GUI Elements

The KwikPeg Library includes a number of commonly required drawing components from which your application GUI can be created. Many of these components are optional and, if not used, will not even be present in your final system.

Drawing Primitives

The KwikPeg Library provides a wide range of drawing services from which to choose. Many of the services are optional and, if not used, will not even be present in your final system.

While KwikPeg applications rely primarily on KwikPeg class library objects for window and control drawing, it is often useful to perform custom drawing. For this reason all KwikPeg drawing primitives can be invoked at any time by your application. The following lists summarize some, but not all, of the KwikPeg drawing primitives which are at your disposal.

	Capture		Captures an area of the screen
	EndDraw		Ends a sequence of drawing operations
	Invalidate		Make a screen region ready for drawing
	ResetPalette		Restores default palette
	Restore		Restore previously captured screen area
	SetPalette		Allow loading custom palette
	Text and Fonts
	DeleteFont		Delete font created with MakeFont
	DrawText		Any color, position, font, transparent background or fill
	MakeFont		Create bitmapped font from vector font
	TextHeight		Returns height of string in current font, in pixels
