(

)

[static]

Creates an object of type CTransparentUtil

Returns:

New CTransparentUtil object

Definition at line 53 of file transparent_util.cpp.

void CTransparentUtil::ConstructL

)

Initializations for window server session, screen device, graphics context window group, background window, foreground window, event handler, blank window and active object for delay. KErrNoMemory System-wide error codes.

Definition at line 93 of file transparent_util.cpp.

void CTransparentUtil::ClearWindow	(	RWsSession &	aSession,
		RWindow &	aWindow,
		CWindowGc *	aGc,
		TRgb	aColor
	)

Clears the window to the selected colour

Parameters:

	aSession	The window server session
	aWindow	The handle to the window
	aGc	Graphics context of the window
	aColor	Colour to be used when the window is cleared

Definition at line 217 of file transparent_util.cpp.

void CTransparentUtil::DrawWindow	(	RWindow &	aWindow,
		TRgb	aColor1,
		TRgb	aColor2,
		TRect	aRect,
		const TDesC &	aText
	)

Clears the window to the selected colour and redraws the background window

Parameters:

	aWindow	The handle to the window
	aColor1	Colour to be used when the window is cleared
	aColor2	Colour in which the window must be drawn
	aRect	Area to be drawn

Definition at line 171 of file transparent_util.cpp.

void CTransparentUtil::DrawWindowRegion	(	RWindow &	aWindow,
		TRgb	aColor1,
		TRgb	aColor2,
		TRect	aChopRect,
		TRect	aRect,
		const TDesC &	aText,
		const TPoint &	aPoint
	)

Clears the window to the selected colour and redraws the region of the foreground window

Parameters:

	aWindow	The handle to the window
	aColor1	Colour to be used when the window is cleared
	aColor2	Colour in which the window must be drawn
	aChopRect	Region of the foreground window to be drawn.
	aRect	Area to be drawn
	aText	Text to be drawn.
	aPoint	Point at which text should be drawn.

Definition at line 314 of file transparent_util.cpp.

void CTransparentUtil::TransparencyVarianceL

(

)

Creates an opaque background window and draws a circle onto it. Creates a transparent foreground window and draws an ellipse onto it. Waits for button press events and starts the active scheduler upon the corresponding button being pressed. System-wide error codes.

Definition at line 197 of file transparent_util.cpp.

void CTransparentUtil::TransparentRegionL

(

)

Creates an transparent foreground window with some region of it made opaque. Waits for button press events and starts the active scheduler upon the corresponding button being pressed. System-wide error codes.

Definition at line 263 of file transparent_util.cpp.

TBool CTransparentUtil::DoChangeTransparencyL

(

)

Varies the alpha value of the window up to 255 i.e. until the window turns opaque

Returns:

ETrue if the alpha value is less than its maximum limit otherwise return EFalse.
