What's new in EhLib.VclFmx 12.0

Introduction

The EhLib.VclFmx 12.0 library includes all the components and functionality of the EhLib.VCL library version 11.1. However, to separate the functionality into platform-independent and platform-dependent on the Win32/Win64 platform, the following changes were made to EhLib.VclFmx 12.0:

The EhLib.VCL 11.1 library included one main package EhLibXXX.bpl which contained components and controls compatible with the VCL core library.

The EhLib.VlcFmx 12.0 library includes three main packages:

• EhLibRtl cross-platform package compatible with the Embarcadero base library – Rtl (Run-time library). Contains such non-visual components as TMemTableEh, TDataSetDriver, etc. The package can compile under Win32, Win64, Android32, Android64, iOS64, OSX64, Linux64 platforms.

• EhLibVcl package of visual components for the Win32, Win64 platform compatible with the basic VCL library. The package includes all visual components that were included in the EhLib 11.1 library, including the TDBGridEh component.

• EhLibFmx a package of visual components for the Win32, Win64, Android32, Android64, iOS64, OSX64, Linux64 platforms compatible with the FireMonkey (Fmx) base library. At the moment, the library includes one visual component – TDataGridEh.

The original pas files from the EhLibRtl and EhLibVcl modules remained compatible with the LCL base library of the Lazarus software environment.

Support for RAD Studio 2009 has been removed. The minimum supported version of RAD Studio is RAD Studio 2010.

The multi-platform graphics package EhLibFmx is available in RAD Studio 11.3 and higher.

EhLib.VCL software renamed to EhLib.VclFmx.

Changes in names of modules (pas, dcu files), classes and methods.

• The EhLibVcl module is divided into two modules - EhLibVclUtils and EhLibUtils. The EhLibVclUtils module has been moved to the EhLibVcl package and contains methods and classes tied to the VCL graphics library. The EhLibUtils module has been moved to the EhLibRtl package and contains methods and classes independent of the graphics framework.

• Module EhLibMTE.pas renamed to EhLibVclMTE.pas

• Module EhLibADO.pas renamed to EhLibVclADO.pas

• Module EhLibBDE.pas renamed to EhLibVclBDE.pas

• Module EhLibCDS.pas renamed to EhLibVclCDS.pas

• Module EhLibDBX.pas renamed to EhLibVclDBX.Pas

• Module EhLibFIB.pas renamed to EhLibVclFIB.pas

• Module EhLibFireDAC.pas renamed to EhLibVclFireDAC.pas

• Module EhLibIBX.pas renamed to EhLibVclIBX.pas

• A new module DBGridEh.DBUtils has been added to the EhLibVcl package. The classes TDatasetFeaturesEh, TSQLDatasetFeaturesEh, TCommandTextDatasetFeaturesEh and the procedures RegisterDatasetFeaturesEh, GetDatasetFeaturesForDataSet, DefaultLocateDatasetTextEh, ApplySortingForSQLBasedDataSet, ApplyFilterSQLBasedDataSet, GetExpressionAsFilterString from the DBUtilsEh module have been moved to this module.

• The TDatasetFeaturesEh class has been renamed to TDBGridDatasetFeaturesEh.

• Класс TSQLDatasetFeaturesEh renamed to TDBGridSQLDatasetFeaturesEh.

• The RegisterDatasetFeaturesEh procedure has been renamed to RegisterDBGridDatasetFeaturesEh.

• The GetDatasetFeaturesForDataSet procedure has been renamed to GetDBGridDatasetFeaturesForDataSet.

• In Lazarus projects, references to the DBGridsEh module must be renamed to DBGridEh. The original DBGridEh.pas module is no longer renamed to DBGridsEh.pas when porting packages to Lazarus.

• The EhLibInstaller application now has the ability to uninstall the library from the RAD Studio IDE.

What's new in EhLib 12 Vcl section

• The DataSource property type has been changed in the TDBGridEh control. Now this property has the TComponent type and components of the TDataSource or TDataSet type can be assigned to this property. To link the TDBGridEh control and TDataSet, you do not need the intermediate TDataSource component. Assign your DataSet (TQuery, TFDQuery) to the TDBGridEh.DataSource property.

• Due to the change of the TDBGridEh.DataSource property type to the TComponent type in your project, you need to change the references of the DBGridEh1.DataSource.DataSet type to DBGridEh1.DataSet or to the DBGridEh1.DBDataSource.DataSet string. The DataSet property of the TDataSet type has been added to TDBGridEh, which refers to the DataSet that is in the DBGridEh-DataSource-DataSet chain. If you need to get a reference to the DataSource that is an instance of the TDataSource class, use the TDBGridEh.DBDataSource property.

What's new in EhLib 12 Fmx section

• Added new package - EhLibFmx.
• Added new component - Fmx.TDataGridEh.
