Prima::TextView Description

Prima::TextView is a rich text browser widget. Prima::TextView is a rich text browser widget.Prima::TextView accepts blocks of formatted text, and provides basic functionality - scrolling and user selection. The text strings are stored as one large text chunk, available by the ::text and ::textRef properties. A block of a formatted text is an array with fixed-length header and the following instructions.A special package tb:: provides the block constants and simple functions for text block access.CapabilitiesPrima::TextView is mainly the text block functions and helpers. It provides function for wrapping text block, calculating block dimensions, drawing and converting coordinates from (X,Y) to a block position. Prima::TextView is centered around the text functionality, and although any custom graphic of arbitrary complexity can be embedded in a text block, the internal coordinate system is used ( TEXT_OFFSET, BLOCK ), where TEXT_OFFSET is a text offset from the beginning of a block and BLOCK is an index of a block.The functionality does not imply any text layout - this is up to the class descendants, they must provide they own layout policy. The only policy Prima::TextView requires is that blocks' BLK_TEXT_OFFSET field must be strictly increasing, and the block text chunks must not overlap. The text gaps are allowed though.A text block basic drawing function includes change of color, backColor and font, and the painting of text strings. Other types of graphics can be achieved by supplying custom code. Requirements: · Perl
