NAME

itcl::component - define components for extendedclass, widget or widgetadaptor

Parts of this description are "borrowed" from Tcl extension [snit], as the functionality is mostly identical.  

WARNING!

This is new functionality in [incr Tcl] where the API can still change!!  

SYNOPSIS

public component comp ?-inherit?
protected component comp ?-inherit?
private component comp ?-inherit?



 

DESCRIPTION

The component command is used inside an [incr Tcl] extendedclass/widget/widgetadaptor definition to define components.

Explicitly declares a component called comp, and automatically defines the component's instance variable.

If the -inherit option is specified then all unknown methods and options will be delegated to this component. The name -inherit implies that instances of this new type inherit, in a sense, the methods and options of the component. That is, -inherit yes is equivalent to:


component mycomp
delegate option * to mycomp
delegate method * to mycomp
