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?
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
component, widget, widgetadaptor, extendedclass
