A window whose contents are backed up, so that the window never becomes invalid, and therefore never needs to be redrawn except at application request.
The colour with which to fill the parts of the view rectangle in which text (and paragraph fill colour, if one has been set) cannot appear. Examples of such areas are below the last line of the document and in the label and line cursor margins. May also be used to fill the left text margin, if one has been set.

An area of physical address space reserved for a particular type of memory (e.g. RAM, ROM, I/O) and which may be empty or only partially filled
The band of frequencies of a signal before it is modulated for transmission at another frequency.
Application Engines : In an anniversary entry, this allows the application to display a number of years between the base year and the current anniversary.
Text Content : A pointer to the format layer whose attributes are inherited by another layer. To find out a character or paragraph's effective formatting, all based-on links must be examined, beginning at the format layer upon which all other layers are based.

The baseline of a character is the notional line that splits the descent of a character from its ascent (see Character cell metrics (ascent, descent, height and baseline)).
See also: character cell ascent character cell descent
The perpendicular distance from the baseline of a font to another parallel line, such as the underline, strikethrough, superscript or subscript position (see Underlining and baseline offsets).

Refers to a short-range radio technology used to simplify communications among Net devices and between devices on the Internet. It also simplifies data synchronisation between Net devices and other comuters.
Standardised by the Bluetooth SIG in the form of the v1.0 Bluetooth Specification.
Converts bitmaps between Windows and Symbian OS formats.
Extension for a Windows bitmap file.

Optional code which runs immediately on reset, before the bootstrap.
A short program, often written in assembler, which gains control when the machine is first powered on. The bootstrap sets up an environment that will allow the Kernel to continue to boot Symbian OS (e.g. setting up memory, I/O devices and creating virtual memory space).
The brush is used, in basic graphics functions, for filling areas drawn with the shape primitives, and also for text background fills.

Brush attributes, in basic graphics functions, are: brush colour, brush origin, brush style.
See also: brush brush origin brush style
The colour which the brush uses for fills.
See also: brush attribute
The point at which the top left corner of the pattern reference tile is positioned.
See also: brush attribute
The style with which the brush fills fillables. This may be null, solid colour, a built-in pattern or a bitmap pattern.
