bool Match ( const Common::CFormat * format ) const [virtual]

Indicates whether a reflector matches to the specified format.

The reflector matches only to __int64-type format which presents date or time.

Parameters:

[in] format A textual format to verify whether a reflector matches to.

Returns:: True if the reflector matches to the format. Otherwise false.

Implements IControlReflector.

bool CreateAndAttachControl	(	CEditInPlaceContext &	context,
		const Common::CFormat *	format,
		IEditInPlace::StartReason	startReason
	)			`[virtual]`

Creates datetime MFC control.

Creates MFC control of CEmbeddedDateTimeCtrl type and initializes it with the parameters, returned by the format.

Parameters:

`[in]`	context	Indicates the cell, where the control should be attached.
`[in]`	format	Format object, that permits to populate MFC control.
`[in]`	startReason	Indicates the reason, why MFC control should be created.

Returns:: true if MFC control has been successfully created.

Implements IControlReflector.

bool CanStopEdit	(	const CEditInPlaceContext &	context,
		IEditInPlace::StopReason	reason
	)			const `[virtual]`

Indicates whether CGrid can stop edit in place in the control.

Parameters:

`[in]`	context	Indicates the cell, where the control is attached.
`[in]`	reason	Indicates the reason, why the control should be detached and then destroyed.

Returns:: True if edit in place can be stopped. Otherwise false.

Implements IControlReflector.

bool Apply	(	CEditInPlaceContext &	context,
		const Common::CFormat *	format
	)			`[virtual]`

Applies the new value set by user in MFC control to the specified field in the data object.

Parameters:

`[in]`	context	Indicates the cell, where the control is attached.
`[in]`	format	Format object, that permits to transform the formatted value in MFC control to an unformatted form and then set it into the appropriated field of the data object.

Returns:: True if the value has been successfully set into the appropriated field of the data object.

Implements IControlReflector.

bool DetachAndDestroyControl	(	CGrid &	grid,
		HITEM	hItem,
		const CColumn *	column
	)			`[virtual]`

Detaches MFC control from CGrid and destroys it.

Parameters:

`[in]`	grid	CGrid object
`[in]`	hItem	Handle of a line in CGrid
`[in]`	column	Column in the grid

Returns:: True if the control has been succesfully detached and destroyed.

Implements IControlReflector.

bool CanDrawControl	(	CGridCell &	cell,
		const CPaintContext &	paintContext,
		UINT	paintFilter
	)			`[virtual]`

Indicates that a control should be painted in CGrid painting routine.

Reflectors create their underlying controls during edit in place operation. CGrid doesn't create MFC controls up to the user starts edit in place operations. Nevertheless while the mouse is moving it is desirable to highlight the control where the mouse is over, or perform other drawings (for ex. drop button). This drawing can be made only inside CGrid painting routine where CGrid can forward cell drawing into the reflector.

Parameters:

`[in]`	cell	Cell in CGrid
`[in]`	paintContext	Nested information to process drawing.
`[in]`	paintFilter	Current paint filter applied to draw a cell.

Returns:: True, if the reflector customizes drawing. Otherwise false.

Implements IControlReflector.

void PostPaintCell	(	CGridCell &	cell,
		const CPaintContext &	paintContext,
		UINT	paintFilter
	)			`[virtual]`

Paints dropdown or spin buttons to the right of the cell.

Parameters:

`[in]`	cell	Cell in CGrid
`[in]`	paintContext	Nested information to process drawing.
`[in]`	paintFilter	Current paint filter applied to draw a cell.

Implements IControlReflector.

bool CanActivateOnThumbClick	(	const CEditInPlaceContext &	context,
		const Common::CFormat *	format
	)			const `[virtual]`

Indicates that MFC control can be activated if the user clicks on dropdown or spin button painted in the cell.

Parameters:

`[in]`	context	Indicates the cell, where the control is attached.
`[in]`	format	Format object, that permits to populate MFC control.

Returns:: True if CGrid can activate edit in place MFC control. Otherwise false.

Implements IControlReflector.

CWnd * GetControl ( ) [virtual]

Gets datetime MFC control.

Returns:: gets CEmbeddedDateTimeCtrl type MFC control if it exists. Otherwise zero.

Implements IControlReflector.
