Interface Widget

All Known Subinterfaces:: ArchivedGeometryWidget, Canvas, Graph, Histogram, Raster, ZoomRaster

public interface Widget
extends Create, CreateS, Drop, DropS

Widget base class.. All graphical widgets inherit from the Widget base class. Widget defines most of the behaviour needed: Widgets are created by the user with a particular parent, and then "pack"ed in order to draw them on the screen. All widgets have three essential things: a widget name used when running Tcl code, an Objective C name when sending messages from Tcl to those objects, and a parent.
