CCleanupStackableFont Class Reference

class CCleanupStackableFont : public CBase

Wraps a font (CFbsFont) object that can be pushed onto the cleanup stack.

By default, the cleanup stack only handles CBase-derived classes, and untyped (TAny*) objects that can be cleaned up by a simple memory free call. Fonts must also be released, which this class handles automatically in its destructor.

The font is initialised from a resource file, and can be identified by name or UID.

Font()

IMPORT_C CFbsFont &

Font

(

)

const

Gets the font stored in this object.

The caller does not take ownership.

NewByNameL(TResourceReader &, CWsScreenDevice &)

IMPORT_C CCleanupStackableFont *	NewByNameL	(	TResourceReader &	aReader,
			CWsScreenDevice &	aScreenDevice
		)	[static]

Allocates and constructs a new CCleanupStackableFont.

aReader should be initialised to read a resource of type NAMED_FONT.

Parameters

TResourceReader & aReader	The resource reader to use.
CWsScreenDevice & aScreenDevice	The screen device.

NewByNameLC(TResourceReader &, CWsScreenDevice &)

IMPORT_C CCleanupStackableFont *	NewByNameLC	(	TResourceReader &	aReader,
			CWsScreenDevice &	aScreenDevice
		)	[static]

Allocates and constructs a new CCleanupStackableFont, leaving it on the cleanup stack.

aReader should be initialised to read a resource of type NAMED_FONT.

Parameters

TResourceReader & aReader	The resource reader to use.
CWsScreenDevice & aScreenDevice	The screen device.

NewL(TResourceReader &, CWsScreenDevice &)

IMPORT_C CCleanupStackableFont *	NewL	(	TResourceReader &	aReader,
			CWsScreenDevice &	aScreenDevice
		)	[static]

Allocates and constructs a new CCleanupStackableFont.

aReader should be initialised to read a resource of type FONT.

Parameters

TResourceReader & aReader	The resource reader to use.
CWsScreenDevice & aScreenDevice	The screen device.

NewLC(TResourceReader &, CWsScreenDevice &)

IMPORT_C CCleanupStackableFont *	NewLC	(	TResourceReader &	aReader,
			CWsScreenDevice &	aScreenDevice
		)	[static]

Allocates and constructs a new CCleanupStackableFont, leaving it on the cleanup stack.

aReader should be initialised to read a resource of type FONT.

Parameters

TResourceReader & aReader	The resource reader to use.
CWsScreenDevice & aScreenDevice	The screen device.

NewLC(TBool, TResourceReader &, CWsScreenDevice &)

CCleanupStackableFont *	NewLC	(	TBool	aByUid,
			TResourceReader &	aReader,
			CWsScreenDevice &	aScreenDevice
		)	[private, static]

Parameters

TBool aByUid
TResourceReader & aReader
CWsScreenDevice & aScreenDevice

TakeOwnershipOfFont()

IMPORT_C CFbsFont *

TakeOwnershipOfFont

(

)

Gets the font stored in this object.

The caller takes ownership of the returned font.
