Deployed EhLib 4.2
+ Added support of Delphi 2007.
In DBGridEh
+ Added IndicatorTitle property of TDBGridEhIndicatorTitle type:
The Upper left cell can react as button, draw the badge-triangle, and display
the dropdown menu on mouse clickling ( with possibility of drawing global menu,
which adjust using global property - DBGridEhCenter.IndicatorTitleMenus and
IndicatorTitleMenus.OnBuildIndicatorTitleMenu).
IndicatorTitle property
has a next subprotperty:
DropdownMenu: TPopupMenu - The Local dropdown menu, appearing when you
press the upper left cell of the grid.
ShowDropDownSign: Boolean - Specifies whether to draw the badge-triangle.
You can set this property to show that the pressing on upper-left cell will
show the droped down menu.
TitleButton: Boolean - Specifies whether the upper left cell will act
as button. Besides the DropdownMenu will be droped down only when TitleButton
= True.
UseGlobalMenu: Boolean - Specifies whether the global DBGridEhCenter.IndicatorTitleMenus
property will be use when building menu.
Added OnIndicatorTitleMouseDown
event. Occurs when the mouse click on the upper left cell of grid. The Cell
must be adjusted in state of working as buttons (IndicatorTitle.TitleButton
= True). You can call DefaultIndicatorTitleMouseDown
method in this event to pass control to a global object - DBGridEhCenter.
Added OnBuildIndicatorTitleMenu event. Occurs when need to build list of menus before menu is shown. You can call DefaultBuildIndicatorTitleMenu method in this event to pass control to a global object - DBGridEhCenter.
Added OnCellMouseClick
event. Occurs when mouse click in any cell of grid.
Event pass coordinates of the cell and offset of the mouse for upper left corner
of the cell. You can call DefaultCellMouseClick method in this event to pass
control to a global object - DBGridEhCenter.
+ In module DBGridEh.Pas appeared the new global object DBGridEhCenter of TDBGridEhCenter
type. This object is intended to manage a behaviour of all objects of TCustomGridEh
type or inherited from it. For instance, in DBGridEhCenter you can specify the
list a menu to be appearing in the drop-down menu of the all grids when clicking
on top left grid cell. Besides, you may write the event of this global object
and it will be caused at activations of the similar event in any grid of the
project.
Global object
- DBGridEhCenter has a following properties and events:
IndicatorTitleMenus: Is the list of menu, which will be formed when clicking
on upper left cell of grid is occured. This property of the global object will
work for all grids, which IndicatorTitle.TitleButton = True. (itmVisibleColumnsEh,
itmCut, itmCopy, itmPaste, itmDelete, itmSelectAll).
OnBuildIndicatorTitleMenu: Occurs when need to build list of menus before
menu is shown.
OnCellMouseClick: Occurs when mouse click in any cell of grid.
OnIndicatorTitleMouseDown: Occurs when mouse click upper left cell of
grid.
+ Added global
variable - DBGridEhCenter. This variable controls the part of behaviour of the
grids. You can set properties, or events of this variable to change the behaviour
of all grids.

When cursor reside in the filter cell they can press ENTER to apply filter.
For automatically
filtering data in dataset need to add one of the units EhLib... (EhLibADO, EhLibBDE,
EhLibCDS) to 'uses' clause of any unit of your project. Now EhLib have objects
to filter data in the TClientDataSet, TQuery, TTable and TADOQuery. You have
to write and register your own object to filter
data in DataSet that not present in this list or you can write TDBGridEh.OnApplyFilter
event for every grid.
Added property
- STFilter: TSTDBGridEhFilter with subproperties:
property Local: Boolean - grid does not
use it, but object that perform filtering can determine whether it will filter
locally in dataset or on the server (by adding filter expressions in SQL 'WHERE'
clause).

Library is divided to design-time and run-time packages.
EhLib[XX] - run-time package and DclEhLib[X] - design-time packages, where
[XX] is digit number of VCL version:
[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.
New componetns: TPropStorageEh, TIniPropStorageManEh, TRegPropStorageManEh.
Components realize technology to store components properties to/from settings
storage such as ini files, registry etc.
