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.
This is new functionality in [incr Tcl] where the API can still change!!
public component comp ?-inherit?
protected component comp ?-inherit?
private component comp ?-inherit?
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:
delegate option * to mycomp
delegate method * to mycomp
