ClipToFit(TDes &, const CFont &, TInt, TChar)

IMPORT_C voidClipToFit(TDes &aBuffer,
const CFont &aFont,
TIntaMaxWidthInPixels,
TCharaAlternativeEnd =  KTextUtilClipEndChar
)[static]

Clips text to fit into a maximum width.

If the text is too wide to fit in the width when displayed in aFont, it is truncated and the specified character (by default, a horizontal ellipsis) is appended to it.

Parameters

TDes & aBufferA buffer containing the text to clip.
const CFont & aFontThe font.
TInt aMaxWidthInPixelsThe maximum width in pixels.
TChar aAlternativeEnd =  KTextUtilClipEndChar The Unicode character to append to the buffer if truncated. By default, this is the horizontal ellipsis.

ColumnText(TPtrC &, TInt, const TDesC *, TChar)

IMPORT_C TIntColumnText(TPtrC &aColumnText,
TIntaColumn,
const TDesC *aSourceText,
TCharaColumnSeparator =  KColumnListSeparator
)[static]

Gets a portion of text from a descriptor, corresponding to a requested column.

Parameters

TPtrC & aColumnTextOn return, set to the portion of aSourceText that corresponds to the column aColumn.
TInt aColumnThe column to extract. The first column is numbered zero.
const TDesC * aSourceTextThe source text string that contains one or more column separators.
TChar aColumnSeparator =  KColumnListSeparator The character used in aSourceText to separate the columns. By default, a tab character.

TruncateToNumChars(TDes &, TInt)

IMPORT_C voidTruncateToNumChars(TDes &aBuffer,
TIntnumChars
)[static]

Truncates text to a number of characters.

If truncation is required (because aBuffer contains more than numChars characters), an ellipsis is added to the text as the last character.

Parameters

TDes & aBufferOn return, contains the truncated text.
TInt numCharsThe number of characters.
