Specification

EhLib.VclFmx component library - Software specification

Software type:

EhLib.VclFmx is a library of components, classes, and functions for Delphi, C++ Builder, and Lazarus.

Purpose

EhLib.VclFmx provides a comprehensive set of interactive UI controls and in-memory data structures created to help developers build professional UI applications that work with databases.

The library is designed to simplify the development of applications where end users can efficiently view, edit, process, and manage data.

Key Features

The library allows developers to:

  • View database query results using flexible tabular and visual controls
  • Load, store, and manipulate data in memory (e.g., using TMemTableEh) for further processing and display
  • Interactively edit and input data, which can then be saved back to a database or other storage systems
  • Sort, filter, group, and search data efficiently using the Vcl.TDBGridEh and Fmx.TDataGridEh controls
  • Print and preview the current state of controls
  • Export data to multiple formats, including PDF, XLS, XLSX, RTF, and TXT

Editions

The Professional (Source codes included) edition contains the source code of the library. The source code is written in Delphi (Object Pascal) language.

EhLib.VclFmx Standard (Without source codes)

The Standard (Without Source Code) edition includes only the compiled binary files of the library for the Windows 32-bit and Windows 64-bit platforms.

This edition does not include design-time packages for the RAD Studio IDE (64-bit).

In addition, the Standard (Without Source Code) edition has the following limitations:

  • No Lazarus binaries. The EhLib Without Source Code edition does not support the Lazarus IDE.
  • No BDE DataDriver packages. The binary files of the EhLibBDEDataDrivers and DclEhLibBDEDataDrivers packages are not included, therefore the TBDEDataDriverEh component is unavailable.
