TCoeTextTypeAdaptor Class Reference

class TCoeTextTypeAdaptor

This class allows the XCoeTextDrawer to draw text that is in the form of a TBidiText object as well as pre-reordered new-line separated plain text descriptors. (The descriptor text is especially useful when using the XCoeTextDrawer together with the FORM component).

This removes the need to implement two versions of the DrawText() method.

Constructor & Destructor Documentation

TCoeTextTypeAdaptor(const TDesC &)

IMPORT_C

TCoeTextTypeAdaptor

(

const TDesC &

aText

)

Constructor taking a plain descriptor as parameter. The directionality of the text separated with '' must always be left-to-right display order.

Parameters

const TDesC & aText

The text wrapped by the TCoeTextTypeAdaptor.

TCoeTextTypeAdaptor(const TBidiText &)

IMPORT_C

(

const TBidiText &

aText

)

Constructor taking a TBidiText object as parameter.

Parameters

const TBidiText & aText

The text wrapped by the TCoeTextTypeAdaptor.

IMPORT_C TBool

HasRightToLeftDirectionality

(

)

const

This function checks the directionality of the text.

LineOfText(TInt, TInt &, const CFont &)

IMPORT_C TPtrC	LineOfText	(	TInt	aLineNumber,
			TInt &	aWidthInPixels,
			const CFont &	aFont
		)	const

Extracts a line of text. The width (in pixels) of the line is returned in aWidthInPixels.

Parameters

TInt aLineNumber	Zero-based line number.
TInt & aWidthInPixels	The width of the line of text.
