Detailed Description

Graphic class.

Library: views

An IlvTransparentIcon object appears as an image that may have a transparent background. An IlvTransparentIcon may have transparent areas if its bitmap is monochrome, or has a mask (see IlvBitmap::getMask). Pixels in the monochrome source bitmap, or in the bitmap mask, that have a zero value do not affect the destination port when the drawing is performed. The other pixels indicate an opaque drawing of the source bitmap.
In the figure below, the transparent regions of the bitmap let the background pattern show through. This process works only for monochrome bitmaps or colored bitmaps that have either a transparency mask or a transparent color index.

Constructor & Destructor Documentation

IlvTransparentIcon() [1/2]

IlvTransparentIcon::IlvTransparentIcon	(	IlvDisplay *	display,
		const IlvPoint &	position,
		IlvBitmap *	bitmap,
		IlvPalette *	palette = 0
	)

First constructor.

This constructor initializes a new IlvTransparentIcon at an indicated location. This icon is initialized with the provided bitmap. If this bitmap is not monochrome and if it has no mask, Rogue Wave Views will call the method IlvBitmap::computeMask on that bitmap so that it can be displayed with transparent areas.

Parameters

display	A pointer to the display object that will display this icon.
position	The top-left position of this icon.
bitmap	The bitmap used by this icon. This bitmap is referenced by the IlvIcon object; therefore, if you modify the bitmap object, the visible aspect of the IlvIcon takes these changes into account. This bitmap is locked in the constructor and unlocked in the destructor.
palette	A pointer to the palette that will be used by this object. If left unspecified or set to 0, the default palette of the display (see IlvDisplay::defaultPalette) will be used.

IlvTransparentIcon() [2/2]

IlvTransparentIcon::IlvTransparentIcon	(	IlvDisplay *	display,
		const IlvPoint &	position,
		IlvBitmap *	bitmap,
		IlvBitmap *	mask,
		IlvPalette *	palette = 0
	)

Second constructor.

This constructor initializes a new IlvTransparentIcon at an indicated location. This icon is initialized with the provided bitmap and the provided mask. This mask is set to the bitmap (by calling IlvBitmap::setMask) in the constructor.

Parameters

display	A pointer to the display object that will display this icon.
position	The top-left position of this icon.
bitmap	The bitmap used by this icon. This bitmap is referenced by the IlvIcon object; therefore, if you modify the bitmap object, the visible aspect of the IlvIcon takes these changes into account. This bitmap is locked in the constructor and unlocked in the destructor.
mask	The mask used by this transparent icon. It must have the same dimensions as bitmap and must be monochrome.
palette	A pointer to the palette that will be used by this object. If left unspecified or set to 0, the default palette of the display (see IlvDisplay::defaultPalette) will be used.

Member Function Documentation

getMask()

IlvBitmap* IlvTransparentIcon::getMask

(

)

const

Gets the mask used by this transparent icon.

Returns

A pointer to the mask of the bitmap of this object.

setBitmap()

virtual void IlvTransparentIcon::setBitmap ( IlvBitmap *  bitmap )

virtual

Sets the bitmap of this icon.

Associates the IlvIcon object with a new bitmap. The previous bitmap is unlocked and the new associated bitmap is locked. Note that if you change the bitmap of the icon with one that doesn't have the same dimensions as the previous bitmap, the bounding box of this icon will change.

Parameters

bitmap

The new bitmap that this icon will display.

Reimplemented from IlvIcon.

setMask()

void IlvTransparentIcon::setMask

(

IlvBitmap *

bitmap

)

Sets the mask used by this transparent icon.

Parameters

bitmap

A pointer to the new bitmap that this object should use. If this bitmap is not monochrome and if it doesn't have a mask, Rogue Wave Views calls IlvBitmap::computeMask on this bitmap so that the transparency effect can take place.
