Tcl/Tk in a Nutshell

Name

Primitive

tixPrimitive pathname [option value...]

The tixPrimitive command creates a new tixPrimitive mega-widget named pathName. The tixPrimitive is a virtual base class that provides a root widget that derived mega-widgets use as a base container upon which to build. In fact, pathName is used as the pathName of the base widget. Unless overridden by a derived class, this base widget is a frame widget. The only class in the Tix core mega-widgets that overrides this is the tixShell class, which uses a top-level widget for its root.

Widget-Specific Options

The tixPrimitive mega-widget supports the following options, which are simply passed to the underlying root widget. See the frame widget command in Chapter 3.

-background	-borderwidth	-cursor
-height	-highlightbackground	-highlightcolor
-highlightthickness	-relief	-takefocus
-width

The tixPrimitive mega-widget supports the following special option to make it easy for descendant classes to pass options to subwidgets:

-options optionList (options, Options)

List of resource options and values to apply to mega-widget. Each odd element is the resource specification relative to the mega-widget. Each following even element is its value. This option is mainly used to configure a mega-widget's subwidgets at creation time. For example:

tixComboBox .cb -label Color: -dropdown true \
    -options { listbox.height 4 label.width 10 label.anchor e }
