EhLib 6.2 is available for download

+ DropDownForms technology - customizing droped down windows.

Typical DropDown window - is the list that appears in the TComboBox control when you click on the edit button with down arrow in the control.
New technology of DropDropForms allows you to create forms that appear and work similarly to the drop down list of TComboBox. These forms can be displayed by pressing one of the edit buttons within controls TDBEditEh, TDBNumberEditEh, TInplaceEditor in DBGridEh etc.

See detailed description of using DropDownForms in the document <About EhLib 6.2 Eng.doc>; Section - DropDownForms

and See an Example in the:

<EhLib Archive>\Demos\DropDownForm\Project1.dpr

compiled project:

<EhLib Archive>\Demos\Bin\DropDownForm.Exe

New properties to customize the drop-down Form are in the following classes:

(For DBGridEh)

TColumnEh.DropDownFormParam
TColumnEh.EditButtons[i].DropDownFormParam

(For DBVertGridEh)

TFieldRowEh.DropDownFormParam
TFieldRowEh.EditButtons[i].DropDownFormParam

TDBEditEh.EditButton.DropDownFormParam
TDBEditEh.EditButtons[i].DropDownFormParam

 

In EditButtons for TDBNumberEditEh, TDBDateTimeEditEh, TDBComboBoxEh, TDBLookupComboBoxEh controls.

 

(In DBVertGridEh)

+ Added possibility to group rows into categories. See TDBVertGridEh.RowCategories property.

Assign category name in the property TFieldRowEh.CategoryName.
The rows can be grouped by: Category Title, Field Type or presence/absence of values in the current record.

+ Added possibility to sort the rows by the row captions. See property TDBVertGridEh.RowsSortOrder.

 

(In DBGridEh)

+ In DBGridEh at Design-Time it is allowed to create DB components and assign DataSource and DataSource.DataSet properties. Right-click above the Design-Time panel in the lower right corner of the Grid and select the menu to assign or create a required component.

 

(In TIniPropStorageManEh)

* In the TIniPropStorageManEh.WritePropertiesText method the class that is used to write data to a file is changed. Instead of TIniFile the TMemIniFile is now used. It accelerated the write operation to the file, but changed the location of the file when IniFileName property is not specified a full path. The new version of the file will be saved in the current directory instead of the WINDOWS directory.

EhLib 5.6 is available for download

* Fixed handling of the global variable OldStyleFlatBorder. In previous versions, if OldStyleFlatBorder = False (default value is False), then if TDBEditEh.Flat = True then drawing boundaries of TDBEditEh in Flat style never worked. In this version, if OldStyleFlatBorder = False then drawing boundaries of TDBEditEh in Flat style will work when the Windwos is in the Classic style and drawing Flat border will not work when the Windwos is in Themed environments and application use Themes.

+ Added a Images property in the class TEditButtonEh (TDBEditEh.EditButtons[i].Images) of a TEditButtonImagesE type.

TEditButtonImagesEh = class(TPersistent)
published property NormalImages: TCustomImageList;
property HotImages: TCustomImageList;
property PressedImages: TCustomImageList;
property DisabledImages: TCustomImageList;
property NormalIndex: Integer;
property HotIndex: Integer;
property PressedIndex: Integer;
property DisabledIndex: Integer;
end;

Now it is allowed to draw Images from ImageList in EditButtons of Edit controls and columns of TDBGridEh. Images are drawn when TEditButtonEh.Style = ebsGlyphEh and TDBEditEh.EditButtons[i].Images.NormalImages is assigned.

+ Added EmptyDataInfo property in DBGridEh. If this property is enabled and DataSet is Active and it contains no data, then DBGridEh draws <No data> text in the center of the client area. You can specify the inscription for each DBGrid or set a global variable DBGridEhEmptyDataInfoText that is located in the module DBGridEh.

+ Added EmptyDataInfo property in the TDBEditEh, TDBNumberEditEh, TDBComboBoxEh, TDBLookupComboBoxEh. Use TDBEditEh.EmptyDataInfo.Text property to display the text that will be displayed in the Edit control when it contains no data.

+ Added standart property Touch (supported in Delphi 2010 and higher) for DBGridEh, TDBEditEh, TDBNumberEditEh, TDBComboBoxEh, TDBLookupComboBoxEh, TDBDateTimeEditEh.

+ Added the ability in design-time to open the Edit buttons collection editor (EditButtons) in TDBEditEh, TDBNumberEditEh, TDBComboBoxEh, TDBLookupComboBoxEh, TDBDateTimeEditEh controls. A menu item to open the collection is in the context menu of the component that opens on the right mouse button.

+ In TDBCheckBoxEh added the ability to set Empty value ('') for properties ValueChecked, ValueUnchecked. This allows you to set the state of CheckBox for Null value of DB field.

+ In DBGridEh added OnDataGroupGetRowParams event. The event is used to customize information for group records (when Grid works in data grouping mode - Grid.DataGrouping.Active = True). In the event you can specify color, font, text and pictures for the group row.

+ In the module DBGridEhImpExp added a global procedure - ExportDBGridEhToOleExcel. The procedure is designed to export data from DBGridEh to MS Excel. The procedure uses OLE to export data which means the MS Excel must be installed on the computer to allow this procedure work.

+ At design-time a context menu of TDBGridEh component displays information about the version of the library. + Added global procedure - DrawProgressBarEh. The procedure allows you to draw a picture in the form of a progress bar (ProgressBar). It can be used to display progress bar in grid cells. See example of use in the DEMOS\DEMO1 project.

EhLib 5.5 is available for download

+ Added support of Embarcadero RAD Studio XE2.

+ ThemeTitleFillElement property add to the TDBGridEhStyle class. property ThemeTitleFillElement: TGridThemeTitleFillElementEh; TGridThemeTitleFillElementEh = (gtfeHeaderItemEh, gtfeSplitButtonEh); This property defines Themes element that will be used to fill the background
the grid titles when property TDBGridEh.Flat = False.

* TDBGridEh.Flat property has no effect of filling of then title background under RAD Studio XE2 when TStyleManager.IsCustomStyleActive is True. In this case the grid fills titles using Themes style that is defined by DBGridEhDefaultStyle.ThemeTitleFillElement property.

* The filling of the grid titles uses thHeaderItem Theme style rather then ttbSplitButton style from version EhLib 5.5. Set global property DBGridEhDefaultStyle.ThemeTitleFillElement to gtfeSplitButtonEh for filling the title in the old style.

20 May 2011

EhLib 5.4 is available for download

+ In DBGridEh. Checkboxes can be shown in the indicator column. Checkboxes is used to select records in the Grid.

gioShowRecNoEh - have same meaning as dghShowRecNo in OptionsEh.
gioShowRowselCheckboxesEh - show checkboxes in the indocator column.

+ In MemTableEh. The principle of storing data for Calculated and Lookup fields was changed. Now values of these fields are stored in a special buffer for each record, and they are not recalculated each time when the data in the grid is repainted or scrolled. It allows to increase speed of showing data of Lookup and Calculated fields in the DBGridEh.

* Changes in the MemTableEh. If the MemTableEh is connected to DataDriver and fields are created in Design-Time (as Persistent Field Components),
then the MemTableEh creates internal structure of records taking description from Persistent Fields rather than taking structure from the DataDriver.

20 October 2010

EhLib 5.3 is available for download

+ Added support of Embarcadero RAD Studio XE

+ Added Options property in MemTableEh of TMemTableOptionsEh type.

[40] for Delphi 4, [50] for Delphi 5, etc; And EhLibB[XX] with DclEhLibB[XX] for C++ Builder.

Upon installation, all components is placed to the separate page in components palette with name - 'EhLib'.
Note that Delphi IDE does not move components to the new default place when you install new version of same component(s). So if you already has EhLib installed, then installation new (3.0) version does not move EhLib components to the 'EhLib' page on components palette. To force Delphi IDE to move compontes to the default place on components palette do next:
Open menu: Component->Configure Palette.
Select '[All]' line in Pages listbox.
Click 'Default Pages' button.
