Overview
--------
The Library contains several components and objects.
TDBGridEh component
TDBGridEh provides all functionality of TDBGrid
and adds several new features as follows:
Allows to select records, columns and rectangle areas.
Special titles that can correspond to several/all columns.
Footer that is able to show sum/count/other field values.
Automatic column resizing to set grid width equal client width.
Ability to change row and title height.
Allows automatic broken of a single line long title and data row
to a multiline.
Title can act as button and, optionally show a sort marker.
Automatically sortmarking.
Ability to truncate long text with ellipsis.
Lookup list can show several fields.
Incremental search in lookup fields.
Frozen columns.
DateTime picker support for TDateField and TDateTimeField.
Allows to show bitmaps from TImageList depending on field value.
Allows to hide and track horizontal or vertical scrollbars.
Allows to hide columns.
Allows to show 3D frame for frozen, footer and data rows.
Allows to draw memo fields.
Multiline inplace editor.
Proportional scrolling independently of sequenced of dataset.
Automatically show checkboxes for Boolean fields. Allows to show
checkboxes for other type of fields.
Has a procedures to save and restore layout (visible columns, columns
order, columns width, sortmarkers, row height) in/from registry or ini file.
Allows to show hint (ToolTips) for text that don't fit in the cell.
Allows to export data to Text, Csv, HTML, RTF, XLS and internal formats.
Allows to import data from Text and internal formats.
Can sort data in various dataset's.
Can filter data in various dataset's.
When DBGridEh is connected to DataSet of TMemTable type it allows:
To view all data without moving active record.
To display a tree-type structure of TMemTable records.
To form list of values in dropdown list of SubTitle filter automatically.
TDBLookupComboboxEh component
Provides all functionality of TDBLookupCombobox and adds
several new features as follows:
Can have flat style.
Allows assign values as to KeyValue property just and to
display Text property.
Allows to type (assign) values to Text property not contained in data list
(Style = csDropDownEh).
Allows to hold KeyValue and Text as not affecting to each other values.
Take effect when KeyField, ListField, ListSource, DataField and DataSource
properties is empty.
Drop down list can:
Show titles,
Have sizing grip,
Automaticaly set width as sum of DisplayWidth of the list fields (Width = -1),
Automaticaly drops on user pressed the key.
Edit button can:
Show DropDown, Ellipsis or Bitmap image.
Have specified width.
Have additional events: OnKeyValueChanged, OnButtonClick.
TDBSumList component
This component is intended for totaling sums and amounts of records in a
TDataSet with dynamic changes. Component keeps a list of TDBSum
objects, which contains types of group operations (goSum or goCount)
and name sum field (goCount name of field is unnecessary).
TPrintDBGridEh component
TPrintDBGridEh provides properties and routines for preview and
print of TDBGridEh component with several features:
Ability to expand rows vertically until all text is printed.
Ability to scale grid to fit it to page width.
Ability to print/preview title for grid.
Ability to print/preview page header and page footer where you can
specify macros for current page, current date, current time and/or static
text.
Automatically print/preview multiselected area of TDBGridEh if it area
is not empty.
Ability to print/preview rich text before and after grid.
TPreviewBox component
TPreviewBox lets you create a customizable runtime preview.
TPrinterPreview object
TPrinterPreview lets you to record printable data in buffer for following
output them on screen and to printer. TPrinterPreview have all functions and
properties as in TPrinter object. You can use TPrinterPreview object similarly
of TPrinter except some details. In TPrinter Printer.Canvas.Handle and
Printer.Handle is the same but in TPrinterPreview PrinterPreview.Canvas.Handle
represent the metafile in that is recored the data and PrinterPreview.Handle
represent Printer.Handle. That is mean that you have to use
PrinterPreview.Canvas.Handle for draw operation (DrawText, DrawTexteEx, e.t.c.)
and use PrinterPreview.Handle in functions that return information about
printer facilities (GetDeviceCaps, e.t.c.). Global function PrinterPreview
returns default PrinterPreview object and shows data in default preview form.
TDBEditEh component
represents a single or multi-line edit control that can display and edit a field
in a dataset or can works as non data-aware edit control.
TDBDateTimeEditEh component
represents a single-line date or time edit control that can display and edit
a datetime field in a dataset or can works as non data-aware edit control.
TDBComboBoxEh component
represents a single or multi-line edit control that combines an edit box
with a scrollable list and can display and edit a field in a dataset or can
works as non data-aware combo edit control.
TDBNumberEditEh component
represents a single-line number edit control that can display and edit a numeric
field in a dataset or can works as non data-aware edit control.
TPropStorageEh, TIniPropStorageManEh, TRegPropStorageManEh components
Components realize technology to store component properties to/from settings
storage such as ini files, registry etc.
TMemTableEh component
dataset, which hold data in memory. Its possible consider as an array of
records.
Besides, it:
Supports a special interface, which allows DBGridEh component to view all
data without moving active record.
Allows fetch data from TDataDriverEh object (DataDriver property).
Allows unload change back in DataDriver, operative or postponed (in
dependencies of the CachedUpdates property).
Allows to create a master/detail relations on the client (filtering record)
or on the external source (updating parameters [Params] and requiring data
from DataDriver).
Allows once-only (without the dynamic support) sort data, including
Calculated and Lookup field.
Allows create and fill data in design-time and save data in dfm file of the
Form.
Allows keep record in the manner of trees. Each record can have record
elements-branches and itself be an element to other parental record.
Component TDBGridEh supports to show the tree-type structure of these
records.
Allows to connect to the internal array of other TMemTableEh (via
ExternalMemData property) and work with its data: sort, filter, edit.
Has interface for requesting list of all unique values in one column of
records array, ignoring local filter of the DataSet. TDBGridEh uses this
property for automatic filling a list in DropDownBox of the subtitle
filter cell.
TDataDriverEh component
carry out two tasks:
Delivers data to TMemTableEh.
Processes changed records of TMemTableEh (writes them in other dataset,
or call events for pro
