Member Functions Documentation

CreateContext(CGraphicsContext *&)

TInt CreateContext ( CGraphicsContext *& aGC ) [virtual]

Creates a graphics context for the device.

Parameters

CGraphicsContext *& aGC On return, contains a pointer to the created graphics context.

DisplayMode()

TDisplayMode DisplayMode ( ) const [virtual]

Get the height of a font in twips.

The font is identified by typeface and height.

The value returned is rounded up or down to the nearest font height in twips.

Parameters

TInt aTypefaceIndex An index identifying the typeface, in the range: 0 to (NumTypefaces() - 1).
TInt aHeightIndex An index identifying the font height, in the range: 0 to (iNumHeights - 1). Note that iNumHeights is in the TTypefaceSupport object returned by TypefaceSupport().

GetNearestFontInPixels(CFont *&, const TFontSpec &)

TInt GetNearestFontInPixels ( CFont *& aFont,
const TFontSpec & aFontSpec
)

Parameters

CFont *& aFont
const TFontSpec & aFontSpec

GetNearestFontInTwips(CFont *&, const TFontSpec &)

TInt GetNearestFontInTwips ( CFont *& aFont,
const TFontSpec & aFontSpec
) [virtual]

Parameters

CFont *& aFont
const TFontSpec & aFontSpec

GetNearestFontToDesignHeightInPixels(CFont *&, const TFontSpec &)

TInt GetNearestFontToDesignHeightInPixels ( CFont *& aFont,
const TFontSpec & aFontSpec
)

Parameters

CFont *& aFont
const TFontSpec & aFontSpec

GetNearestFontToDesignHeightInTwips(CFont *&, const TFontSpec &)

TInt GetNearestFontToDesignHeightInTwips ( CFont *& aFont,
const TFontSpec & aFontSpec
) [virtual]

Parameters

CFont *& aFont
const TFontSpec & aFontSpec

GetNearestFontToMaxHeightInPixels(CFont *&, const TFontSpec &, TInt)

TInt GetNearestFontToMaxHeightInPixels ( CFont *& aFont,
const TFontSpec & aFontSpec,
TInt aMaxHeight
)

Parameters

CFont *& aFont
const TFontSpec & aFontSpec
TInt aMaxHeight

GetNearestFontToMaxHeightInTwips(CFont *&, const TFontSpec &, TInt)

TInt GetNearestFontToMaxHeightInTwips ( CFont *& aFont,
const TFontSpec & aFontSpec,
TInt aMaxHeight
) [virtual]

Parameters

CFont *& aFont
const TFontSpec & aFontSpec
TInt aMaxHeight

GetPalette(CPalette *&)

TInt GetPalette ( CPalette *& aPalette ) const [virtual]

Gets the device's current palette.

This function is only supported if the device has a modifiable palette, which can be determined by calling PaletteAttributes() .

Parameters

CPalette *& aPalette On return, holds the device's current palette.

HorizontalPixelsToTwips(TInt)

TInt HorizontalPixelsToTwips ( TInt aPixels ) const [virtual]

Parameters

TInt aPixels

HorizontalTwipsToPixels(TInt)

TInt HorizontalTwipsToPixels ( TInt aTwips ) const [virtual]

Parameters

TInt aTwips

NewL(CWsScreenDevice *)

CPrintPreviewDevice * NewL ( CWsScreenDevice * aWinDevice ) [static]

Parameters

CWsScreenDevice * aWinDevice

NumTypefaces()

TInt NumTypefaces ( ) const [virtual]

Gets the number of typefaces supported by the graphics device.

PaletteAttributes(TBool &, TInt &)

void PaletteAttributes ( TBool & aModifiable,
TInt & aNumEntries
) const [virtual]

Gets the palette attributes of the device.

Parameters

TBool & aModifiable On return, holds information on whether or not the device's palette is modifiable (ETrue) or fixed (EFalse).
TInt & aNumEntries On return, holds the number of entries in the device's palette.

ReleaseFont(CFont *)

void ReleaseFont ( CFont * aFont ) [virtual]

Parameters

SetBandRect(const TRect &)

void SetBandRect ( const TRect & aRect ) [inline]

Parameters

const TRect & aRect

SetPalette(CPalette *)

void SetPalette ( CPalette * aPalette ) [virtual]

Sets the device's palette.

Setting the palette is only possible if the device has a modifiable palette, which can be determined by calling PaletteAttributes() .

Parameters

CPalette * aPalette The new palette for the device.

SetPanelPos(const TPoint &)

void SetPanelPos ( const TPoint & aPoint ) [inline]

Parameters

const TPoint & aPoint

SetTwipToPixelMapping(const TSize &, const TSize &)
