Scriptum: I definitely like new RTTI in Delphi 2010. =)

I created small program that compares properties and methods for each component using Delphi 2010 RTTI.

Program has 3 units:

  • uRxJvComponents.pas – contains list of Rx and Jv classes. Creating this list was the only unpleasant part of this work.
  • uCompareClasses.pas – class that compares Rx and JVCL components.
  • RxJvCompareMainFormU.pas – main form. Can run comparison and show results in text/html format.

You can download: Rx and Jvcl Compare util.zip here

Remark: program can be compiled in Delphi 2010+. To compile you need to install both RxLib and JVCL.

Going from RxLib to Jvcl. What was changed?

June 25th, 2011 Comments off

This is translation of my post in Russian: Переход с RxLib на JVCL. Какие изменения? Original post was published in February 2010.

This article is written for those developers who still uses RxLib library in non-unicode Delphi and is thinking about going to Unicode.

In year 2002 RxLib was officially merged with Jedi Visual Component Library. JVCL has special tool for rapid conversion of all Rx components, functions and units to according JVCL code. See previous post Jvcl Dev Tools: JvclConvert.

Why not to stay with RxLib, and move to JVCL?

  1. JVCL is maintained. Bugs are fixed. You’ll always have JVCL version with newest Delphi IDE support.
  2. RxLib is abandoned. There are few enthusiasts who try to release patches, but they are not coordinated. Most of existing RxLib versions for Delphi 2009, 2010 and XE has its own unique code changes. Most of them have bugs either. Even version that was released in “official” RxLib project on SourceForge has bugs.
  3. JVCL supports Windows themes, RxLib is not.

This post contains list of all Rx components with according Jvcl component, package name, and short list of differences. You can find more detailed list in the next article “From RxLib to JVCL: details”.
