Detailed Description

Gadget class.

Library: dbgadget

The IliMemoryDataSource class defines a data source whose table is a memory table.

See also: IliMemoryTable.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass IliDataSource.

Constructor & Destructor Documentation

§ IliMemoryDataSource()

IliMemoryDataSource::IliMemoryDataSource	(	IlvDisplay *	display,
		const IlvPoint &	at,
		IlUShort	thickness = `IlvDefaultGadgetThickness`,
		IlvPalette *	palette = `0`
	)

The constructor initializes a memory data source.

Parameters

display	The display.

palette	The palette.

Member Function Documentation

§ getBitmap()

virtual IlvBitmap* IliMemoryDataSource::getBitmap ( ) const

virtual

Returns the bitmap that is displayed during the design phase in Rogue Wave Views Data Access.

Returns: The bitmap.

Reimplemented from IliDataSource.

§ getMemoryTable() [1/2]

const IliMemoryTable* IliMemoryDataSource::getMemoryTable ( ) const

Returns the memory table.

Returns: The memory table of the data source.

§ getMemoryTable() [2/2]

IliMemoryTable* IliMemoryDataSource::getMemoryTable ( )

Returns the memory table.

Returns: The memory table of the data source.

§ setMemoryTable()

void IliMemoryDataSource::setMemoryTable	(	IliMemoryTable *	table,
		IlBoolean	owner = `IlTrue`
	)

Sets the memory table.

Sets the memory table of the data source to table. If owner is IlTrue, the data source becomes the owner of the table.
