The Text widget may be customized by subclassing, or by -creating new sources and sinks. Subclassing is described in -detail in Chapter 7; this section will describe only those things that -are specific to the Text widget. Attributes of the Text widget base -class and creating new sources and sinks will be discussed. -.LP -The Text widget is made up of a number of different pieces, with the -Text widget as the base widget class. It and the AsciiText widget are -the only true "widgets" in the Text widget family. The other pieces -(sources and sinks) are X Toolkit objects and have no window -associated with them. No source or sink is useful unless assigned to -a Text widget. -.LP -Each of the following pieces of the Text widget has a specific purpose, -and will be, or has been, discussed in detail in this chapter: -.IN "Text widget" "" -.IP \fBText\fP 15 -This is the glue that binds everything else together. This widget reads -the text data from the source, and displays the information in the sink. -All translations and actions are handled in the Text widget itself. -.IN "TextSink object" "" -.IP \fBTextSink\fP 15 -This object is responsible for displaying and clearing the drawing area. -It also reports the configuration of the window that contains the -drawing area. The TextSink does not have its own window; instead it does -its drawing on the Text widget's window. -.IN "TextSrc object" "" -.IP \fBTextSrc\fP 15 -This object is responsible for reading, editing and searching through the -text buffer. -.IN "AsciiSink object" "" -.IP \fBAsciiSink\fP 15 -This object is a subclass of the TextSink and knows how to display -ASCII text. Support has been added to display any 8-bit character set, given -the font. -.IN "MultiSink object" "" -.IP \fBMultiSink\fP 15 -This object is a subclass of the TextSink and knows how to display -font sets. -.IN "AsciiSrc object" "" -.IP \fBAsciiSrc\fP 15 -This object is a subclass of the TextSrc and knows how to read strings -and files. -.IN "MultiSrc object" "" -.IP \fBMultiSrc\fP 15 -This object is a subclass of the TextSrc and knows how to read strings -and multibyte files, converting them to wide characters based on locale. -.IN "AsciiText widget" "" -.IP \fBAsciiText\fP 15 -This widget is a subclass of the Text widget. When created, the AsciiText -automatically creates and attaches either an AsciiSrc and AsciiSink, or a -MultiSrc and MultiSink, to itself.
