parbox ->alignment: {left,right,center,justify}

Alignment of text in box. After parbox->compute has filled a line, this attribute defines the placements of the hbox objects in the physical line. The meaning of left, right and center are obvious. The value justtify implies a straight right and left margin.

Inherits description from: parbox-alignment

parbox ->append: hbox

Append a hbox. See also parbox->cdata.

parbox ->auto_crop: bool

Inherits description from: parbox-auto_crop

parbox ->cdata: cdata=string, style=[style], space=[hbox], ignore_blanks=[{none,leading,trailing,both}]

Append a text by breaking it into words and appending a sequence of tbox objects and hbox objects representing spaces. The name of this method is inspired by SGML, where CDATA is used to declare character data.

If ignore_blanks is leading, first all leading blank characters are skipped. Words encountered in the string are added as instances of the class tbox using the specified style. Sequences of spaces, tabs and newlines are mapped to a single hbox object. If the space argument is provided, this is used for representing these spaces, otherwise a default stretchable hbox object is created with the dimensions of a space in the current font.

See also parbox->append, tbox->initialise and class hbox.

parbox ->geometry: x=[int], y=[int], width=[int], height=[int]

Modify the size and location of the parbox object. The graphical<-height of a parbox is always defined by the parbox<-line_width and the content. If width is specified, the parbox changes its parbox<-line_width trying to fullfil the requested width. It will then adjust the graphical<-width and graphical<-height accordingly.

Specifying an explicit graphical<-width sets parbox<-auto_crop to @off.

parbox ->initialise: width=[int], alignment=[{left,center,right,justify}], content=hbox ...

Create a new parbox object from its parbox<-line_width and parbox<-alignment.

parbox ->line_width: int

Maximum width of a textline in the parbox object. This method is automatically invoked of the parbox->geometry of the parbox is changed.

If the parbox->line_width is changed, the parbox will sent the message graphical->container_size_changed to each embedded graphical object. This mechanism allows for defining the width of a graphical in terms of the width of the paragraph.
