Class TCoeTextTypeAdaptor

class TCoeTextTypeAdaptor;

Description

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.

IMPORT_C TCoeTextTypeAdaptor(const TDesC &aText);

Description

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

Parameters

const TDesC16 &aText The text wrapped by the TCoeTextTypeAdaptor.

IMPORT_C TCoeTextTypeAdaptor(const TBidiText &aText);

Description

Constructor taking a TBidiText object as parameter.

Parameters

const TBidiText &aText The text wrapped by the TCoeTextTypeAdaptor.

IMPORT_C TInt NumberOfLines() const;

Description

Calculates the number of lines in the text.

Return value

TInt TInt number of lines in the object

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

Description

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. const CFont &aFont The font that will be used to draw the text.

Return value

TPtrC16 TPtrC line of text

IMPORT_C TBool HasRightToLeftDirectionality() const;

Description

This function checks the directionality of the text.

Return value

TBool ETrue if the text has right-to-left directionality, EFalse if it has left-to-right directionality.
