CDesktop Class Reference

Provides a set of basic drawing primitives The common parameters of all methos are as follows:

• aFrameBuffer: A reference to a MFrameBuffer to draw on
• aX, aXFrom, aXTo: X coordinate
• aY, aYFrom, aYTo: Y coordinate
• aColor: TColor to draw with The beginning of coordinate system (the (0,0) point) is the top left corner of the screen.

Public Types
typedef unsigned int	TColor
Static Public Member Functions
TColor	GetNearestColor (unsigned int aR, unsigned int aG, unsigned int aB)
	Returns the nearest TColor to given RGB values The return value depends from the color depth of the screen of current device.
void	PutPixel (MFrameBuffer &aFrameBuffer, unsigned int aX, unsigned int aY, TColor aColor)
	Puts the pixel with given color to given coordinates.
TColor	GetPixel (MFrameBuffer &aFrameBuffer, unsigned int aX, unsigned int aY)
	Reads the pixel value for pixel with given coordinates.
void	HLine (MFrameBuffer &aFrameBuffer, unsigned int aXFrom, unsigned int aY, unsigned int aXTo, TColor aColor)
	Draws a horizontal line.
void	VLine (MFrameBuffer &aFrameBuffer, unsigned int aX, unsigned int aYFrom, unsigned int aYTo, TColor aColor)
	Draws a vertical line.
void	Line (MFrameBuffer &aFrameBuffer, unsigned int aXFrom, unsigned int aYFrom, unsigned int aXTo, unsigned int aYTo, TColor aColor)
	Draws a line It's advisory to use HLine() and VLine() for drawing horizontal and vertical lines because they are more efficient.
void	Rect (MFrameBuffer &aFrameBuffer, unsigned int aXFrom, unsigned int aYFrom, unsigned int aXTo, unsigned int aYTo, TColor aColor)
	Draws a rectangle.
void	RectFill (MFrameBuffer &aFrameBuffer, unsigned int aXFrom, unsigned int aYFrom, unsigned int aXTo, unsigned int aYTo, TColor aColor, unsigned int aRounding)
	Draws a filled rectangle with or without rounded corners.

Detailed Description

Provides a set of basic drawing primitives The common parameters of all methos are as follows:

• aFrameBuffer: A reference to a MFrameBuffer to draw on
• aX, aXFrom, aXTo: X coordinate
• aY, aYFrom, aYTo: Y coordinate
• aColor: TColor to draw with The beginning of coordinate system (the (0,0) point) is the top left corner of the screen.

Warning:

CDesktop checks whether given coordinates are in valid range. If they are not, the library asserts and the application is terminated

Member Function Documentation

CDesktop::TColor CDesktop::GetNearestColor (  unsigned int  aR, unsigned int  aG, unsigned int  aB )  [inline, static]

Returns the nearest TColor to given RGB values The return value depends from the color depth of the screen of current device. Warning: Currently only 16bpp is implemented

void CDesktop::RectFill (  MFrameBuffer &  aFrameBuffer, unsigned int  aXFrom, unsigned int  aYFrom, unsigned int  aXTo, unsigned int  aYTo, TColor  aColor, unsigned int  aRounding )  [static]

Draws a filled rectangle with or without rounded corners. Parameters: aFrameBuffer  A reference to a MFrameBuffer to draw on aXFrom  X coordinate to draw the rectangle from aYFrom  Y coordinate to draw the rectangle from aXTo  X coordinate to draw the rectangle to aYTo  Y coordinate to draw the rectangle to aColor  Color to fill the rectangle with aRounding  Defines the radius for rounding corners. Should be in range from 0 (no rounding) to 4
